SUMMARY OF MATERIAL ACCOUNTING POLICIES

SUMMARY OF MATERIAL ACCOUNTING POLICIES

2. SUMMARY OF MATERIAL ACCOUNTING POLICIES

Basis of presentation

These Annual Financial Statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (“IASB”).

Basis of measurement

These Annual Financial Statements were prepared on the historical cost basis except for certain financial instruments that are measured at fair value at the end of the reporting period (see Note 19).

Presentation and functional currency

These Annual Financial Statements are presented in Canadian dollars which is GFL’s functional currency.

Basis of consolidation

Subsidiaries are entities controlled by GFL. Control exists when GFL has power over an entity, exposure or rights to variable returns from GFL’s involvement with the entity, and the ability to use its power over the entity to affect the amount of GFL’s returns. The financial accounts and results of subsidiaries are included in these Annual Financial Statements of GFL from the date that control commences until the date that control ceases.

When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with GFL’s accounting policies. All intercompany assets and liabilities, equity, income, expenses and cash flows relating to transactions between GFL and its subsidiaries are eliminated in full on consolidation.

Business combinations

Acquisitions of subsidiaries and businesses are accounted for using the acquisition method with the results of operations consolidated with those of GFL from the date of acquisition. The consideration for each acquisition is measured as the aggregate of the fair values of assets given, liabilities incurred or assumed and the equity instruments issued by GFL in exchange for control of the acquired company or business. Acquisition-related costs are recognized in the consolidated statement of operations as incurred.

GFL’s growth strategy is to focus on generating organic growth from all of its operating segments. In addition to organic growth, GFL deploys an active acquisition strategy involving the integration of acquired businesses into each of its operating segments through integration of property and equipment, back office functions, improving route density and realignment of disposal alternatives to effect synergies and maximize profits. Goodwill arising from acquisitions is largely attributable to the assembled workforce of the acquisitions, the potential synergies with the acquiree, and intangible assets that do not qualify for separate recognition.

The determination of the fair values of acquired intangible assets and acquired landfill assets requires GFL to make significant estimates and assumptions. The significant assumptions used to value acquired intangible assets and acquired landfill assets include, among others, future expected cash flows and discount rate.

Equity accounting for joint arrangements and associates

Associates are all entities over which GFL has significant influence but not control or joint control. Investments in associates are accounted for using the equity method of accounting after initially being recognized at cost.

Joint arrangements are classified as either joint operations or joint ventures. The classification depends on contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. Interests in joint ventures are accounted for by GFL using the equity method, after initially being recognized at cost.

An investment is considered to be impaired if there are objective evidences of impairments, as a result of one or more events that occurred after the initial recognition, and those events have negative impacts on the future cash flows of the investment that can be reliably estimated. The investment is reviewed at each balance sheet date to determine whether there is any indication of impairment.

Property and equipment

Property and equipment are stated at cost, less accumulated depreciation and impairment. Assets are depreciated to residual values over their estimated useful lives, with depreciation commencing when an asset is ready for use. Significant parts of property and equipment that have different depreciable lives are depreciated separately. Judgment is used in determining the appropriate level of componentization.

Depreciation is computed on a straight-line basis, unless otherwise stated, using the following useful lives:


Type of property and equipment		Depreciation term
Buildings and improvements		10 to 30 years or term of lease
Landfills		Units of production
Vehicles		10 to 20 years
Machinery and equipment		3 to 20 years
Containers		5 to 10 years
Right-of-use assets		Shorter of lease term or life of underlying asset(s)

The costs of repair and maintenance activities are recognized in the consolidated statement of operations as incurred. Distinguishing major inspections and overhaul from repairs and maintenance in determining which costs are capitalized is a matter of management judgement.

An item of property and equipment is de-recognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on de-recognition of the asset (calculated as the difference between net disposal proceeds and the carrying amount of the asset) is included as a gain or loss in the consolidated statement of operations in the period the asset is de-recognized.

Property and equipment are reviewed at the end of each reporting period to determine whether there is any indication of impairment. If the possibility of impairment is indicated, GFL will estimate the recoverable amount of the asset and record any impairment loss in the consolidated statement of operations.

Assets under development are not depreciated until they are available for use.

Landfill assets

Landfill assets represent the cost of landfill airspace, including original acquisition cost and landfill construction and development costs, incurred during the operating life of the site. Landfill assets also include capitalized landfill closure and post-closure costs, net of accumulated amortization, and the cost of either new or landfill expansion permits.

The original cost of landfill assets, together with incurred and projected landfill construction and development costs, is amortized on a per unit basis as landfill airspace is consumed.

Landfill assets are amortized over their total available disposal capacity representing the sum of estimated permitted airspace capacity (having received the final permit from the governing authorities) plus future permitted airspace capacity, representing an estimate of airspace capacity that management believes is probable of being permitted based on the following criteria:

●

Personnel are actively working to obtain the permit or permit modifications necessary for expansion of an existinglandfill, and progress is being made on the project;

●

It is probable that the required approvals will be received within the normal application and processing periods for approvals in the jurisdiction in which the landfill is located;

●

GFL has a legal right to use or obtain land associated with the expansion plan;

●

There are no significant known political, technical, legal or business restrictions or issues that could impair the success of the expansion effort;

●

Management is committed to pursuing the expansion; and

●

Additional airspace capacity and related costs have been estimated based on the conceptual design of the proposed expansion.

GFL has been successful in receiving approvals for expansions pursued; however, there can be no assurance that GFL will be successful in obtaining approvals for landfill expansions in the future.

Intangible assets

Intangible assets are stated at cost, less accumulated amortization and impairment, and consist of customer lists, municipal and other commercial contracts, trade name, licenses and permits, non-compete agreements and Certificates of Approvals or Environmental Compliance Approvals (“C of As”). C of As provide GFL with certain waste management rights in the province or state of issuance. C of As that do not expire are considered to have an indefinite life and therefore are not subject to amortization. C of As that relate to a leased facility are amortized over the lease term.

Amortization is based on the estimated useful life using the following methods and rates:


Type of intangible asset		Amortization term
Indefinite life C of As		Indefinite
Customer lists and municipal contracts	Straight-line	5 to 10 years
Trade name, definite life C of As and other assets	Straight-line	1 to 15 years
Non-compete agreements	Straight-line	5 years

Intangible assets with indefinite useful lives are tested at least annually, at the cash-generating unit (“CGU”) level for impairment. The assessment of indefinite life is reviewed annually to determine whether the indefinite life assessment continues to be supportable. If not, the change in the useful life assessment from indefinite to finite is made on a prospective basis. Intangible assets with finite lives are amortized over the useful economic life on a straight-line basis and assessed for impairment whenever there is an indication that the intangible asset may be impaired. Amortization expense is included as part of cost of sales.

Goodwill

Goodwill arising on an acquisition of a business represents the excess of the purchase price over the fair value of the net identifiable assets of the acquired business. Goodwill is carried at cost as established at the date of acquisition of the business less accumulated impairment losses, if any.

For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to CGUs based on the lowest level within the entity in which the goodwill is monitored for internal management purposes. The allocation is made to those CGUs that are expected to benefit from the business combination in which the goodwill arose. GFL tests its goodwill for impairment at the operating segment level. Any potential impairment of goodwill is identified by comparing the recoverable amount of a CGU to its carrying value. Goodwill is reduced by the amount of deficiency, if any. If the deficiency exceeds the carrying amount of goodwill, the carrying values of the remaining assets in the CGUs are reduced by the excess on a pro-rata basis. GFL tests goodwill for impairment annually or more frequently if there are indications of impairment.

The recoverable amount of a CGU is the higher of the estimated fair value less costs of disposal or value-in-use of the CGU. In assessing value-in-use, the estimated future cash flows are discounted using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the CGU.

Landfill closure and post-closure obligations

GFL recognizes the estimated liability for an asset retirement obligation (“ARO”) that results from acquisition, construction, development or normal operations in the year in which it is incurred. Costs associated with capping, closing and monitoring a landfill or portions of a landfill, after it ceases to accept waste, are initially measured at the discounted future value of the estimated cash flows over the landfill’s operating life. The operating life represents the period over which the landfill receives waste. This value is capitalized as part of the cost of the related asset and amortized over the asset’s useful life.

The determination of the obligations requires GFL to make significant estimates and assumptions. The significant assumptions include the estimates of future expenditures of landfill capping, closure and post-closure activities, which are prepared by internal and third-party engineering specialists and reviewed at least once annually and consider, amongst other things, regulations that govern each site. The estimated liabilities are valued using present value techniques that consider and incorporate assumptions and considerations marketplace participants would use in the determination of those estimates, including inflation, markups, inherent uncertainties due to the timing of work performed, information obtained from third parties, quoted and actual prices paid for similar work and engineering estimates. Inflation assumptions are based on management’s evaluation of current and future economic conditions and the expected timing of these expenditures. Estimates are discounted applying the risk-free rate, which is a rate that is essentially free of default risk. In determining the risk-free rate, consideration is given to both current and future economic conditions and the expected timing of expenditures.

Revenue recognition

GFL records revenue when control is transferred to the customer which is the time that the service is provided. Revenue is measured based on the consideration specified in a contract with a customer or consideration agreed by a customer. Revenue excludes amounts collected on behalf of third parties. GFL recognizes revenue from the following major sources:

Collection and disposal of solid waste

GFL generates revenue through fees charged for the collection of solid waste including recyclables, from its municipal, residential and commercial and industrial customers. Revenues from these contracts are influenced by a variety of factors including collection frequency, type of service, type and volume or weight of waste and type of equipment and containers furnished to the customer.

Our municipal customer relationships are generally supported by contracts ranging from three to ten years. Our municipal collection contracts provide for fees based upon a per household, per tonne or ton, per lift or per service basis and often provide for annual price increases indexed to the Consumer Price Index (“CPI”), other waste related indices and market costs for fuel. We provide regularly scheduled service to a large percentage of our commercial and industrial customers under contracts with three to five year terms with automatic renewals, volume-based pricing and CPI, fuel and other adjustments. Other commercial and industrial customers are serviced on an “on-call” basis, for which revenue is recognized when the service has been provided.

Certain future variable considerations of long-term customer contracts may be unknown upon entering into the contract, including the amount that will be billed in accordance with annual CPI, market costs for fuel and commodity prices. The amount to be billed is often tied to changes in an underlying base index such as a CPI or a fuel or commodity index, and revenue is recognized once the index is established for the future period. GFL does not disclose the value of unsatisfied performance obligations for these contracts as its right to consideration corresponds directly to the value provided to the customer for services completed to date and all future variable consideration is allocated to wholly unsatisfied performance obligations.

In addition to handling GFL’s own collected waste volumes, its transfer stations, material recovery facilities (“MRFs”), landfills and organic waste processing facilities generate revenue from tipping fees paid to GFL by municipalities and third-party haulers and waste generators, processing fees, and the sale of recycled commodities. GFL also operates MRFs, transfer stations and landfills for municipal owners under a variety of compensation arrangements, including fixed fee arrangements or on a tonnage or other basis. Revenue is recognized at the time service is provided.

Collection and disposal of liquid waste

GFL generates revenue through fees charged for the collection, management, transportation, processing and disposal of a wide variety of industrial and commercial liquid wastes. Revenue is primarily derived from fees charged to customers on a per service, volume and/or hour basis. Revenues from these contracts are influenced by a variety of factors including timing of contract, type of service, type and volume of liquid waste and type of equipment used. Revenue in the liquid waste business is also derived from the stewardship return incentives paid by most Canadian provinces in which GFL has liquid waste operations, as well as from the sale of used motor oil, solvents and downstream products to third parties. The fees received from third parties are based on the market, type and volume of material sold. Revenue is recognized at the time when service is provided. Revenue recognized under these agreements is variable in nature based on volumes and commodity prices at the time of sale, which are unknown at contract inception.

Share-based payments

Share options issued by GFL as remuneration of its key employees, officers, and directors are settled in subordinate voting shares and are accounted for as equity-settled awards.

The fair value of options granted is measured using either the Black-Scholes option pricing model or the Monte Carlo simulation methods, which rely on estimates of the expected risk-free interest rate, expected dividend payments, expected share price volatility, the value of GFL’s shares and the expected average life of the options. GFL believes these models adequately capture the substantive features of the option awards and are appropriate to calculate their fair values.

The fair value of the options determined at the grant date is expensed over the vesting period using an accelerated method of amortization, with a corresponding increase to contributed surplus. Expense related to share-based payments is included as part of selling, general and administrative expense. Upon exercise of options, the amount recognized in contributed surplus for the awards and the cash received upon exercise are recognized as an increase in share capital.

GFL has a long-term incentive plan (“LTIP”) to grant long-term equity-based incentives, including options, performance share units (“PSUs”), restricted share units (“RSUs”), and deferred share units (“DSUs”) to eligible participants. Each award represents the right to receive subordinate voting shares, or in the case of PSUs and RSUs, subordinate voting shares and/or cash, in accordance with the terms of the LTIP.

The fair value of the RSUs and DSUs granted are based on the closing price of the subordinate voting shares on the day prior to the grant. The fair value of the RSUs and DSUs are recognized as compensation expense over the vesting period.

Income taxes

Income tax expense or recovery is comprised of current and deferred income taxes. It is recognized in the consolidated statement of operations, except to the extent that the expense relates to items recognized directly in equity.

A current or non-current tax liability/asset is the estimated tax payable/receivable on taxable income for the period, and any adjustments to taxes payable with respect to previous periods.

The liability method is used to account for deferred tax assets and liabilities, which arise from temporary differences between the carrying amount of assets and liabilities recognized in the consolidated statement of financial position and their corresponding tax basis. The carry forward of unused tax losses and credits are recognized to the extent that it is probable they can be used in the future.

The carrying amount of deferred income tax assets is reviewed at each reporting date and reduced to the extent it is no longer probable that the deferred income tax asset will be recovered.

Deferred income tax assets and liabilities are calculated at the tax rates that are expected to apply when the asset or liability is recovered or settled. Current and deferred tax assets and liabilities are calculated using tax rates that have been enacted or substantively enacted at the end of the reporting date.

Where current tax or deferred tax arises from the initial accounting for a business combination, the tax effect is included in the accounting for the business combination.

Deferred tax income liabilities are offset if a legally enforceable right exists to set off current income tax assets against current income tax liabilities and the deferred tax relates to the same taxable entity and the same taxation authority.

Financial instruments

Classification and measurement

All financial assets and liabilities are recognized initially at fair value plus or minus transaction costs, except for financial instruments at fair value through profit or loss (“FVTPL”), for which transaction costs are expensed.

Debt financial instruments are subsequently measured at FVTPL, fair value through other comprehensive income (“FVTOCI”), or amortized cost using the effective interest rate method. GFL determines the classification of its financial assets based on GFL’s business model for managing the financial assets and whether the instruments’ contractual cash flows represent solely payments of principal and interest on the principal amount outstanding.

GFL’s derivatives designated as a hedging instrument in a qualifying hedge relationship are subsequently measured at FVTOCI. Equity instruments that meet the definition of a financial asset, if any, are subsequently measured at FVTPL or elected irrevocably to be classified at FVTOCI at initial recognition. Derivatives not designated in a qualified hedge relationship are measured at FVTPL.

Financial liabilities are subsequently measured at amortized cost using the effective interest method or at FVTPL in certain circumstances or when the financial liability is designated as such. For financial liabilities that are designated as FVTPL, the amount of change in the fair value of the financial liability that is attributable to changes in GFL’s own credit risk of that liability is recognized in other comprehensive income or loss unless the recognition of the effects of changes in the liability’s credit risk in other comprehensive income or loss would create or enlarge an accounting mismatch in the consolidated statement of operations. The remaining amount of change in the fair value of the liability is recognized in the consolidated statement of operations. Changes in the fair value of a financial liability attributable to GFL’s own credit risk, if any, are recognized in other comprehensive income or loss and are not subsequently reclassified to the consolidated statement of operations; instead, they are transferred to retained earnings, upon de-recognition of the financial liability.

All of GFL’s financial assets are categorized within the amortized cost measurement category. All of GFL’s financial liabilities, with the exception of deferred foreign exchange derivatives and the Purchase Contracts (as defined below), are also categorized within the amortized cost measurement category. Deferred foreign exchange derivatives, which qualify for hedge accounting, are categorized within the FVTOCI category and the Purchase Contracts, which is a financial liability with embedded derivative features, is categorized within the FVTPL category.

Impairment

GFL uses a forward-looking Expected Credit Loss (“ECL”) model to determine impairment of financial assets. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that GFL expects to receive.

For trade receivables, GFL applies the simplified approach and has determined the allowance based on lifetime ECLs at each reporting date. GFL establishes a provision that is based on GFL’s historical credit loss experience, adjusted for forward-looking factors specific to the customers and the economic environment.

Hedge accounting

GFL is exposed to the risk of currency fluctuations and has entered into currency derivative contracts and is exposed to the risk of fuel price fluctuations and has entered into fuel derivative contracts to hedge a portion of this exposure on the basis of planned transactions. Where hedge accounting is applied, the criteria are documented at the inception of the hedge and updated at each reporting date. GFL documents the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking the hedging transactions. GFL also documents its assessment, at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items.

Basis of fair values

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

●

In the principal market for the asset or liability, or

●

In the absence of a principal market, in the most advantageous market for the asset or liability.

GFL uses valuation techniques that it believes are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. All assets and liabilities for which fair value is measured or disclosed are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

Level 1 — quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 — inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3 — are unobservable inputs for the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.

Critical accounting judgments and estimates

The preparation of the Annual Financial Statements in conformity with IFRS requires management to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenue and expense for the period. Such estimates relate to unsettled transactions and events as of the date of the Annual Financial Statements. Accordingly, actual results may differ from estimated amounts as transactions are settled in the future. Estimates and assumptions are reviewed on an ongoing basis. Revisions to estimates are applied prospectively.

The following areas are the critical judgments and estimates that management has made in applying GFL’s accounting policies and that have the most significant effect on amounts recognized in the Annual Financial Statements:

●

Determining the fair value of acquired assets and liabilities in business combinations, specifically the fair value of acquired intangible assets and acquired landfill assets

●

Estimating the amount and timing of the landfill closure and post-closure obligations, specifically the estimated future expenditures associated with landfill capping, closure and post-closure activities

●

Determining the key assumptions for impairment testing for long-lived assets

Foreign currency translation

Functional currency

Items related to GFL’s subsidiaries are measured using the currency of the primary economic environment in which each entity operates (the functional currency). Foreign currency transactions are translated into the functional currency of each entity using the exchange rates prevailing at the date of the transactions or valuation when items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions and from the remeasurement at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the consolidated statement of operations.

Foreign operations

GFL’s foreign operations are conducted through its subsidiaries located in the United States of America (“US subsidiaries”), whose functional currency is the United States dollar.

The assets and liabilities of these US subsidiaries are translated into the presentation currency of GFL using the exchange rate at the reporting date. Revenues and expenses are translated at the average exchange rate for the period. The resulting foreign exchange translation differences are recorded as a currency translation adjustment in other comprehensive income or loss.

New and amended standards adopted

A number of amended standards became applicable for the current reporting period. GFL was not required to change its accounting policies or make retrospective adjustments as a result of adopting the applicable amended standards.

New accounting standards issued but not yet effective

Certain new accounting standards and interpretations have been published that are not mandatory for the current period and have not been early adopted. For those standards and interpretations applicable to GFL, they are not expected to have a material impact on the Annual Financial Statements in future periods.

3. BUSINESS COMBINATIONS AND INVESTMENTS

For the year ended December 31, 2024, GFL acquired 11 businesses, each of which GFL considers to be individually immaterial.

The following table presents the purchase price allocation based on the best information available to GFL to date:


	Year ended December 31,
	2024		2023
Net working capital, including cash acquired of $9.3 million and $6.9 million, respectively	$	6.1	$	(26.4)

Cash paid		591.2		897.8
Contribution from non-controlling interests		—		205.9
Total Consideration	$	591.2	$	1,111.1

In addition to the cash consideration noted above, during the year ended December 31, 2024, GFL paid $30.0 million in additional consideration related to acquisitions from prior years.

GFL finalizes purchase price allocations relating to acquisitions within 12 months of the respective acquisition dates and, as a result, there may be differences between the provisional estimates reflected above and the final acquisition accounting. During the year ended December 31, 2024, GFL finalized the purchase price allocations for certain acquisitions resulting in a decrease in net working capital of $1.8 million, a decrease in property and equipment of $5.8 million, an increase in lease obligations of $2.6 million, an increase in closure and post-closure obligations of $1.3 million, an increase in deferred income tax liabilities of $0.9 million and an increase in goodwill of $12.4 million.

All of the goodwill acquired during the year ended December 31, 2024 ($143.7 million during the year ended December 31, 2023) is expected to be deductible for tax purposes.

Since the respective acquisition dates, revenue and income before income taxes of approximately $83.7 million and $24.6 million, respectively, attributable to the 2024 acquisitions, are included in these Annual Financial Statements.

Pro forma results of operations

If the 2024 acquisitions had occurred on January 1, 2024, the unaudited consolidated pro forma revenue and loss before income taxes for the year ended December 31, 2024 would have been $7,903.2 million and $932.9 million, respectively. The pro forma results do not purport to be indicative of the results of operations which would have resulted had the acquisitions occurred at the beginning of the year, nor are they necessarily indicative of future operating results.

All intangible asset amortization expense is included in cost of sales.

In assessing goodwill and indefinite life intangible assets for impairment at December 31, 2024 and 2023, GFL compared the aggregate recoverable amount of the assets included in CGUs to their respective carrying amounts.

For all CGUs, the recoverable amount was determined based on the value in use by discounting estimated future cash flows from a CGU to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the CGU. Estimated cash flow projections are based on GFL’s one-year budget and five year strategic plan. There was no impairment recorded at the CGU level as at December 31, 2024 and 2023.

The key assumptions used for both periods in determining the recoverable amount for each CGU are as follows:

●

Revenue growth rates – Growth rate of 5.0% was used for the periods covered in the financial projections and is based on historical results and expectations for the forecasted periods.

●

Pre-tax discount rates – The pre-tax discount rate calculation is based on the specific circumstances of the CGU and range from 7.7% to 9.3% (7.7% to 8.6% for the year ended December 31, 2023).

●

Terminal growth value – The cash flows beyond the initial period are extrapolated using a growth rate of 2.3%. Rates are based on market and industry trends researched and identified by management.

●

Capital expenditures – The cash flow forecasts for capital expenditures are based on past experience and include the ongoing capital expenditures required to maintain the business.

In all CGUs, reasonably possible changes to key assumptions would not cause the recoverable amount of each CGU to fall below the carrying value.

The present value of GFL’s future landfill closure and post-closure obligations has been estimated by management based on GFL’s cost, in today’s dollars, to settle closure and post-closure obligations at its landfills, projected timing of these expenditures and the application of discount and inflation rates. GFL used a risk-free discount rate of 3.33% in Canada and 4.78% in the United States as at December 31, 2024 (3.02% in Canada and 4.03% in the United States as at December 31, 2023) and an inflation rate of 2.60% in Canada and 2.96% in the United States (2.60% in Canada and 2.82% in the United States as at December 31, 2023) to calculate the present value of the landfill closure and post-closure obligations. Obligations acquired through business combinations are initially valued at fair value using a credit-adjusted, risk-free discount rate. Reducing the discount rate to the risk-free rate resulted in a one-time increase to the liability of $7.3 million included in the Provisions line item in the table above for the year ended December 31, 2024 ($4.4 million for the year ended December 31, 2023).

The landfill closure and post-closure obligations mature as follows:

Between 2-5 years		197.5
Over 5 years		660.2

Funded landfill post-closure assets

GFL is required to deposit funds into trusts to settle post-closure obligations for landfills in certain jurisdictions. As at December 31, 2024, included in other long-term assets are funded landfill post-closure obligations, representing the fair value of legally restricted assets, totaling $28.7 million ($28.3 million as at December 31, 2023).

Notes

On June 17, 2024, GFL issued the 6.625% 2032 Notes. Concurrent with the issuance, GFL entered into a cross-currency interest rate swap for US$500.0 million to manage its currency risk. GFL used the net proceeds of the issuance to fund the redemption of the entire US$500.0 million outstanding aggregate principal amount, related fees, premiums and accrued interest on the 4.250% 2025 Secured Notes. GFL also terminated the cross-currency interest rate swap on the 4.250% 2025 Secured Notes and the 4.750% 2029 Notes. A loss on termination of hedged arrangements of $17.2 million and write off of deferred finance costs of $1.6 million were recognized in interest and other finance costs.

Revolving credit facility and term loan facility

Under the amended and restated revolving credit agreement dated as of June 4, 2024 (the “Revolving Credit Agreement”), GFL has access to a $1,205.0 million revolving credit facility (available in Canadian and US dollars) and an aggregate US$75.0 million in revolving credit facilities (available in US dollars) (collectively, the “Revolving Credit Facility”). The Revolving Credit Facility matures on September 27, 2026 and accrues interest at a rate of SOFR/CORRA plus 1.500% to 2.250% plus a credit spread adjustment or Canadian/US prime plus 0.500% to 1.250%. The Revolving Credit Facility is secured by mortgages on certain properties, a general security agreement over all of the assets of GFL and certain material subsidiaries and a pledge of the shares of such subsidiaries.

The Revolving Credit Agreement contains a Total Net Funded Debt to Adjusted EBITDA and an Interest Coverage Ratio (each as defined in the Revolving Credit Agreement) financial maintenance covenant.

The Total Net Funded Debt to Adjusted EBITDA ratio to be maintained is equal to or less than 6.00 to 1.00 for a period of four complete fiscal quarters following completion of a Material Acquisition and at all other times, equal to or less than 5.75 to 1.00. The Interest Coverage Ratio must be equal to or greater than 3.00 to 1.00. As at December 31, 2024 and December 31, 2023, GFL was in compliance with these covenants.

GFL has a term loan B facility (the “Term Loan B Facility”) that matures on July 3, 2031 with a borrowing rate of SOFR (with a floor rate at 0.500%) plus 2.000% or US prime plus 1.000%. The Term Loan B Facility is secured by mortgages on certain properties, a general security agreement over all the assets of GFL and certain material subsidiaries and a pledge of the shares of such subsidiaries.

Tax-exempt bonds

Industrial revenue bonds are tax-exempt municipal debt securities issued by a government agency on our behalf and sold only to qualified institutional buyers. On October 8, 2024, GFL participated in the issuance of US$210.0 million aggregate principal amount of Solid Waste Disposal Revenue Bonds issued by Florida Development Finance Corporation. The bonds bear interest at 4.375% payable semi-annually commencing on May 15, 2025 and have an initial mandatory tender date of October 1, 2031.

Acquisitions via business combinations includes $0.9 million of measurement period adjustments to adjust previously reported purchase price allocations completed during prior years.

As at December 31, 2024, GFL had income tax losses of approximately $362.0 million ($1,716.0 million as at December 31, 2023) available to carry forward to reduce future years’ taxable income. If not utilized, these losses will begin to expire in 2027 and fully expire in 2044.

In addition, one of the USA subsidiaries has income tax losses of $115.7 million, which are in a separate tax return and cannot be used by the rest of the GFL USA group.

GFL’s basis for recording deferred income tax assets is the availability of deferred income tax liabilities, which in certain taxable jurisdictions will offset these deferred income tax assets in the future. In other taxable jurisdictions, our basis for recording deferred income tax assets is forecasted taxable income for that jurisdiction, which GFL considers probable to occur.

GFL’s main lines of business are the transporting, managing, and recycling of solid and liquid waste and soil remediation services. GFL is divided into operating segments corresponding to the following lines of business: Solid Waste, which includes hauling, landfill, transfer and MRFs and Environmental Services, which includes liquid waste and soil remediation. Inter-segment transfers are made at market prices.

The operating segments are presented in accordance with the same criteria used for the internal report prepared for the chief operating decision-maker (“CODM”) who is responsible for allocating the resources and assessing the performance of the operating segments. The CODM assesses the performance of the segments on several factors, including gross revenue, intercompany revenue, revenue and adjusted EBITDA. GFL’s CODM is the Chief Executive Officer.

The Solid Waste segment follows a national internal reporting structure, and each country is considered a separate operating segment by the CODM.

The following tables present GFL’s revenue and Adjusted EBITDA by operating segment for the periods indicated. Gross revenue is calculated based on revenue before intercompany revenue eliminations.

SHAREHOLDER'S CAPITAL

SHAREHOLDER'S CAPITAL

17. SHAREHOLDERS’ CAPITAL

Authorized capital

GFL’s authorized share capital consists of (i) an unlimited number of subordinate voting shares, (ii) an unlimited number of multiple voting shares (“MVS”), (iii) an unlimited number of preferred shares, issuable in series, (iv) 28,571,428 Series A perpetual convertible preferred shares (the “Series A Preferred Shares”) and (v) 8,196,721 Series B perpetual convertible preferred shares (the “Series B Preferred Shares”). The Series A Preferred Shares and Series B Preferred Shares are collectively referred to as the “Preferred Shares”.

Subordinate and multiple voting shares

The rights of the holders of the subordinate voting shares and the multiple voting shares are substantially identical, except for voting and conversion. The holders of outstanding subordinate voting shares are entitled to one vote per subordinate voting share and the holders of multiple voting shares are entitled to ten votes per multiple voting share. The subordinate voting shares are not convertible into any other classes of shares. Each outstanding multiple voting share may at any time, at the option of the holder, be converted into one subordinate voting share. All multiple voting shares are owned by entities controlled by Patrick Dovigi.

In addition, all multiple voting shares will convert automatically into subordinate voting shares at such time that is the earlier of the following: (i) Patrick Dovigi and/or his affiliates no longer beneficially own, directly or indirectly, at least 2.0% of the aggregate of the issued and outstanding subordinate voting shares and multiple voting shares; (ii) Patrick Dovigi is no longer serving as a director or in a senior management position at GFL; or (iii) the twentieth anniversary of the closing of the IPO.

The subordinate voting shares and multiple voting shares rank pari passu with respect to the payment of dividends, return of capital and distribution of assets in the event of liquidation, dissolution or winding up of GFL.

Preferred shares

The preferred shares are issuable at any time and from time to time in series. Each series of preferred shares shall consist of such number of preferred shares and having such rights, privileges, restrictions and conditions as determined by the Board of Directors prior to the issuance thereof.

As at December 31, 2024, (a) the Series A Preferred Shares are convertible into 11,654,115 subordinate voting shares, at a conversion price of US$25.17, representing 2.9% of the issued and outstanding subordinate voting shares and 2.2% of the aggregate outstanding voting rights, and (b) the Series B Preferred Shares are convertible into 8,193,894 subordinate voting shares, at a conversion price of US$43.88, representing 2.0% of the issued and outstanding subordinate voting shares and 1.6% of the aggregate outstanding voting rights. The holders of the Preferred Shares are entitled to vote on an as-converted basis on all matters on which holders of subordinate voting shares and multiple voting shares vote, and to the greatest extent possible, will vote with the holders of subordinate voting shares and multiple voting shares as a single class. Each holder of Preferred Shares shall be deemed to hold, for the sole purpose of voting at any meeting of shareholders of GFL at which such holder is entitled to vote, the number of Preferred Shares equal to the number of subordinate voting shares into which such holder’s registered Preferred Shares are convertible as of the record date for the determination of shareholders entitled to vote at such shareholders meeting. The liquidation preference of the Series A Preferred Shares and Series B Preferred Shares accrete at a rate of 7.000% and 6.000% per annum, respectively, compounded quarterly. From and after December 31, 2024 (in the case of the Series A Preferred Shares) or December 31, 2025 (in the case of the Series B Preferred Shares), GFL will have the option each quarter to redeem a number of Preferred Shares in an amount equal to the increase in the liquidation preference for the quarter. This optional redemption amount can be satisfied in either cash or subordinate voting shares at the election of GFL. If GFL elects to pay the optional redemption amount for a particular quarter in cash, the accretion rate for that quarter for the Series A Preferred Shares and Series B Preferred Shares will be 6.000% and 5.000% per annum, respectively. The Preferred Shares are subject to transfer restrictions, but can be converted into subordinate voting shares by the holder at any time. GFL may also require the conversion or redemption of the Preferred Shares at an earlier date in certain circumstances.

Normal course issuer bid

On May 10, 2023, the Toronto Stock Exchange accepted GFL’s notice of intention to renew its normal course issuer bid (“NCIB”) during the twelve-month period commencing on May 12, 2023 and ending May 11, 2024. Under the NCIB, a maximum of 17,867,120 subordinate voting shares were available to be repurchased by GFL. During the years ended December 31, 2024 and December 31, 2023, GFL did not repurchase any subordinate voting shares under the NCIB. GFL did not renew the NCIB on its expiration.

Share issuances and cancellations

The following table presents GFL’s share capital for the periods indicated:

On March 5, 2024, 3,604,014 Series A Preferred Shares were converted into 3,813,579 subordinate voting shares at the conversion price of US$25.18. On September 12, 2024, 14,565,543 Series A Preferred Shares were converted into 16,000,000 subordinate voting shares at the conversion price of US$25.18.

Share options, RSUs, DSUs and PSUs

The Board of Directors adopted the LTIP which allows GFL to grant long-term equity-based incentives, including options, PSUs and RSUs, to eligible participants. Each award represents the right to receive subordinate voting shares, or in the case of PSUs and RSUs, subordinate voting shares and/or cash, in accordance with the terms of the LTIP. The director deferred share unit plan (the “DSU Plan”) was adopted by the Board of Directors, to provide non-employee directors the opportunity to receive a portion of their compensation in the form of DSUs. Each DSU represents a unit equivalent in value to a subordinate voting share based on the closing price of the subordinate voting shares on the day prior to the grant.

The maximum number of subordinate voting shares reserved for issuance under the LTIP, the DSU Plan, and any other security-based compensation arrangement in any one-year period is 10% of the total issued and outstanding subordinate voting shares and multiple voting shares in the capital which as at December 31, 2024, would equate to 39,338,342 subordinate voting shares in the capital of GFL.

GFL’s financial instruments consist of cash, trade accounts receivable, trade accounts payable and long-term debt, including related hedging instruments.

Fair value measurement

The carrying value of GFL’s financial assets approximate their fair values. The carrying value of GFL’s financial liabilities approximate their fair values with the exception of GFL’s outstanding U.S. dollar secured and unsecured notes (the “Notes”) and 4.375% Bonds. The fair value hierarchy for these instruments are as follows for the periods indicated:

Notes	$	7,337.4	$	7,087.5	$	—	$	7,087.5	$	—

GFL uses a discounted cash flow model incorporating observable market data, such as foreign currency forward rates, to estimate the fair value of its Notes. Certain leases, other loans and amounts due to related parties do not bear interest or bear interest at an amount that is not stated at fair value.

Net derivative instruments are recorded at fair value and classified within Level 2.

Financial risk management objectives

As a result of holding and issuing financial instruments, GFL is exposed to liquidity, credit and market risks. The following provides a description of these risks and how GFL manages these exposures.

Credit risk

Credit risk is the risk of loss associated with a counterparty’s inability to fulfill its payment obligations. GFL’s principal financial assets that expose it to credit risk are accounts receivable.

GFL uses historical trends of default, the timing of recoveries and the amount of loss incurred, adjusted for management’s judgement as to whether current economic and credit conditions are such that the actual losses are likely to be greater or less than suggested by historical trends. GFL considers the following as constituting an event of default for internal credit risk management purposes as historical experience indicates that accounts receivable that meet either of the following criteria are generally not recoverable:

●

the customer is insolvent; or

●

GFL’s relationship with the customer has been severed; and/or

●

the customer’s receivable has aged beyond a reasonable period.

GFL provides credit to its customers in the normal course of its operations. The amounts disclosed in the statement of financial position represent the maximum credit risk and are net of allowance for doubtful accounts, based on management’s estimates taking into account GFL’s prior experience and its assessment of the current economic environment.

The following is a breakdown of the trade receivables aging. It does not include holdbacks or unbilled revenue as they are made up of amounts to be received at the end of specific long term contracts.


	December 31, 2024		December 31, 2023
0-60 days	$	846.8	$	787.8
61-90 days		111.3		103.7
91+ days		136.4		127.6
	$	1,094.5	$	1,019.1

In determining the recoverability of trade and other receivables, GFL considers any change in the credit quality of the trade receivable from the date credit was initially granted up to the end of the reporting period.

Liquidity risk

GFL monitors and manages its liquidity to ensure that it has access to sufficient funds to meet its liabilities when due. Management of GFL believes that future cash flows from operations and the availability of credit under existing bank arrangements is adequate to support GFL’s financial liquidity needs for its ongoing operations.

GFL has financial liabilities with varying contractual maturity dates. With the exception of long-term debt and lease obligations, all of GFL’s significant financial liabilities mature in less than one year.

Interest rate risk

Interest rate risk is the risk that the fair value or future cash flows of a financial liability will fluctuate because of changes in market interest rates. GFL enters into both fixed and floating rate debt and also leases certain assets with fixed rates.

GFL’s risk management objective is to minimize the potential for changes in interest rates to cause adverse changes in cash flows to GFL. The ratio of fixed to floating rate obligations outstanding is designed to maintain flexibility in GFL’s capital structure to adjust to prevailing market conditions. GFL also manages interest rate risk through hedging instruments, as discussed further below as part of foreign currency risk.

At December 31, 2024, GFL had a ratio of fixed to floating rate obligations of approximately 83.2% fixed and 16.8% floating (86.5% fixed and 13.5% floating as at December 31, 2023).

A 1% change in the interest rate on floating rate obligations would have resulted in a change in the interest expense for the year ended December 31, 2024 of approximately $16.6 million based on the balances outstanding as at December 31, 2024 (approximately $5.7 million for the year ended December 31, 2023).

Foreign currency risk

GFL is exposed to foreign currency risk relating to its operating and financing activities and partially mitigates such risk using certain cross-currency interest rate swaps. A $0.01 change in the U.S. dollar to Canadian dollar exchange rate would impact our annual revenue and income for year ended December 31, 2024, by approximately $34.5 million and $10.8 million, respectively ($33.9 million and $10.2 million respectively, for the year ended December 31, 2023).

GFL’s swapped instruments included the following:


	Notional					Fixed Foreign
	Amount	Fixed/Variable		Fixed/Variable Interest		Exchange
Underlying Items	($US)	Interest Rate Paid		Rate Received		Rate Paid	Effective Date	Expiration
5.125% 2026 Secured Notes	500.0	5.725	%	5.125	%	1.3245	December 16, 2019	December 15, 2026
8.500% 2027 Notes	48.0	8.399	%	8.500	%	1.3355	April 23, 2019	May 1, 2027
8.500% 2027 Notes	300.0	8.419	%	8.500	%	1.3355	April 23, 2019	May 1, 2027
8.500% 2027 Notes	348.0	8.500	%	8.828	%	1.2026	June 8, 2021	May 1, 2027
4.000% 2028 Notes	500.0	4.524	%	4.000	%	1.3112	November 23, 2020	August 1, 2028
6.625% 2032 Notes	500.0	6.101	%	6.625	%	1.3652	June 17, 2024	April 1, 2032

The effective cross-currency swaps eliminate the impact of changes in the value of the U.S. dollar between the date of issuance of the Notes and their respective maturity dates.

The cross-currency interest rate swap associated with the 8.500% 2027 Notes continued to be in place after the redemption of the notes. As a result of the redemption, GFL discontinued the use of hedge accounting. GFL entered into an offset swap to receive and pay interest semi-annually at 8.828% on US$348.0 million in order to hedge this exposure.

These cross-currency swaps have been designated at inception and accounted for as cash flow hedges. A loss, net of tax, in the fair value of derivatives designated as cash flow hedges in the amount of $44.8 million has been recorded in other comprehensive loss for the year ended December 31, 2024 ($28.5 million gain, net of tax for the year ended December 31, 2023).

Commodity risk

GFL markets a variety of recyclable materials, including cardboard, mixed paper, plastic containers, glass bottles and ferrous and aluminum metals. GFL owns and operates recycling operations and sells other collected recyclable materials to third parties for processing before resale. To reduce GFL’s exposure to commodity price risk with respect to recycled materials, it has adopted a pricing strategy of charging collection and processing fees for recycling volume collected from third parties. In the event of a change in recycled commodity prices, a 10% change in average recycled commodity prices from the average prices that were in effect would have had a $17.9 million and $10.7 million impact on revenues for the year ended December 31, 2024 and December 31, 2023, respectively.

Capital management

GFL defines capital that it manages as the aggregate of its shareholders’ equity and long-term debt net of cash.

GFL makes adjustments to its capital based on the funds available to GFL in order to support the ongoing operations of the business and in order to ensure that the entities in GFL will be able to continue as going concerns, while maximizing the return to stakeholders through the optimization of the debt and equity balances.

GFL manages its capital structure, and makes adjustments to it in light of changes in economic conditions. In order to maintain or modify the capital structure, GFL may arrange new debt with existing or new lenders, or obtain additional financing through other means.

Management reviews its capital management approach on an ongoing basis and believes that this approach, given the size of GFL, is reasonable. There were no changes in GFL’s approach to capital management during the year ended December 31, 2024, and year ended December 31, 2023.

Dec. 31, 2024

SUMMARY OF MATERIAL ACCOUNTING POLICIES

Accounting policy for Basis of presentation

Basis of presentation

These Annual Financial Statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”), as issued by the International Accounting Standards Board (“IASB”).

Accounting policy for Basis of measurement

Basis of measurement

These Annual Financial Statements were prepared on the historical cost basis except for certain financial instruments that are measured at fair value at the end of the reporting period (see Note 19).

Accounting policy for Presentation and functional currency

Presentation and functional currency

These Annual Financial Statements are presented in Canadian dollars which is GFL’s functional currency.

Accounting policy for Basis of consolidation

Basis of consolidation

Subsidiaries are entities controlled by GFL. Control exists when GFL has power over an entity, exposure or rights to variable returns from GFL’s involvement with the entity, and the ability to use its power over the entity to affect the amount of GFL’s returns. The financial accounts and results of subsidiaries are included in these Annual Financial Statements of GFL from the date that control commences until the date that control ceases.

When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with GFL’s accounting policies. All intercompany assets and liabilities, equity, income, expenses and cash flows relating to transactions between GFL and its subsidiaries are eliminated in full on consolidation.

Accounting policy for Business combinations

Business combinations

Acquisitions of subsidiaries and businesses are accounted for using the acquisition method with the results of operations consolidated with those of GFL from the date of acquisition. The consideration for each acquisition is measured as the aggregate of the fair values of assets given, liabilities incurred or assumed and the equity instruments issued by GFL in exchange for control of the acquired company or business. Acquisition-related costs are recognized in the consolidated statement of operations as incurred.

GFL’s growth strategy is to focus on generating organic growth from all of its operating segments. In addition to organic growth, GFL deploys an active acquisition strategy involving the integration of acquired businesses into each of its operating segments through integration of property and equipment, back office functions, improving route density and realignment of disposal alternatives to effect synergies and maximize profits. Goodwill arising from acquisitions is largely attributable to the assembled workforce of the acquisitions, the potential synergies with the acquiree, and intangible assets that do not qualify for separate recognition.

The determination of the fair values of acquired intangible assets and acquired landfill assets requires GFL to make significant estimates and assumptions. The significant assumptions used to value acquired intangible assets and acquired landfill assets include, among others, future expected cash flows and discount rate.

Accounting policy for Equity accounting for joint arrangements and associates

Equity accounting for joint arrangements and associates

Associates are all entities over which GFL has significant influence but not control or joint control. Investments in associates are accounted for using the equity method of accounting after initially being recognized at cost.

Joint arrangements are classified as either joint operations or joint ventures. The classification depends on contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. Interests in joint ventures are accounted for by GFL using the equity method, after initially being recognized at cost.

An investment is considered to be impaired if there are objective evidences of impairments, as a result of one or more events that occurred after the initial recognition, and those events have negative impacts on the future cash flows of the investment that can be reliably estimated. The investment is reviewed at each balance sheet date to determine whether there is any indication of impairment.

Accounting policy for Property and equipment

Property and equipment

Property and equipment are stated at cost, less accumulated depreciation and impairment. Assets are depreciated to residual values over their estimated useful lives, with depreciation commencing when an asset is ready for use. Significant parts of property and equipment that have different depreciable lives are depreciated separately. Judgment is used in determining the appropriate level of componentization.

Depreciation is computed on a straight-line basis, unless otherwise stated, using the following useful lives:


Type of property and equipment		Depreciation term
Buildings and improvements		10 to 30 years or term of lease
Landfills		Units of production
Vehicles		10 to 20 years
Machinery and equipment		3 to 20 years
Containers		5 to 10 years
Right-of-use assets		Shorter of lease term or life of underlying asset(s)

The costs of repair and maintenance activities are recognized in the consolidated statement of operations as incurred. Distinguishing major inspections and overhaul from repairs and maintenance in determining which costs are capitalized is a matter of management judgement.

An item of property and equipment is de-recognized upon disposal or when no future economic benefits are expected to arise from the continued use of the asset. Any gain or loss arising on de-recognition of the asset (calculated as the difference between net disposal proceeds and the carrying amount of the asset) is included as a gain or loss in the consolidated statement of operations in the period the asset is de-recognized.

Property and equipment are reviewed at the end of each reporting period to determine whether there is any indication of impairment. If the possibility of impairment is indicated, GFL will estimate the recoverable amount of the asset and record any impairment loss in the consolidated statement of operations.

Assets under development are not depreciated until they are available for use.

Accounting policy for Landfill assets

Landfill assets

Landfill assets represent the cost of landfill airspace, including original acquisition cost and landfill construction and development costs, incurred during the operating life of the site. Landfill assets also include capitalized landfill closure and post-closure costs, net of accumulated amortization, and the cost of either new or landfill expansion permits.

The original cost of landfill assets, together with incurred and projected landfill construction and development costs, is amortized on a per unit basis as landfill airspace is consumed.

Landfill assets are amortized over their total available disposal capacity representing the sum of estimated permitted airspace capacity (having received the final permit from the governing authorities) plus future permitted airspace capacity, representing an estimate of airspace capacity that management believes is probable of being permitted based on the following criteria:

●

Personnel are actively working to obtain the permit or permit modifications necessary for expansion of an existinglandfill, and progress is being made on the project;

●

It is probable that the required approvals will be received within the normal application and processing periods for approvals in the jurisdiction in which the landfill is located;

●

GFL has a legal right to use or obtain land associated with the expansion plan;

●

There are no significant known political, technical, legal or business restrictions or issues that could impair the success of the expansion effort;

●

Management is committed to pursuing the expansion; and

●

Additional airspace capacity and related costs have been estimated based on the conceptual design of the proposed expansion.

GFL has been successful in receiving approvals for expansions pursued; however, there can be no assurance that GFL will be successful in obtaining approvals for landfill expansions in the future.

Accounting policy for Intangible assets

Intangible assets

Intangible assets are stated at cost, less accumulated amortization and impairment, and consist of customer lists, municipal and other commercial contracts, trade name, licenses and permits, non-compete agreements and Certificates of Approvals or Environmental Compliance Approvals (“C of As”). C of As provide GFL with certain waste management rights in the province or state of issuance. C of As that do not expire are considered to have an indefinite life and therefore are not subject to amortization. C of As that relate to a leased facility are amortized over the lease term.

Amortization is based on the estimated useful life using the following methods and rates:


Type of intangible asset		Amortization term
Indefinite life C of As		Indefinite
Customer lists and municipal contracts	Straight-line	5 to 10 years
Trade name, definite life C of As and other assets	Straight-line	1 to 15 years
Non-compete agreements	Straight-line	5 years

Intangible assets with indefinite useful lives are tested at least annually, at the cash-generating unit (“CGU”) level for impairment. The assessment of indefinite life is reviewed annually to determine whether the indefinite life assessment continues to be supportable. If not, the change in the useful life assessment from indefinite to finite is made on a prospective basis. Intangible assets with finite lives are amortized over the useful economic life on a straight-line basis and assessed for impairment whenever there is an indication that the intangible asset may be impaired. Amortization expense is included as part of cost of sales.

Accounting policy for Goodwill

Goodwill

Goodwill arising on an acquisition of a business represents the excess of the purchase price over the fair value of the net identifiable assets of the acquired business. Goodwill is carried at cost as established at the date of acquisition of the business less accumulated impairment losses, if any.

For the purpose of impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to CGUs based on the lowest level within the entity in which the goodwill is monitored for internal management purposes. The allocation is made to those CGUs that are expected to benefit from the business combination in which the goodwill arose. GFL tests its goodwill for impairment at the operating segment level. Any potential impairment of goodwill is identified by comparing the recoverable amount of a CGU to its carrying value. Goodwill is reduced by the amount of deficiency, if any. If the deficiency exceeds the carrying amount of goodwill, the carrying values of the remaining assets in the CGUs are reduced by the excess on a pro-rata basis. GFL tests goodwill for impairment annually or more frequently if there are indications of impairment.

The recoverable amount of a CGU is the higher of the estimated fair value less costs of disposal or value-in-use of the CGU. In assessing value-in-use, the estimated future cash flows are discounted using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the CGU.

Accounting policy for Landfill closure and post-closure obligations

Landfill closure and post-closure obligations

GFL recognizes the estimated liability for an asset retirement obligation (“ARO”) that results from acquisition, construction, development or normal operations in the year in which it is incurred. Costs associated with capping, closing and monitoring a landfill or portions of a landfill, after it ceases to accept waste, are initially measured at the discounted future value of the estimated cash flows over the landfill’s operating life. The operating life represents the period over which the landfill receives waste. This value is capitalized as part of the cost of the related asset and amortized over the asset’s useful life.

The determination of the obligations requires GFL to make significant estimates and assumptions. The significant assumptions include the estimates of future expenditures of landfill capping, closure and post-closure activities, which are prepared by internal and third-party engineering specialists and reviewed at least once annually and consider, amongst other things, regulations that govern each site. The estimated liabilities are valued using present value techniques that consider and incorporate assumptions and considerations marketplace participants would use in the determination of those estimates, including inflation, markups, inherent uncertainties due to the timing of work performed, information obtained from third parties, quoted and actual prices paid for similar work and engineering estimates. Inflation assumptions are based on management’s evaluation of current and future economic conditions and the expected timing of these expenditures. Estimates are discounted applying the risk-free rate, which is a rate that is essentially free of default risk. In determining the risk-free rate, consideration is given to both current and future economic conditions and the expected timing of expenditures.

Accounting policy for Revenue recognition

Revenue recognition

GFL records revenue when control is transferred to the customer which is the time that the service is provided. Revenue is measured based on the consideration specified in a contract with a customer or consideration agreed by a customer. Revenue excludes amounts collected on behalf of third parties. GFL recognizes revenue from the following major sources:

Collection and disposal of solid waste

GFL generates revenue through fees charged for the collection of solid waste including recyclables, from its municipal, residential and commercial and industrial customers. Revenues from these contracts are influenced by a variety of factors including collection frequency, type of service, type and volume or weight of waste and type of equipment and containers furnished to the customer.

Our municipal customer relationships are generally supported by contracts ranging from three to ten years. Our municipal collection contracts provide for fees based upon a per household, per tonne or ton, per lift or per service basis and often provide for annual price increases indexed to the Consumer Price Index (“CPI”), other waste related indices and market costs for fuel. We provide regularly scheduled service to a large percentage of our commercial and industrial customers under contracts with three to five year terms with automatic renewals, volume-based pricing and CPI, fuel and other adjustments. Other commercial and industrial customers are serviced on an “on-call” basis, for which revenue is recognized when the service has been provided.

Certain future variable considerations of long-term customer contracts may be unknown upon entering into the contract, including the amount that will be billed in accordance with annual CPI, market costs for fuel and commodity prices. The amount to be billed is often tied to changes in an underlying base index such as a CPI or a fuel or commodity index, and revenue is recognized once the index is established for the future period. GFL does not disclose the value of unsatisfied performance obligations for these contracts as its right to consideration corresponds directly to the value provided to the customer for services completed to date and all future variable consideration is allocated to wholly unsatisfied performance obligations.

In addition to handling GFL’s own collected waste volumes, its transfer stations, material recovery facilities (“MRFs”), landfills and organic waste processing facilities generate revenue from tipping fees paid to GFL by municipalities and third-party haulers and waste generators, processing fees, and the sale of recycled commodities. GFL also operates MRFs, transfer stations and landfills for municipal owners under a variety of compensation arrangements, including fixed fee arrangements or on a tonnage or other basis. Revenue is recognized at the time service is provided.

Collection and disposal of liquid waste

GFL generates revenue through fees charged for the collection, management, transportation, processing and disposal of a wide variety of industrial and commercial liquid wastes. Revenue is primarily derived from fees charged to customers on a per service, volume and/or hour basis. Revenues from these contracts are influenced by a variety of factors including timing of contract, type of service, type and volume of liquid waste and type of equipment used. Revenue in the liquid waste business is also derived from the stewardship return incentives paid by most Canadian provinces in which GFL has liquid waste operations, as well as from the sale of used motor oil, solvents and downstream products to third parties. The fees received from third parties are based on the market, type and volume of material sold. Revenue is recognized at the time when service is provided. Revenue recognized under these agreements is variable in nature based on volumes and commodity prices at the time of sale, which are unknown at contract inception.

Accounting policy for Share based payments

Share-based payments

Share options issued by GFL as remuneration of its key employees, officers, and directors are settled in subordinate voting shares and are accounted for as equity-settled awards.

The fair value of options granted is measured using either the Black-Scholes option pricing model or the Monte Carlo simulation methods, which rely on estimates of the expected risk-free interest rate, expected dividend payments, expected share price volatility, the value of GFL’s shares and the expected average life of the options. GFL believes these models adequately capture the substantive features of the option awards and are appropriate to calculate their fair values.

The fair value of the options determined at the grant date is expensed over the vesting period using an accelerated method of amortization, with a corresponding increase to contributed surplus. Expense related to share-based payments is included as part of selling, general and administrative expense. Upon exercise of options, the amount recognized in contributed surplus for the awards and the cash received upon exercise are recognized as an increase in share capital.

GFL has a long-term incentive plan (“LTIP”) to grant long-term equity-based incentives, including options, performance share units (“PSUs”), restricted share units (“RSUs”), and deferred share units (“DSUs”) to eligible participants. Each award represents the right to receive subordinate voting shares, or in the case of PSUs and RSUs, subordinate voting shares and/or cash, in accordance with the terms of the LTIP.

The fair value of the RSUs and DSUs granted are based on the closing price of the subordinate voting shares on the day prior to the grant. The fair value of the RSUs and DSUs are recognized as compensation expense over the vesting period.

Accounting policy for Income taxes

Income taxes

Income tax expense or recovery is comprised of current and deferred income taxes. It is recognized in the consolidated statement of operations, except to the extent that the expense relates to items recognized directly in equity.

A current or non-current tax liability/asset is the estimated tax payable/receivable on taxable income for the period, and any adjustments to taxes payable with respect to previous periods.

The liability method is used to account for deferred tax assets and liabilities, which arise from temporary differences between the carrying amount of assets and liabilities recognized in the consolidated statement of financial position and their corresponding tax basis. The carry forward of unused tax losses and credits are recognized to the extent that it is probable they can be used in the future.

The carrying amount of deferred income tax assets is reviewed at each reporting date and reduced to the extent it is no longer probable that the deferred income tax asset will be recovered.

Deferred income tax assets and liabilities are calculated at the tax rates that are expected to apply when the asset or liability is recovered or settled. Current and deferred tax assets and liabilities are calculated using tax rates that have been enacted or substantively enacted at the end of the reporting date.

Where current tax or deferred tax arises from the initial accounting for a business combination, the tax effect is included in the accounting for the business combination.

Deferred tax income liabilities are offset if a legally enforceable right exists to set off current income tax assets against current income tax liabilities and the deferred tax relates to the same taxable entity and the same taxation authority.

Accounting policy for Financial instruments

Financial instruments

Classification and measurement

All financial assets and liabilities are recognized initially at fair value plus or minus transaction costs, except for financial instruments at fair value through profit or loss (“FVTPL”), for which transaction costs are expensed.

Debt financial instruments are subsequently measured at FVTPL, fair value through other comprehensive income (“FVTOCI”), or amortized cost using the effective interest rate method. GFL determines the classification of its financial assets based on GFL’s business model for managing the financial assets and whether the instruments’ contractual cash flows represent solely payments of principal and interest on the principal amount outstanding.

GFL’s derivatives designated as a hedging instrument in a qualifying hedge relationship are subsequently measured at FVTOCI. Equity instruments that meet the definition of a financial asset, if any, are subsequently measured at FVTPL or elected irrevocably to be classified at FVTOCI at initial recognition. Derivatives not designated in a qualified hedge relationship are measured at FVTPL.

Financial liabilities are subsequently measured at amortized cost using the effective interest method or at FVTPL in certain circumstances or when the financial liability is designated as such. For financial liabilities that are designated as FVTPL, the amount of change in the fair value of the financial liability that is attributable to changes in GFL’s own credit risk of that liability is recognized in other comprehensive income or loss unless the recognition of the effects of changes in the liability’s credit risk in other comprehensive income or loss would create or enlarge an accounting mismatch in the consolidated statement of operations. The remaining amount of change in the fair value of the liability is recognized in the consolidated statement of operations. Changes in the fair value of a financial liability attributable to GFL’s own credit risk, if any, are recognized in other comprehensive income or loss and are not subsequently reclassified to the consolidated statement of operations; instead, they are transferred to retained earnings, upon de-recognition of the financial liability.

All of GFL’s financial assets are categorized within the amortized cost measurement category. All of GFL’s financial liabilities, with the exception of deferred foreign exchange derivatives and the Purchase Contracts (as defined below), are also categorized within the amortized cost measurement category. Deferred foreign exchange derivatives, which qualify for hedge accounting, are categorized within the FVTOCI category and the Purchase Contracts, which is a financial liability with embedded derivative features, is categorized within the FVTPL category.

Impairment

GFL uses a forward-looking Expected Credit Loss (“ECL”) model to determine impairment of financial assets. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that GFL expects to receive.

For trade receivables, GFL applies the simplified approach and has determined the allowance based on lifetime ECLs at each reporting date. GFL establishes a provision that is based on GFL’s historical credit loss experience, adjusted for forward-looking factors specific to the customers and the economic environment.

Hedge accounting

GFL is exposed to the risk of currency fluctuations and has entered into currency derivative contracts and is exposed to the risk of fuel price fluctuations and has entered into fuel derivative contracts to hedge a portion of this exposure on the basis of planned transactions. Where hedge accounting is applied, the criteria are documented at the inception of the hedge and updated at each reporting date. GFL documents the relationship between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking the hedging transactions. GFL also documents its assessment, at hedge inception and on an ongoing basis, of whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items.

Accounting policy for Basis of fair values

Basis of fair values

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

●

In the principal market for the asset or liability, or

●

In the absence of a principal market, in the most advantageous market for the asset or liability.

GFL uses valuation techniques that it believes are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. All assets and liabilities for which fair value is measured or disclosed are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

Level 1 — quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 — inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3 — are unobservable inputs for the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date.

Accounting policy for Critical accounting judgments and estimates

Critical accounting judgments and estimates

The preparation of the Annual Financial Statements in conformity with IFRS requires management to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities, revenue and expense for the period. Such estimates relate to unsettled transactions and events as of the date of the Annual Financial Statements. Accordingly, actual results may differ from estimated amounts as transactions are settled in the future. Estimates and assumptions are reviewed on an ongoing basis. Revisions to estimates are applied prospectively.

The following areas are the critical judgments and estimates that management has made in applying GFL’s accounting policies and that have the most significant effect on amounts recognized in the Annual Financial Statements:

●

Determining the fair value of acquired assets and liabilities in business combinations, specifically the fair value of acquired intangible assets and acquired landfill assets

●

Estimating the amount and timing of the landfill closure and post-closure obligations, specifically the estimated future expenditures associated with landfill capping, closure and post-closure activities

●

Determining the key assumptions for impairment testing for long-lived assets

Accounting policy for Foreign currency translation

Foreign currency translation

Functional currency

Items related to GFL’s subsidiaries are measured using the currency of the primary economic environment in which each entity operates (the functional currency). Foreign currency transactions are translated into the functional currency of each entity using the exchange rates prevailing at the date of the transactions or valuation when items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions and from the remeasurement at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognized in the consolidated statement of operations.

Foreign operations

GFL’s foreign operations are conducted through its subsidiaries located in the United States of America (“US subsidiaries”), whose functional currency is the United States dollar.

The assets and liabilities of these US subsidiaries are translated into the presentation currency of GFL using the exchange rate at the reporting date. Revenues and expenses are translated at the average exchange rate for the period. The resulting foreign exchange translation differences are recorded as a currency translation adjustment in other comprehensive income or loss.

Accounting policy for New and amended standards adopted

New and amended standards adopted

A number of amended standards became applicable for the current reporting period. GFL was not required to change its accounting policies or make retrospective adjustments as a result of adopting the applicable amended standards.

Accounting policy for New accounting standards issued but not yet effective

New accounting standards issued but not yet effective

Certain new accounting standards and interpretations have been published that are not mandatory for the current period and have not been early adopted. For those standards and interpretations applicable to GFL, they are not expected to have a material impact on the Annual Financial Statements in future periods.

The amount of liabilities that are: (a) a contractual obligation: (i) to deliver cash or another financial asset to another entity; or (ii) to exchange financial assets or financial liabilities with another entity under conditions that are potentially unfavourable to the entity; or (b) a contract that will, or may be, settled in the entity’s own equity instruments and is: (i) a non-derivative for which the entity is, or may be, obliged to deliver a variable number of the entity’s own equity instruments; or (ii) a derivative that will, or may be, settled other than by the exchange of a fixed amount of cash or another financial asset for a fixed number of the entity’s own equity instruments. For this purpose, rights, options or warrants to acquire a fixed number of the entity’s own equity instruments for a fixed amount of any currency are equity instruments if the entity offers the rights, options or warrants pro rata to all of its existing owners of the same class of its own non-derivative equity instruments. Also, for those purposes the entity’s own equity instruments do not include puttable financial instruments that are classified as equity instruments in accordance with paragraphs 16A-16B of IAS 32, instruments that impose on the entity an obligation to deliver to another party a pro rata share of the net assets of the entity only on liquidation and are classified as equity instruments in accordance with paragraphs 16C-16D of IAS 32, or instruments that are contracts for the future receipt or delivery of the entity’s own equity instruments. As an exception, an instrument that meets the definition of a financial liability is classified as an equity instrument if it has all the features and meets the conditions in paragraphs 16A-16B or paragraphs 16C-16D of IAS 32.
