Statement [line items]
Significant accounting policies	2. Significant accounting policies (a) Statement of compliance These condensed consolidated interim financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) under International Accounting Standard (IAS) 34 – Interim Financial Reporting. Except as described below, these financial statements were prepared using the same basis of presentation, accounting policies and methods of computation as outlined in Note 2, Significant accounting policies in the Company’s consolidated financial statements for the year ended October 31, 2021. These financial statements do not include all the notes required in annual financial statements. These condensed consolidated interim financial statements were approved and authorized for issue by the Board of Directors on June 13, 2022. (b) Basis of consolidation These condensed consolidated interim financial statements include the accounts of the Company and its subsidiaries. The Company’s eleven subsidiaries are entities controlled by the Company. Control exists when the Company has power over an investee, when the Company is exposed, or has rights, to variable returns from the investee and when the Company has the ability to affect those returns through its power over the investee. The subsidiaries are included in the condensed consolidated interim financial results of the Company from the effective date of incorporation up to the effective date of disposition or loss of control. The Company’s principal subsidiaries and their geographic location as at April 30, 2022 are set forth in the table below: Company Location Ownership interest Li-Cycle Ontario, Canada 100% Li-Cycle Ontario, Canada 100% Li-Cycle Delaware, U.S. 100% Li-Cycle Delaware, U.S. 100% Li-Cycle Delaware, U.S. 100% Li-Cycle Switzerland 100% Li-Cycle Singapore 100% Li-Cycle Germany 100% Li-Cycle Norway 67% Intercompany transactions, balances and unrealized gains/losses on transactions between the Company and its subsidiaries are eliminated. (c) Basis of preparation These condensed consolidated interim financial statements are presented in U.S. dollars, which is the Company’s functional currency. (d) New and revised IFRS Standards issued but not yet effective At the date of authorization of these financial statements, the Company has not applied the following new and revised IFRS Standards that have been issued but are not yet effective. Amendments to IFRS 3 Reference to the Conceptual Framework IFRS 17 (including the June 2020 amendments to IFRS 17) Insurance Contracts Annual Improvements to IFRS Standards 2018-2020 Amendments to IFRS 1 First-time Adoption of International Financial Reporting Standards, IFRS 9 Financial Instruments, IFRS 16 Leases, and IAS 41 Agriculture Amendments to IAS 1 Disclosure of Accounting Policies Amendments to IAS 1 Classifying liabilities as current or non-current Amendments to IAS 8 Definition of Accounting Estimates Amendments to IAS 12 Deferred Tax related to Assets and Liabilities arising from a Single Transaction Amendments to IAS 16 Property, Plant and Equipment—Proceeds before Intended Use Amendments to IAS 37 Onerous Contracts—Cost of Fulfilling a Contract The adoption of the IFRS Standards listed above are not expected to have a material impact on the financial statements of the Company in future periods, except as noted below. Amendments to IAS 1 Presentation of Financial Statements and IFRS Practice Statement 2 Making Materiality Judgements—Disclosure of Accounting Policies The amendments change the requirements in IAS 1 with regard to disclosure of accounting policies. The amendments replace all instances of the term ‘significant accounting policies’ with ‘material accounting policy information’. Accounting policy information is material if, when considered together with other information included in an entity’s financial statements, it can reasonably be expected to influence decisions that the primary users of general purpose financial statements make on the basis of those financial statements. The supporting paragraphs in IAS 1 are also amended to clarify that accounting policy information that relates to immaterial transactions, other events or conditions is immaterial and need not be disclosed. Accounting policy information may be material because of the nature of the related transactions, other events or conditions, even if the amounts are immaterial. However, not all accounting policy information relating to material transactions, other events or conditions is itself material. The International Accounting Standards Board has also developed guidance and examples to explain and demonstrate the application of the ‘four-step materiality process’ described in IFRS Practice Statement 2. The amendments to IAS 1 are effective for annual periods beginning on or after 1 January 2023, with earlier application permitted and are applied prospectively. The Company is assessing the potential impact of these amendments. (e) Newly adopted IFRS Standards Interest Rate Benchmark Reform - Phase 2 The IASB has published Interest Rate Benchmark Reform - Phase 2 (Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16) with amendments that address issues that might affect financial reporting after the reform of an interest rate benchmark, including its replacement with alternative benchmark rates. The amendments are effective for annual reporting periods beginning on or after January 1, 2021. The Company has assessed the revised impact of the amendments and concluded that they have no impact on the condensed consolidated interim financial statements. (f) Comparative figures Certain of the comparative figure have been reclassified to conform to the financial statement presentation adopted in the current year. (g) Non-controlling Non-controlling Changes in the Company’s ownership interest in a subsidiary that do not result in the loss of control of the subsidiary are accounted for as equity transactions. Non-controlling non-controlling	2. Significant accounting policies (a) Statement of compliance These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) incorporating interpretations issued by the IFRS Interpretations Committee (“IFRICs”). These consolidated financial statements were approved and authorized for issue by the Board of Directors on January 31 (b) Basis of consolidation These consolidated financial statements include the accounts of the Company and its subsidiaries. The Company’s seven subsidiaries are entities controlled by the Company. Control exists when the Company has power over an investee, when the Company is exposed, or has rights, to variable returns from the investee and when the Company has the ability to affect those returns through its power over the investee. The subsidiaries are included in the consolidated financial results of the Company from the effective date of incorporation up to the effective date of disposition or loss of control. The Company’s principal subsidiaries and their geographic location as at October 31, 2021 was as follows: Company Location Ownership interest Li-Cycle Delaware, U.S. 100 % Li-Cycle Delaware, U.S. 100 % Li-Cycle Delaware, U.S. 100 % Li-Cycle Ontario, Canada 100 % Li-Cycle Ontario, Canada 100 % Li-Cycle Switzerland 100 % Li-Cycle Singapore 100 % Intercompany transactions, balances and unrealized gains/losses on transactions between the Company and its subsidiary are eliminated. (c) Basis of preparation Change in Functional Currency: Prior to November 1, 2020, the Company had determined its functional currency was the Canadian dollar on the basis that its operating expenditures, capital expenditures and financing were primarily denominated in Canadian dollars. With increasing volume of operations, new contracts with US based suppliers, commencement of operations at its US Spoke and increasing capital expenditures in its US facilities, the Company’s operating expenditures are becoming predominantly denominated in US dollars. Additionally, due to the increase in US dollar expenses and its expansion plans in the US, the Company has obtained, and plans to continue to seek, financing in US dollars. As a result of the increasing activities in US dollars, the Company changed its functional currency to the U.S. dollar, effective November 1, 2020. Accordingly, the Company transitioned its functional and presentation currency to U.S. dollars. Transactions in currencies other than the U.S. dollar are recorded at the exchange rates on the dates of transactions. At the end of each reporting period, monetary assets and liabilities that are denominated in foreign currencies are translated at the closing rate on that date. Comparative financial information was translated from Canadian dollars into U.S. dollars in accordance with IAS 21 The Effects of Changes in Foreign Exchange Rates: (i) Assets and liabilities were translated at the closing rate at end of each reporting period; (ii) Items recognized in the statement of loss and comprehensive loss were translated at the exchange rate at the time of transaction; (iii) Equity items have been translated using the historical rate at the time of transaction; (iv) All resulting exchange differences were recognized in other comprehensive loss. (d) Cash and cash equivalents (e) Inventories Raw materials and finished goods are valued at the lower of cost and net realizable value. Cost is determined on a weighted average basis. The cost of finished goods includes the cost of raw materials and the applicable share of the cost of labour and fixed and variable production overheads. Net realizable value is the estimated selling price less the estimated cost of completion and the estimated costs necessary to make the sale. Costs of idle plant operations are expensed. At each reporting period, the Company assesses the net realizable value of inventory taking into account current market prices, current economic trends, sales trends and past experiences. (f) Convertible debt instruments (g) Loss per share The Company calculated basic and diluted loss per share data for its common shares, calculated by dividing the loss attributable to common shareholders of the Company by the weighted average number of common shares outstanding during the period. Diluted loss per share is based on the weighted average number of common shares, stock options and restricted share units (“RSUs”) outstanding at the beginning of or granted during the period, and shares to be issued upon conversion of a convertible instrument, calculated using the treasury stock method. Under this method, the proceeds from the exercise of the options are assumed to be used to repurchase the Company’s shares. The difference between the number of shares assumed purchased and the number of options assumed exercised is added to the actual number of shares outstanding to determine diluted shares outstanding for purposes of calculating diluted earnings per share. Diluted loss per share does not adjust the loss attributable to common shareholders or the weighted average number of common shares outstanding when the effect is anti-dilutive. (h) Plant and equipment Plant and equipment are stated at cost less accumulated depreciation and accumulated impairment losses net of any reversals of impairment. Where parts of an item of plant and equipment have different useful lives, they are accounted for as separate items of plant and equipment. Depreciation is charged to the consolidated statement of loss and comprehensive loss on a straight-line basis over the estimated useful lives of each part of an item of plant and equipment. The estimated useful lives are reviewed each reporting period and any changes are accounted for on a prospective basis. The estimated useful lives are as follows: Computers 3 years Vehicles 5 years Plant equipment 5 years Storage containers 10 years Leasehold improvements Shorter of term of lease or estimated useful life Repairs and maintenance costs are expensed as incurred. (i) Financial instruments Recognition The Company recognizes financial assets or financial liabilities on the consolidated statement of financial position when it becomes party to the contractual provisions of the financial instrument. Financial assets are initially measured at fair value and derecognized either when the Company has transferred substantially all the risks and rewards of ownership of the financial asset, or when cash flows expire. Financial liabilities are initially measured at fair value and are derecognized when the obligations specified in the contract is discharged, cancelled or expired. A write-off Write -off Classification and measurement The Company determines the classification of its financial instruments at initial recognition. Financial assets and financial liabilities are classified according to the following measurement categories: (i) those to be measured subsequently at fair value, either through profit or loss (“FVTPL”) or through other comprehensive income (“FVTOCI”); and (ii) those to be measured subsequently at amortized cost. The classification and measurement of financial assets after initial recognition at fair value depends on the business model for managing the financial asset and the contractual terms of the cash flows. Financial assets that are held within a business model whose objective is to collect the contractual cash flows, and that have contractual cash flows that are solely payments of principal and interest on the principal outstanding, are generally measured at amortized cost at each subsequent reporting period. Derivative financial instruments are comprised of the embedded derivative liability representing the conversion option of the convertible debt. The embedded derivative liability is measured at fair value at each reporting date. The embedded derivative liability has been classified as held-for-trading. non-current re-measurement After initial recognition at fair value, financial liabilities are classified and measured at either: (i) amortized cost; (ii) FVTPL, if the Company has made an irrevocable election at the time of recognition, or when required (for items such as instruments held for trading or derivatives); or, (iii) FVTOCI, when the change in fair market value is attributable to changes in the Company’s credit risk. The classification and measurement basis of the Company’s financial instruments are as follows: Financial Instrument Measurement Cash and cash equivalents Amortized cost Trade accounts receivables FVTPL Other accounts receivables Amortized cost Accounts payable and accrued liabilities Amortized cost Restricted share units FVTPL Warrants FVTPL Loans payable Amortized cost Lease liabilities Amortized cost Convertible debt Amortized cost Conversion feature of convertible debt FVTPL The Company reclassifies financial assets when and only when its business model for managing those assets changes. Financial liabilities are not reclassified. Transaction costs Impairment The Company assesses all information available, including on a forward-looking basis the expected credit loss associated with any financial assets carried at amortized cost. The impairment methodology applied depends on whether there has been a significant increase in credit risk. To assess whether there has been a significant increase in credit risk, the Company compares the risk of default occurring on the asset as at the reporting date with the risk of default as at the date of initial recognition based on all information available, and reasonable supportive forward-looking information. (j) Foreign currencies The reporting and functional currency of the Company is the U.S. dollar. Transactions in currencies other than the U.S. dollar are recorded at the rates of exchange prevailing on the dates of transactions. At the end of each reporting period, monetary assets and liabilities that are denominated in foreign currencies are translated at the rates prevailing at that date. (k) Government assistance and investment tax credits Government grants Amounts received or receivable resulting from government assistance programs are recognized when there is reasonable assurance that the amount of government assistance will be received, and all attached conditions will be complied with. When the amount relates to an expense item, it is recognized as a reduction to the related expense. When the amount relates to an asset, it reduces the carrying amount of the asset and is then recognized as income over the useful life of the depreciable asset by way of a reduced depreciation charge. Grants received in advance are recorded as deferred liability and amortized as a reduction to the related expense/carrying amount of asset as and when the related qualifying costs are incurred. Investment Tax Credits (“ITCs”) receivable are amounts refundable from the Canadian federal and provincial governments under the Scientific Research & Experimental Development incentive program. The amounts claimed under the program represent the amounts submitted by management based on research and development costs paid during the period and include estimates and assumptions made by management in determining the eligible expenditures. ITCs are netted against the related research and development expense when there is reasonable assurance that the Company will realize the ITCs. ITCs are subject to review and approval by tax authorities and, therefore, could be different from the amounts recorded. (l) Impairment of long-term non-financial At the end of each reporting period the carrying amounts of the Company’s assets are reviewed to determine whether there is any indication that those assets are impaired. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment, if any. The recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax If the recoverable amount of an asset is estimated to be less than its carrying amount, the carrying amount of the asset is reduced to its recoverable amount and the impairment loss is recognized in period. For an asset that does not generate largely independent cash inflows, the recoverable amount is determined for the cash generating unit to which the asset belongs. (m) Income taxes Income tax expense is comprised of current and deferred tax components. Income tax is recognized in profit or loss except to the extent that it relates to items recognized directly in equity or other comprehensive income, in which case the related tax is recognized in equity or other comprehensive income. Current tax expense is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at year end, adjusted for amendments to tax payable with regards to previous years. Deferred tax is recorded using the asset and liability method. Under this method, the Company calculates all temporary differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the period end date. Deferred tax is calculated based on the expected manner of realization or settlement of the carrying amount of assets and liabilities, using tax rates that are expected to apply to the year of realization or settlement based on tax rates and laws enacted or substantively enacted at the period end date. Deferred tax assets are recognized to the extent that it is probable that taxable profits will be available against which the deductible temporary differences and unused tax losses and tax credits can be utilized. The carrying amount of deferred tax assets is reviewed at each statement of the financial position date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company intends to settle its current tax assets and liabilities on a net basis. (n) Provisions Provisions represent liabilities of the Company for which the amount or timing is uncertain. A provision is recognized when, as a result of a past event, the Company has a present obligation (legal or constructive) that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. Where appropriate, the future cash flow estimates are adjusted to reflect risks specific to the liability. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the statement of financial position date, considering the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows. When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, the receivable is recognized as an asset if it is virtually certain that reimbursement will be received, and the amount receivable can be measured reliably. (o) Related party transactions Parties are considered to be related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Parties are also considered to be related if they are subject to common control or common significant influence. Related parties may be individuals or corporate entities. A transaction is considered to be a related party transaction when there is a transfer of resources or obligations between related parties. (p) Research and development expense Research costs are expensed as incurred. An internally-generated intangible asset arising from development (or from the development phase of an internal project) is recognised if, and only if, all of the following conditions have been demonstrated: • the technical feasibility of completing the intangible asset so that it will be available for use or sale; • the intention to complete the intangible asset and use or sell it; • the ability to use or sell the intangible asset; • how the intangible asset will generate probable future economic benefits; • the availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and • the ability to measure reliably the expenditure attributable to the intangible asset during its development. The amount initially recognised for internally-generated intangible assets is the sum of the expenditure incurred from the date when the intangible asset first meets the recognition criteria listed above. Where no internally generated intangible asset can be recognised, development expenditure is recognised in profit or loss in the period in which it is incurred. Subsequent to initial recognition, internally-generated intangible assets are reported at cost less accumulated amortisation and accumulated impairment losses, on the same basis as intangible assets that are acquired separately. No development costs have been capitalized to date. (q) Revenue recognition The Company’s principal activities generate revenues from the operation of lithium-ion Step 1: Identify the contract(s) with a customer Step 2: Identify the performance obligations in the contract Step 3: Determine the transaction price Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation The Company recognizes revenue from the following major sources: • Services of recycling lithium-ion • Sales of products which includes black mass, shredded metal and plastic Revenue is measured based on the consideration to which the Company expects to be entitled to in a contract with a customer. The Company recognizes revenue when it transfers control of a product or service to a customer. There are no significant financing components associated with the Company’s payment terms. Recycling Services revenue is recognized at a point in time upon completion of the services. Prices for services are separately identifiable within each contract. A receivable is recognized by the Company when the services are completed as this represents the point in time at which the right to consideration becomes unconditional, as only the passage of time is required before payment is due. For sale of products, revenue is recognized when control of the goods has transferred, being when the goods have been shipped to the customer’s location (delivery). A receivable is recognised by the Company when the goods are delivered to the customer as this represents the point in time at which the right to consideration becomes unconditional, as only the passage of time is required before payment is due. The Company estimates the amount of consideration to which it expects to be entitled under provisional pricing arrangements. The amount of consideration for black mass and mixed copper/aluminum sales is based on the mathematical product of: (i) market prices of the constituent metals at the date of settlement, (ii) product weight, and (iii) assay results (ratio of the constituent metals initially estimated by management and subsequently trued up to customer confirmation). Certain adjustments like handling and refining charges are also made per contractual terms with customers. Depending on the contractual terms with customers, the payment of receivables may take up to 12 months from date of shipment. Product sales and the related trade accounts receivables are measured at fair value at initial recognition and are re-estimated (r) Share capital The Company records proceeds from the issuance of its common shares as equity. Incremental costs directly attributable to the issue of new common shares are shown in equity as a deduction, net of tax, from the proceeds. (s) Financing costs Professional, consulting, regulatory and other costs directly attributable to financing transactions are recorded as deferred financing costs until the financing transactions are completed, if the completion of the transaction is considered likely; otherwise they are expensed as incurred. Share issue costs are charged to share capital when the related shares are issued. Deferred financing costs related to financing transactions that are not completed are charged to earnings. (t) Share-based compensation The Company accounts for stock options using the fair value-based method of accounting for share-based compensation. Fair values are determined using the Black-Scholes-Merton option pricing model (“BSM”). Management exercises judgment in determining the underlying share price volatility, expected life of the option, expected forfeitures and other parameters of the calculations. Compensation costs are recognized over the vesting period as an increase to share-based compensation expense and contributed surplus. If, and when, stock options are ultimately exercised, the applicable amounts of contributed surplus are transferred to share capital. The Company accounts for RSUs under the current plan as equity settled share-based payments which are measured at fair value on the grant date. The expense for RSUs is recognized over the vesting period. Upon exercise of any RSUs, the grant date fair value of the instrument is transferred to share capital. The Company accounts for outstanding RSUs by recognizing a liability for the goods or services acquired, measured initially at the fair value of the liability. At each reporting date until the liability is settled, and at the date of settlement, the fair value of the liability is remeasured, with any changes in fair value recognised in profit or loss for the year. (u) Significant accounting estimates and judgments The preparation of the financial statements in conformity with IFRS requires management to make judgements, estimates and assumptions that are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which affect the application of accounting policies and the reported amounts of assets, liabilities and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised and in any future periods affected. Significant estimates include: (a) the determination and valuation of deferred income tax assets and liabilities; (b) the determination of the useful life and impairment of the plant and equipment; (c) the valuation and measurement of the convertible debt and the related conversion features; (d) the valuation and recognition of ITCs; and (e) the valuation of share-based compensation. Critical judgements in applying accounting policies that have the most significant effect on the amounts recognized in the financial statements include the following: (a) the determination of the functional currency of the Company and its subsidiaries; (b) the determination of the revenue recognition policy with regards to transaction price; (c) the evaluation of the Company’s ability to continue as a going concern; and (d) the valuation of inventory with regards to incremental cost to completion for raw materials and determination of net realizable value. (e) the valuation of the fair value of consideration transferred in the business combination (v) Leases The Company assesses whether a contract is or contains a lease, at inception of the contract. The Company recognises a right-of-use The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by using the rate implicit in the lease. If this rate cannot be readily determined, the Company uses its incremental borrowing rate. Lease payments included in the measurement of the lease liability comprise: • Fixed lease payments (including in-substance • Variable lease payments that depend on an index or rate, initially measured using the index or rate at the commencement date; • The amount expected to be payable by the lessee under residual value guarantees; • The exercise price of purchase options, if the lessee is reasonably certain to exercise the options; and • Payments of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease. The lease liability is presented as a separate line in the consolidated statement of financial position. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments made. The Company remeasures the lease liability (and makes a corresponding adjustment to the related right-of-use • The lease term has changed or there is a significant event or change in circumstances resulting in a change in the assessment of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate. • The lease payments change due to changes in an index or rate or a change in expected payment under a guaranteed residual value, in which cases the lease liability is remeasured by discounting the revised lease payments using an unchanged discount rate (unless the lease payments change is due to a change in a floating interest rate, in which case a revised discount rate is used). • A lease contract is modified and the lease modification is not accounted for as a separate lease, in which case the lease liability is remeasured based on the lease term of the modified lease by discounting the revised lease payments using a revised discount rate at the effective date of the modification. The Company made several such adjustments during the periods presented, see Note 15. The right-of-use Whenever the Company incurs an obligation for costs to dismantle and remove a leased asset, restore the site on which it is located or restore the underlying asset to the condition required by the terms and conditions of the lease, a provision is recognised and measured under IAS 37. To the extent that the costs relate to a right-of-use right-of-use Right-of-use right-of-use right-of-use right-of-use The right-of-use The Company applies IAS 36 to determine whether a right-of-use Variable rents that do not depend on an index or rate are not included in the measurement the lease liability and the right-of-use As a practical expedient, IFRS 16 Leases (“IFRS 16”) permits a lessee not to separate non-lease non-lease (w) Restoration provisions Provisions for the costs to restore leased plant assets to their original condition, as required by the terms and conditions of the lease, are recognised when the obligation is incurred, either at the commencement date or as a consequence of having used the underlying asset during a particular period of the lease, at the directors’ best estimate of the expenditure that would be required to restore the assets. Estimates are regularly reviewed and adjusted as appropriate for new circumstances.

The KSP Note will mature on September 29, 2026 unless earlier repurchased, redeemed or converted. Interest on the KSP Note is payable semi-annually, and Li-Cycle in-kind On the first interest payment date of December 31, 2021, the Company elected to pay the accrued interest in kind by issuing a new note (the “PIK Note”) for the amount of $1,827,778 under the same terms as the original KSP Note, in lieu of cash payments. The conversion feature has been recorded as an embedded derivative liability since the conversion ratio does not always result in a conversion of a fixed dollar amount of liability for a fixed number of shares. The KSP Note had an initial conversion price of approximately $13.43 per Li-Cycle 7-day Li-Cycle’s Li-Cycle obligations through the delivery of its own common shares. As at April 30, 2022, no conversions had taken place. The fair value of the embedded derivatives upon issuance of the original KSP Note was determined to be a liability of $27,681,043 whereas the remaining $72,318,957, net of transaction costs of $1,599,737, was allocated to the principal portion of the debt. During the three and six months ended April 30, 2022, the Company recognized a fair value gain of $2,861,556 and fair value gain of $17,559,830 on the embedded derivatives, respectively. The embedded derivatives were valued using the Barrier option pricing model. The assumptions used in the model were as follows: September 29, 2021 October 31, 2021 April 30, 2022 Risk free interest rate 1.06% 1.23% 3.07% Expected life of options 5 years 4.92 years 4.42 years Expected dividend yield 0.0% 0.0% 0.0% Expected stock price volatility 66% 62% 65% Share Price 12.56 12.94 6.49 Expected volatility was determined by calculating the average implied volatility of a group of listed entities that are considered similar in nature to the Company.	10.

The fair value of the embedded derivative liability upon issuance was $96,548. The residual value of $289,643 was allocated to the convertible loan payable which has an effective interest rate of 9.62%. On December 27, 2019, the convertible debenture with SCA was converted to common shares as a result of the additional funding exceeding $10 million and thereby triggering the “qualifying transaction” clause of the debenture agreement. Per the terms of the agreement, the principal amount of $386,190 plus accrued interest of $55,788 was converted at a 20% discount to the Series B share price of $40.05 resulting in the issuance of 13,436 common shares. On September 29, 2021, the Company issued a convertible note (the “Note”) for a principal amount of $100,000,000 to Koch Strategic Platforms (“KSP”), a subsidiary of Koch Investments Group. The Note will mature on September 29, 2026 unless earlier repurchased, redeemed or converted. Interest on the Note will be payable semi-annually, and Li-Cycle in-kind (“PIK”), at its election. Interest payments made in cash will be based on an interest rate of LIBOR plus 5.0% per year, and PIK interest payments will be based on an interest rate of LIBOR plus 6.0% per year. Under the terms of the Note, LIBOR has a floor of 1% and a cap of 2%. With the retirement of the LIBOR at the end of 2021, the interest rates will instead be based on the sum of the Secured Overnight Financing Rate (“SOFR”) and the average spread between the SOFR and LIBOR during the three-month period of time ending on the date on which the LIBOR interest rate ceases to be published. The PIK election results in a new Note under the same terms as the original note, issued in lieu of interest payments with an issuance date on the applicable interest date. At October 31, 2021, the Company has elected to pay interest on the Note using the PIK election. The conversion feature has been recorded as an embedded derivative liability since the conversion ratio does not always result in a conversion of a fixed dollar amount of liability for a fixed number of shares. The Note will have an initial conversion price of approximately Li-Cycle 7-day Li-Cycle’s Li-Cycle The fair value of the embedded derivatives upon issuance was determined to be a liability of $27,681,043 whereas the remaining $72,318,957, net of transaction costs of $1,599,737, was allocated to the principal of the debt. During the twelve months ended October 31, 2021, the Company recognized a fair value loss of 1,347,895 on the embedded derivatives. The embedded derivatives were valued using the Barrier option pricing model. The assumptions used in the model were as follows: September 29, 2021 October 31, 2021 Risk free interest rate 1.06% 1.23% Expected life of options 5 years 4.92 years Expected dividend yield 0.0% 0.0% Expected stock price volatility 66% 62% Share Price 12.56 12.94 Expected volatility was determined by calculating the average implied volatility of a group of listed entities that are considered similar in nature to the Company.

The Public Warrants have an exercise price of $11.50 per share, with a redemption price of $0.01 per warrant if the share price is above $10.00, on a cashless basis. If the share price is above $18.00 for any 20 trading days within the 30 trading day period ending three trading days before the notice of redemption, the redemption price will be $0.10 on a cash basis. The Private Warrants have an exercise price of $ per shares, redeemable only at such time that the share price of the Company is between $ and $ , at the above prices. The Private Warrants were not transferable until days after the close of the business combination, which has passed as of writing. If the Private Placement Warrants are transferred to parties other than the Company’s sponsor or its permitted transferees, the Private Placement Warrants will cease to be Private Placement Warrants and will become Public Warrants. On October 15, 2021, 100 warrants were exercised for 100 shares for which the Company received $1,150. Warrants are remeasured through profit or loss at each period end, using first level inputs. At October 31, 2021, the publicly traded fair market value for each warrant was $3.57 with a total liability of $82,109,334, recognizing a total loss of $33,809,634 in the twelve months ended October 31, 2021.

Financial instruments and financial risk factors	16. Financial instruments and financial risk factors Fair values The Company’s financial instruments consist of cash, accounts receivables, accounts payable and accrued liabilities, loans payable. The carrying amounts of cash, Harmonized Sales Taxes receivable, other receivables, accounts payable and accrued liabilities approximately fair value due to the short-term maturity of these instruments. Fair value hierarchy levels 1 to 3 are based on the degree to which the fair value is observable: • Level 1 fair value measurements are those derived from quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2 fair value measurements are those derived from inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e., as prices) or indirectly (i.e., derived from prices); and • Level 3 fair value measurements are those derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data (unobservable inputs). There were no transfers between the levels during the current or prior year. The Company’s financial assets measured at fair value on a recurring basis are measured under level 1 of the hierarchy and were calculated as follows: Balance Level 2 $ $ As at April 30, 2022 Accounts receivable 11,501,265 11,501,265 11,501,265 11,501,265 As at October 31, 2021 Accounts receivable 4,072,701 4,072,701 4,072,701 4,072,701 See Note 3 above for additional details related to measurement of accounts receivable. The Company’s financial liabilities measured at fair value on a recurring basis are measured under level 1 and 2 of the hierarchy and were calculated as follows: Balance Level 1 Level 2 $ $ $ As at April 30, 2022 Conversion feature of convertible debt (see Note 11) 11,469,108 — 11,469,108 11,469,108 — 11,469,108 As at October 31, 2021 Conversion feature of convertible debt (see Note 11) 29,028,938 — 29,028,938 Warrants (see Note 12) 82,109,334 53,549,989 28,559,344 111,138,272 53,549,989 57,588,282 Currency risk The Company is exposed to currency risk as its cash is mainly denominated in U.S. dollars, but its operations require Canadian dollars and other currencies, in addition to U.S. dollars. At April 30, 2022, the Company had Canadian dollar denominated cash of approximately Cdn. $4,128,174 and Canadian dollar denominated net liabilities and loans payable of approximately Cdn. $24,778,777. The remaining amounts were denominated in U.S. dollars and immaterial amounts of other currencies. Gains and losses arising upon translation of these amounts into U.S. dollars for inclusion in the condensed consolidated interim financial statements are recorded in other income and expenses as foreign exchange. A 5% strengthening of the Canadian dollar versus the U.S. dollar, at April 30, 2022, would have increased the foreign exchange loss for the period by approximately $803,993 while a 5% weakening of the Canadian dollar would have had approximately the equal but opposite effect. This analysis assumes that all other variables remain constant. Interest rate risk Interest rate risk is the risk arising from the effect of changes in prevailing interest rates on the Company’s financial instruments. The Company is exposed to interest rate risk, as it has variable interest rate debt that includes an interest rate floor and cap, see Note 11. Credit, liquidity, and market risks Credit risks associated with cash are minimal as the Company deposits the majority of its cash with a large Canadian financial institution. The Company’s credit risks associated with receivables are managed and exposure to potential loss is assessed as minimal. The Company is exposed to commodity price movements for the inventory it holds and the products it produces. Commodity price risk management activities are currently limited to monitoring market prices. The following table sets out the Company’s exposure, as of April 30, 2022, in relation to the impact of movements in the Cobalt and Nickel price for the provisionally invoiced sales volume: Cobalt Nickel April 30, October 31, April 30, October 31, $ $ $ $ Metric tonnes subject to fair value pricing adjustments 2,595 1,728 2,595 1,728 10% increase in prices 681,592 303,351 1,024,667 448,266 10 % decrease in prices (681,592 ) (303,351 ) (1,024,667 ) (448,266 ) The Company’s revenue and accounts receivable primarily come from two key customers, as further disclosed in Note 3. The Company manages this risk by engaging with reputable multi-national corporations in stable jurisdictions and performing a review of a potential customer’s financial health prior to engaging in business. Management has established an appropriate liquidity risk management framework for the management of the Company’s short-term, medium and long-term funding and liquidity requirements. Capital risk management The Company manages its capital to ensure that entities in the Company will be able to continue as a going concern while maximizing the return to shareholders through the optimization of the debt and equity balance. The capital structure of the Company consists of net debt (borrowings after deducting cash and cash equivalents) and equity of the Company (comprising issued share capital, contributed surplus and accumulated deficit as disclosed in Note 13). The Company is not subject to any externally imposed capital requirements.

Financial instruments and financial risk factors Fair values The Company’s financial instruments consist of cash, accounts receivables, accounts payable and accrued liabilities, loans payable. The fair values of the cash, trade receivables, accounts payable and accrued liabilities approximate their carrying amounts because of their current nature. Fair value hierarchy levels 1 to 3 are based on the degree to which the fair value is observable: • Level 1 fair value measurements are those derived from quoted prices (unadjusted) in active markets for identical assets or liabilities; • Level 2 fair value measurements are those derived from inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and • Level 3 fair value measurements are those derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data (unobservable inputs).

At October 31, 2021, the Company had Canadian dollar denominated cash of approximately Cdn. $1.3 million and Canadian dollar denominated net liabilities and loans payable of approximately Cdn. $23.9 million. The remaining amounts were denominated in U.S. dollars and immaterial amounts of other currencies. Gains and losses arising upon translation of these amounts into U.S. dollars for inclusion in the consolidated financial statements are recorded in other income and expenses as foreign exchange. A % strengthening of the Canadian dollar versus the U.S. dollar, at October , , would have increased the foreign exchange loss for the year by approximately $ million while a % weakening of the Canadian dollar would have had approximately the equal but opposite effect. This analysis assumes that all other variables remain constant. Interest rate risk Interest rate risk is the risk arising from the effect of changes in prevailing interest rates on the Company’s financial instruments. The Company is exposed to interest rate risk, as it has variable interest rate debt, see Note 10. Credit, liquidity, and market risks Credit risks associated with cash are minimal as the Company deposits majority of its cash with a large Canadian financial institution. The Company’s credit risks associated with receivables are managed and exposure to potential loss is assessed as minimal.

Subsequent Events	20. Subsequent events On May 1, 2022, Spring Creek Capital, LLC assigned the KSP Note and the PIK Note (together, the “2021 Convertible Notes”) to an affiliate, Wood River Capital, LLC (“Wood River Capital”) and each of Spring Creek Capital and Wood River Capital signed a joinder agreement under which Wood River Capital agreed to become a party to, to be bound by and to comply with the KSP Note Purchase Agreement and related documents; provided, however, that such assignment did not relieve Spring Creek Capital of its obligations thereunder. This assignment does not change the previously agreed upon terms of the 2021 Convertible Notes. On May 12, 2022, the Company announced the successful completion of the previously announced $50 million aggregate investment in common shares of the Company by LG Energy Solution, Ltd. (“LGES”) and LG Chem, Ltd. (“LGC”). The Company issued 5,300,352 shares at an average price of $9.43 per common shares to LGES and LGC (being 2,650,176 common shares each). The investment was split into two tranches: (i) an initial tranche of 4,416,960 common shares, in the aggregate, at a price of $10.00 per share (for an aggregate initial tranche subscription price of approximately $44.2 million), and (ii) a second tranche of 883,392 common shares, in the aggregate, at a price of $6.60 per share (for an aggregate second tranche subscription price of approximately $5.8 million). On May 31, 2022, the Company entered into a Note Purchase Agreement (the “Glencore Note Purchase Agreement”) with Glencore Ltd. (“Glencore”), a subsidiary of Glencore plc (LON: GLEN) and issued a convertible note (the “Glencore Note”) for a principal amount of $200 million to Glencore. The Glencore Note will mature on May 31, 2027 unless earlier repurchased, redeemed or converted. Interest on the Glencore Note is payable semi-annually, and Li-Cycle in-kind The principal and accrued interest owing under the Glencore Note may be converted at any time by the holder into the Company’s common shares at a per share price equal to $9.95 (the “Conversion Price”), subject to adjustments. The Company may redeem the Glencore Note at any time by payment of an amount in cash equal to 100% of the outstanding principal amount of the Glencore Note and all accrued interest owing under the Glencore Note. In connection with any optional redemption and provided that the holder of the Glencore Note has not elected to convert the Glencore Note into common shares following receipt of notice of such optional redemption, the Company must issue warrants (the “Warrants”) to the holder of the Glencore Note on the optional redemption date that entitle the holder to acquire, until the maturity date of the Glencore Note, a number of common shares equal to the principal amount of the Glencore Note being redeemed divided by the then applicable Conversion Price. The initial exercise price of the Warrants will be equal to the Conversion Price as of the optional redemption date.	24. Subsequent events On December 14, 2021, the Company announced a non-binding off-take off-take Li-Cycle million investment). Under the terms of the proposed investment, LG Chem and LG Energy Solution will each subscribe for 2,208,480 Common Shares at a price of $11.32 per share, for an aggregate investment in the Company of $50 million (the “Investment”). The subscription price per Common Share is based on a 30-day volume-weighted average price of the Common Shares prior to LGES’ investment committee approval of LGES’ participation in the Investment on October 28th, 2021. The closing of the Investment is conditional on the parties entering into mutually acceptable definitive commercial agreements regarding the supply of nickel-bearing lithium-ion Li-Cycle off-take Li-Cycle On December 31, 2021, the Company exercised its election to pay interest on its $100,000,000 convertible note to Koch Strategic Platforms through a payment in-kind On December 27, 2021, the Company announced that it will redeem all of its warrants to purchase common shares of the Company that remain outstanding at 5:00 p.m. New York City time on January 26, 2022 (the “Redemption Date”) for a redemption price of $0.10 per Warrant. Based on the Redemption Fair Market Value that was announced on January 11, 2022, Warrant holders who surrendered their Warrants on a “Make-Whole Exercise” prior to the Redemption Date received Common Shares per Warrant. As of January 30, 2022, (i) 9,678 warrants have been exercised at the exercise price of $11.50 per common share, and (ii) 22,540,651 warrants have been surrendered by holders in the Make-Whole Exercise. The remaining 449,665 unexercised warrants will be redeemed at $0.10 per warrant.

Basis of preparation	(c) Basis of preparation These condensed consolidated interim financial statements are presented in U.S. dollars, which is the Company’s functional currency. (d) New and revised IFRS Standards issued but not yet effective At the date of authorization of these financial statements, the Company has not applied the following new and revised IFRS Standards that have been issued but are not yet effective. Amendments to IFRS 3 Reference to the Conceptual Framework IFRS 17 (including the June 2020 amendments to IFRS 17) Insurance Contracts Annual Improvements to IFRS Standards 2018-2020 Amendments to IFRS 1 First-time Adoption of International Financial Reporting Standards, IFRS 9 Financial Instruments, IFRS 16 Leases, and IAS 41 Agriculture Amendments to IAS 1 Disclosure of Accounting Policies Amendments to IAS 1 Classifying liabilities as current or non-current Amendments to IAS 8 Definition of Accounting Estimates Amendments to IAS 12 Deferred Tax related to Assets and Liabilities arising from a Single Transaction Amendments to IAS 16 Property, Plant and Equipment—Proceeds before Intended Use Amendments to IAS 37 Onerous Contracts—Cost of Fulfilling a Contract The adoption of the IFRS Standards listed above are not expected to have a material impact on the financial statements of the Company in future periods, except as noted below. Amendments to IAS 1 Presentation of Financial Statements and IFRS Practice Statement 2 Making Materiality Judgements—Disclosure of Accounting Policies The amendments change the requirements in IAS 1 with regard to disclosure of accounting policies. The amendments replace all instances of the term ‘significant accounting policies’ with ‘material accounting policy information’. Accounting policy information is material if, when considered together with other information included in an entity’s financial statements, it can reasonably be expected to influence decisions that the primary users of general purpose financial statements make on the basis of those financial statements. The supporting paragraphs in IAS 1 are also amended to clarify that accounting policy information that relates to immaterial transactions, other events or conditions is immaterial and need not be disclosed. Accounting policy information may be material because of the nature of the related transactions, other events or conditions, even if the amounts are immaterial. However, not all accounting policy information relating to material transactions, other events or conditions is itself material. The International Accounting Standards Board has also developed guidance and examples to explain and demonstrate the application of the ‘four-step materiality process’ described in IFRS Practice Statement 2. The amendments to IAS 1 are effective for annual periods beginning on or after 1 January 2023, with earlier application permitted and are applied prospectively. The Company is assessing the potential impact of these amendments.	(c) Basis of preparation Change in Functional Currency: Prior to November 1, 2020, the Company had determined its functional currency was the Canadian dollar on the basis that its operating expenditures, capital expenditures and financing were primarily denominated in Canadian dollars. With increasing volume of operations, new contracts with US based suppliers, commencement of operations at its US Spoke and increasing capital expenditures in its US facilities, the Company’s operating expenditures are becoming predominantly denominated in US dollars. Additionally, due to the increase in US dollar expenses and its expansion plans in the US, the Company has obtained, and plans to continue to seek, financing in US dollars. As a result of the increasing activities in US dollars, the Company changed its functional currency to the U.S. dollar, effective November 1, 2020. Accordingly, the Company transitioned its functional and presentation currency to U.S. dollars. Transactions in currencies other than the U.S. dollar are recorded at the exchange rates on the dates of transactions. At the end of each reporting period, monetary assets and liabilities that are denominated in foreign currencies are translated at the closing rate on that date. Comparative financial information was translated from Canadian dollars into U.S. dollars in accordance with IAS 21 The Effects of Changes in Foreign Exchange Rates: (i) Assets and liabilities were translated at the closing rate at end of each reporting period; (ii) Items recognized in the statement of loss and comprehensive loss were translated at the exchange rate at the time of transaction; (iii) Equity items have been translated using the historical rate at the time of transaction; (iv) All resulting exchange differences were recognized in other comprehensive loss.
Cash and cash equivalents		(d) Cash and cash equivalents Cash consists of cash deposits with financial institutions. Cash equivalents consists of overnight guaranteed investment certificates with financial institutions.
Inventories		(e) Inventories Raw materials and finished goods are valued at the lower of cost and net realizable value. Cost is determined on a weighted average basis. The cost of finished goods includes the cost of raw materials and the applicable share of the cost of labour and fixed and variable production overheads. Net realizable value is the estimated selling price less the estimated cost of completion and the estimated costs necessary to make the sale. Costs of idle plant operations are expensed. At each reporting period, the Company assesses the net realizable value of inventory taking into account current market prices, current economic trends, sales trends and past experiences.
Convertible debt instruments		(f) Convertible debt instruments The components of convertible debt instruments issued by the Company are classified separately as financial liabilities and equity in accordance with the substance of the contractual arrangements and the definitions of a financial liability and an equity instrument. The debt element of the instruments is classified as a liability and recorded as the present value of the Company’s obligation to make future interest payments in cash and settle the redemption value of the instrument in cash. The carrying value of the debt element is accreted to the original face value of the instruments, over their life, using the effective interest method. If the conversion option is classified as equity, its value is determined by deducting the amount of the liability component from the fair value of the compound instrument as a whole. If the conversion option is classified as a liability and requires bifurcation, it is bifurcated as an embedded derivative unless the issuer elects to apply the fair value option to the convertible debt. The embedded derivative liability is initially recognized at fair value and classified as derivatives in the statement of financial position. Changes in the fair value of the embedded derivative liability are subsequently accounted for directly through the income statement.​​​​​​​
Loss per share		(g) Loss per share The Company calculated basic and diluted loss per share data for its common shares, calculated by dividing the loss attributable to common shareholders of the Company by the weighted average number of common shares outstanding during the period. Diluted loss per share is based on the weighted average number of common shares, stock options and restricted share units (“RSUs”) outstanding at the beginning of or granted during the period, and shares to be issued upon conversion of a convertible instrument, calculated using the treasury stock method. Under this method, the proceeds from the exercise of the options are assumed to be used to repurchase the Company’s shares. The difference between the number of shares assumed purchased and the number of options assumed exercised is added to the actual number of shares outstanding to determine diluted shares outstanding for purposes of calculating diluted earnings per share. Diluted loss per share does not adjust the loss attributable to common shareholders or the weighted average number of common shares outstanding when the effect is anti-dilutive.
Plant and equipment		(h) Plant and equipment Plant and equipment are stated at cost less accumulated depreciation and accumulated impairment losses net of any reversals of impairment. Where parts of an item of plant and equipment have different useful lives, they are accounted for as separate items of plant and equipment. Depreciation is charged to the consolidated statement of loss and comprehensive loss on a straight-line basis over the estimated useful lives of each part of an item of plant and equipment. The estimated useful lives are reviewed each reporting period and any changes are accounted for on a prospective basis. The estimated useful lives are as follows: Computers 3 years Vehicles 5 years Plant equipment 5 years Storage containers 10 years Leasehold improvements Shorter of term of lease or estimated useful life Repairs and maintenance costs are expensed as incurred.
Financial instruments		(i) Financial instruments Recognition The Company recognizes financial assets or financial liabilities on the consolidated statement of financial position when it becomes party to the contractual provisions of the financial instrument. Financial assets are initially measured at fair value and derecognized either when the Company has transferred substantially all the risks and rewards of ownership of the financial asset, or when cash flows expire. Financial liabilities are initially measured at fair value and are derecognized when the obligations specified in the contract is discharged, cancelled or expired. A write-off Write -off Classification and measurement The Company determines the classification of its financial instruments at initial recognition. Financial assets and financial liabilities are classified according to the following measurement categories: (i) those to be measured subsequently at fair value, either through profit or loss (“FVTPL”) or through other comprehensive income (“FVTOCI”); and (ii) those to be measured subsequently at amortized cost. The classification and measurement of financial assets after initial recognition at fair value depends on the business model for managing the financial asset and the contractual terms of the cash flows. Financial assets that are held within a business model whose objective is to collect the contractual cash flows, and that have contractual cash flows that are solely payments of principal and interest on the principal outstanding, are generally measured at amortized cost at each subsequent reporting period. Derivative financial instruments are comprised of the embedded derivative liability representing the conversion option of the convertible debt. The embedded derivative liability is measured at fair value at each reporting date. The embedded derivative liability has been classified as held-for-trading. non-current re-measurement After initial recognition at fair value, financial liabilities are classified and measured at either: (i) amortized cost; (ii) FVTPL, if the Company has made an irrevocable election at the time of recognition, or when required (for items such as instruments held for trading or derivatives); or, (iii) FVTOCI, when the change in fair market value is attributable to changes in the Company’s credit risk. The classification and measurement basis of the Company’s financial instruments are as follows: Financial Instrument Measurement Cash and cash equivalents Amortized cost Trade accounts receivables FVTPL Other accounts receivables Amortized cost Accounts payable and accrued liabilities Amortized cost Restricted share units FVTPL Warrants FVTPL Loans payable Amortized cost Lease liabilities Amortized cost Convertible debt Amortized cost Conversion feature of convertible debt FVTPL The Company reclassifies financial assets when and only when its business model for managing those assets changes. Financial liabilities are not reclassified. Transaction costs Impairment The Company assesses all information available, including on a forward-looking basis the expected credit loss associated with any financial assets carried at amortized cost. The impairment methodology applied depends on whether there has been a significant increase in credit risk. To assess whether there has been a significant increase in credit risk, the Company compares the risk of default occurring on the asset as at the reporting date with the risk of default as at the date of initial recognition based on all information available, and reasonable supportive forward-looking information.
Foreign currencies		(j) Foreign currencies The reporting and functional currency of the Company is the U.S. dollar. Transactions in currencies other than the U.S. dollar are recorded at the rates of exchange prevailing on the dates of transactions. At the end of each reporting period, monetary assets and liabilities that are denominated in foreign currencies are translated at the rates prevailing at that date.
Government assistance and investment tax credits		(k) Government assistance and investment tax credits Government grants Amounts received or receivable resulting from government assistance programs are recognized when there is reasonable assurance that the amount of government assistance will be received, and all attached conditions will be complied with. When the amount relates to an expense item, it is recognized as a reduction to the related expense. When the amount relates to an asset, it reduces the carrying amount of the asset and is then recognized as income over the useful life of the depreciable asset by way of a reduced depreciation charge. Grants received in advance are recorded as deferred liability and amortized as a reduction to the related expense/carrying amount of asset as and when the related qualifying costs are incurred. Investment Tax Credits (“ITCs”) receivable are amounts refundable from the Canadian federal and provincial governments under the Scientific Research & Experimental Development incentive program. The amounts claimed under the program represent the amounts submitted by management based on research and development costs paid during the period and include estimates and assumptions made by management in determining the eligible expenditures. ITCs are netted against the related research and development expense when there is reasonable assurance that the Company will realize the ITCs. ITCs are subject to review and approval by tax authorities and, therefore, could be different from the amounts recorded.
Impairment of long-term non-financial assets		(l) Impairment of long-term non-financial At the end of each reporting period the carrying amounts of the Company’s assets are reviewed to determine whether there is any indication that those assets are impaired. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment, if any. The recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax If the recoverable amount of an asset is estimated to be less than its carrying amount, the carrying amount of the asset is reduced to its recoverable amount and the impairment loss is recognized in period. For an asset that does not generate largely independent cash inflows, the recoverable amount is determined for the cash generating unit to which the asset belongs.
Income taxes		(m) Income taxes Income tax expense is comprised of current and deferred tax components. Income tax is recognized in profit or loss except to the extent that it relates to items recognized directly in equity or other comprehensive income, in which case the related tax is recognized in equity or other comprehensive income. Current tax expense is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at year end, adjusted for amendments to tax payable with regards to previous years. Deferred tax is recorded using the asset and liability method. Under this method, the Company calculates all temporary differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the period end date. Deferred tax is calculated based on the expected manner of realization or settlement of the carrying amount of assets and liabilities, using tax rates that are expected to apply to the year of realization or settlement based on tax rates and laws enacted or substantively enacted at the period end date. Deferred tax assets are recognized to the extent that it is probable that taxable profits will be available against which the deductible temporary differences and unused tax losses and tax credits can be utilized. The carrying amount of deferred tax assets is reviewed at each statement of the financial position date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company intends to settle its current tax assets and liabilities on a net basis.
Provisions		(n) Provisions Provisions represent liabilities of the Company for which the amount or timing is uncertain. A provision is recognized when, as a result of a past event, the Company has a present obligation (legal or constructive) that can be estimated reliably, and it is probable that an outflow of economic benefits will be required to settle the obligation. Where appropriate, the future cash flow estimates are adjusted to reflect risks specific to the liability. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the statement of financial position date, considering the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows. When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, the receivable is recognized as an asset if it is virtually certain that reimbursement will be received, and the amount receivable can be measured reliably.
Related party transactions		(o) Related party transactions Parties are considered to be related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Parties are also considered to be related if they are subject to common control or common significant influence. Related parties may be individuals or corporate entities. A transaction is considered to be a related party transaction when there is a transfer of resources or obligations between related parties.
Research and development expense		(p) Research and development expense Research costs are expensed as incurred. An internally-generated intangible asset arising from development (or from the development phase of an internal project) is recognised if, and only if, all of the following conditions have been demonstrated: • the technical feasibility of completing the intangible asset so that it will be available for use or sale; • the intention to complete the intangible asset and use or sell it; • the ability to use or sell the intangible asset; • how the intangible asset will generate probable future economic benefits; • the availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and • the ability to measure reliably the expenditure attributable to the intangible asset during its development. The amount initially recognised for internally-generated intangible assets is the sum of the expenditure incurred from the date when the intangible asset first meets the recognition criteria listed above. Where no internally generated intangible asset can be recognised, development expenditure is recognised in profit or loss in the period in which it is incurred. Subsequent to initial recognition, internally-generated intangible assets are reported at cost less accumulated amortisation and accumulated impairment losses, on the same basis as intangible assets that are acquired separately. No development costs have been capitalized to date.
Revenue recognition		(q) Revenue recognition The Company’s principal activities generate revenues from the operation of lithium-ion Step 1: Identify the contract(s) with a customer Step 2: Identify the performance obligations in the contract Step 3: Determine the transaction price Step 4: Allocate the transaction price to the performance obligations in the contract Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation The Company recognizes revenue from the following major sources: • Services of recycling lithium-ion • Sales of products which includes black mass, shredded metal and plastic Revenue is measured based on the consideration to which the Company expects to be entitled to in a contract with a customer. The Company recognizes revenue when it transfers control of a product or service to a customer. There are no significant financing components associated with the Company’s payment terms. Recycling Services revenue is recognized at a point in time upon completion of the services. Prices for services are separately identifiable within each contract. A receivable is recognized by the Company when the services are completed as this represents the point in time at which the right to consideration becomes unconditional, as only the passage of time is required before payment is due. For sale of products, revenue is recognized when control of the goods has transferred, being when the goods have been shipped to the customer’s location (delivery). A receivable is recognised by the Company when the goods are delivered to the customer as this represents the point in time at which the right to consideration becomes unconditional, as only the passage of time is required before payment is due. The Company estimates the amount of consideration to which it expects to be entitled under provisional pricing arrangements. The amount of consideration for black mass and mixed copper/aluminum sales is based on the mathematical product of: (i) market prices of the constituent metals at the date of settlement, (ii) product weight, and (iii) assay results (ratio of the constituent metals initially estimated by management and subsequently trued up to customer confirmation). Certain adjustments like handling and refining charges are also made per contractual terms with customers. Depending on the contractual terms with customers, the payment of receivables may take up to 12 months from date of shipment. Product sales and the related trade accounts receivables are measured at fair value at initial recognition and are re-estimated
Share capital		(r) Share capital The Company records proceeds from the issuance of its common shares as equity. Incremental costs directly attributable to the issue of new common shares are shown in equity as a deduction, net of tax, from the proceeds.
Financing costs		(s) Financing costs Professional, consulting, regulatory and other costs directly attributable to financing transactions are recorded as deferred financing costs until the financing transactions are completed, if the completion of the transaction is considered likely; otherwise they are expensed as incurred. Share issue costs are charged to share capital when the related shares are issued. Deferred financing costs related to financing transactions that are not completed are charged to earnings.
Share-based compensation		(t) Share-based compensation The Company accounts for stock options using the fair value-based method of accounting for share-based compensation. Fair values are determined using the Black-Scholes-Merton option pricing model (“BSM”). Management exercises judgment in determining the underlying share price volatility, expected life of the option, expected forfeitures and other parameters of the calculations. Compensation costs are recognized over the vesting period as an increase to share-based compensation expense and contributed surplus. If, and when, stock options are ultimately exercised, the applicable amounts of contributed surplus are transferred to share capital. The Company accounts for RSUs under the current plan as equity settled share-based payments which are measured at fair value on the grant date. The expense for RSUs is recognized over the vesting period. Upon exercise of any RSUs, the grant date fair value of the instrument is transferred to share capital. The Company accounts for outstanding RSUs by recognizing a liability for the goods or services acquired, measured initially at the fair value of the liability. At each reporting date until the liability is settled, and at the date of settlement, the fair value of the liability is remeasured, with any changes in fair value recognised in profit or loss for the year.
Significant accounting estimates and judgments		(u) Significant accounting estimates and judgments The preparation of the financial statements in conformity with IFRS requires management to make judgements, estimates and assumptions that are based on historical experience and various other factors that are believed to be reasonable under the circumstances, the results of which affect the application of accounting policies and the reported amounts of assets, liabilities and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised and in any future periods affected. Significant estimates include: (a) the determination and valuation of deferred income tax assets and liabilities; (b) the determination of the useful life and impairment of the plant and equipment; (c) the valuation and measurement of the convertible debt and the related conversion features; (d) the valuation and recognition of ITCs; and (e) the valuation of share-based compensation. Critical judgements in applying accounting policies that have the most significant effect on the amounts recognized in the financial statements include the following: (a) the determination of the functional currency of the Company and its subsidiaries; (b) the determination of the revenue recognition policy with regards to transaction price; (c) the evaluation of the Company’s ability to continue as a going concern; and (d) the valuation of inventory with regards to incremental cost to completion for raw materials and determination of net realizable value. (e) the valuation of the fair value of consideration transferred in the business combination
Leases		(v) Leases The Company assesses whether a contract is or contains a lease, at inception of the contract. The Company recognises a right-of-use The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by using the rate implicit in the lease. If this rate cannot be readily determined, the Company uses its incremental borrowing rate. Lease payments included in the measurement of the lease liability comprise: • Fixed lease payments (including in-substance • Variable lease payments that depend on an index or rate, initially measured using the index or rate at the commencement date; • The amount expected to be payable by the lessee under residual value guarantees; • The exercise price of purchase options, if the lessee is reasonably certain to exercise the options; and • Payments of penalties for terminating the lease, if the lease term reflects the exercise of an option to terminate the lease. The lease liability is presented as a separate line in the consolidated statement of financial position. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments made. The Company remeasures the lease liability (and makes a corresponding adjustment to the related right-of-use • The lease term has changed or there is a significant event or change in circumstances resulting in a change in the assessment of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate. • The lease payments change due to changes in an index or rate or a change in expected payment under a guaranteed residual value, in which cases the lease liability is remeasured by discounting the revised lease payments using an unchanged discount rate (unless the lease payments change is due to a change in a floating interest rate, in which case a revised discount rate is used). • A lease contract is modified and the lease modification is not accounted for as a separate lease, in which case the lease liability is remeasured based on the lease term of the modified lease by discounting the revised lease payments using a revised discount rate at the effective date of the modification. The Company made several such adjustments during the periods presented, see Note 15. The right-of-use Whenever the Company incurs an obligation for costs to dismantle and remove a leased asset, restore the site on which it is located or restore the underlying asset to the condition required by the terms and conditions of the lease, a provision is recognised and measured under IAS 37. To the extent that the costs relate to a right-of-use right-of-use Right-of-use right-of-use right-of-use right-of-use The right-of-use The Company applies IAS 36 to determine whether a right-of-use Variable rents that do not depend on an index or rate are not included in the measurement the lease liability and the right-of-use As a practical expedient, IFRS 16 Leases (“IFRS 16”) permits a lessee not to separate non-lease non-lease
Restoration provisions		(w) Restoration provisions Provisions for the costs to restore leased plant assets to their original condition, as required by the terms and conditions of the lease, are recognised when the obligation is incurred, either at the commencement date or as a consequence of having used the underlying asset during a particular period of the lease, at the directors’ best estimate of the expenditure that would be required to restore the assets. Estimates are regularly reviewed and adjusted as appropriate for new circumstances. Whenever the Company incurs an obligation for costs to dismantle and remove a leased asset, restore the site on which it is located or restore the underlying asset to the condition required by the terms and conditions of the lease, a provision is recognised and measured under IAS 37. To the extent that the costs relate to a right-of-use right-of-use
