Incorporation and nature of business
Incorporation and nature of business	1. Incorporation and nature of business Vision Marine Technologies Inc. [the “Company”] was incorporated on August 29, 2012 and its principal business is to manufacture and sell or rent electric boats. The Voting Common Shares of the Company are listed under the trading symbol “VMAR” on Nasdaq. The Company is incorporated in Canada and its head office and registered office is located at 730 Curé-Boivin boulevard, Boisbriand, Quebec, J7G 2A7. Business seasonality The Company’s operating results generally vary from quarter to quarter as a result of changes in general economic conditions and seasonal fluctuations, among other things, in each of its reportable segments. This means the Company’s results in one quarter are not necessarily indicative of how the Company will perform in a future quarter. Sale of electric boats The sale of electric boats segment has a seasonal aspect to its operations. Most customers purchase their electric boats from the Company with the intention of utilizing them during the summer period which typically runs from early June to late August and corresponds to the Company’s fourth quarter of a financial year. As such, the revenues in this operating segment fluctuates based on the level of boat deliveries, with a high and a low in the fourth quarter and the first quarter, respectively. Rental of electric boats Revenue generated by the rental of electric boats segment also has a seasonal aspect to its operations. Boat rental as an activity is highly sought by customers when the weather is milder, which is typically the case during the period from May to August. A colder-than-expected or rainier summer in any given year could have an impact on the segment’s revenues and hence on its profitability. Revenue from the boat club memberships is not impacted by seasonality as the memberships are typically on an annual basis.	1. Incorporation and nature of business Vision Marine Technologies Inc.

Significant accounting policies
Significant accounting policies	3. Significant accounting policies Business combination Business combinations are accounted for using the acquisition method when the acquired set of activities and assets meets the definition of a business and control is transferred to the Company. In determining whether a particular set of activities and assets is a business, the Company assesses whether the set of assets and activities acquired includes, at a minimum, an input and substantive process and whether the acquired set has the ability to produce outputs. The Company has an option to apply a ‘concentration test’ that permits a simplified assessment of whether an acquired set of activities and assets is not a business. The optional concentration test is met if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. The consideration transferred in the acquisition is measured at fair value at the acquisition date, as are the identifiable net assets acquired. The Company assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. Subsequent adjustments to the fair values of identifiable net assets acquired are adjusted against the consideration transferred when they qualify as measurement period adjustments. Transaction costs are expensed as incurred. ​ Cash and cash equivalents Cash and cash equivalents include cash in hand, cash held in trust, deposits held at call with banks, other short term highly liquid investments with original maturities of three months or less, and – for the purpose of the statement of cash flows – bank overdrafts. Bank overdrafts are shown within bank indebtedness in current liabilities on the consolidated statement of financial position. Trade and other receivables Trade receivables are initially recognized at fair value and subsequently measured at amortized cost using the effective interest method, less any allowance for expected credit losses. Trade receivables are generally due for settlement within 30 days. The Company has applied the simplified approach to measuring expected credit losses, which uses a lifetime expected loss allowance. To measure the expected credit loss, trade receivables have been grouped based on days overdue. Other receivables are recognized at amortized cost, less any allowance for expected credit loss. Inventories Inventories are stated at the lower of cost and net realizable value. Raw materials are valued on a first-in first-out basis. Cost of work in progress and finished goods comprises direct materials and delivery costs, direct labour, import duties and other taxes, and appropriate proportion of variable and fixed overhead expenditure based on normal operating capacity. Cost of purchased inventory are determined after deducted rebates and discounts received or receivable. Net realizable value is the estimated selling price in the ordinary course of business less estimated costs of completion and the estimated costs necessary to make the sale. Grants and investment tax credits Government grants are recognized where there is reasonable assurance that the grant will be received, and all attached conditions will be complied with. When the grant relates to an expense item, it is recognized as income on a systematic basis over the periods that the related costs, for which it is intended to compensate, are expensed. Where retention of a government grant is dependent on the Company satisfying certain criteria, it is initially recognized as deferred income. When the criteria for retention have been satisfied, the deferred income balance is released to the statement of consolidated comprehensive loss or netted against the asset purchased. Leases Right-of-use assets The Company recognizes right-of-use assets at the commencement date of the lease [i.e., the date the underlying asset is available for use]. Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognized, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Unless the Company is reasonably certain to obtain ownership of the leased asset at the end of the lease term, the recognized right-of-use assets are depreciated on a straight-line basis over the shorter of its estimated useful life and the lease term ranging from two Lease liabilities At the commencement date of the lease, the Company recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments [including in-substance fixed payments] less any lease incentives receivable and variable lease payments that depend on an index or a rate. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Company and payments of penalties for terminating a lease, if the lease term reflects the Company exercising the option to terminate. The variable lease payments that do not depend on an index or a rate are recognized as expense in the period on which the event or condition that triggers the payment occurs. In calculating the present value of lease payments, the Company uses the incremental borrowing rate at the lease commencement date if the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. Interest accretion is recorded as interest expense in finance costs. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the in-substance fixed lease payments or a change in the assessment to purchase the underlying asset. Short-term leases and leases of low-value assets The Company applies the short-term lease recognition exemption to its short-term leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option. It also applies the lease of low-value assets recognition exemption to leases of office equipment that are considered of low value [i.e., below $5,000]. Lease payments on short-term leases and leases of low-value assets are recognized as expense on a straight-line basis over the lease term. For the year-ended August 31, 2022, the expense for leases of low-value assets is insignificant. Property and equipment Property and equipment is stated at cost less accumulated depreciation and accumulated impairment losses, if any. Cost includes expenditures that are directly attributable to the acquisition of the asset. Depreciation is recorded to recognize the cost of assets over their useful lives. The estimated useful lives and depreciation methods are reviewed at the end of each reporting period, with the effect of any changes in estimate accounted for on a prospective basis. ​ Asset type Methods Rates Computer equipment Declining balance method 55% Machinery and equipment Declining balance method 20% Rolling stock Declining balance method 30% Leasehold improvements Straight-line method Over the term of the lease Boat rental fleet Straight-line method 15 years Moulds Straight-line method 25 years ​ Any item of property and equipment is derecognized 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 the disposal or retirement of an asset is determined as the difference between the sales and proceeds and the carrying amount of the asset and is recognized in profit or loss. Repairs and maintenance costs that do not improve or extend productive life are recognized in profit or loss in the period in which the costs are incurred. Intangible assets and goodwill Expenditure on research activities is recognized in net earnings as incurred. Development expenditure is capitalized only if the expenditure can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable and the Company intends to and has sufficient resources to complete development and to use or sell the asset. Otherwise, it is recognized in net earnings as incurred. The Company has not capitalized any development costs. When awarded with government grants and income tax credits, the Company recognizes the income either in net income (loss), netted with the related expenses, or as a reduction of the cost, when related with capitalized development expenditure. Goodwill arising from business combinations is initially recognized when the fair value of the separately identifiable assets the Company acquired and liabilities the Company assumed is lower than the consideration paid [including the recognized amount of the non-controlling interest, if any]. If the fair value of the consideration transferred is lower than that of the separately identified assets and liabilities, the Company immediately recognizes the difference as a gain in the consolidated statement of comprehensive loss. Other intangible assets, including intellectual property, software, trade name, backlog and website that have finite useful lives are measured at cost less accumulated amortization and accumulated impairment losses. Amortization is calculated over the cost of the asset less its residual value. Amortization is recognized in net earnings on a straight-line basis over the estimated useful lives of intangible assets from the date that they are available for use. The estimated useful lives are as follows: ​ Asset type Methods Rates Intellectual property Straight-line method 10 years Software Straight-line method 7 years Trade name Straight-line method 5 years Backlog Straight-line method 3 years Website Straight-line method 5 years ​ Amortization methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate. Impairment of non-financial assets Non-financial assets other than goodwill At the end of each reporting period, the Company reviews the carrying amounts of its non-financial assets, other than goodwill, to determine whether there is any indication of impairment. If any such indication exists, the recoverable amount of the asset is estimated. Where it is not possible to estimate the recoverable amount of an individual asset, assets are grouped together into the smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or groups of assets [the “cash-generating unit”, or “CGU”]. Recoverable amount is the greater 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 discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or CGU. If the recoverable amount of an asset or CGU is lower than its carrying amount, the carrying amount is reduced to its recoverable amount. An impairment loss is recognized immediately in the consolidated statement of comprehensive loss. Where an impairment loss subsequently reverses, the carrying amount of the asset or CGU is increased to the revised recoverable amount, to the extent that the carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized. A reversal of an impairment loss is recognized immediately in the consolidated statement of comprehensive loss. Goodwill After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For purposes of impairment testing, goodwill is allocated to each of the Company’s CGU [or groups of CGUs] that is expected to benefit from the synergies of the combination. A CGU to which goodwill has been allocated is tested for impairment annually, or more frequently when there is indication that the CGU may be impaired. If the recoverable amount of the CGU is less than its carrying amount, the impairment loss is allocated first to reduce the goodwill allocated to the CGU and then, to reduce the carrying amounts of the other assets in the CGU on a pro-rata basis. Any impairment loss is recognized in the consolidated statement of comprehensive loss. An impairment loss recognized for goodwill is not reversed in subsequent periods. Trade and other payables These amounts represent liabilities for goods and services provided to the entity prior to the end of the financial year and which are unpaid. Due to their short-term nature, they are measured at amortized cost and are not discounted. The amounts are unsecured and are usually paid within 30 days of recognition. Provisions Provisions are recognized when the Company has a present obligation as a result of a past event, it is probable the Company will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the reporting date, taking into account the risks and uncertainties surrounding the obligation. If the time value money is material, provisions are discounted using a current pre-tax rate specific to the liability. The increase in the provision resulting from the passage of time is recognized as a finance cost. Fair value measurement When an asset or liability, financial or non-financial, is measured at fair value for recognition or disclosure purposes, the fair value is based on 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; and assumes that the transaction will take place either: in the principal market; or in the absence of a principal market, in the most advantageous market. Fair value is measured using the assumptions that market participants would use when pricing the asset or liability, assuming they act in their economic best interests. For non-financial assets, the fair value measurement is based on its highest and best use. Valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, are used, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. Assets and liabilities measured at fair value are classified into three levels, using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. Classifications are reviewed at each reporting date and transfers between levels are determined based on a reassessment of the lowest level of input that is significant to the fair value measurement. Financial instruments Classification and measurement of financial instruments The Company measures its financial assets and financial liabilities at fair value on initial recognition, which is typically the transaction price unless a financial instrument contains a significant financing component. Subsequent measurement is dependent on the financial instrument’s classification which in the case of financial assets, is determined by the context of the Company’s business model and the contractual cash flow characteristics of the financial asset. Financial assets are classified into two categories: [1] measured at amortized cost and [2] fair value through profit and loss [“FVTPL”]. Financial liabilities are subsequently measured at amortized cost at the effective interest rate, other than financial liabilities that are measured at FVTPL or designated as FVTPL where any change in fair value resulting from an entity’s own credit risk is recorded as other comprehensive income [“OCI”]. Amortized cost The Company classifies trade and other receivables, other financial assets, trade and other payables, other financial liabilities, long-term debt and advances to/from related parties as financial instruments measured at amortized cost. The contractual cash flows received from the financial assets are solely payments of principal and interest and are held within a business model whose objective is to collect the contractual cash flows. Fair value through profit and loss The Company classifies debentures as financial instruments measured at fair value through profit and loss since the contractual cash flows received from the financial asset are not solely payments of principal and interest. Impairment of financial assets The Company recognizes a loss allowance for expected credit losses on financial assets measured at amortized cost. The measurement of the loss allowance depends upon the Company’s assessment at the end of each reporting period as to whether the financial instrument’s credit risk has increased significantly since initial recognition, based on reasonable and supportable information that is available, without undue cost or effort to obtain. Where there has not been a significant increase in exposure to credit risk, a 12-month expected credit loss allowance is estimated. The amount of expected credit loss recognized is measured on the basis of the probability weighted present value of anticipated cash shortfalls over the life of the instrument discounted at the original effective interest rate. Impairment provisions for current and non-current trade receivables are recognized based on the simplified approach within IFRS 9 using a provision matrix in the determination of the lifetime expected credit losses. Equity instruments Financial instruments issued by the Company are classified as equity only to the extent that they do not meet the definition of a financial liability or financial asset. An equity instrument is any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities. Equity instruments issued by the Company are recorded at the proceeds received, net of direct issuance costs. The Company’s shares are classified as equity instruments. Revenue recognition Revenue is recognized at an amount that reflects the consideration to which the Company is expected to be entitled in exchange for transferring goods or services to a customer. For each contract with a customer, the Company: ● identifies the contract with the customer; ● identifies the performance obligations in the contract; ● determines the transaction price which takes into account estimates of variable consideration and the time value of money; ● allocates the transaction price to separate performance obligations on the basis of relative stand-alone selling price of each distinct good or service to be delivered; and, ● recognizes revenue when or as each performance obligation is satisfied in a manner that depicts the transfer to the customer of the goods or services promised. The Company enters into contracts with customers, as well as distributor agreements with specific distributors for the sale of boats. Sale of boats Revenue from the sale of boats, including incidental shipping fees, is recognized at the point in time when the customer obtains control of the goods, which is generally at the shipping point. In the context of its distributor agreements, control is passed at the shipping point to the distributor as the Company has no further performance obligations at that point. The Company concluded that it is the principal in its revenue arrangements, because it typically controls the boats before transferring them to the customer. The amount of consideration the Company receives, and the revenue recognized varies with volume rebate programs offered to distributors. When the Company offers retrospective volume rebates, it estimates the expected volume rebates based on an analysis of historical experience, to the extent that it is highly probable that a significant reversal will not occur. The Company adjusts its estimate of revenue related to volume rebates at the earlier of when the most likely amount of consideration expected to be received changes or when the consideration becomes fixed. The Company recognizes customer deposits on the sale of boats as contract liabilities. Boat rental and boat club membership revenue Revenue from boat rentals is recognized at a point in time when the services are completed. Boat club membership revenue is recognized over time as the service is provided. These services are typically provided, and thus revenue is typically recognized, on a monthly basis. The Company recognizes customer prepayments on boat rentals and boat club memberships as contract liabilities. Sale of parts and boat maintenance Revenue from the sale of parts and related maintenance services are recognized at the point in time when the customer obtains control of the parts and when services are completed. Other Other revenue is recognized when it is received or when the right to receive payment is established. Contract liabilities A contract liability is recognized if a payment is received, or a payment is due [whichever is earlier] from a customer before the Company transfers the related goods or services. Contract liabilities are recognized as revenue when the Company performs under the contract [i.e., transfers control of the related goods or services to the customer]. Share-based payments The Company has a share option plan for key employees, consultants, advisors, officers and directors from which options to purchase common stock of the Company are issued. The Company also issues warrants to non-employees granting the right to purchase common stock of the Company at a determined exercise price . All share-based remuneration is ultimately recognized as an expense in profit or loss with a corresponding credit to contributed surplus. If vesting periods or other vesting conditions apply, the expense is allocated over the vesting period, based on the best available estimate of the number of share options expected to vest. Any adjustment to cumulative share-based compensation resulting from a revision is recognized in the current period. The number of vested options ultimately exercised by holders does not impact the expense recorded in any period. Foreign currency translation The Company’s consolidated financial statements are presented in Canadian dollars, which is also the parent company’s functional currency. The functional currencies of 7858078 Canada Inc. and EB Rental Ltd. are the Canadian dollar and the US dollar, respectively. The Company and its subsidiaries each determine their functional currency based on the currency of the primary economic environment in which they operate. Transactions denominated in a currency other than the functional currency of an entity are translated at the exchange rate in effect on the transaction date. The resulting exchange gains and losses are included in each entity’s net income (loss) in the period in which they arise. The Company’s foreign operations are translated to the Company’s presentation currency, for inclusion in the consolidated financial statements. Foreign-denominated monetary and non-monetary assets and liabilities of foreign operations are translated at exchange rates in effect at the end of the reporting period and revenue and expenses are translated at exchange rates in effect at the transaction date. The resulting translation gains and losses are included in other comprehensive loss with the cumulative gain or loss reported in accumulated other comprehensive income. On disposal of a foreign operation, the component of OCI relating to that particular foreign operation is reclassified to profit or loss. The exchange rates for the currencies used in the preparation of the consolidated financial statements were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Exchange rate as at ​ Average exchange rate for year ended ​ August 31, August 31, August 31, August 31, ​ ​ 2022 ​ 2021 ​ 2022 ​ 2021 US dollar 1.3076 1.2630 1.2717 1.2688 ​ Taxes Tax expense comprises current and deferred tax. Tax is recognized in net income (loss) except to the extent it relates to items recognized in other comprehensive income or directly in equity. Current tax Current tax expense is based on the results for the period as adjusted for items that are not taxable or not deductible. Current tax is calculated using tax rates and laws that were enacted or substantively enacted at the end of the reporting period. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. Deferred tax Deferred taxes are the taxes expected to be payable or recoverable on differences between the carrying amounts of assets in the statement of financial position and their corresponding tax bases used in the computation of taxable profit. Deferred tax liabilities are generally recognized for all taxable temporary differences between the carrying amounts of assets and their corresponding tax bases. Deferred tax assets are recognized to the extent that it is probable that taxable profits will be available against which deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized. Such assets and liabilities are not recognized if the temporary difference arises from the initial recognition of goodwill or from the initial recognition [other than in a business combination] of other assets in a transaction that affects neither the taxable profit nor the accounting profit. The Company offsets deferred tax assets and deferred tax liabilities if and only if it has a legally enforceable right to set off current tax assets and current tax liabilities and the deferred tax assets and deferred tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered. Earnings per share Basic earnings per share is calculated by dividing the profit or loss attributable to equity holders of the Company by the weighted average number of common stock outstanding during the year. Diluted income per share is calculated by dividing the profit attributable to equity holders of the Company by the weighted average number of common stock outstanding, adjusted for the effects of all dilutive potential common stock. The weighted average number of common stock outstanding is increased by the number of additional common stock that would have been issued by the Company assuming exercise of all options with exercise prices below the average market price for the year. Standards issued but yet not effective The new and amended standards and interpretations that are issued, but not yet effective, up to the date of issuance of the Company’s financial statements are disclosed below. The Company intends to adopt these new and amended standards and interpretations, if applicable, when they become effective. Onerous Contracts – Costs of Fulfilling a Contract – Amendments to IAS 37 In May 2020, the IASB issued amendments to IAS 37 to specify which costs an entity needs to include when assessing whether a contract is onerous or loss-making. The amendments apply a “directly related cost approach”. The costs that relate directly to a contract to provide goods or services include both incremental costs and an allocation of costs directly related to contract activities. General and administrative costs do not relate directly to a contract and are excluded unless they are explicitly chargeable to the counterparty under the contract. The amendments are effective for annual reporting periods beginning on or after January 1, 2022. The amendments are not expected to have a material impact on the Company’s consolidated financial statements. Property, Plant and Equipment: Proceeds before Intended Use – Amendments to IAS 16 Property, plant and equipment The amendment prohibits entities from deducting from the cost of an item of property, plant and equipment, any proceeds of the sale of items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognizes the proceeds from selling such items, and the costs of producing those items, in profit or loss. The amendment is effective for annual reporting periods beginning on or after January 1, 2022 and must be applied retrospectively to items of property, plant and equipment made available for use on or after the beginning of the earliest period presented when the entity first applies the amendment. The amendments are not expected to have a material impact on the Company’s consolidated financial statements.

Significant accounting estimates and assumptions
Significant accounting estimates and assumptions	4. Significant accounting estimates and assumptions The preparation of financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and contingent liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Estimates and judgments are continuously evaluated and are based on management’s experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Actual outcomes can differ from these estimates. Business acquisition fair value The Company makes a number of estimates when determining the acquisition date fair values of consideration transferred, assets acquired, and liabilities assumed in a business acquisition. Fair values are estimated using valuation techniques based on discounted future cash flows. Future cash flows may be influenced by a number of assumptions such as forecasted revenues, royalty rate, selling prices, costs to operate, capital expenditures, growth rate and the discount rate. Impairment of non-financial assets Impairment exists when the carrying value of an asset or cash generating unit exceeds its recoverable amount, which is the higher of its fair value less costs of disposal and its value in use. The Company concluded the fair value less costs of disposal will yield a higher recoverable amount, which is based on a discounted cash flow (“DCF”) model. The fair value measurement is categorized within Level 3 of the fair value hierarchy. The cash flows are derived from cash flow projections over a 5-year period, including future investments and expansion activities that will enhance the performance of the assets of the CGU. As at August 31, 2021, all of the Company’s goodwill is allocated to the boat rental operation CGU, which represents the lowest level within the Company at which the goodwill is monitored for internal management purposes. For the year ended August 31, 2022, there was no impairment of goodwill. The recoverable amount is sensitive to the discount rate used for the DCF model, as well as the expected future cash-inflows, gross profit and the growth rate used for extrapolation purposes. The post-tax discount rate of 27% used in the DCF is based on a weighted average cost of capital calculated using observable market-based inputs or a benchmark of a sample of representative publicly traded companies. The long-term growth rate of 2% used for extrapolation purposes is based on published research growth rates. Any reasonable negative change in the key assumptions used could cause the carrying value of this CGU to exceed its recoverable amount. Financial instruments measured at fair value In measuring financial instruments at fair value, the Company makes estimates and assumptions, including estimates and assumptions about interest rates, credit spreads and other market conditions. Provision for impairment of inventories The provision for impairment of inventories assessment requires a degree of estimation and judgment. The level of the provision is assessed by taking into account the recent sales experience, the ageing of inventories and other factors that affect inventory obsolescence. Income tax Provisions for taxes are made using the best estimate of the amount expected to be paid based on a qualitative assessment of all relevant factors. The Company reviews the adequacy of these provisions at the end of the reporting period. However, it is possible that at some future date an additional liability could result from audits by taxing authorities. Where the final outcome of these tax-related matters is different from the amounts that were initially recorded, such differences will affect the tax provisions in the period in which such determination is made. The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are re-assessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered. In assessing the recoverability of deferred tax assets, the Company relies on the same forecast assumptions used elsewhere in the financial statements and in other management reports, which, among other things, reflect the potential impact of climate-related development on the business. Share-based payments The Company measures the cost of equity-settled transactions with employees by reference to the fair value of the equity instrument at the date at which they are granted. The fair value is determined by using the Black-Scholes model taking into account the terms and conditions upon which the instruments were granted. Judgment is exercised in determining the expected life and historical volatility. The accounting estimates and assumptions relating to equity-settled share-based payments would have no impact on the carrying amounts of assets and liabilities but may impact profit or loss and equity. Lease term The lease term is a significant component in the measurement of both the right-of-use asset and lease liability. Judgment is exercised in determining whether there is reasonable certainty that an option to extend the lease will be exercised, when ascertaining the periods to be included in the lease term. In determining the lease term, all facts and circumstances that create an economical incentive to exercise an extension option are considered at the lease commencement date. The Company reassesses whether it is reasonably certain to exercise an extension option if there is a significant event or significant change in circumstances. Incremental borrowing rate Where the interest rate implicit in the lease cannot be readily determined, an incremental borrowing rate is estimated to discount future lease payments to measure the present value of the lease liability at the lease commencement date. Such a rate is based on what the Company estimates it would have to pay a third party to borrow the funds necessary to obtain an asset of a similar value to the right-of-use asset, with similar terms, security and economic environment.

Business combination	5. Business combination On June 3, 2021, the Company completed the acquisition of EB Rental Ltd. [“EBR”] by acquiring all the issued and outstanding EBR was acquired for cash consideration of U.S.$4,582,367 ($5,546,039), financed entirely by the Company’s available cash on hand, and equity consideration of $3,474,232 representing 284,495 shares at U.S.$10.09 [approximately $12.21] per share [note 18] The acquisition gave rise to transaction costs of $13,170 which were expensed as incurred in the consolidated statements of comprehensive loss. The investment was accounted for as a business combination and the results have been included in the consolidated statements of comprehensive loss since the date of the acquisition. The revenues and net earnings included in the consolidated statements of comprehensive loss are approximately $1,360,000 and $530,000 respectively for the 90-day period ended August 31, 2021. The following table reflects the recognized amounts of assets acquired and liabilities assumed, on a fair value basis, at the acquisition date: ​ ​ ​ ​ ​ June 3, 2021 ​ ​ $ Fair value at acquisition ​ Cash ​ 516,623 Trade and other receivables ​ 7,998 Income tax receivable ​ 9,963 Inventories ​ 12,864 Prepaids ​ 34,687 Advances to related parties ​ 177,671 Other financial assets ​ 7,685 Right-of-use asset ​ 1,651,746 Property and equipment ​ 417,554 Intangible assets ​ 184,000 Deferred tax asset ​ 18,467 Goodwill ​ 8,656,700 Trade and other payables ​ (111,602) Income tax payable ​ (1,952) Contract liabilities ​ (482,173) Other financial liabilities ​ (242,060) Long-term debt, including current portion ​ (66,204) Lease liability, including current portion ​ (1,651,746) Deferred tax liability ​ (119,950) Net assets acquired ​ 9,020,271 ​ The Company measured the acquired lease liabilities using the present value of the remaining lease payments at the date of acquisition. The right-of-use assets were measured at an amount equal to the lease liabilities and adjusted to reflect the favorable terms of the lease relative to market terms, if any. The fair value of the intangible assets, which consist in trade name, backlog and website, was calculated using a discounted cash flow approach. The fair value of property and equipment was established using a market value approach. The goodwill related to the acquisition of EBR arises from the benefits of increasing our strategic position by expanding our market presence, expected synergies and integrating an assembled workforce that does not qualify for separate recognition. The goodwill is not deductible for tax purposes. The balance of goodwill is at $9,352,640 at August 31, 2022 [2021 – $9,033,638], with the change since acquisition date due to foreign exchange translation.

Debentures	5. Debentures On May 14, 2021, the Company subscribed for and purchased 3,400 senior unsecured subordinated convertible debentures of The Limestone Boat Company Limited [“Limestone”], a publicly traded company listed under the trading symbol "BOAT" on the TSX Venture Exchange [the "Debentures"], for an aggregate amount of $3,400,000. The Debentures bear interest at a rate of 10% per annum, payable annually in arrears, and have a 36-month term [the “Term”]. The Debentures are convertible at any time at the option of the Company into common shares of Limestone [“Common Shares”] at a conversion price of $0.36 per Common Share [the “Conversion Price”]. If at any time following 120 days from the date of issuance of the Debentures [the “Closing Date“] and prior to the date that is 30 days prior to the end of the Term, the volume weighted average closing price of the Common Shares on the TSX Venture Exchange, or such other exchange on which the Common Shares may be listed, is equal to or higher than $0.50 per Common Share for 20 consecutive trading days, Limestone may notify the Company that the Debentures will be automatically converted into Common Shares at the Conversion Price 30 days following the date of such notice. The Debentures are carried at fair value through profit and loss and are considered as Level 2 financial instruments in the fair value hierarchy. On January 20, 2023, Limestone announced that Limestone’s U.S. subsidiaries filed a Chapter 7 of the Bankruptcy Code in the U.S. As a result, the Company recorded an impairment on the entire value of the Debentures at the amount of nil and $2,637,000 in the three and nine months ended May 31, 2023 [May 31, 2022 – nil]. For the three and nine months ended May 31, 2023, the Company recorded a loss of nil and $109,667 respectively [May 31, 2022 – $115,000 and $436,500 respectively] in net finance expense for change in the fair value of the Debentures [ note 19	8. Debentures On May 14, 2021, the Company subscribed for and purchased 3,400 senior unsecured subordinated convertible debentures of The Limestone Boat Company Limited [“Limestone”], a publicly traded company listed under the trading symbol "BOAT" on the TSX Venture Exchange [the "Debentures"], for an aggregate amount of $3,400,000. The Debentures bear interest at a rate of 10% per annum, payable annually in arrears, and have a 36-month term [the “Term”]. The Debentures are convertible at any time at the option of the Company into common shares of Limestone [“Common Shares”] at a conversion price of $0.36 per Common Share [the “Conversion Price”]. If at any time following 120 days from the date of issuance of the Debentures [the “Closing Date“] and prior to the date that is 30 days prior to the end of the Term, the volume weighted average closing price of the Common Shares on the TSX Venture Exchange, or such other exchange on which the Common Shares may be listed, is equal to or higher than $0.50 per Common Share for 20 The Debentures are carried at fair value through profit and loss and are considered as Level 2 financial instruments in the fair value hierarchy. For the year ended August 31, 2022, the Company recorded a loss of $670,000 [2021 - $550,000; 2020 - Nil] for the change in fair value of the Debentures and interest income of $340,000 [2021 - $85,000; 2020 - Nil] in net income (loss) as a net financial expense. Subsequent to year end, Limestone announced that it has implemented significant cost savings measures, as well as the withdrawal of its previously proposed debt financings. As Limestone continues to pursue alternative liquidity and financing proposals, these factors may have a negative impact on the key assumptions described in Note 25 used by the Company to determine the fair value of the Debentures subsequent to the reporting date. Although the estimates of the fair value of the Debentures as at August 31, 2022 are based on management’s best knowledge and estimates of the amount, events or actions at that time, the valuation in future periods ultimately may differ from those estimates.

The Company assessed the classification of the compound financial instrument issued, whether the warrants issued meet the criteria of an equity instrument (i.e. the warrants would be settled by the issuance of fixed number of common shares of the Company at a fixed exercise price) or a financial liability. Since the exercise price of these warrants is denominated in U.S. dollar, while the functional currency of the Company is Canadian dollar, the value of the proceeds on exercise of the warrants is not fixed and will vary based on the foreign exchange rate movements. As such, the Company classified the warrants, other than warrants issued as compensation for goods and services, as derivative liabilities, measured at fair value at initial recognition and at each reporting period. Refer to note 16 for details on the assumptions used to determine the fair value. Any changes in fair value are recorded as gain or loss in the consolidated statement of comprehensive loss. At issuance and as at May 31, 2023, the derivative liabilities amounted to $4,866,082 and $3,253,024, respectively [August 31, 2022 – Nil], with the allocated transaction costs of $489,096 recorded in net finance expense [note 19]	18.

Capital disclosures	24. Capital disclosures The Company’s objectives in managing capital are: ● ● ​ Capital is regarded as total equity, as recognized in the statement of financial position, plus net debt. Net debt is calculated as total borrowings less cash and cash equivalents. The Company manages and adjusts its capital structure considering changes in economic conditions. To maintain or adjust its capital structure, the Company may issue debt or new shares. Financing decisions are generally made on a specific transaction basis and depend on such things as the Company’s needs, capital markets and economic conditions at the time of the transaction. Management reviews its capital management approach on an ongoing basis and believes that this approach is reasonable, given the size of the Company. The Company does not have any externally imposed capital compliance requirements at August 31, 2022.

Financial risk management and fair value measurement
Financial risk management and fair value measurement	25. Financial risk management and fair value measurement Fair value measurement and hierarchy The fair value measurement of the Company’s financial and non-financial assets and liabilities utilizes market observable inputs and data as far as possible. Inputs used in determining fair value measurements are categorized into different levels based on how observable the inputs used in the valuation technique utilized are (the “fair value hierarchy”): ● Level 1: Quoted prices in active markets for identical items [unadjusted]; ● Level 2: Observable direct or indirect inputs other than Level 1 inputs; and ● Level 3: Unobservable inputs [i.e., not derived from market data]. ​ The classification of an item into the above levels is based on the lowest level of the inputs used that has a significant effect on the fair value measurement of the item. Transfers of items between levels are recognized in the period they occur. The carrying amount of trade and other receivables, advances from related parties and trade and other payables are assumed to approximate their fair value due to their short-term nature. The fair value of financial liabilities is estimated by discounting the remaining contractual maturities at the current market interest rate that is available for similar financial liabilities. Classified as Level 2, the fair value of Debentures is estimated using the partial differential equation model to value convertible debentures that include a call feature. Key assumptions used in the model include volatility, which is based on actual trading data, difference in volatility since initial issuance of the instrument and similar instruments on the market, and credit spread, which is based on corporate bond yield spreads in the market and credit spread data for similar public companies. The model includes a fair value adjustment based on an initial calibration exercise. Below is a sensitivity analysis based on variations in the key assumptions used in the model. The table presents the fair value of the Debentures would have been had the key assumptions varied as indicated: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Volatility ​ Credit spread ​ ​ + 5 % ​ -5% ​ + 2 % ​ -2% ​ $ $ $ $ Fair value of debentures 2,441,000 2,431,500 2,382,000 2,490,500 ​ Financial risk management The Company is exposed to risks that arise from its use of financial instruments. This note describes the Company’s objectives, policies and processes for managing those risks and the methods used to measure them. [a] Credit risk Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in financial loss to the Company. The Company has a strict code of credit, including obtaining instalment payments, obtaining agency credit information and setting appropriate credit limits. The maximum exposure to credit risk at the reporting date, is the carrying amount of financial assets. The Company does not hold any collateral. Credit risk related with the Debentures is reflected in the fair value of the instrument [note 8] Trade and other receivables are generally written off when there is no reasonable expectation of recovery. Indicators of this include the failure for a debtor to engage in a repayment plan, no active enforcement activity and a failure to make contractual payments. [b] Liquidity risk Liquidity risk is the risk that the Company will encounter difficulty in meeting its financial obligations as they fall due. The Company is exposed to liquidity risk primarily from its trade and other payables, other financial liabilities and long-term debt. The Company believes that its recurring financial resources are adequate to cover all its expenditures. ​ ​ ​ ​ ​ ​ ​ ​ ​ Contractual ​ Less than ​ ​ ​ ​ cash flows ​ one year ​ 1-5 years ​ $ $ $ August 31, 2022 ​ Trade and other payables ​ 1,030,331 1,030,331 — Other financial liabilities ​ 177,834 177,834 — Long-term debt ​ 227,349 72,090 155,259 ​ ​ 1,435,514 1,280,255 155,259 ​ ​ ​ ​ ​ ​ ​ August 31, 2021 ​ Trade and other payables ​ 848,054 848,054 — Other financial liabilities ​ 237,444 237,444 — Long-term debt ​ 64,115 10,179 53,936 ​ ​ 1,149,613 1,095,677 53,936 ​ [c] Interest rate risk The Company is exposed to interest rate risk on its variable rate bank indebtedness and variable and fixed rate long-term debt. Fixed-rate borrowings expose the Company to fair value risk while variable rate borrowings expose the Company to cash flow risk. [d] Foreign exchange risk Foreign exchange risk is the risk that future cash flows or fair value of a financial instrument will fluctuate due to changes in foreign exchange rates. The Company is exposed to transactional foreign currency risk to the extent that there is a mismatch between the currencies in which sales, purchases, receivables and borrowings are denominated and the respective functional currencies of the Company and its subsidiaries.

Significant accounting policies
Business combination	Business combination Business combinations are accounted for using the acquisition method when the acquired set of activities and assets meets the definition of a business and control is transferred to the Company. In determining whether a particular set of activities and assets is a business, the Company assesses whether the set of assets and activities acquired includes, at a minimum, an input and substantive process and whether the acquired set has the ability to produce outputs. The Company has an option to apply a ‘concentration test’ that permits a simplified assessment of whether an acquired set of activities and assets is not a business. The optional concentration test is met if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. The consideration transferred in the acquisition is measured at fair value at the acquisition date, as are the identifiable net assets acquired. The Company assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. Subsequent adjustments to the fair values of identifiable net assets acquired are adjusted against the consideration transferred when they qualify as measurement period adjustments. Transaction costs are expensed as incurred.
Cash and cash equivalents	Cash and cash equivalents Cash and cash equivalents include cash in hand, cash held in trust, deposits held at call with banks, other short term highly liquid investments with original maturities of three months or less, and – for the purpose of the statement of cash flows – bank overdrafts. Bank overdrafts are shown within bank indebtedness in current liabilities on the consolidated statement of financial position.
Trade and other receivables	Trade and other receivables Trade receivables are initially recognized at fair value and subsequently measured at amortized cost using the effective interest method, less any allowance for expected credit losses. Trade receivables are generally due for settlement within 30 days. The Company has applied the simplified approach to measuring expected credit losses, which uses a lifetime expected loss allowance. To measure the expected credit loss, trade receivables have been grouped based on days overdue. Other receivables are recognized at amortized cost, less any allowance for expected credit loss.
Inventories	Inventories Inventories are stated at the lower of cost and net realizable value. Raw materials are valued on a first-in first-out basis. Cost of work in progress and finished goods comprises direct materials and delivery costs, direct labour, import duties and other taxes, and appropriate proportion of variable and fixed overhead expenditure based on normal operating capacity. Cost of purchased inventory are determined after deducted rebates and discounts received or receivable. Net realizable value is the estimated selling price in the ordinary course of business less estimated costs of completion and the estimated costs necessary to make the sale.
Grants and investment tax credits	Grants and investment tax credits Government grants are recognized where there is reasonable assurance that the grant will be received, and all attached conditions will be complied with. When the grant relates to an expense item, it is recognized as income on a systematic basis over the periods that the related costs, for which it is intended to compensate, are expensed. Where retention of a government grant is dependent on the Company satisfying certain criteria, it is initially recognized as deferred income. When the criteria for retention have been satisfied, the deferred income balance is released to the statement of consolidated comprehensive loss or netted against the asset purchased.
Leases	Leases Right-of-use assets The Company recognizes right-of-use assets at the commencement date of the lease [i.e., the date the underlying asset is available for use]. Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognized, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Unless the Company is reasonably certain to obtain ownership of the leased asset at the end of the lease term, the recognized right-of-use assets are depreciated on a straight-line basis over the shorter of its estimated useful life and the lease term ranging from two Lease liabilities At the commencement date of the lease, the Company recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments [including in-substance fixed payments] less any lease incentives receivable and variable lease payments that depend on an index or a rate. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Company and payments of penalties for terminating a lease, if the lease term reflects the Company exercising the option to terminate. The variable lease payments that do not depend on an index or a rate are recognized as expense in the period on which the event or condition that triggers the payment occurs. In calculating the present value of lease payments, the Company uses the incremental borrowing rate at the lease commencement date if the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. Interest accretion is recorded as interest expense in finance costs. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the in-substance fixed lease payments or a change in the assessment to purchase the underlying asset. Short-term leases and leases of low-value assets The Company applies the short-term lease recognition exemption to its short-term leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option. It also applies the lease of low-value assets recognition exemption to leases of office equipment that are considered of low value [i.e., below $5,000]. Lease payments on short-term leases and leases of low-value assets are recognized as expense on a straight-line basis over the lease term. For the year-ended August 31, 2022, the expense for leases of low-value assets is insignificant.
Property and equipment	Property and equipment Property and equipment is stated at cost less accumulated depreciation and accumulated impairment losses, if any. Cost includes expenditures that are directly attributable to the acquisition of the asset. Depreciation is recorded to recognize the cost of assets over their useful lives. The estimated useful lives and depreciation methods are reviewed at the end of each reporting period, with the effect of any changes in estimate accounted for on a prospective basis. ​ Asset type Methods Rates Computer equipment Declining balance method 55% Machinery and equipment Declining balance method 20% Rolling stock Declining balance method 30% Leasehold improvements Straight-line method Over the term of the lease Boat rental fleet Straight-line method 15 years Moulds Straight-line method 25 years ​ Any item of property and equipment is derecognized 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 the disposal or retirement of an asset is determined as the difference between the sales and proceeds and the carrying amount of the asset and is recognized in profit or loss. Repairs and maintenance costs that do not improve or extend productive life are recognized in profit or loss in the period in which the costs are incurred.
Intangible assets and goodwill	Intangible assets and goodwill Expenditure on research activities is recognized in net earnings as incurred. Development expenditure is capitalized only if the expenditure can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable and the Company intends to and has sufficient resources to complete development and to use or sell the asset. Otherwise, it is recognized in net earnings as incurred. The Company has not capitalized any development costs. When awarded with government grants and income tax credits, the Company recognizes the income either in net income (loss), netted with the related expenses, or as a reduction of the cost, when related with capitalized development expenditure. Goodwill arising from business combinations is initially recognized when the fair value of the separately identifiable assets the Company acquired and liabilities the Company assumed is lower than the consideration paid [including the recognized amount of the non-controlling interest, if any]. If the fair value of the consideration transferred is lower than that of the separately identified assets and liabilities, the Company immediately recognizes the difference as a gain in the consolidated statement of comprehensive loss. Other intangible assets, including intellectual property, software, trade name, backlog and website that have finite useful lives are measured at cost less accumulated amortization and accumulated impairment losses. Amortization is calculated over the cost of the asset less its residual value. Amortization is recognized in net earnings on a straight-line basis over the estimated useful lives of intangible assets from the date that they are available for use. The estimated useful lives are as follows: ​ Asset type Methods Rates Intellectual property Straight-line method 10 years Software Straight-line method 7 years Trade name Straight-line method 5 years Backlog Straight-line method 3 years Website Straight-line method 5 years ​ Amortization methods, useful lives and residual values are reviewed at each reporting date and adjusted if appropriate.
Impairment of non-financial assets	Impairment of non-financial assets Non-financial assets other than goodwill At the end of each reporting period, the Company reviews the carrying amounts of its non-financial assets, other than goodwill, to determine whether there is any indication of impairment. If any such indication exists, the recoverable amount of the asset is estimated. Where it is not possible to estimate the recoverable amount of an individual asset, assets are grouped together into the smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or groups of assets [the “cash-generating unit”, or “CGU”]. Recoverable amount is the greater 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 discount rate that reflects current market assessments of the time value of money and the risks specific to the asset or CGU. If the recoverable amount of an asset or CGU is lower than its carrying amount, the carrying amount is reduced to its recoverable amount. An impairment loss is recognized immediately in the consolidated statement of comprehensive loss. Where an impairment loss subsequently reverses, the carrying amount of the asset or CGU is increased to the revised recoverable amount, to the extent that the carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized. A reversal of an impairment loss is recognized immediately in the consolidated statement of comprehensive loss. Goodwill After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For purposes of impairment testing, goodwill is allocated to each of the Company’s CGU [or groups of CGUs] that is expected to benefit from the synergies of the combination. A CGU to which goodwill has been allocated is tested for impairment annually, or more frequently when there is indication that the CGU may be impaired. If the recoverable amount of the CGU is less than its carrying amount, the impairment loss is allocated first to reduce the goodwill allocated to the CGU and then, to reduce the carrying amounts of the other assets in the CGU on a pro-rata basis. Any impairment loss is recognized in the consolidated statement of comprehensive loss. An impairment loss recognized for goodwill is not reversed in subsequent periods.
Trade and other payables	Trade and other payables These amounts represent liabilities for goods and services provided to the entity prior to the end of the financial year and which are unpaid. Due to their short-term nature, they are measured at amortized cost and are not discounted. The amounts are unsecured and are usually paid within 30 days of recognition.
Provisions	Provisions Provisions are recognized when the Company has a present obligation as a result of a past event, it is probable the Company will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the reporting date, taking into account the risks and uncertainties surrounding the obligation. If the time value money is material, provisions are discounted using a current pre-tax rate specific to the liability. The increase in the provision resulting from the passage of time is recognized as a finance cost.
Fair value measurement	Fair value measurement When an asset or liability, financial or non-financial, is measured at fair value for recognition or disclosure purposes, the fair value is based on 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; and assumes that the transaction will take place either: in the principal market; or in the absence of a principal market, in the most advantageous market. Fair value is measured using the assumptions that market participants would use when pricing the asset or liability, assuming they act in their economic best interests. For non-financial assets, the fair value measurement is based on its highest and best use. Valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, are used, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs. Assets and liabilities measured at fair value are classified into three levels, using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. Classifications are reviewed at each reporting date and transfers between levels are determined based on a reassessment of the lowest level of input that is significant to the fair value measurement.
Financial instruments	Financial instruments Classification and measurement of financial instruments The Company measures its financial assets and financial liabilities at fair value on initial recognition, which is typically the transaction price unless a financial instrument contains a significant financing component. Subsequent measurement is dependent on the financial instrument’s classification which in the case of financial assets, is determined by the context of the Company’s business model and the contractual cash flow characteristics of the financial asset. Financial assets are classified into two categories: [1] measured at amortized cost and [2] fair value through profit and loss [“FVTPL”]. Financial liabilities are subsequently measured at amortized cost at the effective interest rate, other than financial liabilities that are measured at FVTPL or designated as FVTPL where any change in fair value resulting from an entity’s own credit risk is recorded as other comprehensive income [“OCI”]. Amortized cost The Company classifies trade and other receivables, other financial assets, trade and other payables, other financial liabilities, long-term debt and advances to/from related parties as financial instruments measured at amortized cost. The contractual cash flows received from the financial assets are solely payments of principal and interest and are held within a business model whose objective is to collect the contractual cash flows. Fair value through profit and loss The Company classifies debentures as financial instruments measured at fair value through profit and loss since the contractual cash flows received from the financial asset are not solely payments of principal and interest. Impairment of financial assets The Company recognizes a loss allowance for expected credit losses on financial assets measured at amortized cost. The measurement of the loss allowance depends upon the Company’s assessment at the end of each reporting period as to whether the financial instrument’s credit risk has increased significantly since initial recognition, based on reasonable and supportable information that is available, without undue cost or effort to obtain. Where there has not been a significant increase in exposure to credit risk, a 12-month expected credit loss allowance is estimated. The amount of expected credit loss recognized is measured on the basis of the probability weighted present value of anticipated cash shortfalls over the life of the instrument discounted at the original effective interest rate. Impairment provisions for current and non-current trade receivables are recognized based on the simplified approach within IFRS 9 using a provision matrix in the determination of the lifetime expected credit losses. Equity instruments Financial instruments issued by the Company are classified as equity only to the extent that they do not meet the definition of a financial liability or financial asset. An equity instrument is any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities. Equity instruments issued by the Company are recorded at the proceeds received, net of direct issuance costs. The Company’s shares are classified as equity instruments.
Revenue recognition	Revenue recognition Revenue is recognized at an amount that reflects the consideration to which the Company is expected to be entitled in exchange for transferring goods or services to a customer. For each contract with a customer, the Company: ● identifies the contract with the customer; ● identifies the performance obligations in the contract; ● determines the transaction price which takes into account estimates of variable consideration and the time value of money; ● allocates the transaction price to separate performance obligations on the basis of relative stand-alone selling price of each distinct good or service to be delivered; and, ● recognizes revenue when or as each performance obligation is satisfied in a manner that depicts the transfer to the customer of the goods or services promised. The Company enters into contracts with customers, as well as distributor agreements with specific distributors for the sale of boats. Sale of boats Revenue from the sale of boats, including incidental shipping fees, is recognized at the point in time when the customer obtains control of the goods, which is generally at the shipping point. In the context of its distributor agreements, control is passed at the shipping point to the distributor as the Company has no further performance obligations at that point. The Company concluded that it is the principal in its revenue arrangements, because it typically controls the boats before transferring them to the customer. The amount of consideration the Company receives, and the revenue recognized varies with volume rebate programs offered to distributors. When the Company offers retrospective volume rebates, it estimates the expected volume rebates based on an analysis of historical experience, to the extent that it is highly probable that a significant reversal will not occur. The Company adjusts its estimate of revenue related to volume rebates at the earlier of when the most likely amount of consideration expected to be received changes or when the consideration becomes fixed. The Company recognizes customer deposits on the sale of boats as contract liabilities. Boat rental and boat club membership revenue Revenue from boat rentals is recognized at a point in time when the services are completed. Boat club membership revenue is recognized over time as the service is provided. These services are typically provided, and thus revenue is typically recognized, on a monthly basis. The Company recognizes customer prepayments on boat rentals and boat club memberships as contract liabilities. Sale of parts and boat maintenance Revenue from the sale of parts and related maintenance services are recognized at the point in time when the customer obtains control of the parts and when services are completed. Other Other revenue is recognized when it is received or when the right to receive payment is established. Contract liabilities A contract liability is recognized if a payment is received, or a payment is due [whichever is earlier] from a customer before the Company transfers the related goods or services. Contract liabilities are recognized as revenue when the Company performs under the contract [i.e., transfers control of the related goods or services to the customer].
Share-based payments	Share-based payments The Company has a share option plan for key employees, consultants, advisors, officers and directors from which options to purchase common stock of the Company are issued. The Company also issues warrants to non-employees granting the right to purchase common stock of the Company at a determined exercise price . All share-based remuneration is ultimately recognized as an expense in profit or loss with a corresponding credit to contributed surplus. If vesting periods or other vesting conditions apply, the expense is allocated over the vesting period, based on the best available estimate of the number of share options expected to vest. Any adjustment to cumulative share-based compensation resulting from a revision is recognized in the current period. The number of vested options ultimately exercised by holders does not impact the expense recorded in any period.
Foreign currency translation	Foreign currency translation The Company’s consolidated financial statements are presented in Canadian dollars, which is also the parent company’s functional currency. The functional currencies of 7858078 Canada Inc. and EB Rental Ltd. are the Canadian dollar and the US dollar, respectively. The Company and its subsidiaries each determine their functional currency based on the currency of the primary economic environment in which they operate. Transactions denominated in a currency other than the functional currency of an entity are translated at the exchange rate in effect on the transaction date. The resulting exchange gains and losses are included in each entity’s net income (loss) in the period in which they arise. The Company’s foreign operations are translated to the Company’s presentation currency, for inclusion in the consolidated financial statements. Foreign-denominated monetary and non-monetary assets and liabilities of foreign operations are translated at exchange rates in effect at the end of the reporting period and revenue and expenses are translated at exchange rates in effect at the transaction date. The resulting translation gains and losses are included in other comprehensive loss with the cumulative gain or loss reported in accumulated other comprehensive income. On disposal of a foreign operation, the component of OCI relating to that particular foreign operation is reclassified to profit or loss. The exchange rates for the currencies used in the preparation of the consolidated financial statements were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Exchange rate as at ​ Average exchange rate for year ended ​ August 31, August 31, August 31, August 31, ​ ​ 2022 ​ 2021 ​ 2022 ​ 2021 US dollar 1.3076 1.2630 1.2717 1.2688
Taxes	Taxes Tax expense comprises current and deferred tax. Tax is recognized in net income (loss) except to the extent it relates to items recognized in other comprehensive income or directly in equity. Current tax Current tax expense is based on the results for the period as adjusted for items that are not taxable or not deductible. Current tax is calculated using tax rates and laws that were enacted or substantively enacted at the end of the reporting period. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. Deferred tax Deferred taxes are the taxes expected to be payable or recoverable on differences between the carrying amounts of assets in the statement of financial position and their corresponding tax bases used in the computation of taxable profit. Deferred tax liabilities are generally recognized for all taxable temporary differences between the carrying amounts of assets and their corresponding tax bases. Deferred tax assets are recognized to the extent that it is probable that taxable profits will be available against which deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized. Such assets and liabilities are not recognized if the temporary difference arises from the initial recognition of goodwill or from the initial recognition [other than in a business combination] of other assets in a transaction that affects neither the taxable profit nor the accounting profit. The Company offsets deferred tax assets and deferred tax liabilities if and only if it has a legally enforceable right to set off current tax assets and current tax liabilities and the deferred tax assets and deferred tax liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred tax liabilities or assets are expected to be settled or recovered.
Earnings per share	Earnings per share Basic earnings per share is calculated by dividing the profit or loss attributable to equity holders of the Company by the weighted average number of common stock outstanding during the year. Diluted income per share is calculated by dividing the profit attributable to equity holders of the Company by the weighted average number of common stock outstanding, adjusted for the effects of all dilutive potential common stock. The weighted average number of common stock outstanding is increased by the number of additional common stock that would have been issued by the Company assuming exercise of all options with exercise prices below the average market price for the year.
Standards issued but yet not effective	Standards issued but yet not effective The new and amended standards and interpretations that are issued, but not yet effective, up to the date of issuance of the Company’s financial statements are disclosed below. The Company intends to adopt these new and amended standards and interpretations, if applicable, when they become effective. Onerous Contracts – Costs of Fulfilling a Contract – Amendments to IAS 37 In May 2020, the IASB issued amendments to IAS 37 to specify which costs an entity needs to include when assessing whether a contract is onerous or loss-making. The amendments apply a “directly related cost approach”. The costs that relate directly to a contract to provide goods or services include both incremental costs and an allocation of costs directly related to contract activities. General and administrative costs do not relate directly to a contract and are excluded unless they are explicitly chargeable to the counterparty under the contract. The amendments are effective for annual reporting periods beginning on or after January 1, 2022. The amendments are not expected to have a material impact on the Company’s consolidated financial statements. Property, Plant and Equipment: Proceeds before Intended Use – Amendments to IAS 16 Property, plant and equipment The amendment prohibits entities from deducting from the cost of an item of property, plant and equipment, any proceeds of the sale of items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognizes the proceeds from selling such items, and the costs of producing those items, in profit or loss. The amendment is effective for annual reporting periods beginning on or after January 1, 2022 and must be applied retrospectively to items of property, plant and equipment made available for use on or after the beginning of the earliest period presented when the entity first applies the amendment. The amendments are not expected to have a material impact on the Company’s consolidated financial statements.

Incorporation and nature of business
Incorporation and nature of business	1. Incorporation and nature of business Vision Marine Technologies Inc. [the “Company”] was incorporated on August 29, 2012 and its principal business is to manufacture and sell or rent electric boats. The Voting Common Shares of the Company are listed under the trading symbol “VMAR” on Nasdaq. The Company is incorporated in Canada and its head office and registered office is located at 730 Curé-Boivin boulevard, Boisbriand, Quebec, J7G 2A7. Business seasonality The Company’s operating results generally vary from quarter to quarter as a result of changes in general economic conditions and seasonal fluctuations, among other things, in each of its reportable segments. This means the Company’s results in one quarter are not necessarily indicative of how the Company will perform in a future quarter. Sale of electric boats The sale of electric boats segment has a seasonal aspect to its operations. Most customers purchase their electric boats from the Company with the intention of utilizing them during the summer period which typically runs from early June to late August and corresponds to the Company’s fourth quarter of a financial year. As such, the revenues in this operating segment fluctuates based on the level of boat deliveries, with a high and a low in the fourth quarter and the first quarter, respectively. Rental of electric boats Revenue generated by the rental of electric boats segment also has a seasonal aspect to its operations. Boat rental as an activity is highly sought by customers when the weather is milder, which is typically the case during the period from May to August. A colder-than-expected or rainier summer in any given year could have an impact on the segment’s revenues and hence on its profitability. Revenue from the boat club memberships is not impacted by seasonality as the memberships are typically on an annual basis.	1. Incorporation and nature of business Vision Marine Technologies Inc. [the “Company”] was incorporated on August 29, 2012 and its principal business is to manufacture and sell or rent electric boats. The Voting Common Shares of the Company are listed under the trading symbol “VMAR” on Nasdaq. The Company is incorporated in Canada and its head office and registered office is located at 730 Curé-Boivin boulevard, Boisbriand, Quebec, J7G 2A7. Business seasonality The Company’s operating results generally vary from quarter to quarter as a result of changes in general economic conditions and seasonal fluctuations, among other things, in each of its reportable segments. This means the Company’s results in one quarter are not necessarily indicative of how the Company will perform in a future quarter. Sale of electric boats The sale of electric boats segment has a seasonal aspect to its operations. Most customers purchase their electric boats from the Company with the intention of utilizing them during the summer period which typically runs from early June to late August and corresponds to the Company’s fourth quarter of a financial year. As such, the revenues in this operating segment fluctuate based on the level of boat deliveries, with a high and a low in the fourth quarter and the first quarter, respectively.

The Debentures bear interest at a rate of 10% per annum, payable annually in arrears, and have a 36-month term [the “Term”]. The Debentures are convertible at any time at the option of the Company into common shares of Limestone [“Common Shares”] at a conversion price of $0.36 per Common Share [the “Conversion Price”]. If at any time following 120 days from the date of issuance of the Debentures [the “Closing Date“] and prior to the date that is 30 days prior to the end of the Term, the volume weighted average closing price of the Common Shares on the TSX Venture Exchange, or such other exchange on which the Common Shares may be listed, is equal to or higher than $0.50 per Common Share for 20 consecutive trading days, Limestone may notify the Company that the Debentures will be automatically converted into Common Shares at the Conversion Price 30 days following the date of such notice. The Debentures are carried at fair value through profit and loss and are considered as Level 2 financial instruments in the fair value hierarchy. On January 20, 2023, Limestone announced that Limestone’s U.S. subsidiaries filed a Chapter 7 of the Bankruptcy Code in the U.S. As a result, the Company recorded an impairment on the entire value of the Debentures at the amount of nil and $2,637,000 in the three and nine months ended May 31, 2023 [May 31, 2022 – nil]. For the three and nine months ended May 31, 2023, the Company recorded a loss of nil and $109,667 respectively [May 31, 2022 – $115,000 and $436,500 respectively] in net finance expense for change in the fair value of the Debentures [ note 19	8. Debentures On May 14, 2021, the Company subscribed for and purchased 3,400 senior unsecured subordinated convertible debentures of The Limestone Boat Company Limited [“Limestone”], a publicly traded company listed under the trading symbol "BOAT" on the TSX Venture Exchange [the "Debentures"], for an aggregate amount of $3,400,000. The Debentures bear interest at a rate of 10% per annum, payable annually in arrears, and have a 36-month term [the “Term”].

If at any time following 120 days from the date of issuance of the Debentures [the “Closing Date“] and prior to the date that is 30 days prior to the end of the Term, the volume weighted average closing price of the Common Shares on the TSX Venture Exchange, or such other exchange on which the Common Shares may be listed, is equal to or higher than $0.50 per Common Share for 20 The Debentures are carried at fair value through profit and loss and are considered as Level 2 financial instruments in the fair value hierarchy. For the year ended August 31, 2022, the Company recorded a loss of $670,000 [2021 - $550,000; 2020 - Nil] for the change in fair value of the Debentures and interest income of $340,000 [2021 - $85,000; 2020 - Nil] in net income (loss) as a net financial expense. Subsequent to year end, Limestone announced that it has implemented significant cost savings measures, as well as the withdrawal of its previously proposed debt financings. As Limestone continues to pursue alternative liquidity and financing proposals, these factors may have a negative impact on the key assumptions described in Note 25 used by the Company to determine the fair value of the Debentures subsequent to the reporting date. Although the estimates of the fair value of the Debentures as at August 31, 2022 are based on management’s best knowledge and estimates of the amount, events or actions at that time, the valuation in future periods ultimately may differ from those estimates.

The Company assessed the classification of the compound financial instrument issued, whether the warrants issued meet the criteria of an equity instrument (i.e. the warrants would be settled by the issuance of fixed number of common shares of the Company at a fixed exercise price) or a financial liability. Since the exercise price of these warrants is denominated in U.S. dollar, while the functional currency of the Company is Canadian dollar, the value of the proceeds on exercise of the warrants is not fixed and will vary based on the foreign exchange rate movements. As such, the Company classified the warrants, other than warrants issued as compensation for goods and services, as derivative liabilities, measured at fair value at initial recognition and at each reporting period. Refer to note 16 for details on the assumptions used to determine the fair value. Any changes in fair value are recorded as gain or loss in the consolidated statement of comprehensive loss. At issuance and as at May 31, 2023, the derivative liabilities amounted to $4,866,082 and $3,253,024, respectively [August 31, 2022 – Nil], with the allocated transaction costs of $489,096 recorded in net finance expense [note 19]	18.

Fair value measurement and hierarchy
Fair value measurement and hierarchy	20. Fair value measurement and hierarchy The fair value measurement of the Company’s financial and non-financial assets and liabilities utilizes market observable inputs and data as far as possible. Inputs used in determining fair value measurements are categorized into different levels based on how observable the inputs used in the valuation technique utilized are (the “fair value hierarchy”): ● Level 1: Quoted prices in active markets for identical items [unadjusted]; ● Level 2: Observable direct or indirect inputs other than Level 1 inputs; and ● Level 3: Unobservable inputs [i.e., not derived from market data]. ​ The classification of an item into the above levels is based on the lowest level of the inputs used that has a significant effect on the fair value measurement of the item. Transfers of items between levels are recognized in the period they occur. The carrying amount of trade and other receivables, advances to/from related parties and trade and other payables are assumed to approximate their fair value due to their short-term nature. The fair value of financial liabilities is estimated by discounting the remaining contractual maturities at the current market interest rate that is available for similar financial liabilities. Classified as Level 2, the fair value of Debentures was estimated using the partial differential equation model to value convertible debentures that include a call feature. Key assumptions used in the model include volatility, which is based on actual trading data, difference in volatility since initial issuance of the instrument and similar instruments on the market, and credit spread, which is based on corporate bond yield spreads in the market and credit spread data for similar public companies. The model included a fair value adjustment based on an initial calibration exercise. During the three months ended February 28, 2023, the Company recorded an impairment loss on the Debentures based on the estimated recoverable amount of the financial asset [note 5] The fair value of the derivative liabilities related to the warrants issued is classified as Level 2 in the fair value hierarchy and is calculated using the Black-Scholes Option Pricing Model using the historical volatility of comparable companies as an estimate of future volatility. As at May 31, 2023, if the volatility used was increased by 10% the impact would be an increase of $378,000 to the derivative liabilities with corresponding increase in total comprehensive loss.
