Background of the Company [abstract]
BACKGROUND OF THE COMPANY	1. BACKGROUND OF THE COMPANY Telesat Corporation (the “Corporation” or “Company”) was incorporated under the Business Corporations Act The Corporation is a global satellite operator, providing mission -critical -of-the-art -1 The Corporation has commenced the development of a constellation of low earth orbit (“LEO”) satellites and integrated terrestrial infrastructure, called “Telesat Lightspeed”. In January 2018, the first LEO satellite, LEO The Corporation began trading on the Nasdaq Global Select Market and the Toronto Stock Exchange on November 19, 2021 under the ticker symbol “TSAT”. This followed the closing of Telesat Canada’s transaction with Loral Space & Communications Inc. (“Loral”) and Public Sector Pension Investment Board (“PSP Investments”) (the “Transaction”), in which Loral’s stockholders and Telesat Canada’s other equity holders exchanged their interests for equity in the new public holding company. The Transaction resulted in the Loral stockholders, PSP Investments and certain individual shareholders (other than the Voting Directors) of Telesat Canada owning indirectly through the Corporation and Telesat Partnership LP (the “Partnership”) approximately the same percentage of equity as they held in Telesat Canada; the Corporation becoming the publicly traded general partner of the Partnership; and the Partnership indirectly owning all of the economic interests in Telesat Canada and Loral becoming a wholly owned subsidiary of the Partnership. For further details on the Transaction, refer to the Corporation’s Registration Statement on Form F -4 http://www.sec.gov -Offering http://www.sedar.com References herein to “Telesat” or “Company” refer to Telesat Canada and its subsidiaries prior to November 19, 2021 and Telesat Corporation and its subsidiaries subsequently. Unless the context states or requires otherwise, references herein to the “financial statements” or similar terms refer to the audited consolidated financial statements of Telesat. On March 28, 2023, these financial statements were approved by the Audit Committee of the Board of Directors and authorized for issue.

BASIS OF PRESENTATION	2. BASIS OF PRESENTATION Statement of Compliance The consolidated financial statements were prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The accounting policies in Note 4 were consistently applied to all years presented. Basis of Consolidation Subsidiaries These consolidated financial statements include the results of the Telesat and subsidiaries controlled by the Company. Control is achieved when the Company has power over an entity, has exposure, or rights to variable returns from its involvement with an entity, and has the ability to use the power over an entity to affect the amount of its return. The most significant subsidiaries are listed in Note 35. The portion of equity ownership in a subsidiary that is not directly or indirectly attributable to the Company is recorded under non -controlling -controlling -controlling -controlling -by-acquisition -controlling -controlling -controlling Profit or loss and each component of other comprehensive income (loss) are attributed to the owners of the Company and to the non -controlling -controlling -controlling Joint arrangements A joint operation is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to their share of the assets and revenue, and obligations for the liabilities and expenses, relating to the arrangement. The Company’s consolidated financial statements include the Company’s share of the assets, liabilities, revenue and expenses of its interest in joint operations. The consolidated financial statements have been prepared on a historical cost basis except for certain financial instruments which were measured at their fair values, as explained in the accounting policies below. Historical cost is based on the fair value of the consideration given or received in exchange for assets or liabilities.

CHANGES IN ACCOUNTING POLICIES	3. CHANGES IN ACCOUNTING POLICIES IFRS Interpretation Committee (“IFRIC”), Software as a Service arrangements In April 2021, the IFRIC published an agenda decision clarifying how arrangements in respect of a specific part of cloud technology, Software as a Service (“SaaS”) should be accounted for. The IFRIC interpretation provided specific guidance and included explanatory material which provided additional insights with respect to circumstances in relation to configuration and customization costs incurred in implementing SaaS. Among other things, the interpretation clarified the nature of expenditures that met the definition of an intangible asset, the methods of differentiating between intangible assets and expenses and the pattern in which an entity benefits from expenditure that does not qualify as an intangible asset. The Company adopted the IFRIC agenda decision retroactively. The impact on the balance sheet as at December 31, 2021 was as follows: Satellites, property and other equipment $ (2,087 ) Intangible assets $ (1,419 ) Accumulated earnings $ 3,495 Reserves $ 11 The impact on the statements of income (loss) and the statements of comprehensive income (loss) was as follows: For the years ended December 31, 2021 2020 Operating expenses $ 2,895 $ 758 Amortization $ (158 ) $ — Foreign currency translation adjustments $ 11 $ — Net income (loss) per common share attributable to Telesat Corporation shareholders – basic $ (0.05 ) $ (0.01 ) Net income (loss) per common share attributable to Telesat Corporation shareholders – diluted $ (0.05 ) $ (0.01 )

SIGNIFICANT ACCOUNTING POLICIES	4. SIGNIFICANT ACCOUNTING POLICIES Segment Reporting The Company operates in a single operating segment, in which it provides satellite -based Foreign Currency Translation Unless otherwise specified, all figures reported in the consolidated financial statements and associated note disclosures are presented in Canadian dollars, which is the functional and presentation currency of the Company. Each of the subsidiaries of the Company determines its own functional currency and uses that currency to measure items on their separate financial statements. For the Company’s non -foreign -monetary Upon consolidation of the Company’s foreign operations that have a functional currency other than the Canadian dollar, assets and liabilities are translated at the year end exchange rate, and revenue and expenses are translated at the average exchange rates of the month in which the transactions occurred. Gains or losses on the translation of foreign subsidiaries are recognized in other comprehensive income (loss). Cash and Cash Equivalents All highly liquid investments with an original maturity of three months or less, or which are available upon demand with no penalty for early redemption, are classified as cash and cash equivalents. Cash and cash equivalents are comprised of cash on hand, demand deposits, short -term Revenue Recognition Telesat recognizes revenue from satellite services on a monthly basis as services are performed in an amount that reflects the consideration the Company expects to receive in exchange for those services. Telesat accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability is considered probable. Revenue from a contract to sell consulting services is recognized as follows: • • Equipment sale revenue is recognized when the customer obtains control of the equipment, being at the time the equipment is delivered to and accepted by the customer. Only equipment sales are subject to warranty or return and there is no general right of return. Historically, the Company has not incurred significant expenses for warranties. When a transaction involves more than one product or service, revenue is allocated to each performance obligation based on its relative stand -alone Deferred Revenue Deferred revenue represents the Company’s liability for the provision of future services and is classified on the balance sheet in other current and long -term -line -term A significant financing component will only occur in the following circumstances: • • • In the case of the existence of a significant financing component, the amount of the consideration is adjusted to reflect what the cash selling price of the promised service would have been if payments had occurred as control of the service was transferred to the customer. The discount rate used in determining the significant financing component is the rate that would be reflected in a separate financing transaction between the Company and the customer at contract inception. Inventories Inventories are valued at the lower of cost and net realizable value and consist of finished goods and work in process. Cost for substantially all network equipment inventories are determined on a weighted average cost basis. Cost for work in process and certain one -of-a-kind Borrowing Costs Borrowing costs are incurred on the Company’s debt financing. Borrowing costs attributable to the acquisition, production or construction of a qualifying asset are added to the cost of that asset. The Company has defined a qualifying asset as an asset that takes longer than twelve months to be ready for its intended use or sale. Capitalization of borrowing costs continues until such time that the asset is substantially ready for its intended use or sale. Borrowing costs are determined based on specific financing related to the asset, or in the absence of specific financing, the borrowing costs are calculated on the basis of a capitalization rate which is equal to the Company’s weighted average cost of debt. All other borrowing costs are expensed when incurred. Leases At the inception of a contract, the Company assesses whether a contract is, or contains, a lease based on whether or not the contract conveys the right to control the use of the asset for a period of time in exchange for consideration. The Company recognizes a right -of-use -of-use -of-use The lease term is the non -cancellable After the commencement date, the right -of-use -line The lease liability is remeasured when there is a change in future lease payments, arising from a change in index or rate, or if there is a change in the assessment of whether the Company will exercise a purchase, extension or termination option. The amount of the remeasurement of the lease liability is also recognized as an adjustment to the right -of-use -of-use The Company has elected to not recognize a right -of-use -line The Company has also elected the practical expedient, for property leases, not to separate the non -lease -lease Government Grants Government grants are recognized where there is a reasonable assurance that the grant will be received and the attached conditions will be complied with. When the grant relates to an expense, the grant is recorded as a deduction to the related expense incurred over the same period. When the grant relates to an asset, the grant is deducted from the carrying amount of the related asset as the grant is receivable. Software as a service arrangements A SaaS cloud computing arrangement is evaluated as to whether it met the criteria under IAS Intangible Assets Leases Telesat may enter into a SaaS cloud computing arrangement with a supplier where the contract conveys to Telesat a right to receive future access over the contract term to the supplier’s application software running on the supplier’s cloud infrastructure. The right to receive access does not provide Telesat with a software asset and, therefore, the access to the software is a service which is received over the contract term. The assessment of whether configuration or customization of a software results in an intangible asset for Telesat depends on the nature and output of the configuration and customization performed. In some circumstances, the arrangement may result in additional code from which Telesat has the power to obtain the future economic benefits and to restrict others’ access to those benefits. In that case, in determining whether to recognise the additional code as an intangible asset, Telesat assesses whether the additional code is identifiable and meets the recognition criteria under IAS 38. Separately acquired intangible rights (i.e. software licenses in cloud computing arrangements) are normally recognized as assets. Satellites, Property and Other Equipment Satellites, property and other equipment, which are carried at cost, less accumulated depreciation and any accumulated impairment losses, include the contractual cost of equipment, capitalized engineering costs, capitalized borrowing costs during the construction or production of qualifying assets, and with respect to satellites, the cost of launch services, and launch insurance. Depreciation is calculated using the straight -line Below are the estimated useful lives in years of satellites, property and other equipment as at December 31, 2022. Years Satellites 12 to 15 Right-of-use assets 2 to 27 Antennas, satellite control & communication equipment 8 to 20 Building, equipment & other 3 to 25 Construction in progress is not depreciated as depreciation only commences when the asset is ready for its intended use. For satellites, depreciation commences on the day the satellite becomes available for service. The investment in each satellite will be derecognized from the accounts when the satellite is retired. When other property is retired from operations at the end of its useful life, the cost of the asset and accumulated depreciation are derecognized from the accounts. Earnings are credited with the amount of any net salvage value and charged with any net cost of removal. When an asset is sold prior to the end of its useful life, the gain or loss is recognized immediately in other operating gains (losses), net. In the event of an unsuccessful launch or total in -orbit -orbit Liabilities related to decommissioning and restoration of retiring property and other equipment are measured at fair value with a corresponding increase to the carrying amount of the related asset. The liability is accreted over the period of expected cash flows with a corresponding charge to interest expense. The liabilities recorded to date have not been significant and are reassessed at the end of each reporting period. There are no decommissioning or restoration obligations for satellites. Satellite Performance Incentive Payments Satellite performance incentive payments are obligations payable to satellite manufacturers over the lives of certain satellites. The present value of the payments are capitalized as part of the cost of the satellite and recognized as part of the depreciation of the satellite. Impairment of Long-Lived Assets Tangible fixed assets and finite life intangible assets are assessed for impairment on an annual basis or more frequently when events or changes in circumstances indicate that the carrying value of an asset exceeds the recoverable amount. Tangible fixed assets and finite life intangible assets are also assessed for indicators of impairment or impairment reversals at each reporting period. In cases where there are indicators of impairment, the recoverable amount of the asset, which is the higher of its fair value less costs of disposal and its value in use, is determined. If it is not possible to measure the recoverable amount for a particular asset, the Company determines the recoverable amount of the cash generating unit (“CGU”) with which it is associated. A CGU is the smallest identifiable group of assets that generates cash inflows which are largely independent of the cash inflows from other assets or groups of assets. The Company measures value in use on the basis of the estimated future cash flows to be generated by an asset or CGU. These future cash flows are based on the Company’s latest business plan information and are discounted using rates that best reflect the time value of money and the specific risks associated with the underlying asset or assets in the CGU. The fair value less costs of disposal is the price that would be received to sell an asset or CGU in an orderly transaction between market participants at the measurement date. For the impairment assessment, the fair value is calculated on a recurring basis and is calculated using level 3 of the fair value hierarchy. An impairment loss is the amount by which the carrying amount of an asset or CGU exceeds its recoverable amount. When an impairment loss subsequently reverses, the carrying amount of the asset (or a CGU) is increased to the revised measure of its recoverable amount, so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or CGU) in prior years. Impairment losses and reversals of impairment losses are recognized in other operating gains (losses), net. Goodwill and Intangible Assets The Company accounts for business combinations using the acquisition method of accounting, which establishes specific criteria for the recognition of intangible assets separately from goodwill. Goodwill represents the excess between the total of the consideration transferred over the fair value of net assets acquired. After initial recognition at cost, goodwill is measured at cost less any accumulated impairment losses. The Company distinguishes intangible assets between assets with finite and indefinite useful lives. Intangible assets with indefinite useful lives are comprised of the Company’s trade name, intellectual property, and orbital slots. These assets are carried at cost less any accumulated impairment losses. Finite life intangible assets, which are carried at cost less accumulated amortization and any accumulated impairment losses, consist of revenue backlog, customer relationships, customer contracts, concession rights, transponder rights, software and patents. Intangible assets with finite lives are amortized over their estimated useful lives using the straight -line Below are the estimated useful lives in years of the finite life intangible assets as at December 31, 2022. Years Revenue backlog 17 Customer relationships 20 to 21 Customer contracts 15 Concession rights 5 to 15 Transponder rights 16 Software 5 Patents 18 Impairment of Goodwill and Indefinite Life Intangible Assets An assessment for impairment of goodwill and indefinite life intangible assets is performed annually, or more frequently whenever events or changes in circumstances indicate that the carrying amounts of these assets are likely to exceed their recoverable amount. Goodwill is tested for impairment at the entity level as this represents the lowest level within the Company at which the goodwill is monitored for internal management purposes, and is not larger than an operating segment. With the exception of trade name, which has not been allocated to any CGU and is tested for impairment at the asset level, indefinite life intangible assets are tested for impairment at the CGU level. In the case of orbital slots, the CGU is based on geography. A quantitative impairment test consists of assessing the recoverable amount of an asset, which is the higher of its fair value less costs of disposal and its value in use. For the quantitative impairment assessment, fair value is calculated on a recurring basis and is calculated using level 2 or level 3 of the fair value hierarchy depending on the valuation approach being utilized. Orbital Slots In performing the orbital slot impairment analysis, the Company determines, for each CGU, the recoverable amount. The recoverable amount is defined as the higher of the fair value less costs of disposal, and its value in use on an annual basis. To the extent that the recoverable amount is less than the carrying value of the asset, an impairment exists and the asset is written down to its recoverable amount. Fair value less costs of disposal is the price that would be received to sell the CGU in an orderly transaction between market participants at the measurement date. In order to determine the fair value less costs of disposal, the Company uses either a market or income approach. Under a market approach, the Company measures what an independent third party would pay to purchase the orbital slots by looking to actual market transactions for similar assets. Under an income approach, the fair value is determined to be the sum of the projected discounted cash flows over a discrete period of time. The value in use amount is the present value of the future cash flows expected to be derived from the CGU. The determination of this amount includes projections of cash inflows from the continuing use of the asset and cash outflows that are required to generate the associated cash inflows. These cash flows are discounted at an appropriate discount rate. Goodwill In performing the goodwill impairment analysis, the Company assesses the recoverable amount of goodwill. The recoverable amount is the higher of the income approach as well as the market approach in the determination of the fair value of goodwill at the entity level. Under the income approach, the sum of the projected discounted cash flows for the next five years, or a longer period if justified by the most recent financial plan approved by management, in addition to a terminal value are used to determine the fair value at the entity level. Under the market approach, the fair value at the entity level is determined based on market multiples derived from comparable public companies. Under both approaches, all assumptions used are based on management’s best estimates. The discount rates are consistent with external sources of information. Trade Name For the purposes of impairment testing, the fair value of the trade name is determined using an income approach, specifically the relief from royalties method. The relief from royalties method is comprised of two major steps: i) ii) In determining the hypothetical royalty rate in the relief from royalties method, the Company considered comparable license agreements, operating earnings benchmarks, an excess earnings analysis to determine aggregate intangible asset earnings, and other qualitative factors. Intellectual Property In performing the intellectual property impairment analysis, the Company determines its recoverable amount. The recoverable amount is the fair value less costs of disposal. To the extent that the recoverable amount is less than the carrying value of the asset, an impairment exists and the asset is written down to its recoverable amount. The Company measures value in use on the basis of the estimated future cash flows to be generated by an asset. These future cash flows are based on the Company’s latest business plan information approved by senior management and are discounted using rates that best reflect the time value of money and the specific risks associated with the underlying asset. Financial Instruments Financial assets are initially recognized at fair value. Financial assets are measured using one of three measurement approaches (fair value through profit or loss (“FVTPL”), fair value through other comprehensive income (“FVTOCI”), or amortized cost). A financial asset is measured at amortized cost if it is not designated as FVTPL, it is held within a business model whose objective is to hold assets to collect contractual cash flows and its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. A debt investment is measured at FVTOCI if it is not designated at FVTPL, it is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets and its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amounts outstanding. On initial recognition of an equity investment that is not held for trading, the Company may irrevocably elect to present subsequent changes in the investment’s fair value in OCI. This election is made on an investment by investment basis. All financial assets not classified as measured at amortized cost or FVTOCI as described above are measured at FVTPL. The following accounting policies apply to the subsequent measurement of the Company’s financial assets: • • Financial liabilities are initially measured at fair value. Financial liabilities are classified as amortized cost or FVTPL. Financial liabilities that are classified as amortized cost are measured and recorded at amortized cost in accordance with the effective interest method. Financial liabilities classified as FVTPL are subsequently measured at fair value with changes in fair value recorded in the consolidated statement of income (loss) as part of the gain (loss) on changes in fair value of financial instruments. The Company has used derivative financial instruments to manage its exposure to foreign exchange risk associated with debt denominated in foreign currencies, as well as to reduce its exposure to interest rate risk associated with debt. Currently, the Company does not designate any of its derivative financial instruments as hedging instruments for accounting purposes. All realized and unrealized gains and losses on these derivative financial instruments are recorded in the consolidated statement of income (loss) as part of gain (loss) on changes in fair value of financial instruments. Derivatives, including embedded derivatives that must be separately accounted for, are recorded at fair value on the consolidated balance sheet at inception and marked to market at each reporting period thereafter. Derivatives embedded in financial liabilities and other non -financial -financial Transaction costs for instruments classified as FVTPL are expensed as incurred. Transaction costs that are directly attributable to the acquisition of financial assets and liabilities (other than FVTPL) are added or deducted from the fair value of the financial asset or financial liability on initial recognition. The Company’s financial assets classified as amortized cost and contract assets are subject to impairment requirements. The Company has elected to measure loss allowances for trade receivables and other contract assets at an amount equal to lifetime expected credit loss. The lifetime expected credit losses are the expected credit losses that result from possible default events over the expected life of the instrument. Financing Costs The debt issuance costs related to the Senior Secured Credit Facility, the 6.5% Senior Unsecured Notes (“Senior Unsecured Notes”), the 4.875% Senior Secured Notes (“Senior Secured Notes”) and the 5.625% Senior Secured Notes (“2026 Senior Secured Notes”) are included in current and long -term -term -term -term -line Employee Benefit Plans Telesat Canada maintains one contributory and three non -contributory -benefit Telesat Canada also provides other post -employment In addition, Telesat Canada provides defined contribution pension plans, under certain circumstances, for employees who are not eligible for the defined benefit pension plans. Telesat also provides health care and life insurance benefits for certain retired employees. These benefits are funded primarily on a pay -as-you-go -insurance As a result of the Transaction, the Company has become responsible for the defined benefit plan and health and life insurance benefits for retired employees of Loral. Loral maintained a defined benefit pension plan for its employees. Loral pension plan is a qualified defined benefit pension plan in which only the employees hired prior to July 1, 2006 could participate. Benefits are based primarily on members’ compensation and/or years of service. In addition to pension plan, certain health care and life insurance benefits are also provided to retired employees and dependents. Healthcare benefits end when the retiree reaches age 65. The Company is responsible for adequately funding the defined benefit pension plans. Contributions are made based on actuarial cost methods that are permitted by pension regulatory bodies and reflect assumptions about future investment returns, salary projections and future service benefits. Costs for defined contribution pension plans are recognized as an expense during the year in which the employees have rendered service entitling them to the Company’s contribution. The Company accrues the present value of its obligations under employee benefit plans and the related costs reduced by the fair value of plan assets. Pension costs and other retirement benefits are determined using the projected unit credit method prorated on service and management’s best estimate of expected investment performance, salary escalation, retirement ages of employees and expected health care costs. Pension plan assets are valued at fair value. The discount rate is based on the market interest rate of high quality bonds. Past service costs arising from plan amendments are recognized immediately to the extent that the benefits are already vested, and otherwise are amortized on a straight -line Remeasurements arising from defined benefit pension plans comprise actuarial gains and losses and the return on plan assets (excluding interest). The Company recognizes them immediately in other comprehensive income (loss), which is included in accumulated earnings, in the year in which they occur. The current service costs and administration fees not related to asset management are included in operating expenses. The net interest expense (income) on the net defined benefit liability (asset) for the period is calculated by applying the discount rate used to measure the defined benefit obligation at the beginning of the year to the net defined benefit liability (asset) at the beginning of the year while taking into account any changes in the net defined benefit liability (asset) during the year as a result of contributions and benefit payments. The net interest expense (income) is included in interest expense. Share-Based Compensation Plans The Company offers equity -settled -based -Scholes Restricted Share Units, Performance Share Units and Deferred Share Units For each restricted share unit (“RSU”), performance share unit (“PSU”) or deferred share unit (“DSU”) an expense is recorded over the vesting period equal to the fair value of the Non -Voting Income Taxes Income tax expense, comprised of current and deferred income tax, is recognized in income except to the extent it relates to items recognized in other comprehensive income (loss) or equity, in which case the income tax expense is recognized in other comprehensive income (loss) or equity, respectively. Current income tax is measured at the amount expected to be paid to the taxation authorities, net of recoveries, based on the tax rates and laws enacted or substantively enacted as at the balance sheet date. Deferred taxes are the result of temporary differences arising between the tax bases of assets and liabilities and their carrying amount. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period when the asset is realized or the liability is settled, based on tax rates and laws that have been enacted or substantively enacted at the balance sheet date. Deferred tax assets are recognized for all deductible temporary differences to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilized. The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that the deferred tax assets will be realized. Unrecognized deferred tax assets are reassessed at each balance sheet date and recognized to the extent that it has become probable that future taxable profit will allow the deferred tax assets to be recovered. Deferred tax assets are netted against the deferred tax liabilities when they relate to income taxes levied by the same taxation authority on either: i) ii) Deferred tax liabilities are recognized for all taxable temporary differences except when the deferred tax liability arises from the initial recognition of goodwill or the initial recognition of an asset or liability in a transaction which is not a business combination. For taxable temporary differences associated with investments in subsidiaries, a deferred tax liability is recognized unless the parent can control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future. Earnings Per Share For periods prior to the close of the Transaction, basic earnings per share are computed based upon the weighted average number of Common Shares, Non -Voting -controlling For periods subsequent to the close of the Transaction, basic earnings per share are computed based upon the weighted average number of Class A Common Shares, Class B Variable Voting Shares, Class C Fully Voting Shares and Class C Limited Voting Shares during each period. Variable Voting and Limited Voting shares are in all respects identical to and treated equally to voting common shares. For periods prior to the close of the Transaction, diluted earnings per share are based on the weighted average number of common shares as calculated in the basic earnings per share, adjusted for the effect of unvested or unconverted RSUs and stock options that have a dilutive effect. The average market value of the Company’s shares for the purpose of calculating the dilutive effect of the stock options was based on calculated share price of the shares of Telesat Canada, adjusted to take into account the impact of the Transaction. For periods subsequent to the close of the Transaction, diluted earnings per share are based on the weighted average number of Class A Common Shares, Class B Variable Voting Shares, Class C Fully Voting Shares and Class C Limited Voting Shares during each period, adjusted for the effect of unvested or unconverted RSUs, PSUs, DSUs and stock options which have a dilutive effect. For 2021, the average market value of the Company’s shares for the purposes of calculating the dilutive effect of the stock options was based on the quoted market prices for the period from November 19, 2021 through December 31, 2021. Non-Controlling Interests Non -controlling -controlling -controlling an acquisition -by-acquisition -controlling -controlling -controlling The Company reports non -controlling -controlling -controlling -controlling -controlling Future Changes in Accounting Policies The IASB periodically issues new and amended accounting standards. The new and amended standards determined to be applicable to the Company are disclosed below. The remaining new and amended standards have been excluded as they are not applicable. Amendments to IAS 1 and IFRS Practice Statement 2 In February 2021, the IASB issued amendments to IAS 1, Presentation of Financial Statements The amendments clarify that accounting policy information is material if users of an entity’s financial statements would need it to understand other material information in the financial statements and that accounting policy information may be material because of its nature, even if the related amounts are immaterial. On the other hand, although a transaction, other event or condition to which the accounting policy information relates may be material, it does not necessarily mean that the corresponding accounting policy information is material to the entity’s financial statements. The amendments are applied prospectively and are effective for annual periods beginning on or after January 1, 2023. The changes will only impact the level of disclosures within our financial statements. Amendments to IAS 12 In May 2021, the IASB issued amendments to IAS 12, Income Taxes In specified circumstances, companies are exempt from recognizing deferred tax when they recognize assets or liabilities for the first time. The amendments clarify that such initial recognition exemption does not apply to transactions in which equal amounts of deductible and taxable temporary differences arise on initial recognition. Accordingly, entities are required to recognize deferred tax associated with transactions, such as leases and decommissioning obligations, which give rise to equal and offsetting temporary differences. The amendments are effective for annual reporting periods beginning on or after January 1, 2023. There will be no impact on the Company’s consolidated financial statements as a result of the amendments. Amendments to IAS 1 In October 2022, IASB amended IAS 1 with the aim of improving the information companies provide about long -term The amendments specify that covenants to be complied with after the reporting date do not affect the classification of debt as current or non -current -current The amendments are effective for annual reporting periods beginning on or after January 1, 2024 with early adoption permitted. The Company is currently evaluating the impact of the amendment.

Critical Accounting Judgments and Estimates [Abstract]
CRITICAL ACCOUNTING JUDGMENTS AND ESTIMATES	5. CRITICAL ACCOUNTING JUDGMENTS AND ESTIMATES Critical judgments in applying accounting policies The following are the critical judgments made in applying the Company’s accounting policies which have the most significant effect on the amounts reported in the financial statements: Deferred revenue The Company’s accounting policy relating to deferred revenue is described in Note 4. Certain of the Company’s revenue agreements were noted to include a significant financing component. Judgment by management is required to determine the discount rate used in the significant financing component calculation. Lease liabilities The Company’s accounting policy relating to leases is described in Note 4. Judgment by management is required in the determination of the likelihood that the lease renewal periods will be exercised as well as the determination of the incremental borrowing rate. Uncertain income tax positions The Company operates in numerous jurisdictions and is subject to country -specific Software as a service arrangements The Company’s accounting policy relating to SaaS is described in Note 4. Judgment by management is required to determine whether configuration or customization of a software results in an intangible asset for Telesat. Critical accounting estimates and assumptions The Company makes accounting estimates and assumptions that affect the carrying value of assets and liabilities, reported net income (loss) and disclosure of contingent assets and liabilities. Estimates and assumptions are based on historical experience, current events and other relevant factors, therefore, actual results may differ and differences could be material. The accounting estimates and assumptions critical to the determination of the amounts reported in the financial statements were as follows: Derivative financial instruments measured at fair value Derivative financial assets and liabilities measured at fair value were $1.0 million and $5.4 million, respectively, as at December 31, 2021. The derivative assets and liabilities had a value of $ Nil Quoted market values are unavailable for the Company’s financial instruments and, in the absence of an active market, the Company determines fair value for financial instruments based on prevailing market rates (bid and ask prices, as appropriate) for instruments with similar characteristics and risk profiles or internal or external valuation models, such as option pricing models and discounted cash flow analysis, using observable market -based Impairment of goodwill Goodwill represented $2,446.6 million of total assets as at December 31, 2022 and 2021. Determining whether goodwill is impaired requires an estimation of the Company’s value which requires management to estimate the future cash flows expected to arise from operations and to make assumptions regarding economic factors, tax rates and annual growth rates. Actual operating results and the related cash flows of the Company could differ from the estimates used for the impairment analysis. Impairment of intangible assets Intangible assets represented $756.9 million of total assets as at December 31, 2022 (December 31, 2021 — $762.7 million). Impairment of intangible assets is tested annually or more frequently if indicators of impairment or reversal of a prior impairment loss exist. The impairment analysis requires the Company to estimate the future cash flows expected to arise from operations and to make assumptions regarding economic factors, discount rates, tax rates and annual growth rates. Significant judgments are made in establishing these assumptions. Actual operating results and the related cash flows of the Company could differ from the estimates used for the impairment analysis. Employee benefits The cost of defined benefit pension plans and other post -employment -term Share-based compensation The expense for stock options is based on the fair value of the awards granted using the Black -Scholes -Scholes -free Determination of useful life of satellites and finite life intangible assets The estimated useful life and depreciation method for satellites and finite life intangible assets are reviewed annually, with the effect of any changes in estimate being accounted for on a prospective basis. Any change in these estimates may have a significant impact on the amounts reported. Income taxes Management assesses the recoverability of deferred tax assets based upon an estimation of the Company’s projected taxable income using enacted or substantively enacted tax laws, and its ability to utilize future tax deductions before they expire. Actual results could differ from expectations.

They are limited in availability and represent a scarce resource. Usage of orbital slots is licensed through the International Telecommunications Union. Satellite operators can generally expect, with a relatively high level of certainty, continued occupancy of an assigned orbital slot either during the operational life of an existing orbiting satellite or upon replacement by a new satellite once the operational life of the existing orbiting satellite is over. As a result of the expectancy right to maintain the once awarded orbital slots, an indefinite life is typically associated with orbital slots. The Company’s trade name has a long and established history, a strong reputation and has been synonymous with quality and growth within the satellite industry. It has been assigned an indefinite life because of expected ongoing future use. The Company’s intellectual property relates to development relating to its planned Telesat Lightspeed constellation. It has been assigned an indefinite life because of anticipated ongoing future use. The following are the remaining useful lives of the intangible assets: Years Revenue backlog 2 Customer relationships 4 to 6 Customer contracts 4 Transponder rights 1 Concession rights 1 to 15 Software 3 Patent 3 All of the Company’s intangible assets, excluding the intangible assets held in unrestricted subsidiaries, have been pledged as security as a requirement of the Company’s Senior Secured Credit Facilities, Senior Secured Notes and 2026 Senior Secured Notes (Note 24). Impairment Finite life intangible assets are assessed for impairment at the Company’s CGU level. With the exception of trade name, which is tested for impairment at the asset level, the indefinite life intangible assets are tested for impairment at the individual CGU level. In the case of orbital slots, the CGU is based on geography. The annual impairment tests for these assets were performed in the fourth quarters of 2022 and 2021 in accordance with the policy described in Note 4. Orbital slots The orbital slots were valued using an income approach. The income approach is most sensitive to the following assumptions: • • • Movements in the underlying business plan The business plans reflect the most up -to-date • • • Discount rates Discount rates reflect management’s estimates of the specific risks. Management uses a weighted average cost of capital as a discount rate. The discount rates used was 9.0% in 2022 and 7.5% in 2021. Growth rate assumptions Growth rate assumptions used to extrapolate the cash flows beyond the business planning period are based on commercial experience and the expectations for the development of the markets which they serve. Trade name Relief from royalty method was used to calculate the fair value of the Telesat trade name. The relief from royalty analysis requires determining a hypothetical royalty rate and subsequent application of the rate to projected revenue. The relief from royalties method is most sensitive to the following assumptions: • • • • Movements in the underlying business plan The business plans reflect the most up -to-date Royalty rate The determination of the hypothetical royalty rate used in the relief from royalty approach will consider comparable license agreements and other qualitative factors. The royalty rate used for 2022 and 2021 was 0.25% of revenue. Discount rates Discount rates reflect management’s estimates of the specific risks. Management uses a weighted average cost of capital as a discount rate. The discount rates used was the following: 2022 2021 GEO royalties 9.0 % 7.5 % LEO royalties 17.5 % 17.5 % Growth rate assumptions Growth rate assumptions used to extrapolate the cash flows beyond the business planning period are based on commercial experience and the expectations for the development of the markets which they serve. The long -term 2022 2021 GEO — % — % LEO 2.0 % 3.0 % No impairment loss was recognized in the years ended December 31, 2022 and 2021. Some of the more sensitive assumptions used in the quantitative analysis, including the forecasted cash flows and the discount rate, could have yielded different estimates of the recoverable amount. Actual operating results and the related cash flows of the Company could differ from the estimated operating results and related cash flows used in the impairment analysis, and had different estimates been used, it could have resulted in a different fair value.

Goodwill [Abstract]
GOODWILL	18. GOODWILL The Company carries goodwill at its cost of $2,446.6 million with no accumulated impairment losses since acquisition. Impairment Goodwill is tested for impairment at the entity level because that represents the lowest level at which goodwill supports the Company’s operations and is monitored internally. The annual impairment test on goodwill was performed in the fourth quarters of 2022 and 2021 in accordance with the policy described in Note 4. In 2022 and 2021, the Company’s recoverable amount exceeded the carrying value therefore, no impairment was recognized. The calculation of the recoverable amount is most sensitive to the following assumptions: • • • Movements in the underlying business plan The business plans reflect the most up -to-date • • • Discount rates Discount rates reflect management’s estimates of the specific risks. Management uses a weighted average cost of capital as a discount rate. The discount rates used in the calculation are presented below: 2022 2021 GEO 9.0 % 7.5 % LEO 17.5 % 17.5 % U.S. C-band clearing proceeds 9.0 % 7.5 % Growth rate assumptions Growth rate assumptions used to extrapolate the cash flows beyond the business planning period are based on commercial experience and the expectations for the development of the markets which they serve. Growth rate assumptions were built into the GEO and LEO calculations. Some of the more sensitive assumptions used in the quantitative analysis, including the forecasted cash flows, discount rate and market multiples, could have yielded different estimates of the recoverable amount. Actual operating results and the related cash flows of the Company could differ from the estimated operating results and related cash flows used in the impairment analysis, and had different estimates been used, it could have resulted in a different fair value.

The Senior Secured Credit Facilities, have two tranches which are described below: (i) (ii) Debt issue costs of $16.0 million were incurred in connection with this amendment, inclusive of $1.3 million relating to the revolving credit facility. As at December 31, 2022, the debt costs had a carrying value of $8.6 million (December 31, 2021 — $10.6 million). The Senior Secured Credit Facilities are secured by substantially all of Telesat Canada’s assets, excluding those in the unrestricted subsidiaries. All obligations under the Credit Agreement are guaranteed by the Company and certain of Telesat Canada’s existing subsidiaries (“Guarantors”). The obligations under the Credit Agreement and the guarantees of those obligations are secured, subject to certain exceptions, by first priority liens and security interest in the assets of Telesat Canada and the Guarantors. The Credit Agreement contains total leverage ratio covenants that restrict, with certain exceptions, the ability of Telesat Canada and the Guarantors to take specified actions, including, among other things and subject to certain significant exceptions: creating liens, incurring indebtedness, making investments, engaging in mergers, selling property, paying dividends, entering into sale -leaseback In December 2020, the Company made a US$341.4 million prepayment on the Term Loan B — U.S. Facility. The prepayment was applied to all mandatory future quarterly principal repayments, with the remaining balance of the prepayment being applied towards the principal amount outstanding on maturity. The prepayment resulted in the recognition of a loss of $2.3 million, which was recorded against interest and other income and indebtedness. The loss recorded against the indebtedness is subsequently amortized to interest expense using the effective interest method and had a carrying value of $1.6 million as at December 31, 2022 (December 31, 2021 — $1.9 million). The weighted average effective interest rate for the year ended December 31, 2022 was 4.64% (December 31, 2021 — 2.96%). Senior Unsecured Notes On October 11, 2019, Telesat Canada issued, through a private placement, US$550 million of 6.5% Senior Unsecured Notes which mature in October 2027.

FINANCIAL INSTRUMENTS	30. FINANCIAL INSTRUMENTS Measurement of Risks The Company, through its financial assets and liabilities, is exposed to various risks. The following analysis provides a measurement of risks as at December 31, 2022. Credit risk Credit risk is the risk that a counterparty to a financial asset will default, resulting in the Company incurring a financial loss. As at December 31, 2022, the maximum exposure to credit risk is equal to the carrying value of the financial assets which totaled $1,730.0 million (December 31, 2021 — $1,589.5 million). The following table provides breakdown by maturity of financial assets as at December 31, 2022: Carrying amount Contractual cash flows 2023 2024 2025 2026 2027 Thereafter Cash and cash equivalents $ 1,677,792 $ 1,677,792 $ — $ — $ — $ — $ — Trade and other receivables, excluding deferred receivables 36,210 36,210 — — — — — Deferred receivables 13,931 5,038 3,295 1,303 1,354 644 2,297 Other financial assets 2,098 1,282 — — — — 816 $ 1,730,031 $ 1,720,322 $ 3,295 $ 1,303 $ 1,354 $ 644 $ 3,113 Cash and cash equivalents are invested with high quality investment grade financial institutions and are governed by the Company’s corporate investment policy, which aims to reduce credit risk by restricting investments to high -grade The Company has credit evaluation, approval and monitoring processes intended to mitigate potential credit risks related to trade accounts receivable. The Company’s standard payment terms are 30 days with interest typically charged on balances remaining unpaid at the end of standard payment terms. The Company’s historical experience with customer defaults has been minimal. As at December 31, 2022, North American and International customers made up 48% and 52% of the outstanding trade receivable balance, respectively (December 31, 2021 — 54% and 46%, respectively). Anticipated bad debt losses have been provided for in the allowance for doubtful accounts. The allowance for doubtful accounts as at December 31, 2022 was $4.9 million (December 31, 2021 — $5.2 million). The Company mitigates the credit risk associated with derivative instruments by entering into them with only high quality financial institutions. Foreign exchange risk The Company’s operating results are subject to fluctuations as a result of exchange rate variations to the extent that transactions are made in currencies other than Canadian dollars. The Company’s main currency exposures lie in its U.S. dollar denominated cash and cash equivalents, trade and other receivables, trade and other payables and indebtedness with the most significant impact being on the U.S. dollar denominated indebtedness, cash and short -term As at December 31, 2022, the impact of a 5 percent increase (decrease) in the value of the U.S. dollar against the Canadian dollar on financial assets and liabilities would have decreased (increased) net income (loss) by $172.1 million (December 31, 2021 — $174.0 million) and increased (decreased) other comprehensive income (loss) by $57.5 million (December 31, 2021 — $57.0 million). This analysis assumes that all other variables, in particular interest rates, remain constant. Interest rate risk The Company is exposed to interest rate risk on its cash and cash equivalents and its indebtedness. The interest rate risk on the indebtedness is from a portion of the indebtedness having a variable interest rate. Changes in the interest rates could impact the amount of interest that the Company is required to pay or receive. In October 2017, the Company entered into four interest rate swaps to hedge the interest rate risk associated with the variable interest rate on US$1,800.0 million of the U.S. denominated Term Loan B at fixed interest rates, excluding applicable margins, ranging from 1.72% to 2.04%. As at December 31, 2021, one interest rate swap of US$450 million, was outstanding to hedge the interest rate risk associated with the variable interest rate on the U.S. denominated Term Loan B at fixed interest rate, excluding applicable margins, of 2.04%. This interest rate swap matured in September 2022. There are no outstanding interest rate swaps as at December 31, 2022. If the interest rates on the variable rate indebtedness change by 0.25%, the result would be an increase or decrease to net income (loss) of $4.3 million for the year ended December 31, 2022 (December 31, 2021 — $4.9 million). Liquidity risk The Company maintains credit facilities to ensure it has sufficient funds available to meet current and foreseeable financial requirements. The contractual maturities of financial liabilities as at December 31, 2022 were as follows: Carrying Contractual 2023 2024 2025 2026 2027 Thereafter Trade and other payables $ 43,555 $ 43,555 $ 43,555 $ — $ — $ — $ — $ — Customer and other deposits 1,541 1,541 1,062 104 221 — — 154 Satellite performance incentive payments 25,457 30,989 8,092 5,660 3,337 3,399 2,515 7,986 Other financial liabilities 2,859 2,859 2,859 — — — — — Indebtedness (1) 3,891,354 4,926,376 278,498 253,278 251,912 3,024,348 1,118,340 — $ 3,964,766 $ 5,005,320 $ 334,066 $ 259,042 $ 255,470 $ 3,027,747 $ 1,120,855 $ 8,140 ____________ (1) The interest payable and interest payments included in the carrying value and contractual cash flows, respectively, in the above table, were as follows: Interest Interest Satellite performance incentive payments $ 333 $ 5,862 Indebtedness $ 38,203 $ 1,073,225 Financial assets and liabilities recorded on the balance sheets and the fair value hierarchy levels used to calculate those values were as follows: As at December 31, 2022 FVTPL Amortized Total Fair Fair value Cash and cash equivalents $ — $ 1,677,792 $ 1,677,792 $ 1,677,792 Level 1 Trade and other receivables — 41,248 41,248 41,248 (1) Other current financial assets — 515 515 515 Level 1 Other long-term financial assets — 10,476 10,476 10,476 Level 1 Trade and other payables — (43,555 ) (43,555 ) (43,555 ) (1) Other current financial liabilities — (48,397 ) (48,397 ) (49,500 ) Level 2 Other long-term financial liabilities — (19,663 ) (19,663 ) (19,164 ) Level 2 Indebtedness (2) — (3,853,151 ) (3,853,151 ) (1,684,897 ) Level 2 $ — $ (2,234,735 ) $ (2,234,735 ) $ (67,085 ) As at December 31, 2021 FVTPL Amortized Total Fair Fair value Cash and cash equivalents $ — $ 1,449,593 $ 1,449,593 $ 1,449,593 Level 1 Trade and other receivables — 122,698 122,698 122,698 ​ (1) Other current financial assets — 861 861 861 Level 1 Other long-term financial assets (3) 1,038 15,310 16,348 16,348 Level 1, Level 2 Trade and other payables — (54,628 ) (54,628 ) (54,628 ) (1) Other current financial liabilities (5,367 ) (31,280 ) (36,647 ) (38,250 ) Level 2 Other long-term financial liabilities — (23,835 ) (23,835 ) (24,240 ) Level 2 Indebtedness (2) — (3,794,657 ) (3,794,657 ) (3,314,387 ) Level 2 $ (4,329 ) $ (2,315,938 ) $ (2,320,267 ) $ (1,842,005 ) ____________ (1) -term (2) (3) -term Assets pledged as security The Senior Secured Credit Facilities, Senior Secured Notes and 2026 Senior Secured Notes are secured by substantially all of Telesat’s assets excluding the assets of unrestricted subsidiaries. Fair Value Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market under current market conditions at the measurement date. Where possible, fair values are based on the quoted market values in an active market. In the absence of an active market, the Company determines fair values based on prevailing market rates (bid and ask prices, as appropriate) for instruments with similar characteristics and risk profiles or internal or external valuation models, such as option pricing models and discounted cash flow analysis, using observable market -based The fair value hierarchy is as follows: Level 1 is based on quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company can access at the measurement date. Level 2 is based on observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially all of the full term of the assets or liabilities. Level 3 is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Estimates of fair values are affected significantly by the assumptions for the amount and timing of estimated future cash flows and discount rates, which all reflect varying degrees of risk. Potential income taxes and other expenses that would be incurred on disposition of these financial instruments are not reflected in the fair values. As a result, the fair values are not necessarily the net amounts that would be realized if these instruments were actually settled. The carrying amounts of cash and cash equivalents, trade and other receivables, and trade and other payables approximate fair value due to the short -term -term The fair value of the satellite performance incentive payments, included in other current and long -term The fair value of the indebtedness was based on transactions and quotations from third parties considering market interest rates and excluding deferred financing costs, prepayment options and loss on repayment. The calculation of the fair value of the indebtedness is performed on a recurring basis. The rates used were as follows: As at December 31 2022 2021 Term Loan B – U.S. Facility – Senior Secured Credit Facilities 45.63 % 88.25 % Senior Unsecured Notes 29.90 % 77.65 % Senior Secured Notes 45.71 % 88.72 % 2026 Senior Secured Notes 47.02 % 94.09 % Fair value of derivative financial instruments Derivatives were valued using a discounted cash flow methodology. The calculations of the fair value of the derivatives are performed on a recurring basis. For December 31, 2021, interest rate swap future cash flows were determined based on current yield curves and exchange rates and then discounted based on discount curves. There were no interest rate swaps outstanding as of December 31, 2022. Prepayment option cash flows were calculated with a third party option valuation model which is based on the current price of the debt instrument and discounted based on a discount curve.

EMPLOYEE BENEFIT PLANS	32. EMPLOYEE BENEFIT PLANS The Company maintains defined benefit pension plans for Telesat Canada employees (“Canadian Pension Plans”). In October 2013, the Company ceased to allow new employees to join certain defined benefit plans, except under certain circumstances, and commenced a defined contribution pension plan for new employees. On completion of the Transaction, the Company also took over the defined benefit pension plans for certain former employees of Loral (“US Pension Plans”). Under the US Pension Plans, certain former Loral employees hired prior to July 1, 2006 contributed until November 18, 2021 in order to receive enhanced pension benefits.

Plan assets are represented primarily by equity securities, fixed income instruments and short -term The defined benefit plans typically expose the Company to actuarial risks such as investment risk, interest rate risk, longevity risk and salary risk. Investment risk is managed by specifying allowable investment types, setting diversification strategies and determining target asset allocations.

The total outstanding commitments as at December 31, 2022 were included in capital commitments. The Company has agreements with various customers for prepaid revenue on several service agreements which take effect when the satellite is placed in service. The Company is responsible for operating and controlling these satellites. As at December 31, 2022, customer prepayments of $326.4 million (December 31, 2021 — $368.1 million), a portion of which is refundable under certain circumstances, were reflected in other current and long -term In the normal course of business, the Company has executed agreements that provide for indemnification and guarantees to counterparties in various transactions. These indemnification undertakings and guarantees may require the Company to compensate the counterparties for costs and losses incurred as a result of certain events including, without limitation, loss or damage to property, change in the interpretation of laws and regulations (including tax legislation), claims that may arise while providing services, or as a result of litigation that may be suffered by the counterparties. The nature of substantially all of the indemnification undertakings prevents the Company from making a reasonable estimate of the maximum potential amount the Company could be required to pay counterparties as the agreements do not specify a maximum amount and the amounts are dependent upon the outcome of future contingent events, the nature and likelihood of which cannot be determined at this time. Historically, the Company has not made any significant payments under such indemnifications. Telesat Corporation and Telesat CanHold Corporation have entered into an indemnification agreement with PSP Investments where they will indemnify PSP Investments on a grossed -up -of-pocket In the case of indemnification for certain tax matters only, there will be a cap of US$50 million (other than with respect to defense costs and grossed -up Legal Proceedings The Company participates from time to time in legal proceedings arising in the normal course of its business. Telesat previously received assessments from Brazilian tax authorities alleging that additional taxes are owed on revenue earned for the period 2003 to 2018. The total disputed amount for the period 2003 to 2018, including interest and penalties, is now $89.6 million. The disputes relate to the Brazilian tax authorities’ characterization of revenue. The Company has challenged the assessments. The Company believes the likelihood of a favorable outcome in these disputes is more likely than not and, as such, no reserve has been established. The Canadian tax authorities previously reassessed the Company for $13.1 million relating to transfer pricing issues for the years 2009 to 2014. All disputes relate to the Canadian tax authorities’ repricing of certain transactions between the Company and its subsidiaries. The Company has challenged the reassessments and paid 50% of the outstanding amounts in order to formally object. The Company believes the likelihood of a favorable outcome in these disputes is more likely than not and, as such, no reserve has been established. The Canadian tax authorities have also reassessed the Company for $11.6 million relating to its Scientific Research and Experimental Development claims for the years 2016 and 2017. The Company has challenged the reassessments and paid 50% of the outstanding amounts in order to formally object. The Company believes the likelihood of a favorable outcome in these disputes is more likely than not and, as such, no reserve has been established. Other than the legal proceedings disclosed above, the Company is not aware of any proceedings outstanding or threatened as of the date hereof by or against it or relating to its business which may have, or have had in the recent past, significant effects on the Company’s financial position or profitability.

Segment Reporting	Segment Reporting The Company operates in a single operating segment, in which it provides satellite -based
Foreign Currency Translation	Foreign Currency Translation Unless otherwise specified, all figures reported in the consolidated financial statements and associated note disclosures are presented in Canadian dollars, which is the functional and presentation currency of the Company. Each of the subsidiaries of the Company determines its own functional currency and uses that currency to measure items on their separate financial statements. For the Company’s non -foreign -monetary Upon consolidation of the Company’s foreign operations that have a functional currency other than the Canadian dollar, assets and liabilities are translated at the year end exchange rate, and revenue and expenses are translated at the average exchange rates of the month in which the transactions occurred. Gains or losses on the translation of foreign subsidiaries are recognized in other comprehensive income (loss).
Cash and Cash Equivalents	Cash and Cash Equivalents All highly liquid investments with an original maturity of three months or less, or which are available upon demand with no penalty for early redemption, are classified as cash and cash equivalents. Cash and cash equivalents are comprised of cash on hand, demand deposits, short -term
Software as a service arrangements	Revenue Recognition Telesat recognizes revenue from satellite services on a monthly basis as services are performed in an amount that reflects the consideration the Company expects to receive in exchange for those services. Telesat accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability is considered probable. Revenue from a contract to sell consulting services is recognized as follows: • • Equipment sale revenue is recognized when the customer obtains control of the equipment, being at the time the equipment is delivered to and accepted by the customer. Only equipment sales are subject to warranty or return and there is no general right of return. Historically, the Company has not incurred significant expenses for warranties. When a transaction involves more than one product or service, revenue is allocated to each performance obligation based on its relative stand -alone
Deferred Revenue	Deferred Revenue Deferred revenue represents the Company’s liability for the provision of future services and is classified on the balance sheet in other current and long -term -line -term A significant financing component will only occur in the following circumstances: • • • In the case of the existence of a significant financing component, the amount of the consideration is adjusted to reflect what the cash selling price of the promised service would have been if payments had occurred as control of the service was transferred to the customer. The discount rate used in determining the significant financing component is the rate that would be reflected in a separate financing transaction between the Company and the customer at contract inception.
Inventories	Inventories Inventories are valued at the lower of cost and net realizable value and consist of finished goods and work in process. Cost for substantially all network equipment inventories are determined on a weighted average cost basis. Cost for work in process and certain one -of-a-kind
Borrowing Costs	Borrowing Costs Borrowing costs are incurred on the Company’s debt financing. Borrowing costs attributable to the acquisition, production or construction of a qualifying asset are added to the cost of that asset. The Company has defined a qualifying asset as an asset that takes longer than twelve months to be ready for its intended use or sale. Capitalization of borrowing costs continues until such time that the asset is substantially ready for its intended use or sale. Borrowing costs are determined based on specific financing related to the asset, or in the absence of specific financing, the borrowing costs are calculated on the basis of a capitalization rate which is equal to the Company’s weighted average cost of debt. All other borrowing costs are expensed when incurred.
Leases	Leases At the inception of a contract, the Company assesses whether a contract is, or contains, a lease based on whether or not the contract conveys the right to control the use of the asset for a period of time in exchange for consideration. The Company recognizes a right -of-use -of-use -of-use The lease term is the non -cancellable After the commencement date, the right -of-use -line The lease liability is remeasured when there is a change in future lease payments, arising from a change in index or rate, or if there is a change in the assessment of whether the Company will exercise a purchase, extension or termination option. The amount of the remeasurement of the lease liability is also recognized as an adjustment to the right -of-use -of-use The Company has elected to not recognize a right -of-use -line The Company has also elected the practical expedient, for property leases, not to separate the non -lease -lease
Government Grants	Government Grants Government grants are recognized where there is a reasonable assurance that the grant will be received and the attached conditions will be complied with. When the grant relates to an expense, the grant is recorded as a deduction to the related expense incurred over the same period. When the grant relates to an asset, the grant is deducted from the carrying amount of the related asset as the grant is receivable.
Software as a service arrangements	Software as a service arrangements A SaaS cloud computing arrangement is evaluated as to whether it met the criteria under IAS Intangible Assets Leases Telesat may enter into a SaaS cloud computing arrangement with a supplier where the contract conveys to Telesat a right to receive future access over the contract term to the supplier’s application software running on the supplier’s cloud infrastructure. The right to receive access does not provide Telesat with a software asset and, therefore, the access to the software is a service which is received over the contract term. The assessment of whether configuration or customization of a software results in an intangible asset for Telesat depends on the nature and output of the configuration and customization performed. In some circumstances, the arrangement may result in additional code from which Telesat has the power to obtain the future economic benefits and to restrict others’ access to those benefits. In that case, in determining whether to recognise the additional code as an intangible asset, Telesat assesses whether the additional code is identifiable and meets the recognition criteria under IAS 38. Separately acquired intangible rights (i.e. software licenses in cloud computing arrangements) are normally recognized as assets.
Satellites, Property and Other Equipment	Satellites, Property and Other Equipment Satellites, property and other equipment, which are carried at cost, less accumulated depreciation and any accumulated impairment losses, include the contractual cost of equipment, capitalized engineering costs, capitalized borrowing costs during the construction or production of qualifying assets, and with respect to satellites, the cost of launch services, and launch insurance. Depreciation is calculated using the straight -line Below are the estimated useful lives in years of satellites, property and other equipment as at December 31, 2022. Years Satellites 12 to 15 Right-of-use assets 2 to 27 Antennas, satellite control & communication equipment 8 to 20 Building, equipment & other 3 to 25 Construction in progress is not depreciated as depreciation only commences when the asset is ready for its intended use. For satellites, depreciation commences on the day the satellite becomes available for service. The investment in each satellite will be derecognized from the accounts when the satellite is retired. When other property is retired from operations at the end of its useful life, the cost of the asset and accumulated depreciation are derecognized from the accounts. Earnings are credited with the amount of any net salvage value and charged with any net cost of removal. When an asset is sold prior to the end of its useful life, the gain or loss is recognized immediately in other operating gains (losses), net. In the event of an unsuccessful launch or total in -orbit -orbit Liabilities related to decommissioning and restoration of retiring property and other equipment are measured at fair value with a corresponding increase to the carrying amount of the related asset. The liability is accreted over the period of expected cash flows with a corresponding charge to interest expense. The liabilities recorded to date have not been significant and are reassessed at the end of each reporting period. There are no decommissioning or restoration obligations for satellites.
Satellite Performance Incentive Payments	Satellite Performance Incentive Payments Satellite performance incentive payments are obligations payable to satellite manufacturers over the lives of certain satellites. The present value of the payments are capitalized as part of the cost of the satellite and recognized as part of the depreciation of the satellite.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets Tangible fixed assets and finite life intangible assets are assessed for impairment on an annual basis or more frequently when events or changes in circumstances indicate that the carrying value of an asset exceeds the recoverable amount. Tangible fixed assets and finite life intangible assets are also assessed for indicators of impairment or impairment reversals at each reporting period. In cases where there are indicators of impairment, the recoverable amount of the asset, which is the higher of its fair value less costs of disposal and its value in use, is determined. If it is not possible to measure the recoverable amount for a particular asset, the Company determines the recoverable amount of the cash generating unit (“CGU”) with which it is associated. A CGU is the smallest identifiable group of assets that generates cash inflows which are largely independent of the cash inflows from other assets or groups of assets. The Company measures value in use on the basis of the estimated future cash flows to be generated by an asset or CGU. These future cash flows are based on the Company’s latest business plan information and are discounted using rates that best reflect the time value of money and the specific risks associated with the underlying asset or assets in the CGU. The fair value less costs of disposal is the price that would be received to sell an asset or CGU in an orderly transaction between market participants at the measurement date. For the impairment assessment, the fair value is calculated on a recurring basis and is calculated using level 3 of the fair value hierarchy. An impairment loss is the amount by which the carrying amount of an asset or CGU exceeds its recoverable amount. When an impairment loss subsequently reverses, the carrying amount of the asset (or a CGU) is increased to the revised measure of its recoverable amount, so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or CGU) in prior years. Impairment losses and reversals of impairment losses are recognized in other operating gains (losses), net.
Goodwill and Intangible Assets	Goodwill and Intangible Assets The Company accounts for business combinations using the acquisition method of accounting, which establishes specific criteria for the recognition of intangible assets separately from goodwill. Goodwill represents the excess between the total of the consideration transferred over the fair value of net assets acquired. After initial recognition at cost, goodwill is measured at cost less any accumulated impairment losses. The Company distinguishes intangible assets between assets with finite and indefinite useful lives. Intangible assets with indefinite useful lives are comprised of the Company’s trade name, intellectual property, and orbital slots. These assets are carried at cost less any accumulated impairment losses. Finite life intangible assets, which are carried at cost less accumulated amortization and any accumulated impairment losses, consist of revenue backlog, customer relationships, customer contracts, concession rights, transponder rights, software and patents. Intangible assets with finite lives are amortized over their estimated useful lives using the straight -line Below are the estimated useful lives in years of the finite life intangible assets as at December 31, 2022. Years Revenue backlog 17 Customer relationships 20 to 21 Customer contracts 15 Concession rights 5 to 15 Transponder rights 16 Software 5 Patents 18
Impairment of Goodwill and Indefinite Life Intangible Assets	Impairment of Goodwill and Indefinite Life Intangible Assets An assessment for impairment of goodwill and indefinite life intangible assets is performed annually, or more frequently whenever events or changes in circumstances indicate that the carrying amounts of these assets are likely to exceed their recoverable amount. Goodwill is tested for impairment at the entity level as this represents the lowest level within the Company at which the goodwill is monitored for internal management purposes, and is not larger than an operating segment. With the exception of trade name, which has not been allocated to any CGU and is tested for impairment at the asset level, indefinite life intangible assets are tested for impairment at the CGU level. In the case of orbital slots, the CGU is based on geography. A quantitative impairment test consists of assessing the recoverable amount of an asset, which is the higher of its fair value less costs of disposal and its value in use. For the quantitative impairment assessment, fair value is calculated on a recurring basis and is calculated using level 2 or level 3 of the fair value hierarchy depending on the valuation approach being utilized. Orbital Slots In performing the orbital slot impairment analysis, the Company determines, for each CGU, the recoverable amount. The recoverable amount is defined as the higher of the fair value less costs of disposal, and its value in use on an annual basis. To the extent that the recoverable amount is less than the carrying value of the asset, an impairment exists and the asset is written down to its recoverable amount. Fair value less costs of disposal is the price that would be received to sell the CGU in an orderly transaction between market participants at the measurement date. In order to determine the fair value less costs of disposal, the Company uses either a market or income approach. Under a market approach, the Company measures what an independent third party would pay to purchase the orbital slots by looking to actual market transactions for similar assets. Under an income approach, the fair value is determined to be the sum of the projected discounted cash flows over a discrete period of time. The value in use amount is the present value of the future cash flows expected to be derived from the CGU. The determination of this amount includes projections of cash inflows from the continuing use of the asset and cash outflows that are required to generate the associated cash inflows. These cash flows are discounted at an appropriate discount rate. Goodwill In performing the goodwill impairment analysis, the Company assesses the recoverable amount of goodwill. The recoverable amount is the higher of the income approach as well as the market approach in the determination of the fair value of goodwill at the entity level. Under the income approach, the sum of the projected discounted cash flows for the next five years, or a longer period if justified by the most recent financial plan approved by management, in addition to a terminal value are used to determine the fair value at the entity level. Under the market approach, the fair value at the entity level is determined based on market multiples derived from comparable public companies. Under both approaches, all assumptions used are based on management’s best estimates. The discount rates are consistent with external sources of information. Trade Name For the purposes of impairment testing, the fair value of the trade name is determined using an income approach, specifically the relief from royalties method. The relief from royalties method is comprised of two major steps: i) ii) In determining the hypothetical royalty rate in the relief from royalties method, the Company considered comparable license agreements, operating earnings benchmarks, an excess earnings analysis to determine aggregate intangible asset earnings, and other qualitative factors. Intellectual Property In performing the intellectual property impairment analysis, the Company determines its recoverable amount. The recoverable amount is the fair value less costs of disposal. To the extent that the recoverable amount is less than the carrying value of the asset, an impairment exists and the asset is written down to its recoverable amount. The Company measures value in use on the basis of the estimated future cash flows to be generated by an asset. These future cash flows are based on the Company’s latest business plan information approved by senior management and are discounted using rates that best reflect the time value of money and the specific risks associated with the underlying asset.
Financial Instruments	Financial Instruments Financial assets are initially recognized at fair value. Financial assets are measured using one of three measurement approaches (fair value through profit or loss (“FVTPL”), fair value through other comprehensive income (“FVTOCI”), or amortized cost). A financial asset is measured at amortized cost if it is not designated as FVTPL, it is held within a business model whose objective is to hold assets to collect contractual cash flows and its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. A debt investment is measured at FVTOCI if it is not designated at FVTPL, it is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets and its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amounts outstanding. On initial recognition of an equity investment that is not held for trading, the Company may irrevocably elect to present subsequent changes in the investment’s fair value in OCI. This election is made on an investment by investment basis. All financial assets not classified as measured at amortized cost or FVTOCI as described above are measured at FVTPL. The following accounting policies apply to the subsequent measurement of the Company’s financial assets: • • Financial liabilities are initially measured at fair value. Financial liabilities are classified as amortized cost or FVTPL. Financial liabilities that are classified as amortized cost are measured and recorded at amortized cost in accordance with the effective interest method. Financial liabilities classified as FVTPL are subsequently measured at fair value with changes in fair value recorded in the consolidated statement of income (loss) as part of the gain (loss) on changes in fair value of financial instruments. The Company has used derivative financial instruments to manage its exposure to foreign exchange risk associated with debt denominated in foreign currencies, as well as to reduce its exposure to interest rate risk associated with debt. Currently, the Company does not designate any of its derivative financial instruments as hedging instruments for accounting purposes. All realized and unrealized gains and losses on these derivative financial instruments are recorded in the consolidated statement of income (loss) as part of gain (loss) on changes in fair value of financial instruments. Derivatives, including embedded derivatives that must be separately accounted for, are recorded at fair value on the consolidated balance sheet at inception and marked to market at each reporting period thereafter. Derivatives embedded in financial liabilities and other non -financial -financial Transaction costs for instruments classified as FVTPL are expensed as incurred. Transaction costs that are directly attributable to the acquisition of financial assets and liabilities (other than FVTPL) are added or deducted from the fair value of the financial asset or financial liability on initial recognition. The Company’s financial assets classified as amortized cost and contract assets are subject to impairment requirements. The Company has elected to measure loss allowances for trade receivables and other contract assets at an amount equal to lifetime expected credit loss. The lifetime expected credit losses are the expected credit losses that result from possible default events over the expected life of the instrument.
Financing Costs	Financing Costs The debt issuance costs related to the Senior Secured Credit Facility, the 6.5% Senior Unsecured Notes (“Senior Unsecured Notes”), the 4.875% Senior Secured Notes (“Senior Secured Notes”) and the 5.625% Senior Secured Notes (“2026 Senior Secured Notes”) are included in current and long -term -term -term -term -line
Employee Benefit Plans	Employee Benefit Plans Telesat Canada maintains one contributory and three non -contributory -benefit Telesat Canada also provides other post -employment In addition, Telesat Canada provides defined contribution pension plans, under certain circumstances, for employees who are not eligible for the defined benefit pension plans. Telesat also provides health care and life insurance benefits for certain retired employees. These benefits are funded primarily on a pay -as-you-go -insurance As a result of the Transaction, the Company has become responsible for the defined benefit plan and health and life insurance benefits for retired employees of Loral. Loral maintained a defined benefit pension plan for its employees. Loral pension plan is a qualified defined benefit pension plan in which only the employees hired prior to July 1, 2006 could participate. Benefits are based primarily on members’ compensation and/or years of service. In addition to pension plan, certain health care and life insurance benefits are also provided to retired employees and dependents. Healthcare benefits end when the retiree reaches age 65. The Company is responsible for adequately funding the defined benefit pension plans. Contributions are made based on actuarial cost methods that are permitted by pension regulatory bodies and reflect assumptions about future investment returns, salary projections and future service benefits. Costs for defined contribution pension plans are recognized as an expense during the year in which the employees have rendered service entitling them to the Company’s contribution. The Company accrues the present value of its obligations under employee benefit plans and the related costs reduced by the fair value of plan assets. Pension costs and other retirement benefits are determined using the projected unit credit method prorated on service and management’s best estimate of expected investment performance, salary escalation, retirement ages of employees and expected health care costs. Pension plan assets are valued at fair value. The discount rate is based on the market interest rate of high quality bonds. Past service costs arising from plan amendments are recognized immediately to the extent that the benefits are already vested, and otherwise are amortized on a straight -line Remeasurements arising from defined benefit pension plans comprise actuarial gains and losses and the return on plan assets (excluding interest). The Company recognizes them immediately in other comprehensive income (loss), which is included in accumulated earnings, in the year in which they occur. The current service costs and administration fees not related to asset management are included in operating expenses. The net interest expense (income) on the net defined benefit liability (asset) for the period is calculated by applying the discount rate used to measure the defined benefit obligation at the beginning of the year to the net defined benefit liability (asset) at the beginning of the year while taking into account any changes in the net defined benefit liability (asset) during the year as a result of contributions and benefit payments. The net interest expense (income) is included in interest expense.

Income Taxes	Income Taxes Income tax expense, comprised of current and deferred income tax, is recognized in income except to the extent it relates to items recognized in other comprehensive income (loss) or equity, in which case the income tax expense is recognized in other comprehensive income (loss) or equity, respectively. Current income tax is measured at the amount expected to be paid to the taxation authorities, net of recoveries, based on the tax rates and laws enacted or substantively enacted as at the balance sheet date. Deferred taxes are the result of temporary differences arising between the tax bases of assets and liabilities and their carrying amount. Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the period when the asset is realized or the liability is settled, based on tax rates and laws that have been enacted or substantively enacted at the balance sheet date. Deferred tax assets are recognized for all deductible temporary differences to the extent that it is probable that taxable profit will be available against which the deductible temporary difference can be utilized. The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that the deferred tax assets will be realized. Unrecognized deferred tax assets are reassessed at each balance sheet date and recognized to the extent that it has become probable that future taxable profit will allow the deferred tax assets to be recovered. Deferred tax assets are netted against the deferred tax liabilities when they relate to income taxes levied by the same taxation authority on either: i) ii) Deferred tax liabilities are recognized for all taxable temporary differences except when the deferred tax liability arises from the initial recognition of goodwill or the initial recognition of an asset or liability in a transaction which is not a business combination. For taxable temporary differences associated with investments in subsidiaries, a deferred tax liability is recognized unless the parent can control the timing of the reversal of the temporary difference and it is probable that the temporary difference will not reverse in the foreseeable future.
Earnings Per Share	Earnings Per Share For periods prior to the close of the Transaction, basic earnings per share are computed based upon the weighted average number of Common Shares, Non -Voting -controlling For periods subsequent to the close of the Transaction, basic earnings per share are computed based upon the weighted average number of Class A Common Shares, Class B Variable Voting Shares, Class C Fully Voting Shares and Class C Limited Voting Shares during each period. Variable Voting and Limited Voting shares are in all respects identical to and treated equally to voting common shares. For periods prior to the close of the Transaction, diluted earnings per share are based on the weighted average number of common shares as calculated in the basic earnings per share, adjusted for the effect of unvested or unconverted RSUs and stock options that have a dilutive effect. The average market value of the Company’s shares for the purpose of calculating the dilutive effect of the stock options was based on calculated share price of the shares of Telesat Canada, adjusted to take into account the impact of the Transaction. For periods subsequent to the close of the Transaction, diluted earnings per share are based on the weighted average number of Class A Common Shares, Class B Variable Voting Shares, Class C Fully Voting Shares and Class C Limited Voting Shares during each period, adjusted for the effect of unvested or unconverted RSUs, PSUs, DSUs and stock options which have a dilutive effect. For 2021, the average market value of the Company’s shares for the purposes of calculating the dilutive effect of the stock options was based on the quoted market prices for the period from November 19, 2021 through December 31, 2021.

Future Changes in Accounting Policies	Future Changes in Accounting Policies The IASB periodically issues new and amended accounting standards. The new and amended standards determined to be applicable to the Company are disclosed below. The remaining new and amended standards have been excluded as they are not applicable. Amendments to IAS 1 and IFRS Practice Statement 2 In February 2021, the IASB issued amendments to IAS 1, Presentation of Financial Statements The amendments clarify that accounting policy information is material if users of an entity’s financial statements would need it to understand other material information in the financial statements and that accounting policy information may be material because of its nature, even if the related amounts are immaterial. On the other hand, although a transaction, other event or condition to which the accounting policy information relates may be material, it does not necessarily mean that the corresponding accounting policy information is material to the entity’s financial statements. The amendments are applied prospectively and are effective for annual periods beginning on or after January 1, 2023. The changes will only impact the level of disclosures within our financial statements. Amendments to IAS 12 In May 2021, the IASB issued amendments to IAS 12, Income Taxes In specified circumstances, companies are exempt from recognizing deferred tax when they recognize assets or liabilities for the first time. The amendments clarify that such initial recognition exemption does not apply to transactions in which equal amounts of deductible and taxable temporary differences arise on initial recognition. Accordingly, entities are required to recognize deferred tax associated with transactions, such as leases and decommissioning obligations, which give rise to equal and offsetting temporary differences. The amendments are effective for annual reporting periods beginning on or after January 1, 2023. There will be no impact on the Company’s consolidated financial statements as a result of the amendments. Amendments to IAS 1 In October 2022, IASB amended IAS 1 with the aim of improving the information companies provide about long -term The amendments specify that covenants to be complied with after the reporting date do not affect the classification of debt as current or non -current -current The amendments are effective for annual reporting periods beginning on or after January 1, 2024 with early adoption permitted. The Company is currently evaluating the impact of the amendment.

stock incentive plan, description				Under the stock incentive plans, two different types of stock options could be granted: time-vesting options and performance-vesting options. The time-vesting options generally become vested and exercisable over a five-year period by 20% annual increments. The performance-vesting options become vested and exercisable over a five-year period, provided that the Company has achieved or exceeded an annual or cumulative target consolidated EBITDA established by the Board of Directors. The exercise period of the stock options expires 10 years from the grant date. The exercise price of each share underlying the options will be the higher of a fixed price, established by the Board of Directors on the grant date, and the fair market value of a Non-Voting Participating Preferred Share on the grant date. Both plans authorized the Board of Directors to grant tandem SARs, at their discretion.
