Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited interim consolidated financial statements of Enbridge Inc. (“we”, “our”, “us” and “Enbridge”) have been prepared in accordance with generally accepted accounting principles in the United States of America (US GAAP) and Regulation S-X for interim consolidated financial information. They do not include all of the information and notes required by US GAAP for annual consolidated financial statements and should therefore be read in conjunction with our audited consolidated financial statements and notes for the year ended December 31, 2021. In the opinion of management, the interim consolidated financial statements contain all normal recurring adjustments necessary to present fairly our financial position, results of operations and cash flows for the interim periods reported. These interim consolidated financial statements follow the same significant accounting policies as those included in our audited consolidated financial statements for the year ended December 31, 2021, except for the adoption of new standards (Note 2) . Amounts are stated in Canadian dollars unless otherwise noted. Our operations and earnings for interim periods can be affected by seasonal fluctuations within the gas distribution utility businesses, as well as other factors such as supply of and demand for crude oil and natural gas, and may not be indicative of annual results. Certain comparative figures in our interim consolidated financial statements have been reclassified to conform to the current year's presentation.

CHANGES IN ACCOUNTING POLICIES

CHANGES IN ACCOUNTING POLICIES	9 Months Ended

Accounting Standards Update and Change in Accounting Principle [Abstract]
CHANGES IN ACCOUNTING POLICIES	CHANGES IN ACCOUNTING POLICIES ADOPTION OF NEW ACCOUNTING STANDARDS Disclosures About Government Assistance Effective January 1, 2022, we adopted Accounting Standards Update (ASU) 2021-10 on a prospective basis. The new standard was issued in November 2021 to increase the transparency of government assistance to business entities. The ASU adds new disclosure requirements for transactions with governments that are accounted for using a grant or contribution accounting model by analogy. The required disclosures include information about the nature of transactions, accounting policy applied, impacted financial statement line items and significant terms and conditions. The adoption of this ASU did not have a material impact on our consolidated financial statements. Accounting for Certain Lessor Leases with Variable Lease Payments Effective January 1, 2022, we adopted ASU 2021-05 on a prospective basis. The new standard was issued in July 2021 to amend lessor accounting for certain leases with variable lease payments that do not depend on a reference index or a rate and would have resulted in the recognition of a loss at lease commencement if classified as a sales-type or a direct financing lease. The ASU amends the classification requirements of such leases for lessors to result in an operating lease classification. The adoption of this ASU did not have a material impact on our consolidated financial statements. Accounting for Modifications or Exchanges of Certain Equity-Classified Contracts Effective January 1, 2022, we adopted ASU 2021-04 on a prospective basis. The new standard was issued in May 2021 to clarify issuer accounting for modifications or exchanges of freestanding equity-classified written call options that remain equity classified after modification or exchange. The ASU requires an issuer to determine the accounting for the modification or exchange based on the economic substance of the modification or exchange. The adoption of this ASU did not have a material impact on our consolidated financial statements. Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity Effective January 1, 2022, we adopted ASU 2020-06 on a modified retrospective basis. The new standard was issued in August 2020 to simplify accounting for certain financial instruments. The ASU eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The ASU also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity’s own equity. The ASU amends the diluted earnings per share guidance, including the requirement to use if-converted method for all convertible instruments and an update for instruments that can be settled in either cash or shares. The adoption of this ASU did not have a material impact on our consolidated financial statements.

For the nine months ended September 30, 2022 and 2021, Other revenue includes a $483 million mark-to-market loss and a $36 million mark-to-market gain, respectively. 2 Includes revenues from lease contracts for the three months ended September 30, 2022 and 2021 of $128 million and $140 million, respectively, and for the nine months ended September 30, 2022 and 2021 of $435 million and $442 million, respectively. We disaggregate revenues into categories which represent our principal performance obligations within each business segment. These revenue categories represent the most significant revenue streams in each segment and consequently are considered to be the most relevant revenue information for management to consider in evaluating performance. Contract Balances Contract Receivables Contract Assets Contract Liabilities (millions of Canadian dollars) Balance as at September 30, 2022 2,307 233 2,201 Balance as at December 31, 2021 2,369 213 1,898 Contract receivables represent the amount of receivables derived from contracts with customers. Contract assets represent the amount of revenues which have been recognized in advance of payments received for performance obligations we have fulfilled (or partially fulfilled) and prior to the point in time at which our right to payment is unconditional. Amounts included in contract assets are transferred to accounts receivable when our right to receive the consideration becomes unconditional. Contract liabilities represent payments received for performance obligations which have not been fulfilled. Contract liabilities primarily relate to make-up rights and deferred revenues. Revenue recognized during the three and nine months ended September 30, 2022 included in contract liabilities at the beginning of the period is $57 million and $139 million, respectively. Increases in contract liabilities from cash received, net of amounts recognized as revenues, during the three and nine months ended September 30, 2022 were $138 million and $366 million, respectively. Performance Obligations There were no material revenues recognized in the three and nine months ended September 30, 2022 from performance obligations satisfied in previous periods. Revenues to be Recognized from Unfulfilled Performance Obligations Total revenues from performance obligations expected to be fulfilled in future periods are $59.3 billion, of which $1.9 billion and $6.4 billion are expected to be recognized during the remaining three months ending December 31, 2022 and the year ending December 31, 2023, respectively. The revenues excluded from the amounts above based on optional exemptions available under Accounting Standards Codification (ASC) 606, as explained below, represent a significant portion of our overall revenues and revenues from contracts with customers. Certain revenues such as flow-through operating costs charged to shippers are recognized at the amount for which we have the right to invoice our customers and are excluded from the amounts for revenues to be recognized in the future from unfulfilled performance obligations above. Variable consideration is excluded from the amounts above due to the uncertainty of the associated consideration, which is generally resolved when actual volumes and prices are determined. For example, we consider interruptible transportation service revenues to be variable revenues since volumes cannot be estimated. Additionally, the effect of escalation on certain tolls which are contractually escalated for inflation has not been reflected in the amounts above as it is not possible to reliably estimate future inflation rates. Revenues for periods extending beyond the current rate settlement term for regulated contracts where the tolls are periodically reset by the regulator are excluded from the amounts above since future tolls remain unknown. Finally, revenues from contracts with customers which have an original expected duration of one year or less are excluded from the amounts above. Variable Consideration During the three and nine months ended September 30, 2022, revenue for the Canadian Mainline has been recognized in accordance with the terms of the Competitive Tolling Settlement, which expired on June 30, 2021. The tolls in place on June 30, 2021 continue on an interim basis until a new commercial arrangement is implemented and are subject to finalization and adjustment applicable to the interim period, if any. Due to the uncertainty of adjustment to tolling pursuant to a Canada Energy Regulator (CER) decision and potential customer negotiations, interim toll revenue recognized during the three and nine months ended September 30, 2022 is considered variable consideration.

Earnings Per Share [Abstract]
EARNINGS PER COMMON SHARE AND DIVIDENDS PER SHARE	EARNINGS PER COMMON SHARE AND DIVIDENDS PER SHARE BASIC Earnings per common share is calculated by dividing earnings attributable to common shareholders by the weighted average number of common shares outstanding. On December 30, 2021, we closed the sale of our minority ownership in Noverco Inc. (Noverco). For both the three and nine months ended September 30, 2021, the weighted average number of common shares outstanding was reduced by our pro-rata weighted average interest in our own common shares of approximately 2 million, resulting from our reciprocal investment in Noverco. DILUTED The treasury stock method is used to determine the dilutive impact of stock options and restricted stock units (RSU). This method assumes any proceeds from the exercise of stock options and vesting of RSUs would be used to purchase common shares at the average market price during the period. Weighted average shares outstanding used to calculate basic and diluted earnings per share are as follows: Three months ended Nine months ended 2022 2021 2022 2021 (number of shares in millions) Weighted average shares outstanding 2,025 2,024 2,026 2,023 Effect of dilutive options and RSUs 3 2 3 2 Diluted weighted average shares outstanding 2,028 2,026 2,029 2,025 For the three months ended September 30, 2022 and 2021, 11.4 million and 13.3 million, respectively, of anti-dilutive stock options with a weighted average exercise price of $56.49 and $56.16, respectively, were excluded from the diluted earnings per common share calculation. For the nine months ended September 30, 2022 and 2021, 9.2 million and 20.5 million, respectively, of anti-dilutive stock options with a weighted average exercise price of $56.63 and $52.19, respectively, were excluded from the diluted earnings per common share calculation. DIVIDENDS PER SHARE On November 2, 2022, our Board of Directors declared the following quarterly dividends. All dividends are payable on December 1, 2022 to shareholders of record on November 15, 2022. Dividend per share Common Shares 1 $0.86000 Preference Shares, Series A $0.34375 Preference Shares, Series B 2 $0.32513 Preference Shares, Series D $0.27875 Preference Shares, Series F $0.29306 Preference Shares, Series H $0.27350 Preference Shares, Series L 3 US$0.36612 Preference Shares, Series N $0.31788 Preference Shares, Series P $0.27369 Preference Shares, Series R $0.25456 Preference Shares, Series 1 US$0.37182 Preference Shares, Series 3 $0.23356 Preference Shares, Series 5 US$0.33596 Preference Shares, Series 7 $0.27806 Preference Shares, Series 9 $0.25606 Preference Shares, Series 11 $0.24613 Preference Shares, Series 13 $0.19019 Preference Shares, Series 15 $0.18644 Preference Shares, Series 19 $0.30625 1 The quarterly dividend per common share was increased 3% to $0.86 from $0.835, effective March 1, 2022. 2 The quarterly dividend per share paid on Preference Shares, Series B was increased to $0.32513 from $0.21340 on June 1, 2022 due to reset of the annual dividend on June 1, 2022. On June 1, 2022, all outstanding Preference Shares, Series C were converted to Preference Shares, Series B. 3 The quarterly dividend per share paid on Preference Shares, Series L was increased to US$0.36612 from US$0.30993 on September 1, 2022 due to reset of the annual dividend on September 1, 2022. PREFERENCE SHARE REDEMPTIONS On March 1, 2022, we redeemed our $750 million outstanding Cumulative Redeemable Minimum Rate Reset Preference Shares, Series 17. On June 1, 2022, we also redeemed our US$200 million outstanding Cumulative Redeemable Preference Shares, Series J. Dividends are cumulative, payable quarterly and are included in Preference share dividends in the Consolidated Statements of Earnings.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS AND DISPOSITIONS	ACQUISITIONS AND DISPOSITIONS DCP MIDSTREAM, LLC On August 17, 2022, we completed a joint venture merger transaction with Phillips 66 (P66) resulting in a single joint venture, DCP Midstream, LLC, holding both our and P66's indirect ownership interests in Gray Oak Pipeline, LLC (Gray Oak) and DCP Midstream, LP (DCP). Our ownership in DCP Midstream, LLC consists of Class A and Class B Interests which track to our investments in DCP, included in the Gas Transmission and Midstream segment, and Gray Oak, included in the Liquids Pipelines segment, respectively. Through our investment in DCP Midstream, LLC, we increased our indirect economic interest in Gray Oak to 58.5% from 22.8% and reduced our indirect economic interest in DCP to 13.2% from 28.3%. As a result of the transaction, Enbridge will assume operatorship of Gray Oak in the second quarter of 2023. We determined the fair value of our decrease in economic interest in DCP based on the unadjusted quoted market price of DCP’s publicly traded common units on the transaction closing date. The fair value of our increased economic interest in Gray Oak was determined using the fair value prescribed to the change in our economic interest in DCP. As a result of the merger transaction and the realignment of our economic interests in DCP and Gray Oak, we also received cash consideration of approximately $522 million (US$404 million) and recorded an accounting gain of $1.1 billion (US$832 million) to Gain on joint venture merger transaction in the Consolidated Statements of Earnings. Both DCP and Gray Oak continue to be accounted for as equity method investments. TRI GLOBAL ENERGY, LLC On September 27, 2022, through a wholly-owned United States (US) subsidiary, we acquired all of the outstanding common units in Tri Global Energy, LLC (TGE) for cash consideration of $295 million (US$215 million) plus potential contingent payments of up to $72 million (US$53 million) dependent on the achievement of performance milestones by TGE (the Acquisition). The Acquisition is subject to customary closing and working capital adjustments. TGE is an onshore renewable project developer in the US with a development portfolio of wind and solar projects. The Acquisition enhances Enbridge's renewable power platform and accelerates our North American growth strategy. We accounted for the Acquisition using the acquisition method as prescribed by ASC 805 Business Combinations . In accordance with valuation methodologies described in ASC 820 Fair Value Measurements , the acquired assets and assumed liabilities are recorded at their estimated fair values as at the date of acquisition. The following table summarizes the estimated preliminary fair values that were assigned to the net assets of TGE: September 27, 2022 (millions of Canadian dollars) Fair value of net assets acquired: Current assets 5 Property, plant and equipment 3 Long-term investments 8 Intangible assets (a) 117 Long-term assets 3 Current liabilities 61 Long-term liabilities (b) 123 Goodwill (c) 392 Purchase price: Cash 295 Contingent consideration (d) 49 344 a) Intangible assets consist of compensation expected to be earned by TGE on existing development contracts once certain project development milestones are met. Fair value was determined using a discounted cash flow method which is an income-based approach to valuation that estimates the present value of future projected benefits from the contracts. The intangible assets will be amortized on a straight-line basis over an expected useful life of two and a half years. b) Long-term liabilities consist primarily of obligations payable to third parties which are contingent on milestones being met for certain projects. Fair value represents the present value of the future cash flow payments at the date of the Acquisition. c) Goodwill is primarily attributable to expected future returns from new opportunities to develop wind and solar projects, as well as enhanced scale and operational diversity of our renewable projects portfolio. The goodwill balance recognized has been assigned to our Renewable Power Generation segment and is tax deductible over 15 years. d) We agreed to pay additional contingent consideration of up to US$53 million to TGE's former common unit holders if performance milestones are met on certain projects. The US$36 million of contingent consideration recognized in the purchase price represents the fair value of contingent consideration at the date of acquisition. The fair value was determined using an income-based approach. Upon completion of the Acquisition, we began consolidating TGE. For the period beginning September 27, 2022 through to September 30, 2022, operating revenues and earnings attributable to common shareholders generated by TGE were immaterial. The impact to our supplemental pro forma consolidated operating revenues and earnings attributable to common shareholders for the three and nine months ended September 30, 2022 and 2021, as if the Acquisition had been completed on January 1, 2021, was also immaterial. ATHABASCA REGIONAL OIL SANDS SYSTEM On September 28, 2022, we entered into an agreement to sell an 11.6% non-operating interest in seven pipelines in the Athabasca region of northern Alberta from our Regi onal Oil Sands System to Athabasca Indigenous Investments Limited Partnership, an entity representing 23 First Nation and Métis communities . We will maintain an 88.4% controlling interest in these assets, which are a component of our Liquids Pipelines segment, and continue to manage, operate and provide administrative services to them. On October 5, 2022, we closed the sale for total consideration of approximately $1.1 billion, less customary closing adjustments.

The following summarizes the types of market risks to which we are exposed and the risk management instruments used to mitigate them. We use a combination of qualifying and non-qualifying derivative instruments to manage the risks noted below. Foreign Exchange Risk We generate certain revenues, incur expenses, and hold a number of investments and subsidiaries that are denominated in currencies other than Canadian dollars. As a result, our earnings, cash flows and OCI are exposed to fluctuations resulting from foreign exchange rate variability. We employ financial derivative instruments to hedge foreign currency denominated earnings exposure. A combination of qualifying cash flow, fair value and non-qualifying derivative instruments is used to hedge anticipated foreign currency denominated revenues and expenses, and to manage variability in cash flows. We hedge certain net investments in US dollar denominated investments and subsidiaries using US dollar denominated debt. Interest Rate Risk Our earnings and cash flows are exposed to short-term interest rate variability due to the regular repricing of our variable rate debt, primarily commercial paper. We monitor our debt portfolio mix of fixed and variable rate debt instruments to manage a consolidated portfolio of floating rate debt within the Board of Directors approved policy limit of a maximum of 30% of floating rate debt as a percentage of total debt outstanding. We primarily use qualifying derivative instruments to manage interest rate risk. Pay fixed-receive floating interest rate swaps may be used to hedge against the effect of future interest rate movements. We have implemented a hedging program to partially mitigate the impact of short-term interest rate volatility on interest expense via execution of floating-to-fixed interest rate swaps. These hedges have an average fixed rate of 2.5%. We are exposed to changes in the fair value of fixed rate debt that arise as a result of the changes in market interest rates. Pay floating-receive fixed interest rate swaps are used, when applicable, to hedge against future changes to the fair value of fixed rate debt which mitigates the impact of fluctuations in the fair value of fixed rate debt via execution of fixed-to-floating interest rate swaps. As at September 30, 2022, we did not have any pay floating-receive fixed interest rate swaps outstanding. Our earnings and cash flows are also exposed to variability in longer term interest rates ahead of anticipated fixed rate term debt issuances. Forward starting interest rate swaps are used to hedge against the effect of future interest rate movements. We have established a program including some of our subsidiaries to partially mitigate our exposure to long-term interest rate variability on forecasted term debt issuances via execution of floating-to-fixed interest rate swaps with an average swap rate of 2.1%. Commodity Price Risk Our earnings and cash flows are exposed to changes in commodity prices as a result of our ownership interests in certain assets and investments, as well as through the activities of our energy services subsidiaries. These commodities include natural gas, crude oil, power and natural gas liquids (NGL). We employ financial and physical derivative instruments to fix a portion of the variable price exposures that arise from physical transactions involving these commodities. We use primarily non-qualifying derivative instruments to manage commodity price risk. Equity Price Risk Equity price risk is the risk of earnings fluctuations due to changes in our share price. We have exposure to our own common share price through the issuance of various forms of stock-based compensation, which affect earnings through revaluation of the outstanding units every period. We use equity derivatives to manage the earnings volatility derived from one form of stock-based compensation, restricted share units. We use a combination of qualifying and non-qualifying derivative instruments to manage equity price risk. TOTAL DERIVATIVE INSTRUMENTS We generally have a policy of entering into individual International Swaps and Derivatives Association, Inc. (ISDA) agreements, or other similar derivative agreements, with the majority of our financial derivative counterparties. These agreements provide for the net settlement of derivative instruments outstanding with specific counterparties in the event of bankruptcy or other significant credit events, and reduce our credit risk exposure on financial derivative asset positions outstanding with the counterparties in those circumstances. The following table summarizes the Consolidated Statements of Financial Position location and carrying value of our derivative instruments, as well as the maximum potential settlement amounts in the event of the specific circumstances described above. All amounts are presented gross in the Consolidated Statements of Financial Position.

Fair Value Derivatives For foreign exchange derivative instruments that are designated and qualify as fair value hedges, the gain or loss on the derivative is included in Net foreign currency gain/(loss) or Interest expense in the Consolidated Statements of Earnings. The offsetting loss or gain on the hedged item attributable to the hedged risk is included in Net foreign currency gain/(loss) in the Consolidated Statements of Earnings. Any excluded components are included in the Consolidated Statements of Comprehensive Income. Three months ended Nine months ended 2022 2021 2022 2021 (millions of Canadian dollars) Unrealized gain on derivative 122 50 221 15 Unrealized loss on hedged item (122) (50) (211) (22) Realized loss on derivative (5) (1) (101) (40) Realized gain on hedged item — — 85 45 The Effect of Derivative Instruments on the Statements of Earnings and Comprehensive Income The following table presents the effect of cash flow hedges and fair value hedges on our consolidated earnings and consolidated comprehensive income, before the effect of income taxes: Three months ended Nine months ended 2022 2021 2022 2021 (millions of Canadian dollars) Amount of unrealized gain/(loss) recognized in OCI Cash flow hedges Foreign exchange contracts 1 4 3 (21) Interest rate contracts 230 (1) 1,087 293 Commodity contracts (16) (21) (27) (25) Other contracts (4) (2) (4) 2 Fair value hedges Foreign exchange contracts (33) (1) (38) (3) 178 (21) 1,021 246 Amount of (gain)/loss reclassified from AOCI to earnings Foreign exchange contracts 1 — 1 13 4 Interest rate contracts 2 45 76 187 218 Commodity contracts — (4) — (4) Other contracts 3 1 — 3 1 46 73 203 219 1 Reported within Transportation and other services revenues and Net foreign currency gain/(loss) in the Consolidated Statements of Earnings. 2 Reported within Interest expense in the Consolidated Statements of Earnings. 3 Reported within Operating and administrative expense in the Consolidated Statements of Earnings. We estimate that a gain of $57 million of AOCI related to unrealized cash flow hedges will be reclassified to earnings in the next 12 months. Actual amounts reclassified to earnings depend on the foreign exchange rates, interest rates and commodity prices in effect when derivative contracts that are currently outstanding mature. For all forecasted transactions, the maximum term over which we are hedging exposures to the variability of cash flows is 39 months as at September 30, 2022. Non-Qualifying Derivatives The following table presents the unrealized gains and losses associated with changes in the fair value of our non-qualifying derivatives: Three months ended Nine months ended 2022 2021 2022 2021 (millions of Canadian dollars) Foreign exchange contracts 1 (1,379) (436) (1,752) 18 Interest rate contracts 2 17 2 1 4 Commodity contracts 3 89 (102) 59 (120) Other contracts 4 (3) 2 1 12 Total unrealized derivative fair value loss, net (1,276) (534) (1,691) (86) 1 For the respective nine months ended periods, reported within Transportation and other services revenues (2022 - $375 million loss; 2021 - $71 million gain) and Net foreign currency gain/(loss) (2022 - $1,377 million loss; 2021 - $53 million loss) in the Consolidated Statements of Earnings. 2 Reported as an (increase)/decrease within Interest expense in the Consolidated Statements of Earnings. 3 For the respective nine months ended periods, reported within Transportation and other services revenues (2022 - $12 million gain; 2021 - nil), Commodity sales (2022 - $151 million gain; 2021 - $5 million loss), Commodity costs (2022 - $116 million loss; 2021 - $124 million loss) and Operating and administrative expense (2022 - $12 million gain; 2021 - $8 million gain) in the Consolidated Statements of Earnings. 4 Reported within Operating and administrative expense in the Consolidated Statements of Earnings. LIQUIDITY RISK Liquidity risk is the risk that we will not be able to meet our financial obligations, including commitments and guarantees, as they become due. In order to mitigate this risk, we forecast cash requirements over a 12-month rolling time period to determine whether sufficient funds will be available and maintain substantial capacity under our committed bank lines of credit to address any contingencies. Our primary sources of liquidity and capital resources are funds generated from operations, the issuance of commercial paper and draws under committed credit facilities and long-term debt, which includes debentures and medium-term notes. Our shelf prospectuses with securities regulators enable ready access to either the Canadian or US public capital markets, subject to market conditions. In addition, we maintain sufficient liquidity through committed credit facilities with a diversified group of banks and institutions which, if necessary, enables us to fund all anticipated requirements for approximately one year without accessing the capital markets. We are in compliance with all the terms and conditions of our committed credit facility agreements and term debt indentures as at September 30, 2022. As a result, all credit facilities are available to us and the banks are obligated to fund and have been funding us under the terms of the facilities. CREDIT RISK Entering into derivative instruments may result in exposure to credit risk from the possibility that a counterparty will default on its contractual obligations. In order to mitigate this risk, we enter into risk management transactions primarily with institutions that possess strong investment grade credit ratings. Credit risk relating to derivative counterparties is mitigated through maintenance and monitoring of credit exposure limits and contractual requirements, netting arrangements and ongoing monitoring of counterparty credit exposure using external credit rating services and other analytical tools. We have credit concentrations and credit exposure, with respect to derivative instruments, in the following counterparty segments: September 30, December 31, (millions of Canadian dollars) Canadian financial institutions 637 424 US financial institutions 361 130 European financial institutions 441 181 Asian financial institutions 208 30 Other 1 165 122 1,812 887 1 Other is comprised of commodity clearing house and physical natural gas and crude oil counterparties. As at September 30, 2022, we did not provide any letters of credit in lieu of providing cash collateral to our counterparties pursuant to the terms of the relevant ISDA agreements. We held no cash collateral on derivative asset exposures as at September 30, 2022 and December 31, 2021. Gross derivative balances have been presented without the effects of collateral posted. Derivative assets are adjusted for non-performance risk of our counterparties using their credit default swap spread rates, and are reflected at fair value. For derivative liabilities, our non-performance risk is considered in the valuation. Credit risk also arises from trade and other long-term receivables, and is mitigated through credit exposure limits and contractual requirements, assessment of credit ratings and netting arrangements. Within Enbridge Gas Inc., credit risk is mitigated by the utility's large and diversified customer base and the ability to recover an estimate for expected credit losses through the ratemaking process. We actively monitor the financial strength of large industrial customers, and in select cases, have obtained additional security to minimize the risk of default on receivables. Generally, we utilize a loss allowance matrix which contemplates historical credit losses by age of receivables, adjusted for any forward-looking information and management expectations to measure lifetime expected credit losses of receivables. The maximum exposure to credit risk related to non-derivative financial assets is their carrying value. FAIR VALUE MEASUREMENTS Our financial assets and liabilities measured at fair value on a recurring basis include derivative and other financial instruments. We also disclose the fair value of other financial instruments not measured at fair value. The fair value of financial instruments reflects our best estimates of market value based on generally accepted valuation techniques or models and is supported by observable market prices and rates. When such values are not available, we use discounted cash flow analysis from applicable yield curves based on observable market inputs to estimate fair value. FAIR VALUE OF FINANCIAL INSTRUMENTS We categorize our financial instruments measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 Level 1 includes financial instruments measured at fair value based on unadjusted quoted prices for identical assets and liabilities in active markets that are accessible at the measurement date. An active market for a financial instrument is considered to be a market where transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Our Level 1 instruments consist primarily of exchange-traded derivatives used to mitigate the risk of crude oil price fluctuations, US and Canadian treasury bills, investments in exchange-traded equity funds held by our captive insurance subsidiaries, as well as restricted long-term investments in Canadian equity securities that are held in trust in accordance with the CER's regulatory requirements under the Land Matters Consultation Initiative (LMCI). Level 2 Level 2 includes financial instrument valuations determined using directly or indirectly observable inputs other than quoted prices included within Level 1. Financial instruments in this category are valued using models or other industry standard valuation techniques derived from observable market data. Such valuation techniques include inputs such as quoted forward prices, time value, volatility factors and broker quotes that can be observed or corroborated in the market for the entire duration of the financial instrument. Derivatives valued using Level 2 inputs include non-exchange traded derivatives such as over-the-counter foreign exchange forward and cross currency swap contracts, interest rate swaps, physical forward commodity contracts, as well as commodity swaps and options for which observable inputs can be obtained. We have also categorized the fair value of our long-term debt, investments in debt securities held by our captive insurance subsidiaries, and restricted long-term investments in Canadian government bonds held in trust in accordance with the CER's regulatory requirements under the LMCI as Level 2. The fair value of our available-for-sale preferred share investment is based on the redemption value, which equals the face value plus accrued and unpaid interest periodically reset based on market interest rates. The fair value of our long-term debt is based on quoted market prices for instruments of similar yield, credit risk and tenor. When possible, the fair value of our restricted long-term investments is based on quoted market prices for similar instruments and, if not available, based on broker quotes. Level 3 Level 3 includes derivative valuations based on inputs which are less observable, unavailable or where the observable data does not support a significant portion of the derivative’s fair value. Generally, Level 3 derivatives are longer dated transactions, occur in less active markets, occur at locations where pricing information is not available or have no binding broker quote to support Level 2 classification. We have developed methodologies, benchmarked against industry standards, to determine fair value for these derivatives based on extrapolation of observable future prices and rates. Derivatives valued using Level 3 inputs primarily include long-dated derivative power, NGL and natural gas contracts, basis swaps, commodity swaps, and power and energy swaps, as well as physical forward commodity contracts. We do not have any other financial instruments categorized in Level 3. We use the most observable inputs available to estimate the fair value of our derivatives. When possible, we estimate the fair value of our derivatives based on quoted market prices. If quoted market prices are not available, we use estimates from third party brokers. For non-exchange traded derivatives classified in Levels 2 and 3, we use standard valuation techniques to calculate the estimated fair value. These methods include discounted cash flows for forwards and swaps and Black-Scholes-Merton pricing models for options. Depending on the type of derivative and nature of the underlying risk, we use observable market prices (interest, foreign exchange, commodity and share price) and volatility as primary inputs to these valuation techniques. Finally, we consider our own credit default swap spread as well as the credit default swap spreads associated with our counterparties in our estimation of fair value. We have categorized our derivative assets and liabilities measured at fair value as follows: September 30, 2022 Level 1 Level 2 Level 3 Total Gross (millions of Canadian dollars) Financial assets Current derivative assets Foreign exchange contracts — 65 — 65 Interest rate contracts — 128 — 128 Commodity contracts 120 142 152 414 Other contracts — 6 — 6 120 341 152 613 Long-term derivative assets Foreign exchange contracts — 320 — 320 Interest rate contracts — 830 — 830 Commodity contracts — 24 42 66 Other contracts — 1 — 1 — 1,175 42 1,217 Financial liabilities Current derivative liabilities Foreign exchange contracts — (730) — (730) Interest rate contracts — (17) — (17) Commodity contracts (56) (188) (168) (412) Other contracts — — — — (56) (935) (168) (1,159) Long-term derivative liabilities Foreign exchange contracts — (1,429) — (1,429) Interest rate contracts — (3) — (3) Commodity contracts — (49) (123) (172) Other contracts — (1) — (1) — (1,482) (123) (1,605) Total net financial assets/(liabilities) Foreign exchange contracts — (1,774) — (1,774) Interest rate contracts — 938 — 938 Commodity contracts 64 (71) (97) (104) Other contracts — 6 — 6 64 (901) (97) (934) December 31, 2021 Level 1 Level 2 Level 3 Total Gross (millions of Canadian dollars) Financial assets Current derivative assets Foreign exchange contracts — 259 — 259 Interest rate contracts — 64 — 64 Commodity contracts 38 71 95 204 Other contracts — 2 — 2 38 396 95 529 Long-term derivative assets Foreign exchange contracts — 240 — 240 Interest rate contracts — 88 — 88 Commodity contracts — 21 8 29 Other contracts — 3 — 3 — 352 8 360 Financial liabilities Current derivative liabilities Foreign exchange contracts — (303) — (303) Interest rate contracts — (150) — (150) Commodity contracts (52) (66) (146) (264) (52) (519) (146) (717) Long-term derivative liabilities Foreign exchange contracts — (423) — (423) Interest rate contracts — (24) — (24) Commodity contracts — (19) (65) (84) — (466) (65) (531) Total net financial assets/(liabilities) Foreign exchange contracts — (227) — (227) Interest rate contracts — (22) — (22) Commodity contracts (14) 7 (108) (115) Other contracts — 5 — 5 (14) (237) (108) (359) The significant unobservable inputs used in the fair value measurement of Level 3 derivative instruments were as follows: September 30, 2022 Fair Unobservable Minimum Maximum Weighted Unit of (fair value in millions of Canadian dollars) Commodity contracts - financial 1 Natural gas 9 Forward gas price 5.41 12.51 7.75 $/mmbtu 2 Crude 5 Forward crude price 64.09 108.87 77.06 $/barrel Power (80) Forward power price 35.56 207.09 93.98 $/MW/H Commodity contracts - physical 1 Natural gas (66) Forward gas price 3.43 22.01 7.11 $/mmbtu 2 Crude 24 Forward crude price 72.52 125.74 90.39 $/barrel Power 11 Forward power price 37.08 175.52 81.95 $/MW/H (97) 1 Financial and physical forward commodity contracts are valued using a market approach valuation technique. 2 One million British thermal units (mmbtu). 3 If adjusted, the significant unobservable inputs disclosed in the table above would have a direct impact on the fair value of our Level 3 derivative instruments. The significant unobservable inputs used in the fair value measurement of Level 3 derivative instruments include forward commodity prices. Changes in forward commodity prices could result in significantly different fair values for our Level 3 derivatives. Changes in net fair value of derivative assets and liabilities classified as Level 3 in the fair value hierarchy were as follows: Nine months ended 2022 2021 (millions of Canadian dollars) Level 3 net derivative liability at beginning of period (108) (191) Total gain/(loss) Included in earnings 1 41 (181) Included in OCI (28) (29) Settlements (2) 167 Level 3 net derivative liability at end of period (97) (234) 1 Reported within Transportation and other services revenues, Commodity costs and Operating and administrative expense in the Consolidated Statements of Earnings. There were no transfers into or out of Level 3 as at September 30, 2022 or December 31, 2021. NET INVESTMENT HEDGES We currently have designated a portion of our US dollar denominated debt as a hedge of our net investment in US dollar denominated investments and subsidiaries. During the nine months ended September 30, 2022 and 2021, we recognized an unrealized foreign exchange loss of $1,191 million and gain of $18 million, respectively, on the translation of US dollar denominated debt. During the nine months ended September 30, 2022 and 2021, we recognized nil on the change in fair value of our outstanding foreign exchange forward contracts in OCI and nil in OCI associated with the settlement of foreign exchange forward contracts or with the settlement of US dollar denominated debt that had matured during the period. FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS Certain long-term investments in other entities with no actively quoted prices are classified as Fair Value Measurement Alternative (FVMA) investments and are recorded at cost less impairment. The carrying value of FVMA investments totaled $102 million and $52 million as at September 30, 2022 and December 31, 2021, respectively. We have wholly-owned captive insurance subsidiaries whose principal activity is providing insurance and reinsurance coverage for certain insurable property and casualty risk exposures in the US and Canada of our operating subsidiaries and certain equity investments. As at September 30, 2022, the fair value of short- and long-term investment s in equity funds and debt securities held by our captive insurance subsidiaries was $108 million and $400 million, respectively (December 31, 2021 - $14 million and $290 million, respectively). These investments in equity funds and debt securities are recognized at fair value, classified as Level 1 and Level 2 in the fair value hierarchy, respectively, and are recorded in Accounts receivable and other and Long-ter m investments, respectively, in the Consolidated Statements of Financial Position. There were unrealized holding losses in equity funds and debt securities of $13 million and $40 million for the three and nine months ended September 30, 2022, respectively (2021 - gains of $1 million and $4 million, respectively).

INCOME TAXES

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The effective income tax rates for the three months ended September 30, 2022 and 2021 were 18.7% and 19.6%, respectively, and for the nine months ended September 30, 2022 and 2021 were 20.5% and 18.0%, respectively. The period-over-period changes in the effective income tax rates are due to the effect of rate-regulated accounting for income taxes and other permanent differences relative to earnings, an increase in US minimum tax, offset by a statutory rate decrease in Pennsylvania and an adjustment to 2020 regulatory balances in the three-month period of the prior year.

CONTINGENCIES	CONTINGENCIES We and our subsidiaries are involved in various legal and regulatory actions and proceedings which arise in the normal course of business, including interventions in regulatory proceedings and challenges to regulatory approvals and permits. While the final outcome of such actions and proceedings cannot be predicted with certainty, management believes that the resolution of such actions and proceedings will not have a material impact on our interim consolidated financial position or results of operations. TAX MATTERS We and our subsidiaries maintain tax liabilities related to uncertain tax positions. While fully supportable in our view, these tax positions, if challenged by tax authorities, may not be fully sustained on review.

CHANGES IN ACCOUNTING POLICIES

CHANGES IN ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2022
Accounting Standards Update and Change in Accounting Principle [Abstract]
ADOPTION OF NEW ACCOUNTING STANDARDS	ADOPTION OF NEW ACCOUNTING STANDARDS Disclosures About Government Assistance Effective January 1, 2022, we adopted Accounting Standards Update (ASU) 2021-10 on a prospective basis. The new standard was issued in November 2021 to increase the transparency of government assistance to business entities. The ASU adds new disclosure requirements for transactions with governments that are accounted for using a grant or contribution accounting model by analogy. The required disclosures include information about the nature of transactions, accounting policy applied, impacted financial statement line items and significant terms and conditions. The adoption of this ASU did not have a material impact on our consolidated financial statements. Accounting for Certain Lessor Leases with Variable Lease Payments Effective January 1, 2022, we adopted ASU 2021-05 on a prospective basis. The new standard was issued in July 2021 to amend lessor accounting for certain leases with variable lease payments that do not depend on a reference index or a rate and would have resulted in the recognition of a loss at lease commencement if classified as a sales-type or a direct financing lease. The ASU amends the classification requirements of such leases for lessors to result in an operating lease classification. The adoption of this ASU did not have a material impact on our consolidated financial statements. Accounting for Modifications or Exchanges of Certain Equity-Classified Contracts Effective January 1, 2022, we adopted ASU 2021-04 on a prospective basis. The new standard was issued in May 2021 to clarify issuer accounting for modifications or exchanges of freestanding equity-classified written call options that remain equity classified after modification or exchange. The ASU requires an issuer to determine the accounting for the modification or exchange based on the economic substance of the modification or exchange. The adoption of this ASU did not have a material impact on our consolidated financial statements. Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity Effective January 1, 2022, we adopted ASU 2020-06 on a modified retrospective basis. The new standard was issued in August 2020 to simplify accounting for certain financial instruments. The ASU eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The ASU also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity’s own equity. The ASU amends the diluted earnings per share guidance, including the requirement to use if-converted method for all convertible instruments and an update for instruments that can be settled in either cash or shares. The adoption of this ASU did not have a material impact on our consolidated financial statements.

Schedule of Recognized Identified Assets Acquired and Liabilities Assumed	The following table summarizes the estimated preliminary fair values that were assigned to the net assets of TGE: September 27, 2022 (millions of Canadian dollars) Fair value of net assets acquired: Current assets 5 Property, plant and equipment 3 Long-term investments 8 Intangible assets (a) 117 Long-term assets 3 Current liabilities 61 Long-term liabilities (b) 123 Goodwill (c) 392 Purchase price: Cash 295 Contingent consideration (d) 49 344 a) Intangible assets consist of compensation expected to be earned by TGE on existing development contracts once certain project development milestones are met. Fair value was determined using a discounted cash flow method which is an income-based approach to valuation that estimates the present value of future projected benefits from the contracts. The intangible assets will be amortized on a straight-line basis over an expected useful life of two and a half years. b) Long-term liabilities consist primarily of obligations payable to third parties which are contingent on milestones being met for certain projects. Fair value represents the present value of the future cash flow payments at the date of the Acquisition. c) Goodwill is primarily attributable to expected future returns from new opportunities to develop wind and solar projects, as well as enhanced scale and operational diversity of our renewable projects portfolio. The goodwill balance recognized has been assigned to our Renewable Power Generation segment and is tax deductible over 15 years. d) We agreed to pay additional contingent consideration of up to US$53 million to TGE's former common unit holders if performance milestones are met on certain projects. The US$36 million of contingent consideration recognized in the purchase price represents the fair value of contingent consideration at the date of acquisition. The fair value was determined using an income-based approach.
