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, 2022. 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, 2022. 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.

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 June 30, 2023 2,182 229 2,283 Balance as at December 31, 2022 3,183 230 2,241 Contract receivables represent the amount of receivables derived from contracts with customers. Contract assets represent the amount of revenues which has been recognized in advance of payments received for performance obligations we have fulfilled (or have 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 six months ended June 30, 2023 included in contract liabilities at the beginning of the period was $53 million and $89 million, respectively. Increases in contract liabilities from cash received, net of amounts recognized as revenues, during the three and six months ended June 30, 2023 were $43 million and $167 million, respectively. Performance Obligations There were no material revenues recognized in the three and six months ended June 30, 2023 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 is $57.9 billion, of which $3.9 billion and $6.7 billion are expected to be recognized during the remaining six months ending December 31, 2023 and the year ending December 31, 2024, respectively. The revenues excluded from the amounts above based on optional exemptions available under Accounting Standards Codification 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 six months ended June 30, 2023, revenue for the Canadian Mainline has been recognized in accordance with the terms of the Competitive Tolling Settlement (CTS), which expired on June 30, 2021. The tolls in place on June 30, 2021 continued on an interim basis until July 1, 2023 when new interim tolls took effect. Until a new commercial arrangement is approved, the tolls 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 six months ended June 30, 2023 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. DILUTED The treasury stock method is used to determine the dilutive impact of stock options and RSUs. 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 Six months ended 2023 2022 2023 2022 (number of shares in millions) Weighted average shares outstanding 2,024 2,026 2,025 2,026 Effect of dilutive options and RSUs 3 4 3 4 Diluted weighted average shares outstanding 2,027 2,030 2,028 2,030 For the three months ended June 30, 2023 and 2022, 16.3 million and 3.2 million, respectively, of anti-dilutive stock options with a weighted average exercise price of $55.46 and $59.29, respectively, were excluded from the diluted earnings per common share calculation. For the six months ended June 30, 2023 and 2022, 16.5 million and 8.0 million, respectively, of anti-dilutive stock options with a weighted average exercise price of $55.54 and $56.72, respectively, were excluded from the diluted earnings per common share calculation. DIVIDENDS PER SHARE On July 31, 2023, our Board of Directors declared the following quarterly dividends. All dividends are payable on September 1, 2023 to shareholders of record on August 15, 2023.

RISK MANAGEMENT AND FINANCIAL I

RISK MANAGEMENT AND FINANCIAL INSTRUMENTS	6 Months Ended
	Jun. 30, 2023
Derivative Instruments and Hedging Activities Disclosure [Abstract]
RISK MANAGEMENT AND FINANCIAL INSTRUMENTS	RISK MANAGEMENT AND FINANCIAL INSTRUMENTS MARKET RISK Our earnings, cash flows and other comprehensive income/(loss) (OCI) are subject to movements in foreign exchange rates, interest rates, commodity prices and our share price (collectively, market risks). Formal risk management policies, processes and systems have been designed to mitigate these risks. 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 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 United States (US) dollar-denominated investments and subsidiaries using foreign currency derivatives and US dollar-denominated debt. The foreign exchange risks inherent within the CTS framework are not present in the negotiated settlement. Accordingly, our foreign exchange hedging program related to the Canadian Mainline will no longer be required, and the related derivatives were terminated in the first quarter of 2023 for a realized loss of $638 million. 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 the execution of floating-to-fixed interest rate swaps. These hedges have an average fixed rate of 4.1% . On March 8, 2023, we issued US$700 million three-year fixed rate notes, which include the right for us to call at par after the first year. A corresponding fix-to-floating cancellable swap was also executed which gives the swap counterparty a similar right to cancel the swap after the first year. This swap has a fixed rate of 6.0%. This instrument was our only pay floating-receive fixed interest rate swap outstanding as at June 30, 2023. 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 forecas ted term debt issuances via the execution of floating-to-fixed interest rate swaps with an average swap rate of 2.6%. 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 the revaluation of outstanding units every period. We use equity derivatives to manage the earnings volatility derived from one form of stock-based compensation, RSUs. 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.

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 Other income/(expense) 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 Other income/(expense) in the Consolidated Statements of Earnings. Any excluded components are included in the Consolidated Statements of Comprehensive Income.

We estimate that a gain of $16 million from AOCI related to 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 30 months as at June 30, 2023. 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 Six months ended 2023 2022 2023 2022 (millions of Canadian dollars) Foreign exchange contracts 1 509 (806) 1,065 (373) Interest rate contracts 2 45 (16) 55 (16) Commodity contracts 3 62 38 23 (30) Other contracts 4 (1) — (8) 4 Total unrealized derivative fair value gain/(loss), net 615 (784) 1,135 (415) 1 For the respective six months ended periods, reported within Transportation and other services revenues (2023 - $645 million gain; 2022 - $65 million loss) and Other income/(expense) (2023 - $420 million gain; 2022 - $308 million loss) in the Consolidated Statements of Earnings. 2 Reported as an increase within Interest expense in the Consolidated Statements of Earnings. 3 For the respective six months ended periods, reported within Transportation and other services revenues (2023 - $8 million gain; 2022 - $25 million gain), Commodity sales (2023 - $96 million gain; 2022 - $109 million gain), Commodity costs (2023 - $51 million loss; 2022 - $167 million loss) and Operating and administrative expense (2023 - $30 million loss; 2022 - $3 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 were in compliance with all the terms and conditions of our committed credit facility agreements and term debt indentures as at June 30, 2023. As a result, all credit facilities are available to us and the banks are obligated to fund 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 the 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: June 30, December 31, (millions of Canadian dollars) Canadian financial institutions 499 644 US financial institutions 136 277 European financial institutions 214 334 Asian financial institutions 109 224 Other 1 89 105 1,047 1,584 1 Other is comprised of commodity clearing house and physical natural gas and crude oil counterparties. As at June 30, 2023, 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 June 30, 2023 and December 31, 2022. 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, the assessment of credit ratings and netting arrangements. Within Enbridge Gas, 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 derivatives 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 accordance with the CER's regulatory requirements under the LMCI as Level 2. 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 derivatives' 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 the 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: June 30, 2023 Level 1 Level 2 Level 3 Total Gross (millions of Canadian dollars) Financial assets Current derivative assets Foreign exchange contracts — 129 — 129 Interest rate contracts — 263 — 263 Commodity contracts 43 47 149 239 Other contracts — 1 — 1 43 440 149 632 Long-term derivative assets Foreign exchange contracts — 178 — 178 Interest rate contracts — 213 — 213 Commodity contracts — 17 51 68 — 408 51 459 Financial liabilities Current derivative liabilities Foreign exchange contracts — (86) — (86) Interest rate contracts — (2) — (2) Commodity contracts (21) (39) (200) (260) (21) (127) (200) (348) Long-term derivative liabilities Foreign exchange contracts — (616) — (616) Interest rate contracts — (9) — (9) Commodity contracts — (26) (87) (113) — (651) (87) (738) Total net financial asset/(liability) Foreign exchange contracts — (395) — (395) Interest rate contracts — 465 — 465 Commodity contracts 22 (1) (87) (66) Other contracts — 1 — 1 22 70 (87) 5 December 31, 2022 Level 1 Level 2 Level 3 Total Gross (millions of Canadian dollars) Financial assets Current derivative assets Foreign exchange contracts — 46 — 46 Interest rate contracts — 660 — 660 Commodity contracts 65 90 147 302 Other contracts — 7 — 7 65 803 147 1,015 Long-term derivative assets Foreign exchange contracts — 309 — 309 Interest rate contracts — 254 — 254 Commodity contracts — 17 44 61 Other contracts — 3 — 3 — 583 44 627 Financial liabilities Current derivative liabilities Foreign exchange contracts — (566) — (566) Commodity contracts (60) (77) (195) (332) (60) (643) (195) (898) Long-term derivative liabilities Foreign exchange contracts — (1,116) — (1,116) Interest rate contracts — (4) — (4) Commodity contracts — (38) (132) (170) — (1,158) (132) (1,290) Total net financial asset/(liability) Foreign exchange contracts — (1,327) — (1,327) Interest rate contracts — 910 — 910 Commodity contracts 5 (8) (136) (139) Other contracts — 10 — 10 5 (415) (136) (546) The significant unobservable inputs used in the fair value measurement of Level 3 derivative instruments were as follows: June 30, 2023 Fair Unobservable Minimum Maximum Weighted Unit of (fair value in millions of Canadian dollars) Commodity contracts - financial 1 Natural gas (16) Forward gas price 1.59 8.82 4.48 $/mmbtu 2 Crude (8) Forward crude price 70.23 90.70 81.07 $/barrel Power (91) Forward power price 25.85 255.75 63.34 $/MW/H Commodity contracts - physical 1 Natural gas (12) Forward gas price 1.66 23.07 4.65 $/mmbtu 2 Crude (3) Forward crude price 73.18 116.60 86.60 $/barrel Power 43 Forward power price 24.26 96.39 55.05 $/MW/H (87) 1 Financial and physical forward commodity contracts are valued using a market approach valuation technique. 2 One million British thermal units (mmbtu). 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: Six months ended 2023 2022 (millions of Canadian dollars) Level 3 net derivative liability at beginning of period (136) (108) Total gain/(loss) Included in earnings 1 11 14 Included in OCI 35 (11) Settlements 3 (2) Level 3 net derivative liability at end of period (87) (107) 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 June 30, 2023 or December 31, 2022. 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 six months ended June 30, 2023 and 2022, we recognized unrealized foreign exchange gains of $444 million and losses of $257 million, respectively, on the translation of US dollar-denominated debt, in OCI. No unrealized gains or losses on the change in fair value of our outstanding foreign exchange forward contracts were recognized in OCI during the six months ended June 30, 2023 and 2022. No realized gains or losses associated with the settlement of foreign exchange forward contracts were recognized in OCI during the six months ended June 30, 2023 and 2022. During the six months ended June 30, 2023 and 2022, we recognized a realized loss of $44 million and nil, respectively, associated with the settlement of US dollar-denominated debt that had matured during the period, in OCI. 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 $207 million and $102 million as at June 30, 2023 and December 31, 2022, respectively. As at June 30, 2023, we had investments with a fair value of $664 million included in Restricted long-term investments in the Consolidated Statements of Financial Position (December 31, 2022 - $593 million). These securities are classified as available-for-sale and represent restricted funds which are collected from customers and held in trust for the purpose of funding pipeline abandonment in accordance with the CER's regulatory requirements. We had restricted long-term investments held in trust totaling $252 million as at June 30, 2023, which are classified as Level 1 in the fair value hierarchy (December 31, 2022 - $236 million). We also had restricted long-term investments held in trust totaling $412 million (cost basis - $463 million ) and $357 million (cost basis - $437 million ) as at June 30, 2023 and December 31, 2022, respectively, which are classified as Level 2 in the fair value hierarchy. There were unrealized holding gains of $3 million and $37 million on these investments for the three and six months ended June 30, 2023, respectively (2022 - losses of $71 million and $131 million, 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 of our operating subsidiaries and certain equity investments. As at June 30, 2023, the fair value of investments in equity funds and debt securities held by our captive insurance subsidiaries was $354 million and $323 million, respectively (December 31, 2022 - $335 million and $298 million, respectively). Our investments in debt securities had a cost basis of $314 million as at June 30, 2023 (December 31, 2022 - $295 million). 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 Other current assets and Long-term investments in the Consolidated Statements of Financial Position. There were unrealized holding gains of $7 million and $22 million for the three and six months ended June 30, 2023, respectively (2022 - losses of $19 million and $27 million, respectively).

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The effective income tax rates for the three months ended June 30, 2023 and 2022 were 20.6% and 18.0%, respectively, and for the six months ended June 30, 2023 and 2022 were 21.0% and 21.4%, respectively. The period-over-period changes in the effective income tax rates are due to the effects of rate-regulated accounting for income taxes, higher investment tax credits available on certain capital projects in the US and an increase in earnings attributable to non-controlling interests, relative to higher earnings in the 2023 periods.

Loss Contingency [Abstract]
CONTINGENCIES	CONTINGENCIES LITIGATION We and our subsidiaries are subject to 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. INSURANCE We maintain an insurance program for us, our subsidiaries and certain of our affiliates to mitigate a certain portion of our risks. However, not all potential risks arising from our operations are insurable, or are insured by us as a result of availability, high premiums and for various other reasons. We self-insure a significant portion of certain risks through our wholly-owned captive insurance subsidiaries, and our insurance coverage is subject to terms and conditions, exclusions and large deductibles or self-insured retentions which may reduce or eliminate coverage in certain circumstances. Our insurance policies are generally renewed on an annual basis and, depending on factors such as market conditions, the premiums, terms, policy limits and/or deductibles, can vary substantially. We can give no assurance that we will be able to maintain adequate insurance in the future at rates or on other terms we consider commercially reasonable. In such case, we may decide to self-insure additional risks. In the unlikely event multiple insurable incidents occur which exceed coverage limits within the same insurance period, the total insurance coverage will be allocated among entities on an equitable basis based on an insurance allocation agreement we have entered into with us and other subsidiaries. Insurance estimates include certain assumptions and management judgments regarding the frequency and severity of claims, claim development and settlement practices and the selection of estimated loss among estimates derived using different methods.
