| 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 (U.S. GAAP) and Regulation S-X for interim consolidated financial information. They do not include all of the information and notes required by U.S. 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, 2019 . 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, 2019 , 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 the supply of and demand for crude oil and natural gas, and may not be indicative of annual results. |
CHANGES IN ACCOUNTING POLICIES
| CHANGES IN ACCOUNTING POLICIES | 6 Months Ended |
| Jun. 30, 2020 | |
| Accounting Standards Update and Change in Accounting Principle [Abstract] | |
| CHANGES IN ACCOUNTING POLICIES | CHANGES IN ACCOUNTING POLICIES ADOPTION OF NEW ACCOUNTING STANDARDS Clarifying Interaction between Collaborative Arrangements and Revenue from Contracts with Customers Effective January 1, 2020, we adopted Accounting Standards Update (ASU) 2018-18 on a retrospective basis. The new standard was issued in November 2018 to provide clarity on when transactions between entities in a collaborative arrangement should be accounted for under the new revenue standard, Accounting Standards Codification (ASC) 606. In determining whether transactions in collaborative arrangements should be accounted for under the revenue standard, the update specifies that entities shall apply unit of account guidance to identify distinct goods or services and whether such goods and services are separately identifiable from other promises in the contract. ASU 2018-18 also precludes entities from presenting transactions with a collaborative partner which are not in scope of the new revenue standard together with revenue from contracts with customers. The adoption of this ASU did not have a material impact on our consolidated financial statements. Disclosure Effectiveness Effective January 1, 2020, we adopted ASU 2018-13 on both a retrospective and prospective basis depending on the change. The new standard was issued to improve the disclosure requirements for fair value measurements by eliminating and modifying some disclosures, while also adding new disclosures. The adoption of this ASU did not have a material impact on our consolidated financial statements. Accounting for Credit Losses Effective January 1, 2020, we adopted ASU 2016-13 on a modified retrospective basis. The new standard was issued in June 2016 with the intent of providing financial statement users with more useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The previous accounting treatment used the incurred loss methodology for recognizing credit losses that delayed the recognition until it was probable a loss had been incurred. The accounting update adds a new impairment model, known as the current expected credit loss model, which is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the Financial Accounting Standards Board believes results in more timely recognition of such losses. Further, ASU 2018-19 was issued in November 2018 to clarify that operating lease receivables should be accounted for under the new leases standard, ASC 842, and are not within the scope of ASC 326, Financial Instruments - Credit Losses. For accounts receivable, a loss allowance matrix is utilized to measure lifetime expected credit losses. The matrix contemplates historical credit losses by age of receivables, adjusted for any forward-looking information and management expectations. Other loan receivables and off-balance sheet commitments in scope of the new standard utilize a discounted cash flow methodology which calculates the current expected credit losses based on historical default probability rates associated with the credit rating of the counterparty and the related term of the loan or commitment, adjusted for forward-looking information and management expectations. On January 1, 2020 we recorded $66 million of additional Deficit on our Statements of Financial Position in connection with the adoption of ASU 2016-13. The adoption of this ASU did not have a material impact on the Consolidated Statements of Earnings, Comprehensive Income or Cash Flows during the period. FUTURE ACCOUNTING POLICY CHANGES Reference Rate Reform ASU 2020-04 was issued in March 2020 to provide temporary optional guidance in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles when accounting for contract modifications, hedging relationships and other transactions impacted by rate reform, subject to meeting certain criteria. ASU 2020-04 is effective as of March 12, 2020 through December 31, 2022. We had no transactions to which the ASU was applied since adoption and we are considering the impact of reference rate reform on our consolidated financial statements. Clarifying Interaction between Equity Securities, Equity Method Investments and Derivatives ASU 2020-01 was issued in January 2020 and clarifies that observable transactions should be considered for the purpose of applying the measurement alternative in accordance with ASC 321 immediately before the application or upon discontinuance of the equity method of accounting. Furthermore, the ASU clarifies that forward contracts or purchased options on equity securities are not out of scope of ASC 815 guidance only because, upon the contracts’ exercise, the equity securities could be accounted for under the equity method of accounting or fair value option. ASU 2020-01 is effective January 1, 2021 with early adoption permitted and is applied prospectively. The adoption of ASU 2020-01 is not expected to have a material impact on our consolidated financial statements. Accounting for Income Taxes ASU 2019-12 was issued in December 2019 with the intent of simplifying the accounting for income taxes. The accounting update removes certain exceptions to the general principles in ASC 740 as well as provides simplification by clarifying and amending existing guidance. ASU 2019-12 is effective January 1, 2021 and entities are permitted to adopt the standard early. We are currently assessing the impact of the new standard on our consolidated financial statements. Disclosure Effectiveness ASU 2018-14 was issued in August 2018 to improve disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The amendment modifies the current guidance by adding and removing several disclosure requirements while also clarifying the guidance on current disclosure requirements. ASU 2018-14 is effective January 1, 2021 and entities are permitted to adopt the standard early. The adoption of ASU 2018-14 is not expected to have a material impact on our consolidated financial statements. |

We disaggregate revenues into categories which represent our principal performance obligations within each business segment because these revenues 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 Receivables Contract Assets Contract Liabilities (millions of Canadian dollars) Balance as at December 31, 2019 2,099 216 1,424 Balance as at June 30, 2020 1,642 228 1,540 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 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, 2020 included in contract liabilities at the beginning of the period was $21 million and $107 million , respectively. Increases in contract liabilities from cash received, net of amounts recognized as revenues during the three and six months ended June 30, 2020 were $104 million and $180 million , respectively. Performance Obligations There were no material revenues recognized in the three and six months ended June 30, 2020 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 $63.7 billion , of which $3.5 billion and $6.1 billion is expected to be recognized during the six months ending December 31, 2020 , and the year ending December 31, 2021 , respectively. The revenues excluded from the amounts above based on optional exemptions available under ASC 606, as explained below, represent a significant portion of our overall revenues and revenue 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, revenue from contracts with customers which have an original expected duration of one year or less are excluded from the amounts above.

| 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. The weighted average number of common shares outstanding has been reduced by our pro-rata weighted average interest in our own common shares of 6 million for the three and six months ended June 30, 2020 and 2019 , resulting from our reciprocal investment in Noverco Inc. (Noverco). DILUTED The treasury stock method is used to determine the dilutive impact of stock options. This method assumes any proceeds from the exercise of stock options 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 2020 2019 2020 2019 (number of common shares in millions) Weighted average shares outstanding 2,019 2,018 2,019 2,017 Effect of dilutive options 1 3 2 3 Diluted weighted average shares outstanding 2,020 2,021 2,021 2,020 For the three months ended June 30, 2020 and 2019 , 34.6 million and 21.3 million , respectively, anti-dilutive stock options with a weighted average exercise price of $51.00 and $53.33 , respectively, were excluded from the diluted earnings per common share calculation. For the six months ended June 30, 2020 and 2019 , 25.7 million and 15.9 million , respectively, anti-dilutive stock options with a weighted average exercise price of $52.71 and $53.99 , respectively, were excluded from the diluted earnings per common share calculation. DIVIDENDS PER SHARE On July 22, 2020, our Board of Directors declared the following quarterly dividends. All dividends are payable on September 1, 2020 to shareholders of record on August 14, 2020. Dividend per share Common Shares 1 $0.81000 Preference Shares, Series A $0.34375 Preference Shares, Series B $0.21340 Preference Shares, Series C 2 $0.16779 Preference Shares, Series D $0.27875 Preference Shares, Series F $0.29306 Preference Shares, Series H $0.27350 Preference Shares, Series J US$0.30540 Preference Shares, Series L US$0.30993 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 3 $0.24613 Preference Shares, Series 13 4 $0.19019 Preference Shares, Series 15 $0.27500 Preference Shares, Series 17 $0.32188 Preference Shares, Series 19 $0.30625 1 The quarterly dividend per common share was increased 9.8% to $0.81 from $0.738, effective March 1, 2020. 2 The quarterly dividend per share paid on Series C was decreased to $0.16779 from $0.25458 on June 1, 2020 and was increased to $0.25458 from $0.25305 on March 1, 2020, due to reset on a quarterly basis following the date of issuance of the Series C Preference Shares. 3 The quarterly dividend per share paid on Series 11 was decreased to $0.24613 from $0.275 on March 1, 2020, due to the reset of the annual dividend on March 1, 2020, and every five years thereafter. 4 The quarterly dividend per share paid on Series 13 was decreased to $0.19019 from $0.275 on June 1, 2020, due to the reset of the annual dividend on June 1, 2020, and every five years thereafter. |

| IMPAIRMENT OF EQUITY INVESTMENTS | IMPAIRMENT OF EQUITY INVESTMENTS For the six months ended June 30, 2020, we recorded a loss of $1,736 million resulting from an other than temporary impairment to the carrying value of our equity method investment in DCP Midstream, LLC (DCP Midstream). DCP Midstream holds a limited partner interest in and is the owner of the general partner of DCP Midstream, LP. The impairment in our equity investment is related to a decline in the market price of DCP Midstream, LP publicly-traded units as at March 31, 2020. In addition, we recorded a loss of $324 million from our equity pick up of the loss recorded by DCP Midstream in relation to DCP Midstream, LP's asset and goodwill impairment. This is recorded within Income from equity investments in the Consolidated Statements of Earnings. Our investment in DCP Midstream is part of the Gas Transmission and Midstream segment and our carrying value of the investment as at June 30, 2020 and December 31, 2019 was $325 million and $2,193 million |

| 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 (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 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 United States dollar denominated investments and subsidiaries using foreign currency derivatives and United States 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 program to significantly mitigate the impact of short-term interest rate volatility on interest expense via execution of floating to fixed interest rate swaps with an average swap rate of 2.9% . 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 June 30, 2020 , we do 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 within some of our subsidiaries to mitigate our exposure to long-term interest rate variability on select forecast term debt issuances via execution of floating to fixed interest rate swaps with an average swap rate of 3.1% . 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 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. COVID-19 PANDEMIC RISK The spread of the COVID-19 pandemic has caused significant volatility in Canada, the United States and international markets. While we have taken proactive measures to deliver energy safely and reliably during this pandemic, given the ongoing dynamic nature of the circumstances surrounding COVID-19, the impact of this pandemic on our business remains uncertain. TOTAL DERIVATIVE INSTRUMENTS The following table summarizes the Consolidated Statements of Financial Position location and carrying value of our derivative instruments. We generally have a policy of entering into individual International Swaps and Derivatives Association, Inc. 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 maximum potential settlement amounts in the event of these specific circumstances. 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 as well as 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 Statements of Comprehensive Income.

We estimate that a loss of $170 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 18 months as at June 30, 2020 . 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 2020 2019 2020 2019 (millions of Canadian dollars) Foreign exchange contracts 1 1,246 412 (757 ) 1,028 Interest rate contracts 2 3 — (15 ) 178 Commodity contracts 3 (517 ) 162 (44 ) (99 ) Other contracts 4 — — (8 ) 5 Total unrealized derivative fair value gain/(loss), net 732 574 (824 ) 1,112 1 For the respective six months ended periods, reported within Transportation and other services revenues ( 2020 - $437 million loss ; 2019 - $550 million gain ) and Net foreign currency gain/(loss) ( 2020 - $320 million loss ; 2019 - $478 million gain ) 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 six months ended periods, reported within Transportation and other services revenues ( 2020 - $17 million gain ; 2019 - $25 million loss ), Commodity sales ( 2020 - $403 million loss ; 2019 - $490 million loss ), Commodity costs ( 2020 - $348 million gain ; 2019 - $392 million gain ) and Operating and administrative expense ( 2020 - $6 million loss ; 2019 - $24 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. We also maintain current shelf prospectuses with securities regulators which enables ready access to either the Canadian or United States 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 June 30, 2020 . 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: June 30, December 31, (millions of Canadian dollars) Canadian financial institutions 125 146 United States financial institutions 127 40 European financial institutions 34 3 Asian financial institutions 135 92 Other 1 218 113 639 394 1 Other is comprised of commodity clearing house and physical natural gas and crude oil counterparties. As at June 30, 2020 , we provided letters of credit totaling nil in lieu of providing cash collateral to our counterparties pursuant to the terms of the relevant International Swaps and Derivatives Association agreements. We held no cash collateral on derivative asset exposures as at June 30, 2020 and December 31, 2019 . 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, credit risk is mitigated by the utilities' large and diversified customer base and the ability to recover an estimate for doubtful accounts 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 classify and provide for receivables older than 30 days as past due. 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 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 derivative 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 derivatives 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 derivative 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. Level 2 Level 2 includes derivative valuations determined using directly or indirectly observable inputs other than quoted prices included within Level 1. Derivatives 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 derivative. 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 held to maturity preferred share investment and long-term debt as Level 2. The fair value of our held to maturity preferred share investment is primarily based on the yield of certain Government of Canada bonds. The fair value of our long-term debt is based on quoted market prices for instruments of similar yield, credit risk and tenor. 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 extrapolation of observable future prices and rates. Derivatives valued using Level 3 inputs primarily include long-dated derivative power, crude, NGL and natural gas contracts, basis swaps, commodity swaps and energy swaps. 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. Depending on the type of derivative and nature of the underlying risk, we use observable market prices (interest, foreign exchange, commodity and share price) 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, 2020 Level 1 Level 2 Level 3 Total Gross Derivative Instruments (millions of Canadian dollars) Financial assets Current derivative assets Foreign exchange contracts — 73 — 73 Commodity contracts 15 47 215 277 15 120 215 350 Long-term derivative assets Foreign exchange contracts — 245 — 245 Commodity contracts 21 27 15 63 21 272 15 308 Financial liabilities Current derivative liabilities Foreign exchange contracts — (564 ) — (564 ) Interest rate contracts — (847 ) — (847 ) Commodity contracts (29 ) (16 ) (299 ) (344 ) Other contracts — (1 ) — (1 ) (29 ) (1,428 ) (299 ) (1,756 ) Long-term derivative liabilities Foreign exchange contracts — (1,524 ) — (1,524 ) Interest rate contracts — (390 ) — (390 ) Commodity contracts (12 ) (9 ) (59 ) (80 ) Other contracts — (6 ) — (6 ) (12 ) (1,929 ) (59 ) (2,000 ) Total net financial assets/(liabilities) Foreign exchange contracts — (1,770 ) — (1,770 ) Interest rate contracts — (1,237 ) — (1,237 ) Commodity contracts (5 ) 49 (128 ) (84 ) Other contracts — (7 ) — (7 ) (5 ) (2,965 ) (128 ) (3,098 ) December 31, 2019 Level 1 Level 2 Level 3 Total Gross Derivative Instruments (millions of Canadian dollars) Financial assets Current derivative assets Foreign exchange contracts — 161 — 161 Commodity contracts — 33 130 163 Other contracts — 4 — 4 — 198 130 328 Long-term derivative assets Foreign exchange contracts — 81 — 81 Commodity contracts — 12 5 17 Other contracts — 3 — 3 — 96 5 101 Financial liabilities Current derivative liabilities Foreign exchange contracts — (410 ) — (410 ) Interest rate contracts — (353 ) — (353 ) Commodity contracts (5 ) (23 ) (145 ) (173 ) (5 ) (786 ) (145 ) (936 ) Long-term derivative liabilities Foreign exchange contracts — (934 ) — (934 ) Interest rate contracts — (181 ) — (181 ) Commodity contracts — (6 ) (59 ) (65 ) — (1,121 ) (59 ) (1,180 ) Total net financial assets/(liabilities) Foreign exchange contracts — (1,102 ) — (1,102 ) Interest rate contracts — (534 ) — (534 ) Commodity contracts (5 ) 16 (69 ) (58 ) Other contracts — 7 — 7 (5 ) (1,613 ) (69 ) (1,687 ) The significant unobservable inputs used in the fair value measurement of Level 3 derivative instruments were as follows: June 30, 2020 Fair Value Unobservable Input Minimum Price Maximum Price Weighted Average Price Unit of Measurement (fair value in millions of Canadian dollars) Commodity contracts - financial 1 Natural gas (7 ) Forward gas price 1.96 5.24 3.22 $/mmbtu 2 Crude 16 Forward crude price 23.00 54.36 41.31 $/barrel Power (56 ) Forward power price 21.00 67.14 52.62 $/MW/H Commodity contracts - physical 1 Natural gas 17 Forward gas price 1.43 6.84 2.88 $/mmbtu 2 Crude (99 ) Forward crude price 33.45 74.06 50.63 $/barrel NGL 1 Forward NGL price 0.19 1.29 0.57 $/gallon (128 ) 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 2020 2019 (millions of Canadian dollars) Level 3 net derivative liability at beginning of period (69 ) (11 ) Total gain/(loss) unrealized Included in earnings 1 (107 ) 103 Included in OCI 7 (20 ) Settlements 41 (174 ) Level 3 net derivative liability at end of period (128 ) (102 ) 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, 2020 or December 31, 2019 . FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS Our other 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 other long-term investments totaled $56 million and $99 million as at June 30, 2020 and December 31, 2019 , respectively.

CHANGES IN ACCOUNTING POLICIES
| CHANGES IN ACCOUNTING POLICIES (Policies) | 6 Months Ended |
| Jun. 30, 2020 | |
| Accounting Standards Update and Change in Accounting Principle [Abstract] | |
| ADOPTION OF NEW ACCOUNTING STANDARDS and FUTURE ACCOUNTING POLICY CHANGES | ADOPTION OF NEW ACCOUNTING STANDARDS Clarifying Interaction between Collaborative Arrangements and Revenue from Contracts with Customers Effective January 1, 2020, we adopted Accounting Standards Update (ASU) 2018-18 on a retrospective basis. The new standard was issued in November 2018 to provide clarity on when transactions between entities in a collaborative arrangement should be accounted for under the new revenue standard, Accounting Standards Codification (ASC) 606. In determining whether transactions in collaborative arrangements should be accounted for under the revenue standard, the update specifies that entities shall apply unit of account guidance to identify distinct goods or services and whether such goods and services are separately identifiable from other promises in the contract. ASU 2018-18 also precludes entities from presenting transactions with a collaborative partner which are not in scope of the new revenue standard together with revenue from contracts with customers. The adoption of this ASU did not have a material impact on our consolidated financial statements. Disclosure Effectiveness Effective January 1, 2020, we adopted ASU 2018-13 on both a retrospective and prospective basis depending on the change. The new standard was issued to improve the disclosure requirements for fair value measurements by eliminating and modifying some disclosures, while also adding new disclosures. The adoption of this ASU did not have a material impact on our consolidated financial statements. Accounting for Credit Losses Effective January 1, 2020, we adopted ASU 2016-13 on a modified retrospective basis. The new standard was issued in June 2016 with the intent of providing financial statement users with more useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The previous accounting treatment used the incurred loss methodology for recognizing credit losses that delayed the recognition until it was probable a loss had been incurred. The accounting update adds a new impairment model, known as the current expected credit loss model, which is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the Financial Accounting Standards Board believes results in more timely recognition of such losses. Further, ASU 2018-19 was issued in November 2018 to clarify that operating lease receivables should be accounted for under the new leases standard, ASC 842, and are not within the scope of ASC 326, Financial Instruments - Credit Losses. For accounts receivable, a loss allowance matrix is utilized to measure lifetime expected credit losses. The matrix contemplates historical credit losses by age of receivables, adjusted for any forward-looking information and management expectations. Other loan receivables and off-balance sheet commitments in scope of the new standard utilize a discounted cash flow methodology which calculates the current expected credit losses based on historical default probability rates associated with the credit rating of the counterparty and the related term of the loan or commitment, adjusted for forward-looking information and management expectations. On January 1, 2020 we recorded $66 million of additional Deficit on our Statements of Financial Position in connection with the adoption of ASU 2016-13. The adoption of this ASU did not have a material impact on the Consolidated Statements of Earnings, Comprehensive Income or Cash Flows during the period. FUTURE ACCOUNTING POLICY CHANGES Reference Rate Reform ASU 2020-04 was issued in March 2020 to provide temporary optional guidance in accounting for reference rate reform. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles when accounting for contract modifications, hedging relationships and other transactions impacted by rate reform, subject to meeting certain criteria. ASU 2020-04 is effective as of March 12, 2020 through December 31, 2022. We had no transactions to which the ASU was applied since adoption and we are considering the impact of reference rate reform on our consolidated financial statements. Clarifying Interaction between Equity Securities, Equity Method Investments and Derivatives ASU 2020-01 was issued in January 2020 and clarifies that observable transactions should be considered for the purpose of applying the measurement alternative in accordance with ASC 321 immediately before the application or upon discontinuance of the equity method of accounting. Furthermore, the ASU clarifies that forward contracts or purchased options on equity securities are not out of scope of ASC 815 guidance only because, upon the contracts’ exercise, the equity securities could be accounted for under the equity method of accounting or fair value option. ASU 2020-01 is effective January 1, 2021 with early adoption permitted and is applied prospectively. The adoption of ASU 2020-01 is not expected to have a material impact on our consolidated financial statements. Accounting for Income Taxes ASU 2019-12 was issued in December 2019 with the intent of simplifying the accounting for income taxes. The accounting update removes certain exceptions to the general principles in ASC 740 as well as provides simplification by clarifying and amending existing guidance. ASU 2019-12 is effective January 1, 2021 and entities are permitted to adopt the standard early. We are currently assessing the impact of the new standard on our consolidated financial statements. Disclosure Effectiveness ASU 2018-14 was issued in August 2018 to improve disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The amendment modifies the current guidance by adding and removing several disclosure requirements while also clarifying the guidance on current disclosure requirements. ASU 2018-14 is effective January 1, 2021 and entities are permitted to adopt the standard early. The adoption of ASU 2018-14 is not expected to have a material impact on our consolidated financial statements. |
