SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

The prospectus and this prospectus supplement, including the documents incorporated by reference into the prospectus and this prospectus
supplement, contain both historical and forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933, as
amended (the "U.S. Securities Act"), and Section 21E of the U.S. Securities Exchange Act of 1934, as amended (the "U.S. Exchange Act"), and
forward-looking information within the meaning of Canadian securities laws (collectively, "forward-looking statements"). This information has
been included to provide readers with information about the Corporation and its subsidiaries and affiliates, including management's assessment of
the Corporation's and its subsidiaries' future plans and operations. This information may not be appropriate for other purposes. Forward-looking
statements are typically identified by words such as "anticipate", "believe", "estimate", "expect", "forecast", "intend", "likely", "plan", "project",
"target" and similar words suggesting future outcomes or statements regarding an outlook. Forward-looking information or statements included or
incorporated by reference in the prospectus and this prospectus supplement include, but are not limited to, statements with respect to the following:
expected earnings before interest, income taxes and depreciation and amortization ("EBITDA"); expected earnings/(loss); expected earnings/(loss)
per share; expected future cash flows; expected performance of the Liquids Pipelines, Gas Transmission and Midstream, Gas Distribution,
Renewable Power Generation and Transmission, and Energy Services businesses; financial strength and flexibility; expectations on sources of
liquidity and sufficiency of financial resources; expected costs related to announced projects and projects under construction; expected in-service
dates for announced projects and projects under construction; expected capital expenditures; expected equity funding requirements for the
Corporation's commercially secured growth program; expected future growth and expansion opportunities; expectations about the Corporation's
joint venture partners' ability to complete and finance projects under construction; expected closing of acquisitions and dispositions and expected
timing thereof; estimated future dividends; expected future actions of regulators and related court proceedings; expected costs related to leak
remediation and potential insurance recoveries; expectations regarding commodity prices; supply forecasts; this offering, including the closing date
thereof, the expected use of proceeds and the Corporation's intention to not list the Notes on any stock exchange or other market; expectations
regarding the impact of the stock-for-stock merger transaction completed on February 27, 2017 between Enbridge and Spectra Energy Corp (the
"Merger Transaction") including the combined Corporation's scale, financial flexibility, growth program, future business prospects and
performance; United States Line 3 Replacement Program; the expected in-service date of the Canadian Line 3 Replacement Program; Line 5
related matters; Mainline System contracting; expected impact of the Federal Energy Regulatory Commission policy on treatment of income taxes;
the transactions undertaken to simplify the Corporation's corporate structure; the Corporation's dividend payout policy; dividend growth and
dividend payout expectation; expectations on impact of the Corporation's hedging program; and expectations resulting from the successful
execution of the Corporation's 2018-2020 Strategic Plan.

Although the Corporation believes these forward-looking statements are reasonable based on the information available on the date such
statements are made and processes used to prepare the information, such statements are not guarantees of future performance and readers are
cautioned against placing undue reliance on forward-looking statements. By their nature, these statements involve a variety of assumptions, known
and unknown risks and uncertainties and other factors, which may cause actual results, levels of activity and achievements to differ materially from
those expressed or implied by such statements. Material assumptions include assumptions about the following: the expected supply of and demand
for crude oil, natural gas, natural gas liquids ("NGL") and renewable energy; prices of crude oil, natural gas, NGL and renewable energy; exchange
rates; inflation; interest rates; availability and price of labor and construction materials; operational reliability; customer and regulatory approvals;
maintenance of support and regulatory approvals for the Corporation's projects; anticipated in-service dates; weather; the timing and closing of
dispositions and of this offering; the realization of anticipated benefits and synergies of the Merger Transaction; governmental legislation;
https://www.sec.gov/Archives/edgar/data/880285/000110465919064346/a19-22424_1424b5.htm[11/15/2019 8:59:23 AM]

acquisitions and the timing thereof; the success of integration plans; impact of the dividend policy on the Corporation's future cash flows; credit
ratings; capital project funding; expected EBITDA; expected earnings/(loss); earnings/(loss) per share; future cash flows; and estimated future
dividends. Assumptions regarding the expected supply of and demand for crude oil, natural gas, NGL and renewable energy, and the prices of these
commodities, are material to and underlie all forward-looking statements, as they may impact current and future levels of demand for the
Corporation's services. Similarly, exchange rates, inflation and interest rates impact the economies and business environments in which the
Corporation operates and may impact levels of demand for the Corporation's services and cost of inputs, and are therefore inherent in all forward-
looking statements. Due to the

S-v
Table of Contents

interdependencies and correlation of these macroeconomic factors, the impact of any one assumption on a forward-looking statement cannot be
determined with certainty, particularly with respect to the impact of the Merger Transaction on the Corporation, expected EBITDA, earnings/(loss),
earnings/(loss) per share, or estimated future dividends. The most relevant assumptions associated with forward-looking statements regarding
announced projects and projects under construction, including estimated completion dates and expected capital expenditures, include the following:
the availability and price of labor and construction materials; the effects of inflation and foreign exchange rates on labor and material costs; the
effects of interest rates on borrowing costs; the impact of weather; and customer, government and regulatory approvals on construction and in-
service schedules and cost recovery regimes.

The Corporation's forward-looking statements are subject to risks and uncertainties pertaining to the realization of anticipated benefits
and synergies of the Merger Transaction, operating performance, regulatory parameters, changes in regulations applicable to the Corporation's
business, dispositions, the transactions undertaken to simplify the Corporation's corporate structure dividend policy, project approval and support,
renewals of rights of way, weather, economic and competitive conditions, public opinion, changes in tax laws and tax rates, changes in trade
agreements, exchange rates, interest rates, commodity prices, political decisions and supply of and demand for commodities, including but not
limited to those risks and uncertainties discussed in the prospectus, this prospectus supplement and in documents incorporated by reference into the
prospectus and this prospectus supplement. The impact of any one risk, uncertainty or factor on a particular forward-looking statement is not
determinable with certainty as these are interdependent and the Corporation's future course of action depends on management's assessment of all
information available at the relevant time. Except to the extent required by applicable law, the Corporation assumes no obligation to publicly
update or revise any forward-looking statements made in the prospectus and this prospectus supplement or otherwise, whether as a result of new
information, future events or otherwise. All subsequent forward-looking statements, whether written or oral, attributable to the Corporation or
persons acting on the Corporation's behalf, are expressly qualified in their entirety by these cautionary statements.

For more information on forward-looking statements, the assumptions underlying them, and the risks and uncertainties affecting them,
see "Note Regarding Forward-Looking Statements" in the prospectus and "Risk Factors" in this prospectus supplement and the prospectus.

each of the Guarantors and will rank equally with all other existing and
future unsecured and unsubordinated indebtedness of that Guarantor,
other than preferred claims imposed by statute.

Pursuant to the Indenture (as defined herein) governing the Notes, the
guarantees of either Guarantor will be unconditionally released and
discharged automatically upon the occurrence of certain events as
described under "Description of the Notes and the Guarantees --
Guarantees" in this prospectus supplement.

Optional Redemption
We may redeem some or all of the Notes of each series at any time. If
the redemption date in respect of any 2025 Notes is more than one
month prior to the maturity date of the 2025 Notes, if the redemption
date in respect of any 2029 Notes is more than three months prior to the
maturity date of the 2029 Notes, or if the redemption date in respect of
any 2049 Notes is more than six months prior to the maturity date of the
2049 Notes, then the redemption price will equal the applicable "make-
whole" price described in this prospectus supplement under
"Description of the Notes and the Guarantees -- Redemption --
Optional Redemption", plus accrued and unpaid interest to the
redemption date. If the redemption date in respect of any 2025 Notes is
on or after the date that is one month prior to the maturity date of the
2025 Notes, if the redemption date in respect of any 2029 Notes is on or
after the date that is three months prior to the maturity date of the 2029
Notes or if the redemption date in respect of any 2049 Notes is on or
after the date that is six months prior to the maturity date of the 2049
Notes, then the redemption price will equal 100% of the principal
amount of the Notes being redeemed, plus accrued and unpaid interest
to the redemption date.

Change in Tax Redemption
We may redeem the Notes of any series in whole, but not in part, at the
redemption price equal to the principal amount of Notes being
redeemed, plus accrued and unpaid interest to the redemption date, at
any time in the event certain changes affecting Canadian withholding
taxes occur. See "Description of the Notes and the Guarantees --
Redemption -- Tax Redemption" in this prospectus supplement.

Sinking Fund
The Notes will not be entitled to the benefit of a sinking fund.

Use of Proceeds
We estimate that the net proceeds of the offering of the Notes, after
deducting underwriting discounts and commissions and the estimated
expenses of the offering, will be approximately US$1,978,355,000. We
intend to use the net proceeds of this offering to refinance, redeem or
repurchase existing indebtedness of the Corporation or its subsidiaries
and, if applicable, for other general corporate purposes of the
Corporation and its affiliates. See "Use of Proceeds" in this prospectus
supplement.

Additional Amounts
Any payments made by us with respect to the Notes of a series will be
made without withholding or deduction for Canadian taxes unless
required to be withheld or deducted by law or by the interpretation or

administration thereof. If we are so required to withhold or deduct for
Canadian taxes with respect to a payment to the holders of Notes of a
series, we will pay the additional amounts necessary so that the net
amounts received by the holders of those Notes after the withholding or
deduction is not less than the amounts that those holders would have
received in the absence of the withholding or deduction. See
"Description of the Notes and the Guarantees -- Payment of Additional
Amounts" in this prospectus supplement.

Form
The Notes will be represented by fully registered global Notes deposited
in book-entry form with, or on behalf of, The Depository Trust
Company, and registered in the name of its nominee. See "Description
of the Note and the Guarantees -- Book-Entry System" in this
prospectus supplement. Except as described under "Description of the
Notes and the Guarantees" in this prospectus supplement, Notes in
certificated form will not be issued.

Trustee and Paying Agent
Deutsche Bank Trust Company Americas.

Governing Law
The Notes and the related guarantees will be, and the Indenture is,
governed by the laws of the State of New York.

Risk Factors
Investing in the Notes involves risks. See "Risk Factors" beginning on
page S-6 of this prospectus supplement for a discussion of factors that
you should refer to and carefully consider before deciding to invest in
these Notes.

Lack of Public Market for the Notes
The Notes are a new issue of securities with no established trading
market. We do not intend to apply for listing of the Notes on any
securities exchange. The underwriters have advised us that they intend
to make a market in the Notes as permitted by applicable laws and
regulations; however, the underwriters are not obligated to make a
market in the Notes, and they may discontinue their market-making
activities at any time without notice.

Conflicts of Interest
We may have outstanding existing indebtedness owing to certain of the
underwriters and affiliates of the underwriters, a portion of which we
may repay with the net proceeds of this

offering. See "Use of Proceeds" in this prospectus supplement. As a
result, one or more of the underwriters or their affiliates may receive
more than 5% of the net proceeds from this offering in the form of the
repayment of existing indebtedness. Accordingly, this offering is being
made pursuant to Rule 5121 of the Financial Industry Regulatory
Authority, Inc. Pursuant to this rule, the appointment of a qualified
independent underwriter is not necessary in connection with this
offering, because the conditions of Rule 5121(a)(1)(C) are satisfied.

RISK FACTORS

You should consider carefully the following risks and other information contained in and incorporated by reference into this prospectus
supplement and the accompanying prospectus before deciding to invest in the Notes of any series. In particular, we urge you to consider carefully
https://www.sec.gov/Archives/edgar/data/880285/000110465919064346/a19-22424_1424b5.htm[11/15/2019 8:59:23 AM]

the following risk factors, as well as the risk factors set forth under the heading "Item 1A. Risk Factors" in the Corporation's Annual Report on
Form 10-K for the fiscal year ended December 31, 2018, incorporated by reference into this prospectus supplement and the accompanying
prospectus. The following risks and uncertainties could materially and adversely affect our financial condition and results of operations. In that
event, the value of our securities, including the Notes, or our ability to meet our obligations under the Notes, may be adversely affected.

Risks Related to the Notes

We are a holding company and as a result are dependent on our subsidiaries to generate sufficient cash and distribute cash to us to service our
indebtedness, including the Notes.

Our ability to make payments on our indebtedness, fund our ongoing operations and invest in capital expenditures and any acquisitions
will depend on our subsidiaries' (including subsidiary partnerships and joint-ventures through which we conduct business) ability to generate cash
in the future and distribute that cash to us. It is possible that our subsidiaries may not generate cash from operations in an amount sufficient to
enable us to service our indebtedness, including the Notes of any series. The Notes are U.S. dollar-denominated obligations and a substantial
portion of our subsidiaries' revenues are denominated in Canadian dollars. Fluctuations in the exchange rate between the U.S. and Canadian
dollars may adversely affect our ability to service or refinance our U.S. dollar-denominated indebtedness, including the Notes.

The Notes are structurally subordinated to the indebtedness of our non-Guarantor subsidiaries.

The Notes are not guaranteed by our subsidiaries (including subsidiary partnerships and joint ventures through which we conduct
business) that are not Guarantors and are thus structurally subordinated to all of the debt of these subsidiaries. Additionally, each of the Guarantors
will be released from its guarantees following the repayment in full or discharge or defeasance of the Guarantor's debt securities outstanding as of
January 22, 2019, or upon the occurrence of certain other events, as described under "Description of the Notes and the Guarantees -- Guarantees"
in this prospectus supplement, in which case the Notes will be structurally subordinated to all of the debt of that former guarantor subsidiary. The
Corporation's interests in its subsidiaries and the partnerships and joint ventures through which it conducts business generally consist of equity
interests, which are residual claims on the assets of those entities after their creditors are satisfied. As at September 30, 2019, the long-term debt
(excluding current portion, as well as guarantees and intercompany obligations between the Corporation and its subsidiaries) of the subsidiaries of
the Corporation other than the Guarantors totaled approximately $26,593 million.

The Indenture restricts our ability to incur liens, but places no such restriction on our subsidiaries or the partnerships and joint ventures
through which we conduct business. Holders of parent company indebtedness that is secured by parent company assets will have a claim on the
assets securing the indebtedness that is prior in right of payment to our general unsecured creditors, including you as a holder of the Notes (a
"Noteholder"). The Indenture permits us to incur additional liens as described under "Description of the Notes and the Guarantees -- Covenants --
Limitation on Security Interests" in this prospectus supplement.

Your right to receive payments on the Notes is effectively subordinate to those lenders who have a security interest in the assets of the
Corporation or the Guarantors.

The Notes and the guarantees are unsecured. The Corporation or the Guarantors may incur indebtedness that is secured by certain or
substantially all of their respective tangible and intangible assets, including the equity interests of each of their existing and future subsidiaries. If
the Corporation or the Guarantors were unable to repay any such secured indebtedness, the creditors of those obligations could foreclose on the
pledged assets to the exclusion of holders of the Notes, even if an event of default exists under the Indenture at such time. As at September 30,
2019,

SEP had approximately $146 million of secured indebtedness outstanding and EEP had no secured indebtedness outstanding.

We may redeem the Notes before they mature.

The Corporation may redeem the Notes of any series in the circumstances described under "Description of the Notes and the Guarantees
-- Redemption -- Optional Redemption" in this prospectus supplement and the Corporation may redeem the Notes of any series in the
circumstances described under "Description of the Notes and the Guarantees -- Redemption -- Tax Redemption" in this prospectus supplement.
These redemption rights may, depending on prevailing market conditions at the time, create reinvestment risk for the Noteholders of a series of
Notes in that they may be unable to find a suitable replacement investment with a comparable return to those Notes.

Federal and state statutes allow courts, under specific circumstances, to void the guarantees of the Notes by our Guarantors and require the
holders of the Notes to return payments received from the Guarantors.
