DISCLOSURE CONTROLS AND PROCEDURES

As of the end of the period covered by this report, an evaluation was carried out under the supervision of and with the participation of the Registrant’s management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operations of the Registrant’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the design and operation of these disclosure controls and procedures were effective in ensuring that information required to be disclosed by the Registrant in reports that it files with or submits to the Securities and Exchange Commission is recorded, processed, summarized and reported within the time periods required.

No significant changes were made in the Registrant’s internal control over financial reporting or in other factors during the period covered by this annual report on Form 40-F that have materially affected or are reasonably likely to materially affect the Registrant’s internal control over financial reporting.

INTERNAL CONTROL OVER FINANCIAL REPORTING

The information provided under the heading “Internal Control over Financial Reporting” contained in the Management’s Discussion and Analysis, filed as exhibit 99.5 to this annual report on Form 40-F, is incorporated herein by reference.

AUDIT COMMITTEE FINANCIAL EXPERT

The Registrant’s Board of Directors has determined that Mr. D.A. Leslie, a member of the Audit Committee, qualifies as an audit committee financial expert (as defined in Form 40-F under the Securities Exchange Act of 1934) and is independent as defined by the New York Stock Exchange corporate governance rules applicable to foreign private issuers. The SEC has indicated that the designation of Mr. Leslie as an audit committee financial expert does not make him an “expert” for any purpose, impose any duties, obligations or liability on him that are greater than those imposed on members of the audit committee and board of directors who do not carry this designation or affect the duties, obligations or liability of any other member of the audit committee.

CODE OF ETHICS

The Registrant has adopted a code of ethics (the “Statement on Business Conduct”) that applies to all employees and officers, including its principal executive officer, principal financial officer and principal accounting officer. The Statement on Business Conduct is available at the Registrant’s Internet website, www.enbridge.com.
