CONTROLS AND PROCEDURES
Disclosure Controls and Procedures
Disclosure controls and procedures are defined in Rule 13a-15(e) under the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”), to mean controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the United States Securities and Exchange Commission’s (the “Commission”) rules and forms.
At the direction of Hydro One Limited’s (the “Registrant”) Chief Executive Officer and Chief Financial Officer, management evaluated disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, management concluded that the Registrant’s disclosure controls and procedures were effective as at December 31, 2023.
See the disclosure provided under the heading “Disclosure Controls and Procedures and Internal Control over Financial Reporting” on page 35 of Exhibit 99.3, the Registrant’s Management’s Discussion and Analysis (the “MD&A”) which is incorporated by reference herein.
Management’s Annual Report on Internal Control over Financial Reporting and Attestation Report of the Registered Public Accounting Firm
Management is responsible for establishing and maintaining adequate disclosure controls and procedures and internal control over financial reporting as described in the MD&A. Management evaluated the effectiveness of the design and operation of internal control over financial reporting based on the framework and criteria established in the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation, management concluded that the Registrant's internal control over financial reporting was effective as of December 31, 2023.
Internal control, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and due to its inherent limitations, may not prevent or detect all misrepresentations. Furthermore, the effectiveness of internal control is affected by change and subject to the risk that internal control effectiveness may change over time.
This annual report does not include an attestation report of the Registrant’s registered public accounting firm regarding internal control over financial reporting.
The report of management on our internal control over financial reporting is provided under the heading “Management’s Report” in the Registrant’s audited consolidated financial statements, which is filed as Exhibit 99.2 and is incorporated by reference herein.
Changes in Internal Control Over Financial Reporting
There were no significant changes in the design of the Registrant’s internal control over financial reporting during the year ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, the operation of the Registrant’s internal control over financial reporting.







IDENTIFICATION OF THE AUDIT COMMITTEE
The Registrant has a separately-designated standing audit committee established in accordance with Section 3(a)(58)(A) of the Exchange Act (the “Audit Committee”). The Audit Committee comprises Stacey Mowbray (Chair), Mitch Panciuk, Helga Reidel, Brian Vaasjo, and Mark Podlasly. The board of directors of the Registrant has determined that each member of the Audit Committee is “independent” as defined in the Exchange Act and the New York Stock Exchange’s listing standards applicable to the Registrant. Each of the Audit Committee members has an understanding of the accounting principles used to prepare the Registrant’s financial statements and varied experience as to the general application of such accounting principles, as well as an understanding of the internal controls and procedures necessary for financial reporting.
AUDIT COMMITTEE FINANCIAL EXPERT
The board of directors of the Registrant has determined that it has at least one audit committee financial expert serving on its audit committee. Stacey Mowbray, Mitch Panciuk, Mark Podlasly, Helga Reidel and Brian Vaasjo have each been designated as an audit committee financial expert and are each independent, as such term is defined in the New York Stock Exchange’s listing standards applicable to the Registrant. The Commission has indicated that the designation or identification of an audit committee financial expert does not deem that audit committee financial expert an “expert” for any purpose, impose any duties, obligations or liability on such audit committee financial expert that are greater than those imposed on members of the audit committee and board of directors who do not carry this designation or identification, or affect the duties, obligations or liability of any other member of the audit committee or board of directors.
AUDIT COMMITTEE PRE-APPROVAL POLICIES AND PROCEDURES
The charter of the Audit Committee requires that the Audit Committee review and approve all policies and procedures for the pre-approval of services to be rendered by external auditors. All permissible non-audit services to be provided to the Registrant or any of its affiliates by external auditors or any of their affiliates that are not covered by pre-approval policies and procedures approved by the Audit Committee, are subject to pre-approval by the Audit Committee. During the fiscal year ended December 31, 2023, the waiver of pre-approval provisions set forth in the applicable rules of the Commission was not utilized for any services related to Audit-Related Fees, Tax Fees or All Other Fees and the Audit Committee did not approve any such fees subject to the waiver of pre-approval provisions.
