Disclosure controls and procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed in reports filed or submitted by the Company under U.S. and Canadian securities legislation is recorded, processed, summarized and reported within the time periods specified in those rules, including providing reasonable assurance that material information is gathered and reported to senior management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to permit timely decisions regarding public disclosure. Management, including the CEO and CFO, has evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) of the U.S. Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules of Canadian Securities Administration, as of August 31, 2024. Based on this evaluation, the CEO and CFO have concluded that the Company’s disclosure controls and procedures were effective.

Internal control over financial reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) and 15d-15(f) of the Exchange Act and National Instrument 52-109 Certification of Disclosure in Issuer’s Annual and Interim filings. Any system of internal control over financial reporting, no matter how well designed, has inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Changes in internal control over financial reporting

There have been no changes in our internal controls over financial reporting during the fiscal quarter ended August 31, 2024 which have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. We continue to evaluate our internal control over financial reporting on an ongoing basis to identify improvements.
