Auditor Opinion [Text Block] We have audited the accompanying consolidated balance sheets of BriaCell Therapeutics Corp. (the Company) as at July 31, 2025 and 2024, and the related consolidated statements of operations and comprehensive loss, changes in shareholders’ equity (deficit), and cash flows for each of the years in the two-year period ended July 31, 2025, and the related notes (collectively referred to as the consolidated financial statements). 

In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position at the Company as of July 31, 2025 and 2024, and the results of its consolidated operations and its consolidated cash flows for each of the years in the two-year period ended July 31, 2025, in conformity with accounting principles generally accepted in the United States of America.
