Overview

• The International Testing Agency notified Oleksiak on July 19 of her anti-doping code violation and she agreed to a voluntary provisional suspension.
• Oleksiak committed three whereabouts filing failures between October 2024 and June 2025 under the ADAMS tracking system.
• She and Swimming Canada insist the case stems from administrative oversights rather than any use of banned substances.
• Under World Aquatics and WADA rules, three missed or inaccurate location filings within 12 months constitute an anti-doping violation even without a positive drug test.
• A formal tribunal will decide whether her explanations suffice or if a multi-year suspension will be imposed, potentially affecting her future Olympic prospects.
