18 July 2025, Lausanne – The Aquatics Integrity Unit (AQIU) acknowledges the decision of the International Testing Agency (ITA) to notify Canadian swimmer Penelope Oleksiak of an apparent Anti-Doping Rule Violation, pursuant to Article 2.4 of the World Aquatics Doping Control Rules, namely the occurrence of three (or more) Whereabouts Failures within a twelve-month period.* Pending the resolution of this matter, Ms. Oleksiak has voluntarily accepted a provisional suspension. Given that the case is underway, there will be no further comments during the ongoing proceedings. 

*Athletes included in a Registered Testing Pool (“RTP”), such as Penelope Oleksiak, have the obligation to provide daily whereabouts as well as a specific daily 60-minute time slot where they will be available for testing. The purpose is to allow Anti-Doping Organisations to locate athletes for unannounced Out-of-Competition Testing. Any combination of three (or more) Missed Tests (which relate to the Athletes’ unavailability with respect to their 60-minute time slot) and/or Filing Failures (which are caused by the Athletes’ failure to provide accurate Whereabouts) committed within a twelve-month period amount to a potential Anti-Doping Rule Violation (“ADRV”) as per Article 2.4 of the World Aquatics Doping Control Rules and World Anti-Doping Code.
