Penny Oleksiak, the most decorated female Olympian in Canadian history, has accepted a two-year ban from competitive swimming for an anti-doping rule violation.
The International Testing Agency (ITA) made the announcement on Tuesday after the seven-time Olympic medalist committed three residency errors between October 2024 and June 2025.
Oleksiak’s suspension ends on July 14, 2027, which is before the 2028 Summer Olympics in Los Angeles.

“We are committed to enforcing and supporting all anti-doping rules as outlined in the Canadian Anti-Doping Program and through World Aquatics and the World Anti-Doping Agency,” Swimming Canada CEO Suzanne Paulins said in a statement to ESPN. “While we accept Penny’s explanation that these were unintentional errors and she has not used banned substances, anti-doping rules are in place to ensure a level playing field for all athletes.

“We will miss Penny on the national team and hope to see her back in the pool when she is eligible.”
A whereabouts failure, as defined by the World Anti-Doping Code, is when a combination of three missed tests or submission failures occurs in a 12-month period.
Oleksiak was told by the ITA about the whereabouts case earlier this year, which ultimately led to her taking a temporary suspension in July. She withdrew from the World Aquatics Championships that month.

“I am and always have been a pure athlete and will not comment further at this time,” Oleksiak said in July 2025 when she withdrew from the World Aquatics Championships.
Oleksiak, 25, has won one gold, two silver and four bronze medals during his Olympic career. Her seven medals are tied for the most ever, male or female, with sprinter Andre De Grasse.
