Ottawa – July 31, 2025 – The Canadian Centre for Ethics in Sport (CCES) confirmed today that Martin Prinsloo, a U SPORTS volleyball athlete affiliated with York University, received a five-year sanction for an anti-doping rule violation. The athlete’s urine sample, collected in competition on March 7, 2025, revealed the presence of three prohibited anabolic agents: oxandrolone, stanozolol, and testosterone.
The standard sanction for a violation involving a prohibited substance is a four-year period of ineligibility; however, given the presence of multiple prohibited substances, the CCES asserted an additional two-year period of ineligibility for aggravating circumstances. On July 14, 2025, the athlete signed an Early Admission and Acceptance of Sanction Agreement, thereby admitting to the violation and accepting the asserted period of ineligibility and all other consequences. As a result, the otherwise applicable six-year period of ineligibility was reduced by one year in accordance with Canadian Anti-Doping Program (CADP) rule 10.8.1. Because a provisional suspension was imposed on the athlete, the sanction ends on April 13, 2030.
During the sanction period, the athlete is ineligible to participate in any capacity with any sport signatory to the CADP or the World Anti-Doping Code, including coaching and training with teammates
In compliance with rule 8.4 of the CADP, the CCES’s file outcome summary can be found in the Canadian Sport Sanction Registry.
