The 2020 Prohibited List is Now in Effect

(Ottawa, Ontario – January 6, 2020) – The Canadian Centre for Ethics in Sport (CCES) reminds the Canadian sport community that the World Anti-Doping Agency’s (WADA) 2020 Prohibited List came into effect January 1, 2020.

The 2020 Prohibited List and the Summary of Major Modifications and Explanatory Notes, which contains an exhaustive list of changes, are available on WADA’s website. As always, athletes are cautioned to exercise a high degree of care with regards to the use of medications, supplements and sport nutrition products. The following CCES resources can help athletes determine whether medications are prohibited in sport. These resources now reflect the 2020 List.

Athletes who require a prohibited medication should verify their medical exemption requirements in the Medical Exemption Wizard.
