The CMS wishes to thank the sponsors and partners who make our competitions program successful.

The Canadian Mathematical Olympiad Qualifying Repêchage (or just “Repêchage”) is an annual competition that serves as a qualifier for the Canadian Mathematical Olympiad (CMO).  It typically runs at the end of January or beginning of February each year, shortly after results of the COMC are announced.

Participants in the Repêchage receive a set of problems whose solutions must be submitted within a week of receipt. The Repêchage is a take home competition.  The solution papers returned to the CMS are carefully reviewed, but not explicitly scored.  The students who demonstrate the most innovative, clear and complete solutions are chosen for CMO invitations and the others are thanked for participating.  There are no other prizes nor certificates for participation.

2022 Competition

The 2022 Repêchage will take place during the week of February 15-22, 2022.

By Invitation Only

Students who participated in the Canadian Open Mathematics Challenge (COMC) and did well, but did not qualify for the CMO, are invited to write the Repêchage. If students do well, they will earn an invitation to the CMO.  In a typical year, about 75 students are invited to the Repêchage.  Based on results, approximately 20 of these students are selected and provided invitations to the top national math competition: the Canadian Mathematical Olympiad (CMO).


Students invited to write the Repêchage must complete a declaration that they meet the eligibility requirements to write the CMO. The CMO eligibility requirements are listed on the CMO page.

Preparing for the Repêchage

In addition to the past Repêchage test papers, students are encouraged to use past COMC and CMO papers to help prepare for the Repêchage. The CMS also has many problem-solving resources available for competitors.
