Canadian Mathematical Society Competitions

CMS Competitions are run by the CMS Executive Office and the CMS Competition Committees

Competitions are an important part of learning mathematics and a fun activity for students of all ages. The CMS supports math competitions in many ways, from running our own competitions to funding regional competitions to supporting Canadian involvement in international competitions. We also provide a wide variety of resources for students to prepare for competitions. 

Supported by the Actuarial Profession

Canadian Mathematical Gray Jay Competition (CMGC)

Canadian Mathematical Gray Jay Competition (CMGC) is a new Canadian math competition open to students in grades K-8, with questions based primarily on grade 5-8 curriculum. This competition has been created by mathematicians from across Canada.

Canadian Open Mathematics Challenge (COMC)

The Canadian Open Mathematics Challenge (COMC) is Canada’s premier national mathematics competition open to any student with an interest in and grasp of high school math. It is also the first exam on the road to the International Mathematical Olympiad. The purpose of the COMC is to encourage students to explore, discover, and learn more about mathematics and problem solving. The competition serves to provide teachers with a unique student enrichment activity during the fall term. The COMC is the first step on the road to the IMO. 

The Canadian Mathematical Olympiad Qualifying Repêchage (CMOQR or just Repêchage) is an invitation-only contest that serves as a qualifier for the Canadian Mathematical Olympiad (CMO).

Students participating in the Repêchage receive a set of problems whose solutions must be submitted within a week of receipt. Students who do well on the Repêchage are then invited to write the CMO.

The Canadian Mathematical Olympiad (CMO) is Canada’s premier national advanced mathematics competition. Candidates require an invitation from the Canadian Mathematical Society in order to participate.

Candidates require an invitation from the Canadian Mathematical Society in order to participate:

  1. The Canadian Open Mathematics Challenge (COMC) is the main qualifier for the CMO. Normally, the top 50 qualifying students from the COMC receive a direct invitation to write the CMO.
  2. Approximately the top 15-20 competitors from the CMO Qualifying Repêchage (CMOQR) earn invitations to the CMO.
  3. Normally, the top 3 students from the Alberta High School Mathematics Competition (Part II) and le Concours de l’Association Mathématique du Québec are invited to write the CMO.

Canadian Junior Mathematical Olympiad (CJMO)

The Canadian Junior Mathematical Olympiad (CJMO) is an Olympiad style competition for younger students. Like for the CMO, the invitation to the CJMO is based on the results of the COMC and the Repêchage. Invitees will be the top students in grade 10 and below. Invitations to the CJMO are sent out after the Repêchage has been graded. The CJMO exam is written at the same time as the CMO.

Thanks to our sponsors, the CMS is now able to support the participation of underrepresented groups including low income Canadians and indigenous peoples. The CMS will do this by covering the cost of the exams.

Part of the Society’s mission is to ensure that mathematics is available to all regardless of their region of residence and their socioeconomic status. We hope this will allow mathematics to spread to more remote communities and anyone with a passion for mathematics.

This opportunity has been made possible by Royal Bank of Canada and Natural Sciences and Engineering Research Council of Canada (NSERC).
