OTTAWA, ON – The Canadian Mathematical Society (CMS) is pleased to announce the results of the 2023 Canadian Open Mathematics Challenge (COMC). Over 6000 students wrote the COMC on October 26, 2023. Furthermore, thanks to ongoing collaboration with CMS’ International Competition Partners, more than 700 international students were able to take the COMC.

The Chair of the COMC committee, Dr. Robert Woodrow (University of Calgary) is pleased with the results of the competition:

The 2023 Canadian Open Mathematics Challenge saw increased participation with over 6276 exams submitted to be marked. Our marking partners rose to the challenge and completed the task on schedule. […] This year, […] 8 papers received 80/80 – four from the Canadian Division, and four from the International Division. Being able to distinguish prize winners means that inevitably the Challenge has questions that not everyone can do easily. […] We found many interesting and creative solutions, and indications that participants welcomed the challenge.

This year, eight students obtained a perfect score of 80/80. Congratulations! The median score for all participants of all grades and locations was 36/80. Further statistics are available on the COMC web site.

In addition to the valuable support received from the Society’s sponsors and academic partners, the CMS is also grateful for the support, participation and cooperation of all members, individual donors, as well as parents, teachers, schools and school boards.

The COMC is a prestigious exam and requires involvement by our university partners from coast to coast.  Whether they proctored, scanned and/or marked the exams, we thank the following institutions for their commitment to mathematical excellence in Canada:

  • University of British Columbia
  • University of Calgary
  • MacEwan University
  • University of Regina
  • University of Saskatchewan
  • University of Manitoba
  • University of Toronto
  • York University
  • University of Ottawa

About the COMC
The COMC is Canada’s premier national mathematics competition open to any student with an interest in and grasp of high school math.  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. It is the most prestigious math competition in Canada, and one of the most prestigious in the Americas. The COMC is the only way to be invited to the CMS’ free, exclusive training camps and compete internationally as part of Math Team Canada!

The very top-performing eligible COMC participants will be invited to participate in the Canadian Mathematical Olympiad (CMO)  in March. Students can also qualify to write the CMO through the CMO Qualifying Repêchage which will take place from January 31st to February 7th, 2024. Approximately 100 students are selected to write the CMO.  The best performing students at the CMO are then invited to represent Canada at the International Mathematical Olympiad (IMO) this July. The COMC also provides opportunities to be selected for the Canadian Team to the European Girls’ Mathematical Olympiad (EGMO).


About the Canadian Mathematical Society (CMS)
Founded in 1945, the Canadian Mathematical Society (CMS) promotes the advancement, discovery, learning and application of mathematics. The CMS promotes mathematics through a rich array of activities including scientific meetings, publications, awards, prizes, grants, camps and competitions.
