The 2018 Canadian Open Mathematics Challenge — Nov 8/9


The Canadian Open Mathematics Challenge (COMC) is Canada's premier national mathematics competition that is 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.

Approximately the top 50 students from the COMC will be invited to write the Canadian Mathematical Olympiad (CMO). Students who excel in the CMO will have the opportunity to be selected as part of Math Team Canada -- a small team of students who travel to compete in the International Mathematical Olympiad (IMO). Depending on grade level and performance, students participating in the COMC can also have opportunities to garner awards, to win prizes, to be considered for scholarships, and to get invited to camps.

Thank you for participating in the 2018 COMC!

The 2018 exam paper (PDF) is available for download.


The exams are currently being marked and verified. Teachers will be notified by email once the preliminary scores become available. Scores will be posted to your COMC online account.

An e-mail will be sent out to teachers in early December asking for confirmation of spellings (including punctuation and capitalization) of school and student information, so that any issued awards, certificates and plaques will be correct.

We anticipate preliminary scores will be available to teachers in late December, before students leave for the holidays. Final scores, award winners, and prize draw recipients will be announced publicly in early January.

Teachers can log in to their school accounts at any time.

Stay informed!
