Canadian Open Mathematics Challenge

The Canadian Open Mathematics Challenge (COMC) is an annual mathematics competition held in Canada during the month of November. This competition is run by the Canadian Mathematical Society and sponsored by Sun Life Financial. Students who score exceptionally well on this competition are selected to participate in the Canadian Mathematical Olympiad.

The COMC is written on a select day in November each year and is proctored by teachers across Canada. In order to participate in this competition, students must register through their school’s mathematics department and pay any fees associated with the competition. Following the day of the competition, exams are returned to a network of university partners across Canada for marking.

The competition is open to any student with an interest in mathematics. However, to be eligible for awards participants in the COMC must satisfy the following criteria:

Students writing from outside Canada are not considered for awards or CMO eligibility unless proof of citizenship (or permanent residency) is provided.

Students not meeting the qualification requirements can still participate and marks as “unofficial” competitors.

The COMC consists of three sections:

for a total of 80 marks.

The length of the contest is 2.5 hours. Calculators are not permitted.

There are two divisions: Canadian Awards, which is only for participants writing the exam from within Canada; and International Awards, which is only for participants writing it outside of Canada.

Canadian Award Categories

There are award categories for Best in Canada and Best in Province and Best in Region for all students as well as for students at each grade. For example:

The top six unique scores in any category earn awards: Gold, Silver, Bronze, Honourable Mention.

International Awards

The top official participants from outside Canada are considered for the international awards division, which is not grade-dependent. The top three unique scores are given Gold, Silver or Bronze. Additionally, any international student who achieves at least a score as high as the lowest Best in Canada Overall Honourable Mention will receive an Honourable Mention award in the International division.

Invitational Competitions and Math Team Canada

The top students who are Canadian Citizens or Permanent Residents (independent of grade or where they live or attend school) will be invited to participate in the Sun Life Financial Canadian Mathematical Olympiad (CMO) competition. Students who perform well on the CMO are selected for Math Team Canada, which represents Canada at the International Math Olympiad (IMO) the following summer.
