Overview

CLMC -> COMC -> CMO -> IMO

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. 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!

Depending on their grade level and performance, students participating in the COMC will also have the opportunity to be considered for university scholarships, get invited to math camps, garner awards, and win prizes.

CMO Qualifier: The results of the COMC matter!  Approximately 100 – 120 top-ranking students from the COMC are invited to write the Canadian Mathematical Olympiad (CMO) or the Junior CMO (CJMO) in March.  The CMO, in turn, is a qualifier for Team Canada at the International Mathematical Olympiad (IMO) held in a different city each July.

EGMO Qualifier: The top 6 – 8 COMC female contestants will also qualify for selection to represent Canada at the European Girls’ Mathematical Olympiad (EGMO). EGMO is an international mathematics competition held each April in a European host city each year.

APMO Qualifier: Approximately 10 – 20 top-ranking students from the COMC are also selected to write the Asia-Pacific Mathematical Olympiad (APMO) as Team Canada.
