Canadian Open Mathematics Challenge (COMC)
Canada’s premier national math contest, preparing students for the Canadian Mathematical Olympiad (CMO) and the International Mathematical Olympiad (IMO).
Canada’s premier national math contest that builds a direct pathway to scholarships and top university admissions.
Visit Official COMC Contest Page →The Canadian Open Mathematics Challenge (COMC), hosted by the Canadian Mathematical Society (CMS), is Canada’s most prestigious national mathematics competition for high school students. It serves as the qualifier for the Canadian Mathematical Olympiad (CMO), and ultimately the International Mathematical Olympiad (IMO).
The contest is proof-based, requiring students to explain solutions clearly, not just compute answers. Top scorers often receive recognition that directly supports admission and scholarships at universities like the University of Waterloo, McGill, UBC, and Toronto.

October 2025
Registration opens: September 2025
Students typically in Grades 11–12 (but open to younger students with advanced ability).
Students register through their schools or via CMS-authorized contest centres across Canada and abroad.
Top COMC scorers are often featured by Canadian universities for scholarships and research placements. For example, winners of the COMC have gone on to represent Canada at the International Mathematical Olympiad (IMO), bringing home medals and securing admission to elite math and engineering programs.
Universities like Waterloo, U of T, and McGill actively consider strong COMC results in their admissions and scholarship processes.
Work with us to build proof-writing skills, contest strategies, and a STEM-ready university portfolio.
