Canadian Open Mathematics Challenge (COMC)

The **Canadian Open Mathematics Challenge (COMC)** is a national mathematics contest organized by the Canadian Mathematical Society for secondary school students. It is typically written in early November and features challenging problems that test creative problem-solving, logical reasoning, and mathematical insight beyond the standard school curriculum. The contest is open primarily to high school students (and some advanced middle school students) in Canada, and is often written at schools under teacher supervision or through approved testing centers. Top-scoring students may be invited to participate in more advanced contests and selection stages leading toward the **Canadian Mathematical Olympiad (CMO)** and, ultimately, Canada’s team for the **International Mathematical Olympiad (IMO)**. Participating in COMC helps students deepen their mathematical understanding, build competition experience, and strengthen their academic profile for university applications.
