加拿大数学公开赛(Canadian Open Mathematics Challenge) 是加拿大首屈一指的全国数学竞赛，其为加拿大奥数国家队Canadian Mathematical Olympiad (CMO)首轮选拔赛。旨在鼓励学生探索、发现和学习更多关于数学和解决问题的知识。主办方加拿大数学学会的核心宗旨是促进数学研究，帮助改进加拿大中小学的数学教学，鼓励支持数学和数学教育的发展。
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.
