The Canadian Mathematical Olympiad (CMO), is, as the name suggests, the national mathematical Olympiad of Canada. It is run by the Canadian Mathematical Society and sponsored by the company Sun Life Financial.[1] The Olympiad plays several roles in Canadian mathematics competitions, most notably being Canada's main team selection process for the International Mathematical Olympiad.[2]

Approximately 70 to 80 people qualify for and write the CMO each year.
Qualification for the CMO is usually through the Canadian Open Mathematics Challenge, though only "official" participants of that contest can enter. Generally, the cutoff for the CMO on that contest is in the 70s.[3]
The contest is three hours long. There are 5 questions on the CMO, each worth 7 marks, for a total of 35 points. Each problem is graded the same way as it is on the IMO.
From 1969 to 1972, the CMO was 10 questions long. In 1973, this was shortened to 7 questions. It alternated between 7 and 8 before finally stabilizing to five questions in 1979.
Two graders will grade the questions. If there is a dispute between the graders by more than one point, they will reconsider the problem until a consensus was reached.
The grading is considered as follows:
