Contest overview
The Canadian Team Mathematics Contest (CTMC) is an exciting and challenging competition where participants work in teams to showcase their mathematical problem-solving skills through fun and engaging activities. A special feature of the CTMC is that schools can host the contest at their own school or be selected to participate at the University of Waterloo.

The CTMC consists of three events:

- Team event: Team members collaborate to solve a set of 25 problems (45 min).
- All questions in the Individual and Team events are short-answer.
- Relay event: Each team splits into two groups of three to solve questions where one participant's answer is needed by a teammate to solve the next question (45 min).
- There are no calculators allowed during the team event. Some calculators are permitted during the individual and relay events.
The difficulty level and content may vary. Junior participants can contribute, but teams without seniors students may struggle with challenging problems.
Below are links to three types of resources and classroom support that can help with preparation for the CTMC contest:
- Past Contests: Participants can review and attempt past contests to know more about the contest format, level of difficulty and to learn time management. The CEMC has published contests and their solutions from previous years in the Past Contests section of Tools and Resources.
- Math Courseware: Participants can use CEMC’s free, online Courseware to learn and review important curriculum content and concepts.
- CEMC Visits Schools: Experts from the CEMC are available to conduct problem-solving workshops for students and educators. Visit CEMC Visits Schools to learn more.
University of Waterloo-hosted event:
