Canadian Team Mathematics Contest

Collage of students participating in Canadian Team Mathematics Contest

The Canadian Team Mathematics Contest (CTMC) is a fun and challenging team competition.


Teams of 6 secondary school students in any combination of grades. At least half of the problems in the Individual Event, and many problems in the Team Event, are accessible to students in grade 9 or 10.


The official contest is scheduled to take place on Thursday, April 7, 2022. See official date for the current year. Teams may participate unofficially in school-organized events on or after after Friday, April 8, 2022. Contest questions and full solutions are posted online in mid June.


  • team questions, where team members may collaborate (45 min)
  • individual problems (45 min)
  • math relays — one student's answer to a question is needed by a teammate to solve the next question (45 min)

There are no calculators allowed during the Team event. Some calculators permitted during the Individual and Relay events. More information for the supervising teacher is available.

Please note that the CTMC is currently only available in English.

Contest Preparation

We recommend that students spend some time preparing for our contests by trying to solve problems. Many teachers use past contests in the classroom.


Coaches may use our system to generate certificates for participants.
