Canadian Senior and Intermediate
Mathematics Contests

The Canadian Senior and Intermediate Mathematics Contests (CSMC and CIMC) are two contests designed to give students the opportunity to have fun and to develop their mathematical problem solving ability.

Visit our Coronavirus Information webpage for more details on the impact of COVID-19 on CEMC contests, workshops and resources.


Students in Grades 10 or 9 or below (CIMC) and Grades 12 or 11 and CÉGEP students (CSMC); motivated students in lower grades are also encouraged to write these contests.

Mathematical Content

Most of the CIMC problems are based on the mathematical curriculum up to and including Grade 10. Most of the CSMC problems are based on the mathematical curriculum up to and including the final year of secondary school.

Contest Registration Information

Schools can register for contests online by the deadline. View fees.

Schools that have not registered for previous contests are encouraged to participate, and can start by filling out a New School Application form.

Contest Preparation

We recommend that students spend some time preparing for our contests by trying to solve problems. Our Grade 12 open courseware provides a way to brush up on material. Many teachers use past contests in the classroom.

Results and Recognition

The results booklet and averages and award cutoffs are posted online.
Teachers will be able to access their students' results and generate certificates.

We will recognize top-performing students and schools.
