Pascal, Cayley and Fermat Mathematics Contests

The Pascal, Cayley and Fermat Contests are an opportunity for students to have fun and to develop their mathematical problem solving ability.


Students in Grade 9 or below are eligible to write the Pascal Contest.
Students in Grade 10 or below are eligible to write the Cayley Contest.
Students in Grade 11 or below are eligible to write the Fermat Contest.


Written in February. See details for current year.


The contest is written by individuals in schools. More information for the supervising teachers is available.

Mathematical Content

Early questions require only concepts found in the curriculum common to all provinces. The last few questions are designed to test ingenuity and insight. Rather than testing content, most of the contest problems test logical thinking and mathematical problem solving.

Contest Registration Information

Register for contests through our website 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. Many teachers use past contests in the classroom and the CEMC problem set generator allows anyone to create random sets of problems with the option to customize the topics covered.

Results and Recognition

Results booklets (Pascal, Cayley, Fermat) and averages and cutoffs are online.
Teachers can access their students' results and generate certificates.

We recognize top-performing students and schools.
