Closing the Gap – CMS Inclusion Initiative

CMS has vowed to reaffirm its commitment to a future for the mathematical community where the voices of Black and Indigenous mathematicians and STEM professionals are better reflected. As part of CMS Inclusion Initiative, the Society will invite 400 Black and Indigenous students to participate in the Canadian Open Mathematics Challenge (COMC) and the Canadian Mathematical Gray Jay Competition (CMGC) at no cost. This is an opportunity for students to engage with mathematics and STEM activities and have their mathematical talent recognized.

We invite all math teachers, school principals, and any other willing proctors to nominate students identifying as Black or Indigenous to take part in this competition.

Registration is now open for Canadian Mathematical Gray Jay Competition (CMGC). Registration for the Canadian Open Mathematics Challenge (COMC) will open in September 2021. You may nominate students to participate free of charge through the Closing the Gap program at any time throughout the year. CMS staff will keep your nomination on record and reach out to you in September.



Students who identify as Black or Indigenous; students must be Canadian citizens or Permanent Residents and must also fulfill the COMC-specific and the CMGC-specific eligibility criteria.

Application process

Before filling out the application form below, please make sure that you are nominating students who fulfill the Eligibility criteria.

Teachers or other adults who are willing to proctor students during the competition are asked to nominate their students by filling out the form below. Students who think they are eligible to take part in this initiative can nominate themselves; please note that students who nominate themselves require a proctor prior to filling out the form and must include the name, affiliation, and email address of the proctor in the nomination form. Accordingly, parents or guardians nominating their children have to ensure that the student has a proctor who will supervise them on the day of the competition.

Prizes and Awards

In addition to various Competition Awards and Prizes, Black and Indigenous students who take part in this initiative will automatically be entered in a draw to win one of four CMS’ $500 prize for their classroom to spend on math and STEM resources.

CMS Closing the Gap Webinar Series

Starting in 2020, the CMS offered free webinars to Black and Indigenous students and their educators and caregivers. Some of these webinars are preparatory courses for students taking part in the competitions, others discuss ways of engaging with mathematics that takes account of different knowledge systems, and some are aimed at educators and caregivers and discuss equity in mathematics and unconscious biases in education system.

The following webinars took place in 2020:
