Canada Jay Mathematical Competition (CJMC)

Canada Jay Mathematical Competition (CJMC) is a new Canadian math competition open to students in grades K-8, with questions based primarily on grade 5-8 curriculum. This competition has been created by mathematicians from across Canada.

The problems are meant to be a fun fall activity for students and teachers to complement their math curriculum and build students’ problem solving skills. The CJMC offers engaging problems that allow for discussion after the competition and get students excited about math. The competition will have 15 questions which take place over 90 minutes. It will consist of 3 blocks of 5 questions with an increasing level of difficulty from beginning to end.

CMS is committed to contributing to a more inclusive environment in the mathematical community. Funding will be made available for students who identify as Black or Indigenous to participate in the 2022 CJMC free of charge. For more information, please visit the CMS Inclusion Initiative page.

The 2022 CJMC will be held on Thursday, November 17, 2022 in North and South America and on November 18, 2022 in the rest of the world.

2021 Competition

The 2021 CJMC was held on Thursday, November 18 in North and South America. The contest was held on November 19th in the rest of the world. 

All official marks, awards and certificates for the 2021 Canada Jay Mathematical Competition (CJMC) have now been released. See the Results section on this page for details.

Here is the 2021 Question Booklet so you can review it with your students and teachers. You can find the official solutions here.

Online Proctoring Instructions


The Canada Jay online platform is browser-based. 
The supervising proctor and each student will require a tablet or a laptop/desktop computer.

Orientation Video

We have created a detailed orientation video to show you how proctors prepare and perform an in-person session with their students in a classroom.  If you are proctoring remotely (via the internet), then it is your responsibility to maintain suitable monitoring of your student during the exam (this is typically with Zoom or similar product) – CMS cannot assist you in that.

Access Keys and Codes

Teachers get the Access Keys and Codes for themselves and their students through the Teacher Portal (where you ordered your exams).  If you are a lead teacher with several proctors, you will want to collect your school’s Keys and Codes and divide them up for your proctors, as you see in the video.

The Keys and Codes will be available on your teacher portal by Thursday Nov 11th.

Rules and Eligibility

The CJMC is based on the grade 5-8 curriculum, but is open to students in all locations, at all grade levels.

The contest can be written at any of the following locations:

  • school
  • library
  • tutoring centre
  • home school

In order to participate, students need to be registered by a proctor (teacher, librarian, tutoring centre, or a home school teacher).

By signing up for the CJMC you agree to the following rules:

  • An adult (teacher, librarian or another adult) must be present to supervise the competition;
  • Once started, students have 90 consecutive minutes to complete the test;
  • Calculators are not permitted. We recommend using scrap paper and a pencil when figuring out answers;
  • Students are to write the test individually, with no outside help
    (i.e. from other students, parents, teachers, cheat sheets, textbooks, the Internet etc.).

We count on the proctors and participants to ensure that these rules are followed.

Official Participants

To be an official participant and qualify for awards, the following additional requirements must be met:

  1. The student must be in grade 8 or below during the 2021/22 school year and
  2. The student must be attending school full-time either virtually or in person (elementary, secondary, or home-schooled) at least since Sept 15, 2021 and
  3. No mobile phones, calculators or other electronic devices are permitted. Students writing the exam “online” may use a computer or tablet only to access the exam, and an electronic device such as a cell phone may be used for supervision of a student writing remotely. Other uses of such devices are prohibited.
  4. The student must either be supervised in a school or location that the CMS has approved as an Official Competition Writing Centre* (OCWC),  or must be supervised remotely for the entirety of the exam by a proctor from a registered OCWC or a certified teacher under the ministry of education.
  5. The 90 minute writing period must begin and end sometime between 8 AM and 8PM (08:00-20:00) local time
    1. on Thursday, November 18th, for schools in North America, South America, Central America or in time zones covering these areas
    2. on Friday, November 19th, elsewhere in the world.

* Once a school signs up for an account, it is assessed to see if it qualifies as an Official Competition Writing Center (OCWC). If your school is a permanent, full-time, complete curriculum school with a well-established physical location, it will likely qualify.

Prizes and Awards

Only official participants, as defined above, are eligible for awards.

There are two divisions: the Canadian Division, which is only for participants writing the exam from within Canada (or Canadian citizens or permanent residents writing outside Canada); and the International Division, which is only for non-Canadian participants writing the competition outside of Canada.

The awards in the Canadian Division are based on best in Canada, best in province, best in region, and best in each grade (best in grade 8, best in grade 7, etc.). The top official participants from outside of Canada (and who are not Canadian citizens or Permanent Residents) are considered for the International Division awards, which are not grade-dependent or region-dependent.

Awards are not offered where participation rates are very low or where scores are below the cutoff scores. All participants will be awarded a participation certificate.



  • The top score in a division receives Gold.


  • The second highest score in a division receives Silver.


  • The third highest score in a division receives Bronze.

** IF there is a tie score for gold, silver and bronze, multiple people are awarded.

Honorable Mentions

  • The fourth, fifth and sixth highest scores in a division are given an Honorable Mention with all tying students listed equally. 
  • Please note: This list of honorees is alphabetical, not listed by order of score.


  • Certificates list the awards earned in any/all divisions
  • If the student did not earn Gold/Silver/Bronze/HM in any division at all, the student gets: (a) a Performance with Distinction certificate if in the top quartile, (b) a Performance with Honors certificate if in the second quartile, (c) or a Participation certificate

About the Canada Jay:

In North America, official scientific, English, and French bird names are adjudicated by a dedicated committee of what is now known as the American Ornithological Society or “AOS” (and before 2016 as the American Ornithologists’ Union or “AOU”). “Canada Jay,” restored as the official English name in 2018, goes back to at least the early 1800s. In fact, by using “Gray Jay’ in its 1957 checklist, the AOU needlessly violated one of its own stated naming principles, namely that “traditional vernacular names should be retained whenever possible.” When a group of mostly Canadian ornithologists pointed out this error in late 2017 and proposed that “Canada Jay” be restored as the official name, the AOS graciously agreed and formally announced the restoration, a few months later, in July 2018.

–  Dan Strickland, world expert on the Canada Jay

On November 16, 2016, at their College of Fellows Annual Dinner in the Canadian War Museum, the Royal Canadian Geographical Society (RCGS) stunned many Canadians (and some folks elsewhere in the world, too!) by choosing the third-place Canada Jay over the first-place Common Loon as their candidate to be Canada’s national bird. But you could not find a more Canadian bird. First, as a member of the corvid family (crows, ravens, magpies and jays), it is one of the smartest birds on the planet. Its brain-to-body ratio is equivalent to that of the chimpanzee and dolphin and nearly rivals that of the human. Second, the Canada Jay is extremely tough and hardy. By not leaving the country in winter, it has adapted itself to not only surviving our harsh Canadian winters but breeding then as well. This bird is known to incubate its eggs at -30 Celsius! Third, Canada Jays are extremely friendly, readily coming down to perch on open hands, even without food, and on ski poles, cameras and spotting scopes, without any training whatsoever. Fourth, unlike many songbirds in the world, Canada Jays are not promiscuous and the mates do not cheat on each other. The pair remains together year-round, often flying together everywhere and even perching side by side, touching each other. So, we’ve got “smart,” “hardy,” “friendly” and “loyal.” What better way to describe the typical Canadian, eh?
