Eligibility and Registration Inquiries

Yes. The CJMC is a competition that is open to any student with an interest in and grasp of mathematics. 

All registrations for the CJMC must come from schools, through teachers or proctors. Individual students (and their parents) may ask any nearby school if they are participating in the CJMC and if they are willing to add an exam in order to have the student participate at the school on exam day.

The CMS may have writing centres across Canada at our partner universities for students who are unable to write the exam at their own school. We will also have online writing centres for those students who cannot participate through a school. 

For more information, please see our CJMC Eligibility Page. 

Typically, registrations for the CJMC come from schools or an official competition writing centre (OCWC), through teachers or proctors.

Individual students (and their parents) may ask any nearby school if they are participating in the CJMC and if they are willing to add an exam in order to have the student participate at the school on exam day. 

The CMS has some limited space at writing centres across Canada run by our partner universities. Look for the "Student Self Registration" option on the CJMC home page to register for this.

There are no grade eligibility requirements for the CJMC. However, the competition is aimed at grades 5-8. Any grade can write the competition but students in grades 9 and above are considered unofficial. Students in grades 8 and below are official if all other eligibility criteria are met.

Teachers use their account on the Teacher's Portal to place an order for exams; payment can be online or sent to us via cheque. Teachers may choose from the online format, or the paper format. Paper exams are either couriered to the school, or emailed as a PDF to be printed locally. Online exams are taken directly online using a computer. 

Students whose schools are not participating, or who do not attend a conventional school may choose to register and pay as individuals using the Student Self-Registration method. 

Registration can be completed by visiting the CJMC 2022 page and selecting from our registration options. 

For schools in Canada, the online version has a minimum of 3 exams, and the paper option has a minimum of 5.

For schools outside of Canada, the online version has a minimum of 5 exams, and the paper option has a minimum of 10. 

Yes, tutoring centres and home school teachers can sign up students if schools are not participating. Please keep in mind that a certified teacher who is not related to the student will need to be arranged. Parents can proctor students, but students would be considered unofficial in this case. 

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 for the entirety of the exam by a proctor from a registered OCWC or a certified teacher under the ministry of education.


1. Printed exams shipped to you: Deadline for registration is Monday November 3rd, at 11:59 PM EST.  Orders that are not paid at that time may be changed at CMS discretion to digital delivery instead of print shipments. Schools not verified as official writing centers will also be changed to digital delivery.
2. Digital delivery of print exams: Deadline for registration is Sunday Nov 13th at 11:59pm EST.  Exams and other material is sent as PDF to teacher's email. The exams must be printed locally at the school. Orders that are not paid by that time may be cancelled at CMS discretion. Exams will be emailed on Tuesday, November 15th and/or Wednesday, November 16th.
3. Online exams:  Deadline for registration is
Sunday Nov 13th at 11:59pm EST. Access codes and URLs are shared with teachers through teacher portals by Tuesday Nov 15th. Teachers proctor their remote students online as they work.


A small number of spots are available for Canadian students whose schools are not participating in the CJMC. Students can register and pay as individuals and be proctored by our university writing partners for official participation. 

Deadline for registration is Sunday Nov 13th at 11:59pm EST, but space is likely to run out before that. Registrations are not complete until marked paid on our system.

Please see the CJMC Eligibility page.

Modes of writing the 2022 CJMC

Printed exams are delivered to the school or the writing centre by courier, or may be sent electronically for printing at the school (digital delivery). The answer pages are then returned by courier.

Teachers may order online exams to be written on computers in the classroom which saves costs on paper exams.

Please see our instructional video to understand the online procedure and see what the students will be working with. Please note: the video uses the former name of the Canada Jay Mathematical Competition (The Canadian Mathematical Gray Jay Competition). 

Online CJMC

If writing the competition online, it must be written on Thursday November 17th during the school day for students in Canada and the Americas, and on Friday November 18th for students in other parts of the world.

Due to Covid-19, it may not be possible for students to write the exam at school. In this case, teachers may arrange for students to write remotely, provided that both teachers and students have access to an electronic device. 

CMS has created a new platform to host the CJMC online competition. Students can complete the CJMC on our platform in the classroom or from home while being observed by a certified teacher from an official competition writing centre (OCWC).  In the absence of such supervision, the students would be unofficial and not eligible for awards.

The CJMC online platform is browser-based. As a teacher or supervising proctor you will require access to a tablet or a laptop/desktop computer.

To access the online exam, you will need Access Keys and Codes for yourself and your students. These will be available in 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.

For 2022, the Keys and Codes will be available on your teacher portal by Tuesday, November 15th.

Please watch our detailed orientation video to show you how proctors prepare and perform an in-person session with their students in a classroom. This video refers to the CJMC under its old name, The Canadian Mathematical Grey Jay Competition, but still contains relevant information about the proctoring process. 

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 with that.

Before the exam, your teacher or proctor will contact you with access codes to write the exam in our online platform.

If you are writing remotely, your teacher or proctor should also share a Zoom link or other equivalent proctoring software. You must write the exam under appropriate supervision to be considered official.

If you used the Student Self-Registration you will be proctored by one of our university-based writing centres. We will email you the URL for the online competition, the Zoom link for your proctor, and your access keys on Monday or Tuesday before the exam. If you don't have it by Tuesday, check your Spam folder and if you still can't find it, email us at or phone us at (613) 733-2662, ext. 710.

Yes. Feel free to adjust this as you see appropriate. Do not send them the Sitting Code - give that to them during your zoom session instead.

Dear {{Student name}},

Your 2022 CJMC “Student Key” is {{StudentKey}}.

You will need this on Thursday, November 17th starting at {{12pm}}, when we will be writing the Canada Jay Mathematics Competition.  It’s a 90 minute multiple-choice test written online while I proctor you through Zoom.  

Please connect online to the Zoom no later than {{11:45am}} so we can all go over the rules and get connected to the exam.  The Zoom link is [xxxxxxx]

You'll want to have scrap paper or a notebook to do your calculations.  Remember that the use of phones or calculators is not permitted at any point during the exam.
