Results Announced: 2026 Canadian Mathematical Olympiad & Junior Olympiad

 

Ottawa, ON – The Canadian Mathematical Society (CMS) is pleased to announce the results of the 2026 Canadian Mathematical Olympiad (CMO), Canada’s premier math contest. In its 58th edition, this year’s competition took place on March 12 with 95 participants. An additional 18 students competed in the Canadian Junior Mathematical Olympiad (CJMO). 

The CMO and CJMO are elite, invitation-based events. All official participants are Canadian citizens or permanent residents of Canada. Invitations were extended based primarily on student performance in the Canadian Open Mathematics Challenge (COMC) held in October 2025, and the CMO Qualifying Repêchage (CMOQR) held in February 2026.

“Year after year, the Canadian Mathematical Olympiad and Junior Olympiad (CMO/CJMO) highlight the astounding capabilities of our young mathematicians. Once again, the participants amazed us with their exceptional problem-solving skills and dedication. A standout moment this year was when a medalist submitted ingenious approaches to two problems, solutions that surprised the committee. Witnessing this level of creativity is a constant, thrilling reminder of why we host these events. A heartfelt congratulations to all our participants!”

Dr. Pawel Pralat (Toronto Metropolitan University), Chair of CMO Committee

Matthew Brennan Prize for Best Solution
The Matthew Brennan Prize honours the memory of IMO team leader and former Olympian Matthew Brennan. In collaboration with his family, the CMS awards this $500 prize to the author of the most elegant solution in the CMO.

This year, the Matthew Brennan Award goes to Perry Dai, for his solutions to Problem 2 and Problem 5. On Problem 2, he demonstrated a significantly better bound on the value D than anticipated. On Problem 5, he incorporated ideas from algebraic number theory towards proving the upper bound. Variants of these new approaches appear in the official solutions. Congratulations to Perry!

Sponsors & Supporters
The CMS sincerely thanks its exclusive CMO/CJMO sponsor, Citadel Securities, for making this competition possible and for supporting the next generation of mathematical talent in Canada.

The CMS is also grateful for the support, participation and cooperation of all its partners, members, individual donors, as well as parents, teachers, schools and school boards. 

About the Canadian Mathematical Olympiad and the Junior Olympiad
The Canadian Mathematical Olympiad (CMO) is Canada’s premier national advanced mathematics competition. Candidates require an invitation from the Canadian Mathematical Society to participate. The competition consists of five highly challenging questions requiring fully justified written solutions. The results of the CMO factor strongly in CMS’ selection process for the Canadian teams’ participation at international Olympiads.  Winning competitors from previous years are listed here.

The Canadian Junior Mathematical Olympiad (CJMO) is an advanced mathematics competition created for students up to grade 10. It is invitational and takes place at the same time as the CMO. The CJMO consists of five challenging questions designed for students up to grade 10. Each question requires a fully-justified written solution.

About the Matthew Brennan Prize for Best Solution
The Matthew Brennan Prize for Best Solution honours International Mathematical Olympiad (IMO) leader and former Olympian, Matthew Brennan, whose life was lost unexpectedly and before his time. The prize was created by the CMS in partnership with Matthew’s parents and awards 500 dollars to the participant with the best solution in the CMO.

Matt was born in Toronto and attended Upper Canada College from Grades one through twelve. In 2012, he started at MIT, where he obtained a Bachelor of Science in Electrical Engineering and Computer Science and in Mathematics in 2016, and a Master of Science in Electrical Engineering and Computer Science in 2018. His Master’s thesis, entitled “Reducibility and Computational Lower Bounds for Problems with Planted Sparse Structure”, was awarded the Ernst A. Guillemin Award for Best Thesis in Electrical Engineering. At the time of his death, Matt was in the final year of his Ph.D. in Electrical Engineering and Computer Science at MIT and had been awarded a Miller Fellowship at UC Berkeley starting in the fall of 2021. Matt’s main research interests were the theoretical aspects of machine learning and probability theory.

Matt represented Canada twice at the International Mathematical Olympiad, earning a bronze medal in 2011 and a gold medal in 2012. He returned to the IMO as deputy leader observer in 2014 and 2017, and was the leader in 2019. Matt was passionate about Olympiad math, and had served on the Canadian Mathematical Olympiad committee since 2014. He also contributed extensively to problem creation and selection. In addition to having had two problems included on the IMO shortlist, in any average year three of the five CMO problems were proposed by Matt. His dream in life was that after a long academic career, he would do contest problems all day as a professor emeritus.

When Matt was not doing research or Olympiad problems, he was likely playing basketball. In addition to spending hours and hours practicing and playing pick-up, he played on three different intramural teams. Even at the IMO training camps, he was constantly itching to play.

About the Canadian Mathematical Society (CMS)
