The 2025 Girls’ Math Team Canada was led by Kateryna Tretiakova (McMaster University) and Deputy Leader Courtney Allen (University of New Brunswick).

Courtney Allen expressed her admiration for the girls’ achievements:

“The girls worked hard just to get to the competition, and then accomplished something even greater by winning medals. I couldn’t be happier with the effort and dedication they showed.”

The team members also reflected on their experience at EGMO:

“I had an amazing time connecting with the other members of the Canadian team as well as with countries from across the world. Math is truly a universal language as we bonded over problem discussions, puzzle-solving, and card-playing. I’d like to thank the CMS for this exciting opportunity, as well as our leaders Kate and Courtney for their unwavering support throughout the journey.” – Honjar Xing

“I had an amazing experience at EGMO! I loved spending time with my team, meeting girls from other countries, and exploring the culture of Kosovo. The contest was challenging yet enjoyable, and it was inspiring to see this incredible community come together over a shared passion for math.” – Sophie Zhang

Supporting and celebrating girls in STEM is essential to building a more inclusive and innovative future. Opportunities like EGMO empower young women to showcase their talents on an international stage and help break down long-standing barriers in math and science. The CMS is proud to celebrate the accomplishments of Girls’ Math Team Canada and sincerely appreciates EGMO’s role in fostering an environment where girls can excel, grow, and inspire future generations to embrace math with confidence and enthusiasm.

The CMS gratefully acknowledges Jane Street for its generous support, which made Girls’ Math Team Canada’s participation in the European Girls’ Mathematical Olympiad possible.

The CMS also wishes to thank its members, partners, and donors, including the Samuel Beatty Fund, for their support of Girls’ Math Team Canada.

Congratulations, Girls’ Math Team Canada!

About the European Girls’ Mathematical Olympiad (EGMO)
The European Girls’ Mathematical Olympiad (EGMO) was created in 2012 and was first written in Cambridge, UK. It has since grown to include more than 50 countries. Participation in the EGMO is by invitation only. Each student competes individually to solve six questions, in a competition lasting two days, four and a half hours each day. The students were chosen largely based on the results of the 2024 Canadian Open Mathematics Challenge (COMC) written in October and a team selection test in January 2025.
