Hosted by Youth Science Canada, the Canada-Wide Science Fair (CWSF) is Canada’s largest youth STEM event, bringing together the brightest young scientific minds from across the nation. Founded over 60 years ago, this annual celebration showcases nearly 400 finalists representing every province and territory, all competing for medals, scholarships, and prizes valued at nearly two million dollars.

More than just a competition, CWSF serves as a hub where innovation meets inspiration. The week-long event features project presentations, judging sessions, interactive experiences, and networking opportunities that forge lifelong connections between like-minded peers. From groundbreaking research to innovative solutions for real-world problems, the projects on display demonstrate the incredible potential of Canada’s youth.

CWSF culminates in public viewing days where thousands of visitors—including students, educators, and industry professionals—explore the Project Zone and engage with interactive exhibits at the STEM Expo. The event creates a unique convergence of education, industry, and community, proving that when young Canadians embrace their curiosity and transform questions into action, extraordinary discoveries follow.
