We empower Canadian youth to transform their questions into innovations and discoveries through STEM projects. We envision a Canada where every young person, regardless of background, location, or resources, has the chance to explore their curiosity and realize their potential. We’re building the future problem-solvers and innovators Canada needs.
The Power of a STEM Project
When youth investigate questions they care about, they discover they’re capable of original thinking, solving real problems, and contributing meaningful ideas to the world.
For over 60 years, Youth Science Canada has created the ecosystem that makes these transformations possible: connecting students with resources, opportunities, and peers, from their first spark of curiosity through to representing Canada on international stages.
Last year alone:
10,000+ students presented STEM projects at regional STEM fairs across Canada
400 top young scientists competed at the Canada-Wide Science Fair
60 students represented Canada at prestigious international STEM competitions
92% of students expressed an increased interest in STEM careers as a result of their participation
From Kitchen Table to World Stage
It Starts Locally
Students explore questions they’re passionate about and present their findings at one of 98 regional STEM fairs across every province and territory. These community celebrations give young people their first experience being taken seriously as researchers.
Top Students Advance to National Competition
Selected regional participants are invited to the Canada-Wide Science Fair – a week-long celebration where 400 of Canada’s brightest young minds showcase their projects, compete for over $1.3 million in scholarships and awards, and form connections that often last a lifetime.
Excellence Goes Global
Outstanding CWSF participants represent Canada at international competitions including ISEF, EUCYS, and MILSET events, gaining global perspectives and demonstrating Canadian innovation on the world stage.
“As a Grade 13 student, I participated in the city science fair in Toronto and then went on to represent my region at the Canada-Wide Science Fair. It was an experience that would ultimately define my life.”
“Science fair was a life-changing experience that really made me realize, if I set my mind to something, anything is possible. It was an exciting moment for a 15-year-old.”

“The main goal is not winning awards but to make the world a better place. With our more sustainable, natural and vegetarian protein, dietary fibre and oils, we are addressing some of the world’s largest food supply challenges.”

Getting Started Is Simpler Than You Think
For Students
Start by exploring what genuinely interests you! We provide free resources through mySTEMspace to guide you from idea to presentation.
For Parents
Your child doesn’t need to be a genius or have access to specialized equipment. The best STEM projects come from genuine curiosity about everyday observations.
For Educators
STEM projects align perfectly with inquiry-based learning. Our Smarter Science program offers professional development and classroom resources that make project-based learning accessible and effective.
