A message – to Finalists & Delegates

We are pleased and proud to welcome you to the 62nd annual Canada-Wide Science Fair in Ottawa, Ontario! 450 of Canada’s top young scientists from grades 7 to 12 and Cégep will have the honour of representing their region at this exciting event, with the opportunity to win awards, prizes and scholarships that may very well shape their futures. Beyond showcasing their projects, students will:

  • SHARE a week with other Canadian students who are also interested in STEM;
  • MEET new friends from across Canada;
  • INTERACT with scientists, engineers and other STEM professionals;
  • WELCOME visitors in the Project Zone including 10,000 visiting students and teachers;
  • ENCOURAGE others to build upon their curiosity about STEM, and inspire the pursuit of scientific and technological solutions to the challenges that face the world;
  • CELEBRATE at our ceremonies and special events, DANCE their hearts out, EXPERIENCE cultural activities and some of the world-class attractions unique to this region.

We’re building upon the CWSF tradition of excellence to create an exciting week-long event for participants and delegates alike. Meanwhile, we wish all finalists an abundance of inspiration and dedication as projects are prepared for regional fairs across Canada with the ultimate goal of being selected for the Canada-Wide Science Fair. Good luck! Hope to see you in Ottawa, Ontario in May of 2024!
