What Is Canada-Wide Science Fair (CWSF)?
Canada-Wide Science Fair brings selected regional finalists together to present original STEM projects, meet peers and compete for awards. The 2027 fair takes place May 29-June 5 at the Hamilton Convention Centre and McMaster University.
Students begin with the affiliated regional fair covering their home or school address. If neither area has a fair, a virtual or nearest-region alternative may be available at the organizer’s discretion. National entry follows regional selection; there is no single student application deadline. Confirm current fees, travel coverage and any family contribution with the regional coordinator rather than treating historical 2026 costs as a 2027 quote.
