About the Ottawa Regional Science Fair

The Ottawa Regional Science Fair is organized and run by a volunteer organization to encourage students in the Ottawa-Carleton Region, from grades 7 to 12, to research, develop, and present projects in the fields of science and engineering. Students from both public and private schools in the region are invited to enter projects in the fair.

Each year, approximately 200 projects are entered and judged in the Junior (grades 7 and 8), Intermediate (grades 9 and 10), senior (grades 11 and 12), and special awards categories. The awards and prizes include cash awards and scholarships. Participation in the Fair also ensures the students’ eligibility to compete for a position on the team representing the Ottawa-Carleton Region at the subsequent national competition, the Canada Wide Science Fair (CWSF)

We award over $25,000 worth in prizes, including 11 all expenses paid trips to compete at the Canada-Wide Science Fair.

Many schools hold their own school science fairs where they select their participants for the ORSF. If your school does not hold its own fair you may register for the ORSF directly.
