Ottawa Regional Science Fair

About The Fair

The Ottawa Regional Science Fair (ORSF) is a volunteer-driven, non-profit organization that encourages students in grades 7 to 12 from public and private schools in the Ottawa-Carleton area to engage in science and engineering projects. Annually, around 200 projects are showcased, divided into Junior (grades 7-8), Intermediate (grades 9-10), Senior (grades 11-12), and special awards categories. Participants can win cash awards, scholarships, and qualify for the Canada Wide Science Fair (CWSF).

ORSF distributes over $25,000 in prizes each year, including up to 11 fully funded trips to the CWSF. Many schools host their own science fairs to select participants, but students can also register directly if their school does not hold a fair. This allows all interested students the opportunity to present their innovative projects and contribute to the scientific community.
