Urgent Notice: If your school cancels its science fair due to the education labour conflict, we encourage you to register for the ORSF directly.

Why Should You?

If you’re in grades 7-12, we want you to use your curiosity and creativity to make the world a better place through STEM.

Think about the challenges facing Canada and the world: Discovery, Energy, Environment, Health, Information, Innovation, and Resources. Start with whatever you love (there’s STEM in everything); use the skills you’re good at, and do something you care about.

Canadian scientists, engineers, innovators, entrepreneurs – and even astronauts – say that their science project and science fair experience changed their lives. Where will your project take you?

How to Register?

First, read the ORSF rules and check the important dates.

Registration must be completed online at www.orsf.ca. The signature form and entry fee must be received no later than March 21, 2020.

There is a $30 registration fee per student (projects with two participants pay $60). This fee helps offset administrative costs of the fair. Payment is to be made by a cheque to be included with the registration entry form or through Interac e-transfer payment.

Please make cheques payable to the Ottawa Regional Science Fair.

All paper registration forms and cheques should be mailed to:

Ottawa Regional Science Fair



K1G 3H7

Please submit Interac e-transfer payment for the registration fee of $30 PER STUDENT to registration@orsf.ca; please note the name of the students for which payment is being submitted in the memo/note field. The password for the e-transfer should be sent to registration@orsf.ca, along with a scanned copy (PDF format) of the entire signed registration form.

No refunds will be issued for no-shows, late, or disqualified participants.
