OUAC Info & Updates

Ontario Universities’ Application Centre (OUAC) Information

What is OUAC?

“OUAC” stands for Ontario Universities’ Application Centre.

What does OUAC do?

The OUAC is an application processing centre for undergraduate admissions to Ontario Universities. The OUAC receives student applications, processes them and transfers the information to the universities. The OUAC does not make admission decisions; that is the universities’ responsibility.

Will my marks be sent directly to OUAC?

For students applying through OUAC as a 101 applicant, you will first need to add “Ontario Virtual School” within the Academic Background section of your OUAC account to allow our administration access to your application. Once you have added us, simply check off “101” when requesting your report card and we will update your mark directly to OUAC for you. For students applying to university as a 105, simply provide the university’s admissions email as well as your student ID number.

How do I access my OUAC account?

You can access your OUAC account by following this link to the OUAC login page.

This blog will help you through the application process.

Can I use OUAC to apply to universities outside of Ontario?

The OUAC only collects and updates marks for students applying to at least ONE university within Ontario. However, the OUAC will also assist the following out-of-province universities with collecting academic data for Ontario high school students who have applied to at least one Ontario university through the OUAC:

  • Acadia University
  • Bishop’s University
  • The University of British Columbia
  • University of Calgary
  • Concordia University
  • Dalhousie University
  • McGill University
  • Saint Mary’s University
  • Simon Fraser University
  • The University of Victoria

Students who apply to these out-of-province universities can authorize the universities to request their academic information from the OUAC. To authorize them, the applicant must include their 11-digit OUAC Reference Number on the university’s application form, where the 11th digit is always “0”. NOTE: If you do not intend to apply to any universities within Ontario, you would simply apply through your selected schools directly. Once your application has been processed and a student number issued to you, please contact [email protected]lschool.ca to have your OVS documents forwarded.
