About the OUAC

Located in Guelph, the Ontario Universities’ Application Centre (OUAC) processes applications for admission to the following programs at Ontario’s universities:

We are a not‑for‑profit, centralized application service for applicants to Ontario universities. We are a division of the Council of Ontario Universities (COU) and facilitate the process of applying to an Ontario university. Our activities are monitored by the OUAC Budget and Advisory Committee, which is appointed by COU.

We value equity, diversity and inclusion and believe that every person has a right to equal treatment. We are strengthened by diverse backgrounds, perspectives and experiences. We have equitable and accessible employment practices, based on the principles specified in Ontario legislation (Human Rights Code and Accessibility for Ontarians with Disabilities Act [AODA]).

Our Story

How It All Started

Before the OUAC, students applied directly to individual universities and replied to offers of admission as they received them. Inevitably, some universities had to cope with a surplus of registrations, while others suffered from “no shows”. In addition, students had to cope with an uncoordinated, multi-application environment.

A significant growth in the demand for postsecondary studies in Ontario prompted the desire to improve the enrollment management and planning process. Thus, with the provincial government’s encouragement and support, the OUAC was born.

Centralization of University Applications

Having a central location for all Ontario university applications and high school transcripts improved the ability to manage multiple acceptances of offers of admission, standardized data entry and helped to significantly reduce duplication and cost in processing multiple applications. A central location also made the application process easier for applicants by providing 1 place for them to go.

The benefits of a consolidated service were quickly realized and resulted in centralized admission processing for many of Ontario’s professional programs (e.g., medical school, teacher education programs, law school, and rehabilitation sciences programs).

Interesting Facts

  • For the 2022 application cycle, we received more than 857,000 applications from more than 201,000 individual applicants, compared to our first operating year, when we received 135,361 applications.
  • Between November 1996 and November 2023, the OUETS processed more than 4 million transcripts, of which nearly 3.4 million were processed completely electronically.
  • Before the OUAC had computers and data terminals on-site, punch cards were used to automate the undergraduate application process. An IBM key punch machine read the card, processed it and printed out a paper report.
  • In 2020, we mailed PIN letters for the 101 application directly to more than 700,000 Ontario high school students, due to the COVID-19 pandemic. In previous cycles, we bulk-mailed the letters to the high schools.
