2023 Application Deadlines for Ontario High School Students

January 12, 2023

Deadline for Ontario high school students to submit their completed application to the OUAC.

Note: The OUAC still processes applications received after this date and distributes them to the universities; however, specific university deadlines will apply.

The initial application includes all final grades from completed Grade 11 and 12 courses and a list of all current-year courses in progress.

May 29, 2023

The latest date all high school applicants who submitted their application by the January application deadline can expect a response from an Ontario university. 

This includes:

  • an offer of admission
  • a refusal or
  • a deferral, once additional information is received.

June 1, 2023

The earliest date an Ontario high school student may be required to respond to an Ontario university offer of admission and give a financial commitment (e.g., registration deposit, residence deposit, etc.).

All other admission-related elements are considered part of the offer of admission, including:

  • scholarships,
  • other forms of student assistance or financial incentives and
  • offers of residence.

Therefore, a student may accept these other offers before June 1, 2023, but Ontario universities will not compel a student in any way to make a decision earlier than this date.
