One application, two applicant groups

Group A and Group B do not share one deadline

Group A

Group A applicants must meet every OUAC rule for current Ontario high-school students. The application assigns the group.

Confirm the Fall 2027 rules after OUAC publishes the new guide.

The confirmed completed-application deadline is January 15, 2027.

Group B

Applicants outside Group A are Group B.

This includes many international, transfer, mature, and out-of-province applicants.

Group B has no single deadline. Use each university and program page. Allow time for OUAC processing.

The public now uses Group A and Group B, not 101 and 105. See the current OUAC 101 vs 105 explanation when older sources use those labels.
