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.
Check the current 2027 OUAC guide for the full Group A criteria.
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.
