Next deadline
OUAC. Ontario high schools report midterm/final 4U/M grades
2027 entry
School deadline, not a student task. Universities receive these grades by November 26. Verbatim: "Deadline for the OUAC to receive all midterm or final grades available for 4U/M courses from Ontario high schools. Schools may report in-progress grades for full-year courses as soon as they are available." Universities receive these by the target date of November 26, 2026. This is a deadline on the high school, not on the student, but it governs which grades a university sees in the first round.
Other deadline details
No single OUAC deadline, deadlines are set by each university and sometimes by programOUAC Undergraduate application, applicants who are not Ontario high school students (Group B)2026 entry
- No single OUAC deadline, deadlines are set by each university and sometimes by program
- No single OUAC deadline
- University, program, transcript, portfolio, interview, and audition dates still apply
Full source wording
Verbatim: "There is no specific Undergraduate application deadline if you are a Group B applicant. Deadlines vary at each university and sometimes depend on the program. Visit the university websites or contact the universities directly for their deadlines. If you are interested in a program but the deadline has passed, you may contact the university's admission office for help. Be aware of university-specific deadlines for submitting transcripts and portfolios, if required, and for arranging interviews and auditions. You must ensure the OUAC has enough time to process your choices before the universities' program deadlines." OUAC defines Group B as anyone who does not meet the Group A criteria, e.g. not currently taking an Ontario high school course, a Canadian outside Ontario, an international applicant, a postsecondary transfer student, or a mature applicant.
