The OUAC schedule for 2026–27 (entry September 2027), and the 184 Ontario programs that want more than your marks.

Where these come from. Every date is OUAC’s own: its 2026–27 counsellor schedule, its student key-dates page, which was brought up to date on September 14, 2026, and its start-up schedule for the application itself. Dates taken from those last two link to them. Last checked 2026-09-15. Check a date yourself before you rely on it, including ours.

OUAC now calls current Ontario high school applicants Group A (this used to be called 101). Group B is everyone else.

OUAC key dates

Half of these are deadlines for your school to file with the OUAC and half are the dates universities receive what was filed, about a week later. Each row says which. When do Ontario universities actually see your marks?

Deadlines by university

The OUAC calendar is the same for everyone. What differs is what each university prints on its own listings — a program that stays open to April 1, a supplementary due two weeks after OUAC closes, a scholarship that wants an application by December. One page per university, each date with its source.

Deadline reminders

Supplementary applications close before the January OUAC deadline, and some land in early December. We’ll email you before the ones that apply to you.

We send your email address and the programs you’ve starred, so the reminders are the right ones. Your marks and your average are never sent — they stay in this browser. Deadline emails only, a week before and the day before each date, and every one has a link to stop them.

Programs that need more than marks

An admission information form, a portfolio, an audition, a written questionnaire or a video interview. These almost always close before January 15, and missing one removes you from consideration no matter what your average is.

The flag below comes from each program’s own published admission criteria. The individual deadlines are set by the universities and move year to year — every row links to the program, and every program page links to the university’s own page. Do not take a date from us that you have not seen on their site. The full tracker, filterable by what each one asks for, is here.
