When Windsor decides, and what happens after
In Windsor’s own words to guidance counsellors, from the OUAC resource guide (September 2026 entry). That guide was written for last cycle, so a line carrying a specific 2025 or 2026 date is marked — the pattern holds, the date does not.
- Deferring your offer
We consider requests for deferrals for most non-limited enrollment programs. https://ask.uwindsor.ca/app/answers/detail/a_id/534/ kw/undergraduatedeferral Students must satisfy all conditions of their original offer to be considered. A deferral may not exceed 1 academic year.
- Tuition deposit
$2,000 tuition deposit for all undergraduate international applicants. Deposits are due June 1, 2026.last cycle’s date
OUAC dates that apply to everyone
The 2026–27 (entry September 2027) schedule from OUAC’s counsellor site, checked 2026-08-20. The source. The dates you act on yourself; the school-to-OUAC and OUAC-to-university transmission dates are on the full calendar.
- August 2026youThe OUAC relaunches Ontario Universities' Info and starts posting application material for fall 2027 admission. This is the month the information appears, not the month you can apply.
- Mid-September 2026not published by OUACyouThe OUAC application opens for Ontario high school students. OUAC has not published an exact date for this cycle — anything you see online naming a specific day is not coming from OUAC.
- January 15, 2027youThe deadline for Ontario high school students to submit their completed application. This is the one date everybody knows — but several supplementary applications land before it. The OUAC still processes applications received after this date, though individual university deadlines then apply.
- May 28, 2027youThe latest date you can expect a response if you applied by January 15 — an offer, a refusal, or a deferral of admission.
- June 1, 2027youThe earliest date a university can require you to respond to an offer or pay a deposit. Scholarships, financial aid and residence all count as part of the offer: you may accept them earlier if you want to, but nothing can be demanded of you before this date.
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, and you can reply to stop them.
