When Does OUAC Open for 2025?

The OUAC portal typically opens in late September of the year before your intended university start date. That means for Fall 2026, the OUAC 2025 application opening will be in late September 2025.

Applying early doesn’t guarantee admission, but it does give you more time to complete requirements and ensures you won’t be rushing to meet mid-year deadlines. Students planning to fast-track OSSD credits or upgrade grades should align their course timelines with OUAC’s opening to avoid last-minute stress. At OES, you can enroll in courses anytime and gain access within 24 hours, making it easier to start upgrading or finishing credits right when you need them.

Understanding OUAC Applications

OUAC is the central application hub for all Ontario universities. It processes applications and forwards them to universities,  but admission decisions are made by the universities themselves. Applicants are divided into two categories, known as 101 (also called Group A) and 105 (also called Group B).

OUAC 101 vs 105 Applicants (Group A vs Group B)

• 101 applicants (Group A): Current Ontario secondary school students applying directly from day school.
• 105 applicants (Group B): Everyone else—adult learners, international students, out-of-province students, homeschoolers, and those whose primary studies are through private or online schools such as OES. Students who are still enrolled in an Ontario day school full-time remain 101 applicants, even if they take extra or upgrade courses at OES.

OUAC 2025 Key Dates and Deadlines

The OUAC calendar is filled with milestones students must follow carefully. Below are the university application deadlines in Ontario for 2025 students can’t afford to miss.

Equal Consideration Deadline (January 15, 2025)

January 15 is the most critical date. All Ontario universities guarantee equal consideration for programs if applications are submitted by this deadline. Programs in engineering, business, and health sciences often close after this point, so students who miss it may lose access to competitive choices.

Students finishing OES courses should schedule their final assessments well in advance of January 15 to ensure grades are uploaded.

Late Application Deadlines 2025–2026

Some Ontario university programs remain open for applications beyond January 15, with certain deadlines extending into the spring or even summer. This happens because not all programs fill up by the equal consideration date. Competitive programs often close right after January 15, but larger or less selective programs may keep accepting applications until their spaces are full. These OUAC late application deadlines 2025–2026 vary by university and program, so students should always confirm directly with the school. OES’s fast-track courses can be especially valuable in this situation, helping students complete missing credits quickly so they can still apply to programs that remain open.

Offers of Admission and Response Deadlines

Most Ontario universities issue admission offers by late May. The standardized response deadline is June 1, meaning students must accept one offer through OUAC by that date. Some schools release offers earlier in the cycle, particularly for strong applicants or less competitive programs.

It’s also possible to receive an admission offer after May, especially if a program still has unfilled spaces or if students become eligible once their final grades are submitted. This can happen in programs with rolling admissions or when universities adjust enrollment targets in late spring or early summer.

To avoid complications, students should ensure their final grades are reported to OUAC before May. Missing or incomplete marks can delay or even jeopardize an admission offer. At OES, final marks are uploaded directly to OUAC, helping students stay confident their applications are complete and visible to universities at the right time.
