The 2027 Ontario university application timeline

Start in summer by comparing programs and prerequisites. Once OUAC and the universities publish the new cycle, confirm program codes, applicant-group rules, fees, and every program-specific date.

Submitting through OUAC is only the first stage. Universities may send portal credentials and request transcripts, supplementary applications, portfolios, interviews, or language results on a different schedule.

  • August–September 2026: research programs and monitor the OUAC launch.
  • Fall 2026: build the application list and begin supplements, portfolios, and major-award work.
  • January 15, 2027: Group A completed-application deadline.
  • Winter–spring 2027: submit documents and monitor each university portal.
  • By May 28, 2027: latest Group A response date listed by OUAC.
  • June 1, 2027: earliest required offer response or financial commitment.

Group A vs Group B deadlines

Group A generally covers current Ontario high school applicants who meet OUAC's criteria. Group B includes applicants who do not meet every Group A criterion, such as many international, transfer, mature, and out-of-province applicants.

Group B does not have one universal OUAC deadline. The deadline comes from the university and program, which makes an individual tracker essential.

Deadlines that applicants commonly miss

The most expensive mistake is treating the OUAC date as the only date. A complete application may require several separate submissions, sometimes weeks apart.

  • Supplementary essays, activity profiles, video interviews, auditions, or portfolios.
  • Official transcripts, predicted grades, translations, and language-test results.
  • Major entrance awards, need-based aid profiles, and faculty scholarships.
  • Residence applications, deposits, accessibility requests, and meal-plan choices.
  • Study-permit and proof-of-funds steps for international students.

Build a deadline tracker that actually works

Create one row for every university-program choice and separate columns for the OUAC submission, portal activation, documents, supplement, scholarship, residence, offer conditions, and response. Save the official source link beside each date and record when you last verified it.

Set reminders at least two weeks before every hard deadline. Portals, payment systems, references, and document uploads can take longer than expected.

Frequently asked questions

Quick answers to the questions applicants ask most often.

When is the Ontario university application deadline for 2027?

For Ontario high school applicants in Group A, OUAC lists January 15, 2027 as the deadline to submit a completed undergraduate application. Group B and program-specific deadlines can differ, so every applicant must also check the university and program pages.

When do Ontario university applications open for 2027?

OUAC's 2026–2027 guidance schedule says Ontario Universities' Info and updated application material begin appearing in August 2026. The Undergraduate application is expected to launch in September, but applicants should confirm the live date directly with OUAC.

Can I apply after the OUAC deadline?

OUAC can continue processing applications received after the Group A deadline, but each university decides whether a program remains open and whether a late application will be considered. Competitive programs can close at or before their stated deadline.

When will Ontario universities send offers for 2027?

Offers can arrive throughout the cycle. OUAC lists May 28, 2027 as the latest date Ontario universities should respond to Group A applicants who applied by the January deadline, once the required information is available.

When do I have to accept an Ontario university offer?

OUAC lists June 1, 2027 as the earliest date an Ontario high school applicant may be required to accept an offer or make a financial commitment such as a registration or residence deposit. Read the conditions and dates in your actual offer.

Are scholarship and residence deadlines the same as the application deadline?

Not necessarily. Major awards, supplementary applications, portfolios, interviews, transcripts, language tests, and residence applications can each have separate deadlines. Track them as individual tasks rather than relying on one OUAC date.
