| Quick Answer: If you missed the January 15, 2026 OUAC deadline or did not receive an offer by May 28, 2026, you are not out of options. Starting June 3, 2026, the OUAC Admission Information Service (AIS) lists every Ontario university program that still has open spots for fall 2026. Lakehead University is the most flexible, with most domestic programs extended until August 31, 2026. You need a minimum 60% average and must be on track to complete your OSSD with six 4U/M courses by August 2026. Competitive programs like Nursing or Engineering are typically closed by June. |
Key Highlights of What Universities Accept Late Applications in Ontario After June 2026
- The AIS opens June 3, 2026 and shows real-time open spots at all Ontario universities
- Lakehead University accepts most domestic applications until August 31, 2026
- Laurentian University keeps most undergraduate programs open after the June cycle
- You need a minimum 60% average and near-complete OSSD to qualify for AIS access
- Winter and spring intakes exist at Nipissing, Brock, Carleton, TMU, and Trent
- Upgrading one 4U credit course at USCA Academy can raise your average enough to qualify
If you are reading this after June 1, 2026, you are not out of options. Several Ontario universities accept late applications every year, and the official OUAC Admission Information Service opens on June 3, 2026 specifically to connect students with open spots. This guide tells you exactly which universities keep accepting applications, how to use the AIS, what your minimum requirements are, and the fastest backup paths if fall 2026 is not possible.
Here is the part most students do not hear: missing the January 15 OUAC deadline or not receiving an offer by May 28 is more common than you think. According to the Ontario Universities’ Application Centre (OUAC), the AIS has helped thousands of students find placements in the weeks after the main cycle closes. The window is narrow, but it is real.
Why Do Some Universities Accept Late Applications in Ontario?
Ontario has 22 universities. After the main application cycle closes in late May, many programs still have unfilled seats. Universities do not want empty classrooms, so they list available spots through the AIS. This happens every year.
Programs with more space tend to be in arts, general sciences, social sciences, and education. Competitive programs like Nursing, Computer Science at Waterloo, or Commerce at Queen’s are typically full by April. Late applicants have the best chance in programs with broader admission averages.
If you already have a conditional offer and are worried about your final grades dropping, read our guide on Ontario university conditional offer requirements to understand exactly what happens next.
| Important: The June 3, 2026 AIS opening does not mean all universities are open. It means you can log into the AIS and check which programs at which universities still have space. Programs close as seats fill. Act fast. |
The Admission Information Service (AIS): Your Primary Tool After June 2026
The AIS is a free tool run by the Ontario Universities’ Application Centre (OUAC). It opens June 3, 2026 and stays active through mid-August. Here is what you need to know before you use it.
Who Can Use the AIS
- You are a current or recent Ontario high school student
- You are working toward or have completed the OSSD with six 4U/M courses
- You will have your OSSD complete by August 2026
- You have a minimum average of 60% (higher averages are usually needed for most programs)
If you are an international student or came from outside Ontario, contact each university directly instead of relying solely on the AIS. See our international school in Ontario guide for specific pathways available to non-domestic students.
How to Use the AIS in 5 Steps
- Go to ouac.on.ca and log into your OUAC account
- Click the AIS link from the undergraduate application dashboard
- Search by program, subject area, or university to see what is open
- When you find an open program you want, add it to your application
- Submit your application and watch your email for a response from the university
Responses from universities through the AIS typically come within 1 to 3 weeks. Some come faster. Do not wait until August to start your search. If you have never used the OUAC portal before, our step-by-step OUAC 101 guide walks you through logging in, navigating the dashboard, and submitting applications.
Which Ontario Universities Accept Late Applications After June 2026?
Here is a breakdown based on official OUAC 2026 key dates and each university’s published policies. Status changes as seats fill, so always verify directly on the university website.
| University | Late Application Policy | Domestic Deadline | International? |
| Lakehead University | Most programs open pending space. Three intakes: Fall, Winter, Spring/Summer. | Aug 31, 2026 (Extended) | Yes, March 1 extended |
| Laurentian University | Most undergraduate programs open after main cycle. Education programs (TEAS) also open. | Open until further notice | Contact admissions |
| Nipissing University | Winter and spring admission available. Course selection is limited. Email registrar first. | Contact registrar | Contact admissions |
| Brock University | Late applicants considered if prerequisites complete. Winter/spring via internal form. | Varies by program | Limited |
| Algoma University | Winter and spring admission available. Course offerings restricted. | Varies | Contact admissions |
| Carleton University | Several Arts & Social Sciences and Public Affairs programs open for winter/summer. | Varies by program | Limited |
| Toronto Metropolitan University (TMU) | Select programs open for winter/spring if prerequisites are complete. | Varies by program | Limited |
| Trent University | Accepts winter applications for several programs. Contact registrar for deadlines. | Contact university | Contact admissions |
| University of Ottawa | Some programs available for spring/summer. University may close programs at any time. | Program dependent | Yes, check program page |
| McMaster University | Spring/summer only if OSSD is complete. Final grades due April 1 (spring), May 15 (summer). | Spring/Summer only | Very limited |
| University of Toronto (UTM) | Uses AIS for open programs. Check UTM open programs page directly. | Via AIS | Limited |
| York University | Participates in AIS. Limited seats post-June. Check program availability. | Via AIS | Limited |
Bottom line: Based on Lakehead’s published deadline page, most domestic programs stay open until August 31, 2026, giving you the longest window of any Ontario university. If you have a completed or near-complete OSSD, Lakehead is your most realistic option for a September 2026 start.
What Happens If You Did Not Get an Offer by May 28, 2026?
May 28, 2026 was the OUAC target date for all Group A applicants to receive a response. If you received a refusal, got no offers, or had a conditional offer revoked, here are your three main paths.
Path 1: Use the AIS to Find Open Spots (June 3 Onwards)
This is your fastest route to a September 2026 start. Log into your OUAC account from June 3 and search the AIS. Programs fill quickly, so do this in the first week of June. If you are not sure how to track your application status after submitting, our OUAC application status guide explains how to monitor updates in real time.
Path 2: Upgrade Your Marks and Reapply Next Cycle
If your average was below what competitive programs required, upgrading one or two courses can make a significant difference. A student who moves from 72% to 80% opens up many more program options in the next OUAC cycle starting October 2026.
USCA Academy offers individual OSSD credit courses with flexible start dates and small class sizes of 5 to 15 students. You can upgrade ENG4U, MHF4U, SCH4U, or any 4U course, and your grades get submitted directly to OUAC for the next cycle. Learn about OSSD programs at USCA Academy.
Path 3: Consider Winter or Spring Intake at Ontario Universities
Several universities including Nipissing, Brock, Carleton, and Algoma accept students for January 2027 (winter) or May 2027 (spring) entry. This is not a defeat. It is a strategic delay that gives you time to upgrade marks and arrive with a stronger profile. According to the OUAC winter and spring admission guide, Carleton, TMU, and Trent have specific program lists available for non-September entry. Contact their registrar offices directly with your transcript.
A Word for International Students Who Missed the Deadline
If you are an international student applying through OUAC 105 and missed your program’s deadline, your situation is different from domestic applicants.
- Group B (international) deadlines vary by university and program. Some programs had March 1, 2026 as the extended deadline for international applicants at Lakehead.
- You cannot typically access the AIS if you are applying from outside Ontario. Contact each university’s international admissions office directly.
- As of January 1, 2026, most international students need a Provincial Attestation Letter (PAL) with their study permit application. Check the Ontario government’s international student page for current PAL requirements.
- USCA Academy is a DLI-registered school. International students enrolled at USCA can apply for a Canadian study permit while completing their OSSD. This online-to-campus pathway is specifically designed for students whose visa was rejected or who need more time before university. Explore USCA’s international student programs to understand your options.
If your visa was rejected or you need more time to meet prerequisites, starting at USCA Academy online and transferring to campus has helped many students from over 25 countries get on track. With five intake periods per year, you are never waiting 12 months for the next opportunity.
How to Strengthen Your Late Application: 4 Things That Actually Work
1. Get Your Final Transcript Ready Immediately
Universities reviewing late applications through the AIS move fast. Have your official transcript or interim grades ready before you start searching. Your current school, or USCA Academy if you completed courses there, can send grades directly to OUAC electronically.
2. Contact Admissions Offices Directly
Do not rely only on the AIS. Call or email the admissions offices at universities where you found open programs. Introduce yourself, confirm space availability, and ask if there is anything you can do to strengthen your application. This proactive step sets you apart from passive applicants.
3. Be Flexible With Your Program Choice
If your first-choice program is full, check related programs in the same faculty. A student who wants Business can consider Economics or Sociology, complete first year with a strong GPA, then apply internally to transfer. Many Ontario universities allow internal transfers after first year. Avoid the common errors students make at this stage by reviewing our guide on common OUAC application mistakes before you submit anything late.
4. Use a Credit Course to Boost Your Average Before August
If your average is at 68% and an open program prefers 75%, completing one additional credit course can change your outcome. USCA Academy’s individual credit courses can be completed in 4 to 8 weeks. Your updated grade gets submitted to OUAC before universities finalize their late admission decisions.

What About OSSD Credit Upgrading While Applying Late?
If your grades are the reason you did not receive an offer or your conditional offer was revoked, upgrading a credit course is the most direct solution. Here is what the process looks like at USCA Academy.
- USCA Academy is Ontario Ministry of Education inspected and recognized by all Ontario universities
- Class sizes range from 5 to 15 students so you get individual attention on every concept
- Credit courses can be started at any point in the year, not just in September
- Completed grades go directly to OUAC so universities see your updated marks in real time
- USCA’s university counsellors assist with OUAC documentation and ensure your transcript reaches the right place on time
Students at USCA Academy have been accepted to the University of Toronto (including a CAD $100,000 President’s Scholarship recipient), University of Waterloo, McMaster, Queen’s, Western, and more. The school’s 99% university acceptance rate reflects a consistent track record of students successfully navigating Ontario admissions. Once you have your grades upgraded, read our guide on what to do after accepting your Ontario university offer so you are ready for every step that follows.
Conclusion: What You Should Do Today
If you are reading this in June 2026 and do not have a university offer, the AIS opening on June 3 is your first move. Log into your OUAC account on June 3 or as close to that date as possible. Search for open programs. Add the ones that fit your academic profile and submit your application the same day.
If your grades are the problem, use this time to upgrade a course. USCA Academy’s credit courses can be completed in 4 to 8 weeks with your marks submitted directly to OUAC. An updated transcript in late June or July can still influence a late admission decision.
And if September 2026 is not possible, a winter 2027 start or a fresh fall 2027 application with stronger marks is not a failure. It is a smarter path than starting underprepared in a program you do not want.
USCA Academy has guided students from missed deadlines to University of Toronto and Waterloo acceptances. Our university counsellors know the Ontario admissions system and can help you build a plan that works for your specific situation.

Frequently Asked Questions
1. Can I apply to Ontario universities after the June 2026 deadline?
Yes, but your options are more limited. Starting June 3, 2026, the OUAC Admission Information Service (AIS) lists Ontario university programs that still have spots available. Most open programs are in arts, sciences, and social sciences. Competitive programs in nursing, engineering, or commerce are usually closed by this point.
To use the AIS you need to be on track for OSSD completion with six 4U/M courses and a minimum 60% average, though most programs require higher.
2. What is the AIS and how is it different from the regular OUAC application?
The regular OUAC application is used before the January 15 deadline to apply for equal consideration. The Admission Information Service (AIS) is a separate tool that opens in early June and shows which programs at Ontario universities still have open seats after the main cycle.
You use the AIS to add programs directly to your existing OUAC application. It is specifically for students who did not receive an offer or whose offer was not accepted.
3. Which Ontario university is the most flexible for late applicants in 2026?
Based on official data, Lakehead University is the most flexible for late applicants. Most programs remain open for domestic applicants until August 31, 2026, pending space availability. Lakehead has three intake periods each year: Fall (September), Winter (January), and Spring/Summer (May/July).
Programs in education at Lakehead (codes A10, A30, A32) are also listed as open until further notice through the OUAC TEAS application.
4. What if my Ontario university conditional offer was revoked?
If your conditional offer was revoked because your final grades dropped below the stated requirement, you have three options. First, check the AIS from June 3 for open programs at other universities. Second, contact the university admissions office to explain your situation.
Some universities will consider a letter of explanation, especially if your grade drop was minor. Third, upgrade the course through an accredited school like USCA Academy and reapply in the October 2026 cycle. Read our full guide on Ontario university conditional offers to understand your rights and next steps.
5. Can international students use the AIS?
The AIS is primarily designed for Ontario high school students completing the OSSD. International applicants (Group B) typically cannot access AIS in the same way. If you are an international student who missed the deadline, contact each university’s international admissions office directly. Some universities like Lakehead had extended deadlines for international applicants to March 1, 2026. The Ontario government’s university page has current study permit and PAL guidance for international students.
6. Is it worth starting at a university in a program I did not want just to get in?
That depends on your goal. Many Ontario universities allow internal transfers after first year if you maintain a competitive GPA, often 75% or above. If your target program is Business or Psychology, starting in a related first-year program and applying internally is a real and relatively common path. However, if the program difference is large, such as trying to move from General Arts to Nursing, that transfer is usually not possible. Talk to a counsellor before committing.
7. What is USCA Academy’s role in helping students in this situation?
USCA Academy is an Ontario Ministry-inspected private school in Mississauga that offers individual OSSD credit courses, university preparation programs, and full OSSD completion. Students who need to upgrade grades, complete missing credits, or finish their OSSD can enroll at any time during the year. With five intake periods annually and class sizes of 5 to 15 students, USCA Academy is specifically designed for students navigating non-standard timelines.
