Frequently Answered Questions About OUAC 101
1. Is OUAC 101 only for Ontario high school students?
Yes. OUAC 101 is specifically designed for students currently enrolled full-time in an Ontario high school and working toward their Ontario Secondary School Diploma (OSSD). If you’re completing Grade 12 and haven’t previously attended any post-secondary institution, this stream is meant for you. A real-world example would be a student at a Toronto public school using their school-issued PIN and Ontario Education Number to log in to OUAC and apply to three Ontario universities in one go.
2. Is OUAC only for Ontario universities?
Yes. OUAC,the Ontario Universities’ Application Centre,manages applications exclusively for public universities within Ontario. That means you can apply to schools like the University of Toronto, Western University, and McMaster through one centralized platform. If you’re looking to apply outside of Ontario, such as to UBC or McGill, you’ll need to use each university’s individual application system.
3. Do all universities have the same deadlines on OUAC?
No, and this is important to understand. While the general deadline is usually around mid-January, highly competitive programs,like Engineering at Waterloo or Rotman Commerce at UofT,may have earlier deadlines for supplementary forms or documents. For example, a student applying to Queen’s Commerce learned too late that a separate PSE (Personal Statement of Experience) had an earlier due date. Always verify each university’s program deadlines on their official site.
4. Do I need to submit transcripts manually for OUAC 101?
Not usually. If you’re a current full-time Ontario high school student, your grades are automatically sent by your school to OUAC. However, if you’re part of a special program like IB or taking private credits outside your main school, you might be asked to upload documents separately. One Mississauga student completing an online English course had to scan and submit final grades via email as requested by the university.
5. Is there a fee waiver option for OUAC 101 applicants?
Yes. Financial help is available, but it’s not automatic. Speak to your school’s guidance counselor about your circumstances. They can submit a request on your behalf to the OUAC or your school board. A student from a low-income household in Brampton successfully received a waiver for the base application fee after providing a simple letter from their counselor outlining financial need.
