OUAC. Ontario high schools report midterm/final 4U/M grades
2027 entry
School deadline, not a student task. Universities receive these grades by November 26. Verbatim: "Deadline for the OUAC to receive all midterm or final grades available for 4U/M courses from Ontario high schools. Schools may report in-progress grades for full-year courses as soon as they are available." Universities receive these by the target date of November 26, 2026. This is a deadline on the high school, not on the student, but it governs which grades a university sees in the first round.

Full source wording

Verbatim: "There is no specific Undergraduate application deadline if you are a Group B applicant. Deadlines vary at each university and sometimes depend on the program. Visit the university websites or contact the universities directly for their deadlines. If you are interested in a program but the deadline has passed, you may contact the university's admission office for help. Be aware of university-specific deadlines for submitting transcripts and portfolios, if required, and for arranging interviews and auditions. You must ensure the OUAC has enough time to process your choices before the universities' program deadlines." OUAC defines Group B as anyone who does not meet the Group A criteria, e.g. not currently taking an Ontario high school course, a Canadian outside Ontario, an international applicant, a postsecondary transfer student, or a mature applicant.

Applicant pathways

Ontario degree entry

Ontario high-school GroupA applicants; degree-specific alternatives remain in the source block

Ontario High School (Group A)
Required Courses: English (ENG4U) Calculus and Vectors (MCV4U) Biology (SBI4U) Chemistry (SCH4U)
Recommended Course: Physics (SPH4U)
Admission Average Guideline: Mid to high 80s Averages reflect Ontario high school students. Achieving an average in the suggested range does not guarantee admission.

Required Ontario applicant steps

Ontario high school applicants

Report completed and in-progress Grade 11 U/M courses.

Ontario students taking IB

Ontario OSSD applicants taking IB; Western undergraduate admission

Western assesses Ontario students taking IB on their OSSD. Your guidance office converts predicted and final IB results to Ontario high-school grades and submits them through OUAC.
Use the Ontario course and supplementary requirements for your chosen program. IB credit assessment is separate from the admission decision.

Full IB Diploma subject requirements

Applicants assessed on the full IB Diploma curriculum; Medical Sciences entry

Biology, Chemistry and Mathematics (any IB mathematics), at Standard or Higher Level.

Ontario general credential route

Ontario secondary-school applicants; programme-specific subjects and supplements apply separately

Complete the OSSD and at least six Grade 12 U/M courses, excluding co-op, including ENG4U. Submit completed and in-progress Grade 11 U/M courses and required English-proficiency evidence when applicable.
Meet the chosen programme’s subject requirements. Required courses need at least 70%; recommended courses are distinct from required courses.

Credits and degree requirements

Programme: Recommended Course: Physics (SPH4U)
Before September of Year 2, complete at least 4.0 courses including the required biology, chemistry, mathematics and 1.0 Category A or B at the 1000 level. Pass the non-credit Medical Sciences 1000Y. The typical first-year load is 5.0 courses.
Earn at least 60% on the first attempt in each required biology, chemistry and mathematics half-course and at least 50% in other courses. Both 0.5 physics or computing requirements also need 60% on the first attempt and may be deferred to Year 2.
BMSc entry: Medical Sciences 2 students meeting the published conditions have assured entry to Year 3 BMSc. Other applicants use the competitive pool; first-year enrolment alone does not guarantee a particular module.
Medical Sciences 2 requires a full 5.0-course Fall/Winter load. Check module prerequisites when choosing courses.
Assured Year 3 BMSc entry requires the full Year 2 load, no Fall/Winter or summer failures, the listed module prerequisites with any first-attempt minimum marks, and an 80% average on the listed 2000-level module courses. If 3.5 or more are listed, the best 3.0 count.
Competitive-pool admission uses a 75% minimum across the applicable 2000-level courses or the best 3.0 if at least 3.5 are listed. Module prerequisites and capacity still apply.
The BMSc requires 20.0 credits, including at least 13.0 senior credits, 1.0 in each of Categories A, B and C, and 2.0 designated essay credits including at least 1.0 senior.
