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.

No single OUAC deadline
University, program, transcript, portfolio, interview, and audition dates still apply

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.

Computer Science admission-category restrictions

St. George Computer Science category applicants

Applicants with prior postsecondary study at U of T or another institution cannot apply directly to the Computer Science admission category or programme. Consult the separate transfer-student route.
The published exceptions include secondary students taking dual-enrolment courses listed explicitly on their secondary transcript, and previous programmes/certificates not eligible for transfer credit. Further documentation may be requested. Dual-enrolment courses do not receive transfer credit for students admitted to this category/programme.
Offers to this St. George admission category cannot be deferred.
The optional alternate admission category is selected in JOIN after OUAC. It does not affect first-choice consideration or guarantee alternate admission; Computer Science and Rotman cannot be selected as alternates.

Progression after first year in CMP1

Current St. George students in the Computer Science admission category

Complete 4.0 credits within 12 months of entering CMP1. Earn at least 70% in CSC110Y1 and 77% in CSC111H1, and complete the approved calculus sequence for guaranteed entry to the CS Specialist or Major.
Request the program in ACORN during the first program request period. The current Specialist calendar lists MAT148H1 or MAT158H1 followed by MAT149H1 or MAT159H1, or MAT137Y1 or MAT157Y1 where applicable.
For the CS Minor, the CSC111H1 minimum is 70%. The guarantee has no calculus requirement for the Minor.

Progression from other Arts & Science categories

Current St. George Arts & Science students outside the CMP1 guarantee

The CS Major and Minor have competitive entry. The CS Specialist is reserved for CMP1 students who meet the guarantee.
For the Major or Minor, complete 4.0 credits and earn at least 70% in each of CSC148H1 and either CSC165H1 or CSC240H1 at St. George. Selection also considers the supplemental application.
Request the program in ACORN during the first request period and submit the program supplement. The 70% marks are eligibility floors.

General full-IB credential route

Full IB Diploma applicants; campus/faculty subject and supplemental rules remain separate

Present the full IB Diploma, including English at HL or SL. Other programme prerequisites must be at senior/Grade 12 equivalent level. Individual IB courses can support admission only with another recognized secondary-school diploma.

Degree requirements

Bachelor of Computer ScienceSeptember 2027 entry
