Six eligible 4U/M courses
At least four must be 4U or DU, all prerequisites are included, and no more than two eligible 4M courses can count.
McGill admissions
McGill admission requirements and program prerequisites vary by educational background. This guide answers the Ontario Top 6, Quebec R-score, Commerce, IB, CAPE, A-Level, GPA, SAT, deadline, and direct application questions applicants are searching for.
Reviewed August 25, 2026 · Previous cutoffs are not admission guarantees
Direct answer
McGill University does not use one admission average, GPA, or prerequisite list. Ontario applicants generally need an OSSD, at least six eligible Grade 12 U/M courses, 4U English or French, and every program prerequisite. Quebec applicants are reviewed using a pre-university DEC, overall R-score, and applicable core R-score. McGill separately evaluates IB, A-Level, CAPE, U.S., and other credentials.
McGill is in Montreal, Quebec—not Ontario—so undergraduate applicants apply directly to McGill rather than through OUAC. Previous lowest admitted grades are useful planning evidence, but McGill explicitly says they do not guarantee admission in a later cycle.

Ontario high school applicants need an OSSD before classes begin and at least six eligible Grade 12 courses. Four or more must be 4U or DU, including every prerequisite; up to two eligible 4M courses may complete the Top 6. All programs require 4U core English or French. English as a Second Language and French as a Second Language do not satisfy that core-language prerequisite.
Required mathematics and science courses normally must have been completed within the past five years. Most applied courses are excluded. McGill lists limited exceptions for specified Grade 12 technology courses, PSK4U, and 4M performing arts courses.
| Program or group | Ontario prerequisites | September 2025 lowest grades |
|---|---|---|
| Arts | 4U English or French | 90% Top 6; 88% language |
| Management (BCom) | 4U English or French, plus Calculus and Vectors | 93% Top 6; 90% mathematics |
| Biological, Biomedical and Life Sciences | 4U English or French, Calculus and Vectors, plus two of Biology, Chemistry, or Physics | 92% Top 6; 91% mathematics/science |
| Physical, Earth, Math and Computer Sciences | 4U English or French, Calculus and Vectors, plus two of Biology, Chemistry, or Physics | 91% Top 6; 89% mathematics/science |
| Civil Engineering | 4U English or French, Calculus and Vectors, Physics, and Chemistry | 91% Top 6; 90% mathematics/science |
| Electrical Engineering | 4U English or French, Calculus and Vectors, Physics, and Chemistry | 95.5% Top 6; 95% mathematics/science |
| Mechanical Engineering | 4U English or French, Calculus and Vectors, Physics, and Chemistry | 96% Top 6; 95% mathematics/science |
| Software Engineering | 4U English or French, Calculus and Vectors, Physics, and Chemistry | 90% Top 6; 90% mathematics/science |
These are the lowest grades McGill published for September 2025 admission—not Fall 2027 cutoffs, targets, or guarantees. The result can rise or fall with demand and space. Check the official table for the exact program, including Nursing, Architecture, Kinesiology, and other groups not condensed here.
For Ontario students, the Desautels Bachelor of Commerce requires 4U English or French and Calculus and Vectors. The September 2025 reference was a 93% Top 6 average and 90% in mathematics. For Quebec CEGEP applicants, McGill reported a previous minimum of 29.4 for both the overall and core mathematics R-scores, plus 26 in the core language score.
McGill's standard BCom is not on the current list of programs requiring extra supporting documents. Do not upload an unsolicited personal statement as a substitute for a requested item; follow the Applicant Portal checklist. Students comparing business programs can also use the Canadian business and commerce comparison.
Quebec applicants normally need a pre-university DEC before classes begin. McGill reviews the overall R-score and, where a program has prerequisites, a core R-score calculated from the required mathematics, science, or language courses. The university uses the overall R-score—not a program R-score—and can consider failures and repeated courses. Quebec Secondary V by itself is not a direct-entry credential.
| Program or group | September 2025 lowest R-score |
|---|---|
| Arts | 26.9 overall; 26 core language |
| Management (BCom) | 29.4 overall and core mathematics; 26 language |
| Biological, Biomedical and Life Sciences | 28 overall and core mathematics/science |
| Physical, Earth, Math and Computer Sciences | 28 overall and core mathematics/science |
| Architecture | 32.7 overall; 31.6 core mathematics/science |
| Mechanical Engineering | 33 overall and core mathematics/science |
These figures are McGill's September 2025 references and do not predict the next cycle. Check both the overall and core requirement for the exact program before interpreting an R-score.
McGill reviews the transcript plus predicted or final IB results. A complete diploma with at least 5 in each HL and SL subject is the minimum expectation, but competitive programs can require much more. Acceptable mathematics prerequisites are HL or SL Analysis and Approaches and HL Applications and Interpretation; SL Applications and Interpretation is not accepted when mathematics is required.
Advanced Level applicants generally need at least three A-Level-equivalent subjects and all program prerequisites. Caribbean applicants are reviewed using CSEC, CAPE Unit 1, CAPE Unit 2 predicted or final results, and school grades. Depending on faculty and courses, McGill may grant up to 30 advanced standing credits.
For Fall 2026, most undergraduate programs let U.S. high school applicants opt out of ACT or SAT consideration. McGill has not yet published the Fall 2027 test policy. Under the current policy, submitted SAT scores are generally competitive from 670 in Evidence-Based Reading and Writing and 580 in Math. Engineering and Architecture use 620 in Math. The ACT reference is 26 overall with section scores of at least 24. Program-specific grades and prerequisites still matter.
Applicants who do not meet McGill's English-language exemption rules must arrange an accepted proficiency result by the applicable document deadline. The international student guide covers language testing, study permits, and financial planning; the Caribbean pathways guide adds regional curriculum context.
As of July 29, 2026, McGill's official pages still show the September 2026 cycle. Fall 2027 deadlines have not been published. The dates below are expired planning references only; Music, Nursing, scholarships, financial aid, and other special cases can use different dates.

| Ontario high school | February 1, 2026 | May 4, 2026 | Mid-February to end of May 2026 |
| Quebec CEGEP | March 1, 2026 | April 15, 2026 | Late February to mid-May 2026 |
| Canadian high school outside Ontario and Quebec | February 1, 2026 | May 4, 2026 | Mid-January to mid-May 2026 |
| International Baccalaureate outside Canada and the U.S. | January 15, 2026 | March 1, 2026 | Varies by school system and file completion |
