Converting a Canadian percentage grade to a 4.0 GPA scale is strictly non-linear. Under the standard Ontario Medical School Application Service (OMSAS) table: 90%–100% = 4.00 (A+), 85%–89% = 3.90 (A), 80%–84% = 3.70 (A-), 77%–79% = 3.30 (B+), and 73%–76% = 3.00 (B). Never use a linear formula like (Percentage / 100) × 4; doing so artificially suppresses an 85% Canadian average from an official 3.90 down to an inaccurate 3.40.

1. Official OMSAS 4.0 Scale Conversion Table
The Ontario Medical School Application Service (OMSAS) undergraduate grading table is the de facto benchmark utilized by universities, graduate programs, and law schools across Canada to convert percentage transcripts into standardized 4.0 Grade Point Averages:
| Percentage Range | Letter Grade | OMSAS 4.0 GPA | BC / Alberta 4.33 Scale | Academic Standing |
|---|---|---|---|---|
| 90.0% – 100% | A+ | 4.00 | 4.33 | Exceptional / Distinction |
| 85.0% – 89.9% | A | 3.90 | 4.00 | Excellent |
| 80.0% – 84.9% | A- | 3.70 | 3.70 | Very Good |
| 77.0% – 79.9% | B+ | 3.30 | 3.30 | Good |
| 73.0% – 76.9% | B | 3.00 | 3.00 | Satisfactory |
| 70.0% – 72.9% | B- | 2.70 | 2.70 | Adequate |
| 67.0% – 69.9% | C+ | 2.30 | 2.30 | Marginal |
| 63.0% – 66.9% | C | 2.00 | 2.00 | Pass |
| 60.0% – 62.9% | C- | 1.70 | 1.70 | Lowest Passing Grade |
| 50.0% – 59.9% | D / D+ | 1.00 – 1.30 | 1.00 – 1.33 | Conditional Pass |
| 0.0% – 49.9% | F | 0.00 | 0.00 | Fail |
2. Why the Linear Percentage Formula Is Flawed
Online forums and generic calculator sites frequently instruct students to multiply their percentage grade by 0.04 (e.g. Percentage / 25). In Canadian higher education, this math is completely invalid:
If you score an 85% in a Canadian university course:
- Flawed Linear Formula:
85 × 0.04 = 3.40 GPA(B+ equivalent). - Official OMSAS / Canadian Scale: 85% is a solid A grade, which converts to 3.90 GPA.
A linear formula artificially strips 0.50 Grade Points from your academic record, transforming a competitive medical or law school candidate into an uncompetitive applicant.
3. Provincial Scale Variations (UBC, McGill, U of T)
Canadian education falls under provincial rather than federal jurisdiction. As a result, universities in British Columbia, Quebec, and Ontario apply different local transcript grading policies:
Uses a stepped 4.0 scale. An 85%–100% translates to 4.00, while 80%–84% is an A- (3.70). Most medical and professional schools in Ontario convert all transcripts using the OMSAS uniform matrix.
UBC and Simon Fraser University utilize a 4.33 maximum GPA scale. An A+ (90%–100%) earns a 4.33, while an A (85%–89%) earns a 4.00. SFU transcripts display both letter grades and percentage equivalents.
McGill applies a 4.0 maximum scale where 85%–100% = 4.0 (A), 80%–84% = 3.7 (A-), and 75%–79% = 3.3 (B+). There is no numerical 4.33 tier on McGill degree transcripts.
4. How Course Credit Weights Impact Cumulative GPA (cGPA)
You cannot simply average your course GPAs together. In Canadian universities, courses are weighted according to their credit unit value:
- Half-Year Courses (0.5 FCE / 3 Credits): Standard one-term semester courses.
- Full-Year Courses (1.0 FCE / 6 Credits): Full-year two-term courses (e.g., Organic Chemistry or Year-Long Theses), which carry double the weighting of a half-course.
Cumulative GPA = Total Grade Points / Total Weight Units
5. Step-by-Step Worked cGPA Calculation Example
Consider an Ontario undergraduate student with a mixed semester courseload:
| Course Name | Percentage Score | OMSAS GPA | Credit Weight | Grade Points |
|---|---|---|---|---|
| Biology 101 | 86.0% (A) | 3.90 | 0.5 FCE | 1.95 |
| Chemistry 102 (Full Year) | 81.0% (A-) | 3.70 | 1.0 FCE | 3.70 |
| Calculus 100 | 92.0% (A+) | 4.00 | 0.5 FCE | 2.00 |
| English Literature | 74.0% (B) | 3.00 | 0.5 FCE | 1.50 |
Total Grade Points = 1.95 + 3.70 + 2.00 + 1.50 = 9.15
Total Credit Weights = 0.5 + 1.0 + 0.5 + 0.5 = 2.5 FCE
Cumulative GPA = 9.15 / 2.5 = 3.66 OMSAS GPA
6. Canadian Graduate & Medical School Benchmarks
When applying to competitive graduate programs across Canada, understand these published admissions cutoffs:
- Ontario Medical Schools (U of T, McMaster, Western, Ottawa): Competitive median accepted applicants typically present an OMSAS cGPA of 3.85 to 3.92. Minimum thresholds require at least 3.60.
- Canadian Law Schools (Osgoode, U of T Law, UBC Allard): Competitive median accepted GPA is generally 3.75 to 3.88 on a 4.0 scale alongside a 160+ LSAT score.
- Standard Graduate School (MSc / MA): The universal minimum baseline for Master's admission across Canadian universities is a mid-B average (75% or 3.00 GPA) across your final two years of study (last 60 credits).

What is considered a good GPA in Canadian universities?
A GPA between 3.30 and 3.69 (B+ to A-) is considered a solid, above-average standing in Canadian universities, qualifying students for most Master's degree programs and Dean's Honours Lists. A GPA of 3.80 or higher (A to A+) is exceptional and competitive for medical school, top law schools, and doctoral funding.
Does an A+ count as 4.0 or 4.33 in Canada?
It depends on your province and institution. In British Columbia and Alberta (such as UBC, SFU, and U of A), an A+ earns 4.33 on a 4.33 scale. In Ontario (such as U of T and Waterloo) and Quebec (McGill), the scale caps at 4.00, meaning both A and A+ receive a maximum of 4.00 (or 3.90 for A and 4.00 for A+ under OMSAS).
What is an 80% average in a Canadian university?
An 80% average is classified as an A- in Canadian university grading conventions, which converts to a 3.70 GPA under the official OMSAS conversion framework. This grade comfortably satisfies the academic requirement for honors designations at graduation.
How does WES (World Education Services) evaluate Canadian degrees?
World Education Services (WES) evaluates Canadian 4-year honours bachelor's degrees as equivalent to a 4-year US Bachelor of Science or Bachelor of Arts. WES applies course-by-course letter grade evaluations based on institutional grading scales rather than dividing percentage scores by 25.
Can failed courses (F) be removed from a Canadian GPA calculation?
In most Canadian universities, if you retake a failed course, both the original F (0.00 GPA) and the new passing grade remain permanently visible on your official academic transcript. However, some universities replace the 0.00 with the new grade when calculating your internal graduation cGPA. In contrast, OMSAS averages all attempts including failed grades.
