Canadian universities use a 4.0 GPA scale that shares similarities with the American system but has important regional differences. Understanding how your GPA is calculated — and how it varies across provinces and institutions — is essential for academic planning, whether you're aiming for graduate school, professional programs like law or medicine, or competitive scholarships like NSERC and SSHRC.
Canadian GPA calculations vary more between institutions than most students realize. A 3.7 at one university isn't the same as a 3.7 at another — always verify the specific scale and conversion used by the programs you're applying to.
The Canadian GPA System
Most Canadian universities use a letter grade system that maps to a 4.0 scale. Unlike the US where this scale is nearly universal, Canadian institutions show significant variation. Some Quebec universities use a different system entirely. Always verify your institution's specific grading policy.
| Letter Grade | Grade Points |
|---|---|
| A+ / A | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C- | 1.7 |
| D+ | 1.3 |
| D | 1.0 |
| F | 0.0 |
How Canadian GPA Is Calculated
The GPA formula in Canada follows the same credit-weighted approach used in the US. Each letter grade converts to a grade point value, which is multiplied by the course's credit weight (typically 3 or 6 credits for a half or full-year course). These products are summed across all courses and divided by total credits attempted.
GPA Formula
GPA = Σ(Grade Points × Credits) ÷ Σ(Credits)
For example, if you earn an A (4.0) in a 3-credit course and a B+ (3.3) in a 6-credit course, your GPA would be: (4.0 × 3 + 3.3 × 6) ÷ 9 = 3.53. The 6-credit course has twice the impact, reflecting the greater workload.
Percentage-to-GPA Conversion in Canada
Many Canadian universities — particularly in Ontario — grade using percentages, which must be converted to the 4.0 scale. These ranges vary by institution — UBC, McGill, and Ontario universities each use slightly different cutoffs.
| Percentage | Letter Grade | Grade Points |
|---|---|---|
| 90–100% | A+ | 4.0 |
| 85–89% | A | 4.0 |
| 80–84% | A- | 3.7 |
| 77–79% | B+ | 3.3 |
| 73–76% | B | 3.0 |
| 70–72% | B- | 2.7 |
| 67–69% | C+ | 2.3 |
| 63–66% | C | 2.0 |
| 60–62% | C- | 1.7 |
| 57–59% | D+ | 1.3 |
| 53–56% | D | 1.0 |
| 50–52% | D- | 0.7 |
| Below 50% | F | 0.0 |
University-Specific Differences
Canadian universities don't follow a single national standard, which creates important differences students should understand.
There is no unified grading system across Canadian universities. An 80% at one school may convert to a 3.7 while it's a 3.9 at another. Always verify your institution's specific scale before using any GPA calculator, and double-check the conversion tables used by the program you're applying to.
Ontario universities generally use a 4.0 scale with percentage grades, and OMSAS (Ontario Medical Application Service) has its own GPA conversion table for medical school applications. McGill University uses a 4.0 scale but with unique percentage bands and class averages that can make direct comparison with other schools difficult. UBC primarily uses percentage grades, and their GPA is calculated differently from Ontario schools. Universities in Quebec outside McGill may use the R-score (cote de rendement) system, which factors in the strength of the student body. When applying to programs outside your university, always provide your transcript with the grading scale.
OMSAS GPA: A Special Conversion
If you're applying to Ontario medical schools, your grades go through OMSAS (Ontario Medical Application Service), which uses its own GPA conversion — and it's stricter than most university scales.
OMSAS converts each course grade individually using a standardized table, then calculates a weighted average. Key differences from your university GPA: an A+ may count as 4.0 (same as A at most schools), but the percentage cutoffs for each letter grade can differ from your university's scale. OMSAS also breaks down your GPA into subcategories — cGPA (cumulative), wGPA (weighted, which drops your lowest credits from your fullest year), and 2-year GPA (last two years only). Western Ontario's wGPA calculation can significantly help students who had a rough first year. Understanding which GPA variant each medical school prioritizes lets you focus your applications strategically.
Western Ontario's medical school uses a weighted GPA that drops your lowest credits from your fullest academic year. If you had a weak first year but improved dramatically, Western's wGPA could be significantly higher than your cumulative — potentially the difference between getting an interview and being screened out.
B2 and L2 GPA: Your Second Chance
Some Canadian programs — especially law schools — use Best Two Years (B2) or Last Two Years (L2) GPA calculations instead of (or alongside) your cumulative GPA. B2 takes your two academic years with the highest GPAs, while L2 uses your most recent two years.
This matters enormously for students who struggled early but improved. If your first-year GPA was 2.8 but your third and fourth year GPAs were 3.8, your B2 GPA would be 3.8 — a full point higher than your cumulative. Schools that use B2/L2 include several top Canadian law schools and some graduate programs. Research which calculation each program you're applying to uses, and target your application strategy accordingly.
B2 and L2 GPA calculations give students a genuine second chance. A rough first year doesn't have to define your academic story — your best or most recent work can speak louder than your earliest.
GPA Requirements for Graduate and Professional Schools
Canadian graduate and professional programs have specific GPA expectations.
| Program | Typical GPA Requirement |
|---|---|
| Law school (U of T, Osgoode, UBC) | 3.7+ |
| Medical school (Ontario) | 3.7+ (OMSAS GPA) |
| MBA (Rotman, Ivey, Schulich) | 3.3+ |
| Master's programs (minimum) | 3.0 |
| Competitive Master's programs | 3.5+ |
| NSERC / SSHRC scholarships | 3.7+ |
For law school, top schools like U of T, Osgoode, and UBC expect 3.7+ combined with strong LSAT scores. Some schools use your B2 or L2 GPA rather than cumulative. For medical school, most successful applicants have 3.7+ GPAs. Ontario's OMSAS calculates a weighted GPA (wGPA) that may drop your lowest credits. MBA programs at Rotman, Ivey, and Schulich look for 3.3+ alongside GMAT scores and work experience. NSERC and SSHRC research scholarships generally require 3.7+ for a competitive application.
Dean's Honour List and Academic Standing
Most Canadian universities publish a Dean's Honour List (or Dean's List) each year for top-performing students, typically requiring a GPA of 3.5–3.7 while carrying a full course load. Some schools like U of T use "High Distinction" (3.5+) and "Distinction" (3.2–3.49) designations on your transcript. These recognitions are permanent and signal consistency to employers and graduate programs.
Falling below a cumulative GPA of 1.5–2.0 (varies by university) places you on academic probation. Most schools give you one or two semesters to raise your GPA above the threshold, or you face required withdrawal. If you're near this boundary, focus all your energy on your strongest courses and use this calculator's Target GPA mode to build a recovery plan.
How to Improve Your GPA in the Canadian System
Improving your GPA in the Canadian university system requires strategic thinking. Prioritize high-credit courses: performing well in a 6-credit full-year course has twice the impact of a 3-credit half-year course. Check whether your university offers a grade exclusion or replacement policy — some allow you to retake courses and replace the lower grade. Choose your electives wisely, selecting courses that match your strengths and have favourable class averages. If your school calculates B2 or L2 GPAs for certain applications, a strong finish can compensate for a weaker start. Use this Target GPA calculator to model exactly what grades you need in remaining courses to reach your goals.
At many Canadian universities (Waterloo, SFU, UVic, and others), co-op work terms are graded pass/fail and do not factor into your GPA. Use these semesters to recharge academically, gain professional experience, and return to coursework refreshed — without any GPA risk.
