Canadian Grading System: Letter Grades, Percentage & GPA
Canadian universities use letter grades paired with a GPA — but whether that GPA runs to 4.0 or 4.3 depends on the institution. This guide explains the common Canadian grading conventions, the key differences between provincial and institutional scales, and how to compare your grades internationally.
Overview of the Canadian Grading System
Unlike countries with a single national grading standard, Canada delegates education to the provinces, and within provinces, universities set their own grading policies. The result is a consistent broad structure — letter grades from A+ to F, paired with a GPA — but meaningful variation in the details.
The two most common GPA scales are the 4.0 scale (used by many Ontario universities including U of T, Western, and Queen’s) and the 4.3 scale (used by UBC, SFU, Alberta, and others), where A+ earns 4.3 points rather than 4.0. Some institutions — including Dalhousie and McGill — use their own variants.
Percentage cutoffs for letter grades also vary. Most Canadian universities require a higher percentage for a given letter grade than US universities do — for example, many set A at 85%+, whereas the US standard is typically 90%+.
Canadian Grade Scale Conversion Table
The table below shows the commonly used letter grades with typical percentage ranges and GPA values on both the 4.0 and 4.3 scales. These ranges are representative conventions — your institution may use slightly different cutoffs.
| Letter Grade | Typical % Range | GPA (4.3 scale) | GPA (4.0 scale) | Description |
|---|---|---|---|---|
| A+ | 90–100% | 4.0–4.3 | 4.0 | Exceptional |
| A | 85–89% | 4.0 | 4.0 | Excellent |
| A− | 80–84% | 3.7 | 3.7 | Very Good |
| B+ | 77–79% | 3.3 | 3.3 | Good |
| B | 73–76% | 3.0 | 3.0 | Above Average |
| B− | 70–72% | 2.7 | 2.7 | Satisfactory |
| C+ | 67–69% | 2.3 | 2.3 | Adequate |
| C | 63–66% | 2.0 | 2.0 | Acceptable |
| C− | 60–62% | 1.7 | 1.7 | Marginal |
| D+ | 57–59% | 1.3 | 1.3 | Minimal Pass |
| D | 53–56% | 1.0 | 1.0 | Pass |
| D− | 50–52% | 0.7 | 0.7 | Minimal Pass |
| F | Below 50% | 0.0 | 0.0 | Fail |
Note: Percentage bands are common conventions, not a national standard. Your university’s official academic calendar is the authoritative source. The 4.3 vs 4.0 distinction applies mainly to A+ — all other grade-point values are the same on both scales.
Notable Provincial & Institutional Differences
- Ontario (U of T, Western, McMaster, Queen’s). Most Ontario universities use a 4.0 scale. A+ is typically worth 4.0 (same as A). Percentage cutoffs often start A at 80–85% depending on the institution.
- British Columbia (UBC, SFU). UBC and SFU both use a 4.3 scale, awarding A+ = 4.33. UBC sets A+ at 90%+, A at 85–89%, and so on.
- Alberta (University of Alberta, U of Calgary). The University of Alberta uses a 4.0 scale; U of Calgary uses a distinct 4.0 scale with slightly different bands. Both set F as the minimum pass failure below 50%.
- Quebec (McGill, Université de Montréal). McGill uses a 4.0 scale where A = 85%+ and D = 55–59%. The minimum passing grade at many Quebec institutions is 60%.

Frequently Asked Questions
Does Canada use a 4.0 or 4.3 GPA scale?
Both scales are used across Canada, and the variation is primarily by institution rather than by province. Many Ontario universities (including University of Toronto, Western, Queens) and several others across the country use a 4.0 scale. Others — including UBC, SFU, and several Quebec institutions — use a 4.3 scale where A+ is awarded 4.3 rather than 4.0. Always check your specific university's official grading policy.
What percentage is an A in Canada?
In Canada, an A grade typically corresponds to 85–89%, with A+ at 90%+. However, this varies significantly by institution. Some universities set A at 80%+ and do not distinguish A+ from A. Others use 4-point bands throughout. The exact percentage cutoffs for each letter grade depend on your university — check its official academic calendar.
What is a good GPA in Canada?
A GPA of 3.0 (B average) is generally the minimum for most graduate school applications and professional programmes. A GPA of 3.5 or higher is considered strong. For competitive programmes (medicine, law, highly ranked graduate schools), a 3.7+ is typically expected. The benchmark also depends on the scale in use — a 3.0 on a 4.3 scale is not the same as a 3.0 on a 4.0 scale.
Is a Canadian GPA equivalent to a US GPA?
A Canadian GPA on a 4.0 scale is broadly comparable to a US 4.0 GPA, since both use the same letter grade-to-point mapping. However, the underlying percentage cutoffs may differ — many Canadian universities require higher percentages for a given letter grade than US schools do. A Canadian A+ on a 4.3 scale is not directly equal to a US 4.0. When applying to US graduate programmes, provide your transcript and let the programme apply its own conversion.
How do Quebec universities grade?
Quebec CEGEPs (pre-university colleges) use a percentage system and letter grades on a scale where 60% is typically the minimum pass. University-level institutions in Quebec vary — some use letter grades and a 4.3 GPA scale, others use their own numeric systems. The Université de Montréal, for example, uses a letter grade system where A+ = 4.3 and the minimum pass is typically D (around 60%).
How do I convert a Canadian GPA to a US GPA?
If both use a 4.0 scale with the same letter grade mapping, the numbers are directly comparable. If your Canadian university uses a 4.3 scale, a rough approach is to normalise: divide your GPA by 4.3 and multiply by 4.0 (e.g., 3.7 / 4.3 × 4.0 ≈ 3.44). However, US graduate programmes often prefer to see your original GPA alongside the institutional scale rather than a self-computed conversion.
