Ask three Canadian students their GPA and you might get "3.7", "8.2", and "82%" — all describing roughly the same transcript. Unlike the US, Canada never standardized on one grading scale, and the differences matter most exactly when stakes are highest: grad school, scholarships, and professional program applications.
The Four Systems You'll Meet
- 4.0 scale — the most common: A = 4.0, B = 3.0, and so on. Used (with letter-boundary variations) by many schools including UBC-style percentage hybrids.
- 4.3 / 4.33 scale — adds A+ above A (4.3 or 4.33). Common in several Ontario and BC universities. A 4.0 here is not the ceiling.
- 9-point scale — used by some prairie institutions historically; 9 = A+, 8 = A, and so on.
- Percentages — many schools simply report course marks and averages out of 100.
Why Conversions Are Messy
There is no single official conversion table — each receiving institution publishes its own. A rough general mapping many schools use:
| Letter | Percentage | 4.0 scale | 4.3 scale |
|---|---|---|---|
| A+ | 90–100 | 4.0 | 4.3 |
| A | 85–89 | 4.0 | 4.0 |
| A− | 80–84 | 3.7 | 3.7 |
| B+ | 77–79 | 3.3 | 3.3 |
| B | 73–76 | 3.0 | 3.0 |
| C | 63–66 | 2.0 | 2.0 |
Treat that as directional, not authoritative — a "B+" percentage band at one school is another school's "A−". When an application asks for a GPA on a specific scale, use their published conversion, not a generic one.

What Grad Schools Actually Look At
- Your last two years usually count most — many programs compute admission averages on the final 60 credits, which is good news for slow starters.
- Trend beats average. An upward trajectory with a weak first year reads better than the same GPA declining.
- They convert for themselves. Admissions offices routinely re-compute your average on their own scale from the transcript — so don't agonize over self-reported conversions; just be consistent and cite the scale.
Practical Tips
Keep your own spreadsheet of courses, credits, and marks from day one — recomputing a weighted average takes seconds when you have the data. When comparing yourself against a program's cut-off, convert conservatively (round down, not up). And if your school uses percentages, report percentages with the scale named, letting the receiving school do its own math.
