Pick the scale your school uses, add your courses with their grades and credits, and get your GPA. If your school grades by percentage, switch to percentages for a weighted average and an estimated GPA.

Why Canadian GPAs don’t match
The same letter grade is worth different points depending on the scale. N/A means the scale has no such grade.
| Grade | Toronto 4.0 | OUAC conversion | SFU 4.33 | York 9-point |
|---|---|---|---|---|
| A+ | 4 | 4 | 4.33 | 9 |
| A | 4 | 3.9 | 4 | 8 |
| A- | 3.7 | 3.7 | 3.67 | n/a |
| B+ | 3.3 | 3.3 | 3.33 | 7 |
| B | 3 | 3 | 3 | 6 |
| C | 2 | 2 | 2 | 4 |
| D | 1 | 1 | 1 | 2 |
| F | 0 | 0 | 0 | 0 |
OUAC places Simon Fraser on its own conversion scale, where an A+ is 4.0 and an A is 3.9. SFU’s own scale gives an A+ 4.33 and an A 4.00. So one school can show two different GPAs for the same grades, depending on who is converting and why.
A worked example
Here is a made-up set of five courses: an A at 3 credits, a B+ at 3 credits, a B+ at 6 credits, a B at 3 credits, a C+ at 3 credits. These are the same grades on four scales.
| Scale | Total grade points | Total credits | GPA |
|---|---|---|---|
| 4.0, A+ and A both 4.0 | 57.6 | 18 | 3.20 |
| 4.0 OUAC conversion, A = 3.9 | 57.3 | 18 | 3.18 |
| 4.33, A+ = 4.33 | 57.96 | 18 | 3.22 |
| 9-point, A+ = 9 | 120 | 18 | 6.67 |
Same grades, same credits. The scale decides the number, so a GPA only means something next to the scale it came from.
If your school uses percentages
Some Canadian schools report a percentage average instead of a GPA. Here are three courses: 85% at 3 credits, 72% at 3 credits, 66% at 6 credits.
The weighted average is 867 ÷ 12 = 72.250, so 72.25%. Run through the University of Toronto’s published percentage bands, the marks fall in the A, B- and C bands, and the credit-weighted GPA comes to 2.68. Another school’s bands would give a different estimate.
How the GPA is calculated
- Look up the grade points for each letter grade on your school’s scale.
- Multiply each course’s grade points by its credits or course weight.
- Add up those results, and add up the credits.
- Divide the first total by the second. That is your GPA.
GPA = sum of (grade points × credits) ÷ sum of credits
Assumptions to keep in mind
- There is no national scale in Canada. The four scales here are ones named institutions publish, and your school may use another.
- The OUAC scale is a conversion table for applications, such as to Ontario medical and law programs. It is not any one school’s own GPA.
- Pass, withdrawn and incomplete courses are left out. SFU says P and W have no numerical equivalent, and Toronto says credit/no credit is generally not factored into the GPA.
- If you repeated a course, enter it the way your school counts it. York, for example, uses only the most recent attempt in its calculator.
- The percentage mode uses the University of Toronto percentage bands to estimate a GPA. Schools that report a percentage average, such as UBC, report the average itself.
Mistakes that throw a Canadian GPA off
Using the wrong scale
An A+ is 4.0 at Toronto, 4.33 at SFU and 9 at York. Pick the scale your transcript uses, or the number will not match.
Using the application table as your school GPA
OUAC converts grades for applications. It gives an A a 3.9, where Toronto gives it a 4.0 and SFU gives it 4.00 on its own scale. Use it for the application it was made for.
Mixing up credits and course weights
Some schools weight courses as 0.5 or 1.0, and others as 3 or 6 credits. The GPA is the same either way, as long as you use one system for every course.
Counting pass/fail or withdrawn courses
A P or a W normally has no grade points. Entering it as a 0 pulls your GPA down for nothing. Use the options that say not counted.
Averaging letter grades without credits
A 6 credit B+ counts for twice what a 3 credit one does. Averaging the grade points without the credits gives the wrong GPA.
Questions students ask
Which GPA scale does Canada use?
There isn’t one. Toronto gives an A+ and an A both 4.0, Simon Fraser gives an A+ 4.33, York uses a 9-point scale, and UBC grades most courses by percentage. The OUAC publishes a separate conversion table for applications. Pick your school’s scale above.
What’s a good GPA in Canada?
It depends on what you need it for. Programs and scholarships publish their own minimums, and the scale matters, since a 3.7 on a 4.0 scale and a 7 on York’s 9-point scale mean different things. The target GPA calculator shows what you need to reach a minimum.
How do I convert my Canadian GPA to a US 4.0 GPA?
Check what the school asks for first. Many ask for your grades as they are, and some use a credential evaluator. The percentage to GPA converter shows what published tables give for a percentage, and it’s an estimate.
Do pass/fail and withdrawn courses count?
Usually not. SFU says P and W have no numerical equivalent and do not affect the GPA, and Toronto says credit/no credit is generally not factored in. Use the not counted options for those courses.
What if my school uses percentages?
Switch to percentages above. You get the weighted percentage average, which is what schools like UBC report, and an estimated GPA through Toronto’s published percentage bands. If you apply abroad, check how the school wants it converted.
