Your university's GPA is the official one, and schools and application services convert grades with their own rules.

How the GPA calculator works
Start with your university. That's what decides the table. OUAC, the Ontario Universities' Application Centre, publishes one Undergraduate Grade Conversion Table and lists 60 Canadian universities beside the scale it converts each one by. There are nine scales in that table and six in use. Yours shows under the menu, so you can check it against OUAC's own list.
Each course gets converted on its own. Its mark or letter turns into points, and the points get multiplied by the course's credits. Add those up across your courses, divide by all your credits together, and that's your term GPA. If every course carries the same weight, it's just the average of the points.
Where we hold your university's own scale, you get two numbers, and the difference is real. At U of T an 87 is an A, worth 4.0 on U of T's own scale. OUAC's table turns the same 87 into 3.9. So the U of T example term comes out at 3.26 on the U of T scale and 3.24 converted with OUAC's table. Neither one is a mistake: your transcript speaks U of T's scale, and a form that asks for OUAC's conversion wants the second number.
Percentages follow OUAC's route too. For 22 universities OUAC reads the mark straight off a percentage scale. UBC isn't one of them: OUAC converts UBC from the letter on Scale 7, so we find your letter in UBC's own bands first. That's how a 76 ends up a B+ and 3.3 at UBC, and a 3.0 at a university on Scale 3.
Cumulative works across terms the same way: your earlier figure times your earlier credits, plus this term's points, all divided by every credit. Pick the scale your earlier figure is on, because a U of T 3.41 and an OUAC 3.41 aren't the same thing. The goal line runs that sum backward and rounds what you'd need up, never down.
We work everything out exactly and round half-up to two decimals only at the very end. That's why an exact 3.475 shows as 3.48, not the 3.47 that a computer's shortcut arithmetic lands on.
One call here is ours, and you should know about it. OUAC's table lists whole marks, and Queen's stops its A at 89.9, so a mark with decimals can fall between two rows. When we checked both on Oct 7, 2026, neither said where such a mark belongs. We count it in the lower row, which puts an 84.5 in 80-84 and keeps a Queen's 89.95 an A.

Who this is for
An undergraduate U of T student with a scholarship form that wants a GPA "on a 4.0 scale". A Queen's student in Arts and Science, Smith School of Business, Smith Engineering, Graduate Studies or Health Sciences. A York undergraduate who knows the 9-point number and needs the 4.0 one for an exchange. A UBC student whose faculty uses the common grading table. And a high-school student filling in a US application, as long as the number is read as a reference.
Student questions about GPA in Canada
Why does every Canadian university seem to use a different scale?
Because each one sets its own. U of T gives grade points out of 4.0, Queen's goes up to 4.3 for an A+, York uses a 9-point scale, and UBC grades in percentages with letter bands and no grade points at all. OUAC's conversion table exists to line them up: it lists 60 universities and the scale it converts each one by.
What is OUAC's conversion table, and why is my A only a 3.9?
It's the Ontario Universities' Application Centre's Undergraduate Grade Conversion Table, which OUAC says "is used for converting individual grades only." On its letter Scale 7 an A+ is 4.00 and an A is 3.90, and on percentage Scale 3 marks from 85 to 89 are 3.90. So a U of T A, a 4.0 on U of T's own scale, becomes 3.9 once converted. Both numbers are right, just for different forms.
What is an 85 in GPA?
Converted with OUAC's table, an 85 is a 3.9 on every percentage scale OUAC uses: Scale 3 lists 85 to 89 at 3.90, and Scales 4 and 6 put an 85 there too. On U of T's and Queen's own scales an 85 is an A, worth 4.0. Pick your university and you'll get the numbers that apply to you.
What is a 90 average in GPA in Canada?
It depends on the marks behind it, because OUAC converts each course, not your average. Two 90s make a 4.00 on Scale 3, but only a 3.90 at Memorial, where Scale 6 starts 4.00 at 94. An 80 and a 100 also average 90, yet convert to 3.85. Type the marks, not the average.
Why is a 76 a 3.3 at UBC but a 3.0 somewhere else?
Because the route differs. UBC's calendar puts 76 to 79 at B+, and OUAC converts UBC from the letter on Scale 7, where a B+ is 3.30. A university on percentage Scale 3 has 76 in its 73-76 row, which converts to 3.00. Run every passing mark through both routes and UBC's comes out ahead at 18 of them. It's never behind.
How do I convert York's 9-point GPA to 4.0?
Course by course, not by dividing. OUAC converts York on letter Scale 9: an A+ is 4.00, an A 3.80, a B+ 3.30, and both failing grades, E and F, count 0. The tempting shortcut, scaling the 9-point GPA by four-ninths, gets it wrong: a 7.17 turns into 3.19 that way, while the same courses convert to 3.37. Pick York, enter your letters, and you'll see both figures.
Does Queen's 4.3 scale carry straight over to 4.0?
No, and the whole difference sits at the top of the scale. At Queen's an A+ is 4.3 and an A is 4.0, but OUAC converts Queen's letters on Scale 7, where an A+ is 4.00 and an A is 3.90. Every A+ and A loses a little. An A+, an A- and a B over equal units make a 3.67 at Queen's and a 3.57 converted.
How do I calculate my cumulative GPA?
Multiply your earlier GPA by your earlier credits, add this term's grade points, and divide by all the credits together. Don't just average the two GPAs. With 5 earlier credits at 3.41 on the U of T scale and the example term's 3.26 over 2.5 credits, the cumulative is 3.36, while a plain average says 3.34. Keep both figures on one scale and the credits in one unit.
Does a failed course count in my GPA?
Usually, yes. A fail is worth 0 points and its credits still count, so it pulls hard. York is the odd one out: an E, a marginal fail, is worth 1 point on York's 9-point scale, though OUAC's Scale 9 counts E and F alike at 0. Pass/fail is another story. Queen's says it plainly: "P/F grades are not factored into the calculation of the GPA." Leave those courses out here too.
Is this the GPA OMSAS or a law school will use?
Not necessarily, and we'd rather say so plainly. OUAC's table converts individual grades, and its own page says the GPA is only one of several factors in admission to law school, medical school or rehabilitation sciences. An application service can apply its own rules on top. What you get here is your marks, converted. It isn't an OMSAS or OLSAS GPA, and we don't try to compute one.
Can I use it for high-school marks?
As a reference, yes. Pick Not listed / high school and type your percentages: they go through OUAC's Scale 3, our choice because OUAC uses it for 20 of the 22 universities it converts from percentages. OUAC's table was written for university grades, though, and a college that asks for your GPA may convert your transcript its own way. And it isn't an Ontario admission average, which is a different calculation altogether.
Percentage to GPA in Canada
Converting a percentage to a GPA takes two lookups. Find your university on OUAC's list to learn its scale, then read each mark on that scale. On Scale 3, 90 and up is 4.00, 85 to 89 is 3.90, 80 to 84 is 3.70, and so on down to 0 below 50. Multiply each course's points by its credits, add them up and divide by the total credits.
The five U of T marks in the example, 87, 82, 78, 74 and 69, average out to 78. On Scale 3 they're worth 3.9, 3.7, 3.3, 3.0 and 2.3, which makes a 3.24. On U of T's own scale the 87 counts a full 4.0, so the same term is a 3.26.

U of T's rows are its undergraduate scale. Queen's rows are for Arts and Science, Smith School of Business, Smith Engineering, Graduate Studies and Health Sciences; Education and Law differ. York's rows are its 2025-26 undergraduate scale, and its percentages are guidelines only. UBC's rows are for most faculties; some programs fail below 60.
