This Canada GPA calculator and its grading scales follow the rules Canadian universities publish: the University of Toronto's grade points and its Arts & Science GPA rules, and the grading scales of UBC Vancouver and York University. Every rule links to the page it comes from, with the date GradeCat opened it. Each tool works right away with no account, and your marks stay in your browser.
Tools
Which tool to use when
You want your UofT GPA or CGPA: use the University GPA Calculator. Pick each course's credits, 0.5 for a half course or 1.0 for a full course, and its grade. It gives your sessional GPA and CGPA, unrounded, because UofT states no rounding rule, and the Arts & Science distinction band your CGPA is in.
You are in Grade 12 in Ontario: use the Ontario Top 6 Average Calculator. It adds your highest marks over six credits, says whether you reach the 480 an Ontario Scholar needs, and gives your average of those six.
You want to know what a mark or a letter is worth: see the University Grading Scale in Canada. It has the UofT, UBC Vancouver and York scales, and a lookup: 82% is an A- at UofT, worth 3.7 grade points.
You want your percentage from marks: the Grade Calculator adds up marks out of any total, and the Weighted Grade Calculator combines parts such as labs, a midterm and a final with their weights.
You want the mark you need on a final exam: the Final Grade Calculator works it out from your mark so far and the final's weight.
Guides
- How GPA works in Canada: why there is no national scale, UofT's sessional and cumulative GPA, and the Ontario Scholar, Alberta, UBC, York and Quebec R score rules, with worked examples.
How university grading works in Canada
Canada has no national university grading scale: each university publishes its own. At the University of Toronto, a grade carries points on a 4.0 scale, and an A- (80 to 84%) is worth 3.7, as its Grading Practices Policy sets out. UBC Vancouver reports percentages and letters, with no 4.0 points on its grading page. York University uses a 9-point scale, from A+ (9) down to F (0).
The same mark can earn a different letter at each one: 76% is a B at UofT and a B+ at UBC Vancouver. Check your own university's scale before you compare grades.
Tools that work with any marks
These GradeCat tools work with marks and percentages, which add up the same way anywhere. Their letter grades follow US scales, so read the percentage they give.

- Final Grade Calculator: the mark you need on a final that counts for a set share.
Not covered yet
- Quebec's R score (cote R), which universities use to select students coming from CEGEP.
- UBC averages and York GPAs as calculators. The grading scale page has both scales, but York's page gives no GPA method.
