OLSAS GPA calculator

Enter your transcript and see the GPA the Ontario Law School Application Service works out from it: every course converted to the 4.0 scale on your university's own column, weighted by its length. Then see the years each Ontario law school says it reads.

For entry in 2027, applications and transcripts are due at OLSAS by 1 November 2026, 11:59 pm Eastern. Fall 2026 grades are due by 1 February 2027.

The conversion to 4.0 depends on the university, so choose it first. Until you do, the sample below is converted as percentage marks.

OLSAS cumulative GPA

3.66out of 4.00

From 25 courses, 30 half-courses, converted by percentage on OUAC Scale 3. These are sample marks.

OLSAS cumulative GPA 3.66 out of 4

Best three years · Toronto
3.66

From years 1, 2 and 3. Toronto starts from your best three full-time years, fall and winter only, then reads the whole record.

Top two years · Queen's
3.77

From years 2 and 3. Queen's reads your top two years at a full course load. It does not publish what a full load is; this counts fall and winter years of at least 6 half-courses, OLSAS's own full-time line.

Last two years · Western
3.77

From years 2 and 3. Western counts back 20 half-courses, summer included, and gives them more weight when the cumulative is under about 3.7. It counts back by semester; this counts back by whole years, so it can take in a few more courses.

How OLSAS works the number out

From the OUAC's OLSAS GPA Calculations page and its Undergraduate Grade Conversion Table, read on 2 October 2026. The rules are checked again every application cycle.

Each course is converted on its own
OLSAS converts every course grade to a value out of 4.00 with the OUAC Undergraduate Grade Conversion Table, using the column the table assigns to your university. The table has nine columns and the highest value is 4.00: on Scale 3 a mark of 90 to 100 is 4.00 and 85 to 89 is 3.90.
A course counts by its length
A full-year course counts 2, a half-year course 1, a three-quarter course 1.5 and a lab course 0.5. The cumulative average is each converted grade times its length, added up, divided by the lengths added up. OLSAS notes that this is not an average of the yearly averages.
Percentages win over letters, and letters are not translated
Where a transcript shows both a percentage and a letter for a course, the percentage is used. A transcript with letters only is converted from the letters, and OLSAS tells applicants not to reconcile letters against the percentage scales.
Nearly everything counts
Failed, repeated, incomplete and supplementary courses are included, and so are summer courses and courses beyond what your degree required. A repeated course does not replace the first attempt. Courses with no specific grade, a Pass for example, are left out, as are challenge-for-credit courses. Grades from outside Canada and the United States are not converted; the transcript goes to the schools.
A year is two semesters
OLSAS groups a transcript into academic years: two consecutive semesters make one year, and co-op semesters are grouped the same way. Part-time, summer and intersession courses in a calendar year are grouped together, apart from the fall and winter. Its full-time code needs at least three full or six half courses across the two semesters.
The schools may read it differently
OLSAS produces one cumulative average. Its guide says each law school may use a different GPA from the one OLSAS calculates, which is why the table below matters. From December you can see OLSAS's own calculation in Document Tracking.

What each Ontario law school reads

From each school's own admissions pages and its page in the OLSAS guide. No school publishes a minimum GPA. Medians are the ones each school printed for its most recent class, and a figure is one part of a file that also has an LSAT score, a statement and references.

SchoolWhat it says it readsSource
University of TorontoStarts from your best three full-time undergraduate years, traditionally the fall and winter sessions, then reviews the whole record, summer and graduate courses included. Median for the class entering in 2026: 3.91.Admissions policies
Osgoode Hall, YorkThe cumulative GPA across all years of undergraduate study. Pass and credit notations are not in it. Median CGPA for the class entering in 2026: 3.78.Application components
Queen'sYour top two years of undergraduate study at a full course load. Queen's has not published how it defines a full load. Its profile for the class of 2028 gives a top-two-year GPA of 3.72.Admission categories
WesternThe cumulative GPA over every graded undergraduate course, spring, summer and exchange terms included. When that is under about 3.7, more weight goes to the last two years, which Western counts as your last 20 half-courses with semesters kept whole. Medians for 2026: 3.70 cumulative, 3.76 over the last two years.Grades and courses FAQ
University of Ottawa, English common lawThe cumulative GPA over every undergraduate semester. Every year counts. Graduate, college and CEGEP grades are left out. No median is published.Admissions FAQ
WindsorNo GPA figure is stated. Your undergraduate average and the trend in it are part of one of seven criteria, and no single criterion decides.Admissions criteria
Lakehead, Bora LaskinThe cumulative GPA OLSAS calculates over all undergraduate university courses, read beside the yearly breakdown. The school says it does not drop low grades and does not read only the best two years. It publishes no GPA statistics.Admission questions

Questions applicants ask

Is this my official OLSAS GPA?
No. It is the same arithmetic on the grades you type. OLSAS makes the official calculation from the transcripts your universities send, and from December you can see it in Document Tracking.
I repeated a course. Which attempt counts?
Both. OLSAS includes repeated courses and does not replace the first attempt, so enter each attempt as its own row. Your university may count only one in its own average, which is one reason the two numbers differ.
What do I do with a pass/fail course?
Leave out a course that shows a Pass or a credit with no grade. OLSAS does not include a course without a specific grade. Its guide does not say how a Fail in a pass/fail course is treated.
Do summer courses count?
Yes, in the cumulative GPA. OLSAS groups summer and part-time courses apart from the fall and winter. Toronto's best three years and Queen's top two years are built from fall and winter courses, while Western counts summer terms in its last two years. Add them with "Add a summer course" under the year they follow.
What about the courses I am taking now?
The transcript you send in the autumn does not carry this year's results. Fall 2026 grades go to OLSAS by 1 February 2027. The schools differ after that: Toronto Metropolitan counts only what was finished by the end of the summer, and Western includes the fall grades.
What are L2, B2 and B3?
Shorthand applicants use for the last two years, the best two years and the best three years. None of them is an OLSAS term. Western calls its figure Last 2, Queen's says top 2 years, and Toronto describes its best three academic years, so this page uses the schools' own words.
My university is listed on two scales. Which one applies?
Queen's, Toronto, Waterloo and Windsor are listed on both Scale 3 and Scale 7, and the table does not say which applies when. OLSAS does say that a percentage is used wherever a transcript shows one beside a letter, so this page converts percentages on Scale 3 and, for a transcript that prints letters only, the letters on Scale 7.
Is anything I type saved?
No. The arithmetic runs in your browser and the page keeps nothing. If you choose to keep the years, they are saved to a free Gradus account that you create.

This is an estimate. OLSAS makes the official calculation from your transcripts.

The conversion and the weights follow the OUAC pages named above. The figures for Toronto, Queen's and Western are this page's reading of what each school states, built from years of study as you entered them; each school applies its own judgment to co-op terms, exchanges, part-time loads and anything unusual. Check the current OLSAS guide and each school's admissions pages before you rely on a number.

Keep the figure current while the term is still running

Gradus is a grade tracker built by a computer science student at Trent University. It keeps the years you have finished, tracks this term's courses as marks come back, and shows the same 4.0 figure moving as they do.
