Canadian Provincial Grading Converter
Mix courses across provinces. Ontario/Alberta/BC use percentages; Quebec CEGEP uses a 0–10 scale. Defaults: pass ≥ 50% (ON/AB/BC) and ≥ 6/10 (QC). Letter mapping uses a common Ontario-style scheme (editable).
Customize letter cutoffs (lower bounds, %)
These are common heuristics; districts vary. Choose “BC-like” to auto-load A (86), B (73), C+ (67), C (60), C− (50) (others approximate).

Disclaimer: Provincial grading practices vary by school/district and year. This tool applies common heuristics: Ontario/Alberta/BC percentage inputs (typical pass 50%), Quebec CEGEP 0–10 (pass 6/10). Adjust cutoffs if needed.
Frequently Asked Questions (2025)
1) Is there an official Canada-wide high-school GPA scale?
No. Provinces control K-12, and each university/college can define its own GPA table. Use the destination’s published rules when available; otherwise disclose a neutral linear conversion.
2) I’m in Ontario. Do I report a letter or a percent?
Ontario high schools report percentages; report the percent and let the destination compute letters/GPA from its own table. Ontario’s policy also clarifies < 50% is failing.
3) What is the Quebec R-score, and can I turn it into a GPA?
The R-score is a CEGEP standardized metric incorporating z-scores plus group strength/dispersion to contextualize your grades; it’s on a 0–50 scale (most students fall around 15–35). It’s not a GPA and shouldn’t be converted; list it as is and convert course percents only if a GPA is required.
4) I’m in BC. My transcript has both letters and percentages. Which do I use for GPA?
Use percentages if the destination’s table is percent-based, because BC’s letter bands at K-12 (A=86–100, etc.) aren’t necessarily the same as a university’s internal bands.
5) Alberta Diplomas: do I enter the school mark or the blended final?
The final Grade 12 course mark includes the Diploma Exam (back to 30% since Sept 1, 2023). Enter the final as it appears on your transcript.
6) My destination wants a 4.33 maximum (A+ system). Do I just scale my percent?
If they don’t publish a table, yes: linear map to 4.33 and disclose the method. If they do publish one, use theirs.
7) Manitoba programs mention 4.5 GPAs. How do I convert?
Use a 4.5 ceiling (linear or table-driven) per the program’s instructions. Manitoba universities (e.g., UManitoba) publish 4.5 equivalencies for Canadian institutions.
8) Do I average my high-school courses equally?
If the destination requests an overall GPA and doesn’t specify otherwise, a credit-weighted mean is best; otherwise state that you used a simple mean. Universities often recompute anyway.
9) Should I trust random “Canada GPA” charts online?
Treat them as heuristics only. Prefer official university calendars, provincial legends (for K-12), or OUAC/BCI documents.
10) I’m from Yukon. Do I follow BC tables?
Yukon follows BC curriculum and uses BC-style letter↔percent equivalences for Grades 10–12; for university GPAs, use the destination’s table.
11) I converted my percent to 4.0 but the university shows a different GPA after admission. Who’s right?
The university’s calculation is authoritative for their records. Your self-reported figure is for form compliance only.
12) Can I include both my percent and my self-computed GPA?
Yes—and it’s wise. Include a one-line method note so reviewers see your transparency.
13) Do A and A+ both equal 4.0 at some schools?
Yes. Many 4.0 institutions cap the grade point at 4.0 (A and A+ both 4.0). Others use 4.33 for A+. Always check the destination’s table (e.g., UBC’s page shows per-faculty bands).
14) I need to reconstruct an AB final from my school mark + Diploma. How exactly?
Use (policy since Sept 1, 2023). Then convert the final to the required GPA, not the school mark alone.
15) Is there ever a reason to convert R-score to percent?
No. Report the R and your course marks separately; destinations that know Quebec will read R natively.
