Overview

Alberta uses a percentage-based grading system converted to a 4.0 GPA scale for post-secondary institutions. The University of Alberta, University of Calgary, and other Alberta universities follow this standardized system where the minimum passing grade is 50% (D grade) and grades of 80% or higher represent A-level performance.

Since 2003, Alberta universities have used a four-point letter-grading system for calculating GPAs. The province maintains consistent grading standards across both secondary and post-secondary education, making transitions between educational levels more straightforward for students.

Alberta Key Facts: The 4.0 GPA scale is used at University of Alberta, University of Calgary, and most Alberta post-secondary institutions. High school grades use the same percentage ranges but may vary slightly by school division.

Overview

Ontario universities including University of Toronto, York University, McMaster University, and Western University use a percentage-based grading system that converts to a 4.0 GPA scale. The minimum passing grade in Ontario is 50%, similar to Alberta.

Ontario's grading system features slightly different percentage cutoffs compared to Alberta, particularly for A-level grades. At many Ontario universities, A+ begins at 90%, A at 85%, and A- at 80%, though specific institutions may have minor variations. Some Ontario schools also use numerical scales (0-10) for internal assessments before converting to letter grades and GPA.

Ontario Key Facts: OMSAS (Ontario Medical School Application Service) uses a standardized conversion table for medical school admissions. Some Ontario universities like York use 9.0 scales internally before converting to 4.0 for external reporting.

Overview

Quebec's education system is unique in Canada due to the CEGEP (Collège d'enseignement général et professionnel) system, which sits between secondary school and university. Quebec uses both traditional percentage-based grading and the distinctive R-Score (Cote R) system for university admissions.

The R-Score, officially called "cote de rendement au collégial," is a statistical ranking system that accounts for student performance relative to classmates and course difficulty. R-Scores typically range from 15 to 40, with 30+ considered excellent and required for highly competitive programs like Medicine, Law, and Dentistry at Quebec universities.

Standard Percentage to Letter Grade

Understanding the R-Score

The R-Score formula accounts for three factors:

1. Individual student performance (your grade in the course)
2. Group strength (average performance of students in your class section)
3. Group dispersion (spread of grades in your class section)

This means a grade of 80% in a challenging class with strong students may yield a higher R-Score than 85% in an easier class with weaker performance overall. The R-Score is calculated by the Bureau de coopération interuniversitaire (BCI) and appears on CEGEP transcripts.

Quebec Key Facts:

• R-Scores are only used by Quebec universities (McGill, Concordia, Université de Montréal, etc.)
• McGill uses the Global R-Score, while most Quebec universities use the Program R-Score
• Competitive programs require R-Scores of 28-35+ (Medicine, Law, Engineering)
• Quebec's CEGEP system is unique—2 years pre-university or 3 years technical

Institutional Variations Within Provinces

While provinces provide general grading frameworks, individual universities may have slight variations in their conversion scales. For example, some Alberta institutions use A+ = 4.3, while the standard is 4.0. Always verify the specific grading policy of your institution.

Transferring Between Provinces

Students transferring credits between provinces should expect grade recalculation based on the receiving institution's scale. Quebec's R-Score is not used outside Quebec, so CEGEP students applying to universities in other provinces have their percentage grades converted directly to GPA.

Graduate vs Undergraduate Grading

Graduate programs across all three provinces typically have stricter grading standards. A B (70-76%) is often considered the minimum acceptable grade for graduate courses, whereas undergraduates can pass with D (50%+). Graduate GPAs are calculated separately from undergraduate GPAs.

Professional Program Requirements

Medical schools, law schools, and other professional programs often have specific GPA requirements that vary by province:

• Alberta Medical Schools: Typically require 3.5+ GPA
• Ontario Medical Schools: Use OMSAS GPA conversion (typically 3.7+ competitive)
• Quebec Medical Schools: Require R-Scores of 32-35+ plus interview

International Student Considerations

International students applying to universities in these provinces must have their grades evaluated by credential evaluation services such as WES (World Education Services). Each province's universities may have different minimum GPA requirements for international admissions, typically ranging from 2.5 to 3.5 on the 4.0 scale depending on program competitiveness.
