Academic grading in Canada varies by province, level of education (high school or university, e.g.), institution and faculty (for example, Ryerson or Université du Québec à Montréal). The following are commonly used conversions from percentage grades to letter grades, however, this is not necessarily meaningful, since there is not a uniform scheme for assigning percentage grades either.

In British Columbia:

• A: 86-100
• B: 73-85
• C+: 67-72
• C: 60-66
• C-: 50-59
• I : 49 and below (temporary)
• F : 49 and below (permanent)

In Alberta:

• A: 80-100
• B: 65-79
• C: 50-64
• D: 0-49

In Newfoundland and Labrador:

• A+: 90% - 100%
• A: 85% - 90%
• A-: 80% - 84%
• B+: 75% - 79%
• B: 70% - 74%
• B-: 65% - 69%
• C: 60% - 64%
• C-: 55% - 59%
• D: 50% - 54%
• F: 0% - 49% (Grade F is the sole failing mark.)

In Ontario:

• A (Level 4, above government standards) 80% and above
• B (Level 3, at government standards) 70-79%
• C (Level 2, below, but approaching government standards) 60-69%
• D (Level 1, well below government standards) 50-59%
• R (Remedial standards-used in elementary schools), or F (Failing standards-used in high schools), 49% and below.

There are also + and - modifiers. A+ is close to 100% and better than A, A is better than A-, A- is better than B+. So on and so forth. There are no modifiers for R. Some teachers will assign a level number instead of a letter grade. For example, a "4+" corresponds to A+, 2 corresponds to C, and 1- corresponds to D-. Grades using this system do not have an R or F grade.

In Saskatchewan:

• A+: 90-100%
• A: 80-89%
• B: 70-79%
• C: 60-69%
• D: 50-59%
• F: 0-49%

In elementary schools "M" may be used to indicate a student is in a modified program (for children with learning disabilities, etc.)

Senior 1-4:

Grade 9-12 students need to obtain 30 credits in 4 years. The credits are given on a pass-fail system. Each teacher creates his own standard of the pass-fail line. The line can be no less than 50% and no greater than 70%. When the student completes Senior 4 a class rank based on the curve will be put on his transcript.

In Quebec

• A+:100(Best)
• A :95 (above standards)
• A-:90 (above standards)
• B+:85 (above standards)
• B :80 (at government standards)
• B-:75 (at government standards)
• C+:70 (at government standards)
• C :65 (lower standards)
• C-:60 (lower standards)
• D+ :55 (Failure)
• D :50
• D-:45
• E+:40
• E :35
• E-:30

At a high school level, each subject is separated in three competencies. On report cards, marks are shown as letters and an average of the three marks associated to the subject will be calculated, For example, if a student achieves A, A- and B+ in a subject, teachers will calculate an average of the three marks (in this case, 90%).

Quebec passing mark is 60% and not 50% as compared to some other provinces. Also worth note the military pass mark is also generally 60%.
