About TSSA
The Technical Standards and Safety Authority (TSSA) is the regulatory body responsible for operating engineer certification in Ontario under Ontario Regulation 219/01: Operating Engineers.
Note: Ontario uses the term "Operating Engineer" rather than "Power Engineer" and has four classes (4th through 1st) rather than five.
Exam Structure by Class
TSSA administers operating engineer exams following the SOPEEC (Standardization of Power Engineers Examination Committee) syllabus.
| Class | Papers | Format | Duration | Pass Mark |

| 4th Class | 2 (A, B) | 100 multiple-choice each | 3 hours each | 65% |
| 3rd Class | 4 (A1, A2, B1, B2) | 100 multiple-choice each | 3 hours each | 65% |
| 2nd Class | 6 | 100 multiple-choice each | 3 hours each | 65% |
