Program Overview

The Gas Technician 3 (G.3) certification program provides training for individuals who want to qualify as a Gas Technician 3. The program, consisting of 180 hours, has been divided into three courses in order to modularize delivery. Each course consists of the required theoretical or practical components as outlined by the Technical Standards and Safety Authority (TSSA).

Upon completion of the program and when the TSSA requirements are met, students are eligible to write the TSSA Certificate of Qualification Exam for Gas Technician 3. The TSSA requires that students achieve 75 percent as the final grade in each of the G3 courses, as well as maintain at least 80 percent attendance.
