• TSSA Gas Technician 3

    The Technical Standards and Safety Authority (TSSA) offers the Gas Technician 3 licence (G.3 licence). A G.3 licence allows you to work as a technician within the gas service industry under the direct supervision of a G.1- or G.2-licenced gas technician.

    Individuals who complete the TSSA-approved G.3 training and pass the related provincial qualification exam are eligible to receive the G.3 licence from the TSSA. The TSSA awards the licence. However, George Brown College Continuing Education has been recognized by the TSSA as an approved provider of both the Gas Technician training courses and the required provincial qualification exams.

    For more information about the G.3 licence, visit the Training and Certification web page on the TSSA website.


    Course Requirements:

    If you have passed our HVAC 9043 Gas Technician 3 Theory course or you wish to challenge the exam without completing the training course, you can register for EX 9000 TSSA Gas Technician 3 Exam: Challenge instead of completing the course requirements listed here. (If you pass the challenge exam, you will be required to complete a practical skills assessment conducted by a TSSA Training and Certification advisor.)
