Proof of G3 Work Experience for Challenge Certificate Holders
Starting January 1, 2026, the Technical Standards and Safety Authority (TSSA) will enforce a new requirement for Gas Technician 3 (G3) certificate holders who earned their certification through the challenge process to provide proof of 450 hours of G3 work experience to enable enrolment in a G2 program.
This new requirement seeks to ensure that candidates who obtained certification through a challenge process — specifically those who take an exam for a certificate without attending formal training — possess the necessary practical experience before pursuing higher certification in G2.
The Role of Employers of G3 certificate holders
Employers of Gas Technicians and Oil Burner Technicians can support G3 challenge certificate holders in their pursuit of G2 certification by:
- Offering relevant work experience: This helps G3 certificate holders to obtain the necessary 450 hours of work experience so that they can apply to a G2 program.
- Providing letters of experience: An acceptable proof includes a letter from the employer on company letterhead confirming the candidate’s G3 work experience.
Announced in March 2025, TSSA deferred the enforcement of this requirement to January 1, 2026, to give accredited training providers time to adjust their screening processes for G2 program applicants.
TSSA continues to explore ways to help accredited training providers identify candidates who obtained their certificate through the challenge process.
