What can a GUT-2 holder legally do in Ontario?
While working as an employee of a natural gas distributor, a GUT-2 holder may inspect, test, purge, activate or remove a natural gas appliance up to 400,000 Btuh and its essential equipment. In doing that work, the holder may:
- Perform the GUT-1 functions on appliances within the 400,000 Btuh limit
- Work above that limit only under the direct supervision of a GUT-1 holder
Boundaries of the GUT-2
- The certificate operates only during hours employed by a natural gas distributor (O. Reg. 215/01, s. 52.3)
The full scope wording is in O. Reg. 215/01, s. 52.3, which prevails over any summary.
Is a certificate legally required for gas work?
Under O. Reg. 212/01 (Gaseous Fuels), s. 6 (1), no person may install, alter, purge, activate, repair, service or remove any appliance or equipment used in the handling or use of gas unless they hold a certificate for that purpose. The only exception is working in the physical presence of someone who holds the appropriate certificate.
The requirement is in O. Reg. 212/01, s. 6 (1). Working without the certificate is an offence under the Technical Standards and Safety Act, 2000.
How do you get the GUT-2 in Ontario?
Prerequisite
None stated in O. Reg. 215/01 beyond the approved program and exam, but the certificate only operates while the holder is employed by a natural gas distributor.
The training route
- Complete an approved program at an accredited training provider. Certification requires a TSSA-approved curriculum delivered by an accredited provider (O. Reg. 215/01, s. 5 (1)).
- Apply for the TSSA certification exam. Your provider submits proof of training; you book through the TSSA Client Portal. The practical assessment stays valid for 12 months after the program.
- Pass the TSSA certification exam. Each attempt, including rewrites, is billed as a separate exam. Failing three times means completing a full accredited program before another attempt (O. Reg. 215/01, s. 5 (4)).
- Pay the certificate fee. $136 for the initial certificate (from May 1, 2026, plus HST), per the TSSA Natural Gas & Hydrogen Fee Schedule.
The challenge route
Experienced workers can challenge the exam without formal training if TSSA is satisfied they hold equivalent knowledge and competence (O. Reg. 215/01, s. 5 (5)). The challenge examination costs $255.50, requires documented proof of work experience where the certificate has prerequisites, and still ends in a practical skills assessment.
How often does the GUT-2 need to be renewed?
Every two years. TSSA's fee schedules list the certificate fee as biennial, and the renewal costs $136 (from May 1, 2026, plus HST) with a $50 late payment fee after the renewal date.
Working on an expired certificate is prohibited outright: O. Reg. 215/01, s. 4 (1) says a person who fails to renew shall not do any work under the certificate after expiry. You can still renew up to one year after expiry, completing any upgrading course the director specifies. After one year, the certificate is gone and you start over as a new applicant (s. 4 (5)).
