What can a OBAT holder legally do in Ontario?
An OBAT holder may reactivate an oil-fired appliance up to 7 US gallons per hour input and its accessories. In doing that work, the holder may:
- Replace the filters on the oil supply line to the appliance
- Bleed the oil pump or fuel unit
- Reactivate an existing customer's equipment per the manufacturer's lighting instructions after a loss of fuel supply
Boundaries of the OBAT
- An OBAT holder must not perform the initial activation of a new or newly converted appliance (O. Reg. 215/01, s. 46 (3))
The full scope wording is in O. Reg. 215/01, s. 46, which prevails over any summary.
Is a certificate legally required for oil heat work?
The oil burner certificates are required to perform work regulated under O. Reg. 213/01 (Fuel Oil); O. Reg. 215/01, s. 2 (1) lists them among the certificates that must be held to do that work.
How do you get the OBAT in Ontario?
Prerequisite
None beyond the approved training program and exam.
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 Liquid Fuels & Fuel Oil 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 OBAT 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)).
