TSSA (Technical Standards and Safety Authority)
TSSA is the Ontario regulator responsible for licensing and inspecting gas-fired heating equipment, fuel-burning appliances, and related trades across the province. Any furnace, boiler, or gas-fired water heater installation in Ontario falls under TSSA's licensing and code requirements.
Why this matters to you
Hiring a TSSA-licensed contractor isn't just a formality — it's what protects you if something goes wrong with a gas installation, and it's typically required for insurance, warranty, and safety compliance on gas-fired equipment.
Halton Hills note
Every gas furnace, boiler, or water heater install in Halton Hills falls under TSSA rules regardless of contractor size — always ask to see a current TSSA licence number before work begins on gas-fired equipment.
