Before the work starts
Permis dont vous aurez besoin
Permis requis pour les travaux de cvc en Ontario
TSSA Gas Permit
Required for all work on gas-fired equipment including furnaces, boilers, water heaters, and gas fireplaces. Only TSSA-certified gas technicians can perform this work.
ESA Electrical Permit
Required for electrical components of HVAC systems including wiring for furnaces, air conditioners, heat pumps, and thermostats that involve new circuits.
Municipal Building Permit
Required when HVAC work involves ductwork modifications, structural changes, or is part of a larger renovation or new construction project.
Gas work and electrical work each require their own separate permits and inspections. One does not cover the other.
Converting between heating fuel types (e.g., oil to gas) typically requires both TSSA and municipal permits.
Homeowner Tip: Ask your HVAC contractor to confirm which permits are needed for your specific project. A furnace replacement may need both a TSSA gas permit and an ESA electrical permit.
