Do I need a permit to install a furnace in Ottawa

Yes, you need a TSSA permit to install a furnace in Ottawa. This is required by law for all fuel-burning appliances in Ontario, and only licensed G2 or G3 gas technicians can obtain these permits and perform the installation.

The Technical Standards & Safety Authority (TSSA) regulates all fuel-burning equipment installations in Ontario, including furnaces. Your HVAC contractor will handle the permit application process as part of the installation. The permit ensures the installation meets safety codes and includes a mandatory inspection by a TSSA inspector after completion. This inspection verifies proper venting, gas connections, electrical work, and overall safety compliance.

In Ottawa, furnace installations typically require both the TSSA permit for the gas appliance and may also need an electrical permit from the city if significant electrical work is involved. The permit costs are usually included in your contractor's quote, ranging from $100-200 for the TSSA permit. Most reputable HVAC companies handle all permitting as part of their service.

Never attempt to install a furnace yourself or hire unlicensed contractors. Improper installation can lead to carbon monoxide poisoning, gas leaks, fires, or voided insurance coverage. Insurance companies may deny claims if work wasn't done by licensed professionals with proper permits. Additionally, when you sell your home, buyers and home inspectors will look for permit records.

Choose a licensed HVAC contractor who will handle permits, installation, and the required TSSA inspection. This ensures your new furnace is safe, code-compliant, and properly warrantied.
