What is a TSSA inspection

A TSSA inspection is a safety inspection conducted by the Technical Standards & Safety Authority to ensure fuel-burning equipment meets Ontario safety codes and regulations. TSSA inspectors verify that gas appliances like furnaces, water heaters, and fireplaces are installed correctly and operating safely.

TSSA inspections are required whenever you install or significantly modify gas-burning equipment in Ontario. This includes new furnace installations, gas fireplace installations, and major repairs to existing gas appliances. The inspection ensures the work meets current safety standards and that there are no carbon monoxide risks or gas leaks that could endanger your family.

During a TSSA inspection, the inspector will check several critical safety elements. They'll verify proper venting and combustion air supply, test for gas leaks, ensure adequate clearances from combustible materials, and confirm that carbon monoxide levels are within safe limits. They'll also check that the installation matches the approved permit and that all components are properly sized for your home.

In Ottawa, TSSA inspections typically cost between $100-150 and must be scheduled after installation work is complete. Your licensed HVAC contractor will usually arrange the inspection as part of the installation process. The inspector will provide a certificate of compliance once everything passes, which is important for insurance purposes and future home sales.

Only TSSA-licensed technicians (G2 or G3 gas fitters) can perform work that requires TSSA inspection. Attempting DIY work on gas appliances is both dangerous and illegal in Ontario. If you're planning any gas appliance installation or major repairs, ensure your contractor is properly licensed and will handle the permit and inspection process.

TSSA requirements may vary depending on your specific installation - always confirm requirements with your licensed HVAC technician who can guide you through the proper permitting and inspection process for your project.
