How do I verify my HVAC contractor is licensed

In Ontario, you should verify that your HVAC contractor holds proper TSSA licensing for gas work and is registered with WSIB for insurance coverage. This protects you from liability and ensures the work meets safety standards.

TSSA License Verification is the most critical step. Any contractor working on gas furnaces, fireplaces, or other fuel-burning equipment must hold a G2 or G3 gas technician license from the Technical Standards & Safety Authority. You can verify their license status directly on the TSSA website by searching their license number or company name. A legitimate contractor will readily provide their TSSA license number - if they hesitate or can't provide it, that's a major red flag.

WSIB Coverage protects you from liability if a worker is injured on your property. Ask to see their WSIB clearance certificate, which should be current and list your contractor's business name. You can also verify WSIB coverage online through their website. Additionally, confirm they carry liability insurance - reputable contractors typically carry $1-2 million in coverage.

In Ottawa, you should also verify the contractor is registered with the City of Ottawa if required for permits. For major installations like furnaces or gas fireplaces, proper permits must be pulled through the city and inspected by TSSA. A licensed contractor will handle this process and provide you with copies of all permits and inspection certificates.

Red flags to avoid: contractors who work only for cash, can't provide license numbers, offer door-to-door services, or pressure you to sign immediately. Always get multiple quotes and verify credentials before any work begins.
