In St. Catharines, Ontario, property owners must ensure gas lines and connected appliances are safe and inspected by a licensed gas technician. Book inspections before placing a property on the market, after alterations, or when a fuel-burning appliance is installed or suspected of leaking. The City’s Building Services explains permit requirements for fuel-burning appliances and gas work, while the provincial regulator TSSA oversees technical safety and licensed trades. Building permit info[1] and TSSA fuel safety guidance[2] are the primary official sources for owners in St. Catharines.
