Why this article stays high-level
Furnace, AC, heat pump, and water heater work can involve gas, electrical, or building permits depending on the scope and municipality. Requirements differ across Toronto, York Region cities (including Richmond Hill), Peel, Durham, and others.
Comfort HVAC will not invent a single GTA-wide rule. Always verify with your municipality or a licensed contractor who will pull required permits for the job.
