How much does it cost to install a commercial-grade grease duct for a Toronto restaurant kitchen?

Commercial grease duct installation in Toronto typically runs $8,000–$25,000+ depending on the length of the run, the number of access panels, fire suppression integration, and whether the shaft needs to be built through multiple floors. This is highly specialized work that sits at the intersection of sheet metal fabrication, fire code compliance, and commercial kitchen design — and it's a different animal from residential ductwork.

That said, commercial kitchen exhaust is outside the scope of what Toronto Ductwork and our residential contractor network covers. We match GTA homeowners with ductwork and ventilation professionals for residential projects — things like home kitchen range hood exhaust, bathroom ventilation, HRV/ERV systems, dryer vents, and complete residential duct systems.

For Your Commercial Project, Here's Where to Turn

Commercial grease duct work in Toronto falls under the Ontario Fire Code (O. Reg. 213/07), NFPA 96 (Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations), and the City of Toronto Building Code requirements for commercial occupancies. You'll need a contractor who specifically works in commercial kitchen exhaust — they'll handle:

• UL 1978-listed grease duct fabrication (all-welded stainless steel or carbon steel with liquid-tight continuous external welds)
• Clearance-to-combustibles requirements (typically 18 inches, or zero-clearance with listed enclosures)
• Access panel placement every 12 feet and at every change of direction
• Integration with Ansul or equivalent fire suppression systems
• City of Toronto mechanical and fire permits

Finding the Right Contractor

For commercial kitchen exhaust, you want a sheet metal contractor with specific NFPA 96 experience and commercial kitchen references. Ask to see past restaurant projects, verify WSIB coverage, and confirm they pull the required City of Toronto mechanical permits. The Toronto Construction Network connects contractors across multiple commercial trades — you can explore the broader directory at torontoconstructionnetwork.com to find sheet metal and mechanical contractors working in the commercial space.

For any residential ductwork needs — including a home kitchen range hood exhaust that requires make-up air, or any other ventilation project at a residence — Toronto Ductwork is happy to help match you with the right local professional.
