National baseline
The NBC and referenced standards set installation clearance, chimney, and hearth protection requirements.
Canadian building code question
What are the building code requirements for wood stoves and pellet stoves in Canada?
Wood stoves and pellet stoves must meet installation clearance requirements, chimney and venting provisions, hearth protection, and combustion air supply requirements. Installations must comply with CSA and ULC standards referenced in the building code and provincial fire codes.
Solid fuel burning appliances like wood stoves and pellet stoves require careful code compliance covering clearances from combustible materials, chimney construction and height, hearth protection, combustion air supply, and smoke and carbon monoxide detection. The building code references CSA and ULC installation standards that set minimum clearances and protection requirements. Provincial fire codes add inspection and maintenance requirements.
What to check first
- Clearances from combustible materials must meet the appliance listing and referenced CSA/ULC standards.
- Chimneys must be properly sized, constructed, and extend above the roofline to required heights.
- Hearth protection, combustion air supply, and smoke/CO detection are all required.
Jurisdiction notes
Provincial fire code
Provincial fire codes set maintenance, inspection, and operational safety requirements for solid fuel appliances.
Insurance requirements
Home insurance policies may require WETT-certified installation and inspection for wood-burning appliances.
Work through it in this order
- Verify the appliance is listed and labeled to a recognized Canadian standard (CSA or ULC).
- Check installation clearances from combustible materials per the appliance listing and referenced standards.
- Confirm chimney type, size, height above roofline, and clearance requirements.
- Verify hearth protection, combustion air supply, and smoke/CO alarm requirements.
Common questions
Do I need a permit to install a wood stove?
Most municipalities require a building permit for wood stove installation, especially where chimney work is involved.
What is WETT certification?
WETT (Wood Energy Technology Transfer) certification covers the inspection and installation of wood-burning appliances and is often required by insurance companies.
Can I install a wood stove in a basement?
Yes, but basement installations require proper combustion air supply, clearances, and chimney routing through upper floors with appropriate firestopping.
