Plenty of Canadian homes — rural properties especially, but plenty of city homes too — have a wood stove, a wood-burning fireplace insert, or a wood furnace. WETT (Wood Energy Technology Transfer) is the national training standard for these appliances, and a WETT-certified technician assesses clearances, installation, and chimney condition against code before issuing certification.

The quick answer
Plenty of Canadian homes — rural properties especially, but plenty of city homes too — have a wood stove, a wood-burning fireplace insert, or a wood furnace. WETT (Wood Energy Technology Transfer) is the national training standard for these appliances, and a WETT-certified technician assesses clearances, installation, and chimney condition against code before issuing certification.
Most Canadian home insurers will not bind or renew a policy on a home with a wood-burning appliance without current WETT certification confirming it's installed safely — no certification can mean a declined policy, or a denied claim if there's ever a fire. This is a real fire and carbon-monoxide safety question, not a paperwork formality.
How to spot it
A wood stove, insert, or free-standing wood furnace visible in listing photos; a second chimney or flue that isn't serving the furnace; ask the seller for the current WETT certificate and its date — certifications are typically only valid for a set period and need periodic renewal.
What it costs
A basic WETT Level 1 (visual) certification visit runs roughly $200–$300; a more thorough Level 2 or 3 assessment — looking at hidden chimney or attic areas, or requiring some disassembly — can run $500+. If clearances or the installation itself don't meet code, remediation cost depends entirely on what has to move or be rebuilt.
What to do
Confirm with your insurance broker, before removing conditions, whether the appliance needs a fresh WETT certification to bind coverage — and budget for it if the seller doesn't have a current one. Don't assume an old certificate, or "it's been there for years," satisfies a new insurer.
Education and triage, not a home inspection. Casaroo flags a wood-burning appliance from your photos; a WETT-certified technician confirms the installation meets code and issues or renews certification. We flag; we don't inspect.
