Does my Ottawa home insurance require a WETT certificate before covering a wood-burning fireplace or stove?

Yes — virtually every home insurance company operating in Ottawa now requires a WETT inspection and certificate before they will insure a home with a wood-burning fireplace, wood stove, or wood-burning fireplace insert. This has become the de facto standard across Ontario over the past decade, and failure to obtain WETT certification before operating a wood-burning appliance is one of the fastest ways to have a claim denied or your policy cancelled entirely.

Why Ottawa Insurers Require WETT Certification

Insurance companies view wood-burning appliances as higher-risk than gas or electric fireplaces because improper installation, maintenance, or operation can lead to chimney fires, carbon monoxide poisoning, structural damage, and house fires. A WETT inspection—which examines the appliance itself, the entire chimney system, clearances to combustible materials, hearth protection, and overall safety—gives insurers confidence that the installation meets national safety standards. In Ottawa's extreme climate, where freeze-thaw cycling and prolonged burning seasons create heightened risks, insurers take this requirement very seriously.

The WETT certification is not a one-time thing after installation. Many insurers require a current Level 1 WETT inspection annually, especially if the fireplace or stove is actively used as a supplemental heat source. A Level 1 inspection costs $250 to $450 in Ottawa and takes about an hour — a WETT-certified inspector visually examines the appliance, chimney condition, creosote accumulation, and clearances, then issues a formal report that you provide to your insurer.

What Happens Without WETT Certification

Operating a wood-burning fireplace or stove without WETT certification creates serious consequences. If your home experiences a chimney fire, structural damage from a chimney fire, or a fire that starts in or near the fireplace, your insurance claim will almost certainly be denied because you operated an uninsured appliance. Some insurers will outright cancel your homeowner's policy if they discover you are burning wood without WETT certification, leaving you scrambling to find coverage. This is not theoretical risk — Ottawa insurance brokers regularly encounter claims denials for exactly this reason.

Before buying a home with an existing wood stove or fireplace, always ask the seller for proof of a valid WETT inspection. If the seller cannot provide documentation, budget $300 to $600 for a Level 2 WETT inspection (more thorough than Level 1, appropriate for real estate transactions) before you close on the property. This inspection may reveal that the installation is non-compliant, the chimney is unsafe, or modifications are required to bring the system up to code—information that could save you thousands of dollars and prevent a dangerous situation.

When you install a new wood stove, fireplace insert, or wood-burning fireplace, hire a WETT-certified installer who will perform the installation to WETT standards and provide you with WETT documentation upon completion. This documentation is essential for your insurer. Keep your WETT inspection reports on file — you may need them when renewing your insurance, selling your home, or filing a claim.
