An EPA-certified wood fireplace is an appliance that meets the Environmental Protection Agency’s emission standard of 2.5 g/h of fine particles or less. In Quebec, this certification is not a marketing detail: in Montreal, only EPA- or CSA-certified appliances can be used. Beyond the law, these appliances heat better and consume up to 50% less wood. Here is what the certification means, why it is mandatory, and how to verify that your fireplace is compliant.
What is an EPA-certified wood fireplace?
It is an appliance tested and approved according to the American EPA NSPS 2020 standard, in effect since May 15, 2020. The threshold is 2.0 g/h of fine particles in the crib wood test, or 2.5 g/h in the log test. In Quebec, the Canadian CSA B415.1 certification is recognized as equivalent.
Concretely, the certification guarantees that the appliance burns cleanly, thanks to secondary combustion that consumes the gases and particles that once went up in smoke. This is what distinguishes a modern appliance from an old, energy-hungry stove.
Why is EPA certification mandatory in Quebec?
Because fine particles from old appliances harm air quality, especially in winter. On the territory of the City of Montreal, a solid fuel appliance can only be used if it is EPA or CSA certified and emits 2.5 g/h or less, and this has been the case since October 1, 2018. In Laval, by-law L-12792 prohibits appliances exceeding 7.5 g/h without certification.
The impact is concrete: an open masonry fireplace emits around 100 g/h of fine particles, compared to less than 2.5 g/h for a certified appliance, a reduction of over 97%. For details on rules by city, see our guide on wood fireplace regulations in Montreal and Laval.
What are the concrete benefits of a certified appliance?
Beyond compliance, certification translates into real daily gains. A recent certified appliance extracts more heat from each log and creates less chimney buildup.
- Up to 50% less wood for superior heat
- Emissions under 2.5 g/h, compared to about 100 g/h for an open fireplace
- Less creosote, meaning a cleaner and safer chimney
- Compliance with municipal regulations and peace of mind for your insurance
- A certified insert cuts cold air infiltration by up to 85% when turned off
How to check if your wood fireplace is certified?
Three checks are enough. Locate the rating plate on the back of the appliance, where a certified appliance displays its emission rating and EPA or CSA certification. Then consult the EPA’s public list of certified appliances. Finally, if in doubt, especially for an appliance purchased before 2010, have compliance confirmed during an inspection.
Most old slow-combustion stoves from before the 2000s do not meet current thresholds. If no emission rating appears, consider the appliance likely non-compliant.
What to do if your fireplace is not certified?
You can replace it with an EPA-certified appliance, install an insert in your existing masonry, convert to gas, or opt for an electric fireplace. The right choice depends on your attachment to wood fires and the condition of your chimney. Our detailed guide explains how to replace an old wood stove in Montreal.

In the field: a certified appliance in a Laval home
In Laval, a family replaced an old non-certified stove, which had become prohibited to use and was wood-hungry. Our Technical Project Managers installed an EPA-certified wood stove sized for the space. Wood consumption dropped, the house heats better, and the family was able to submit their proof of certification for the Laval municipal grant of up to $1,000.
