Heating with wood is among the leading causes of winter smog. Limiting the emission of particles into the atmosphere thus promotes better air quality and helps improve public health in Montréal. For this reason, residents are required to comply with this by-law. Those who do not will be liable to fines.

Solid fuel-burning appliances

Solid fuel-burning appliances include  stoves or fireplaces designed to burn wood logs or any other solid materials, such as ecological logs, pellets or coal. 

A gas or electric fireplace is not a solid-fuel burning appliance.

Mandatory certification

It is now prohibited to use a solid fuel-burning appliance unless it emits fewer than 2.5 grams of particles per hour, regardless of the fuel used. 

This emission rate must:

• be certified by the Environmental Protection Agency ( EPA)
• or be compliant with Canadian standard CSA/B415.1-10

Please ensure that the technical specifications for your appliance mention one of these certifications and the number of grams emitted per hour.
