Reminder: new by-law on solid fuel-burning appliances and fireplaces

To limit the emission of fine particles into the atmosphere, promote better air quality and contribute to fight against climate change, the City of Westmount adopted a new by-law on solid-fuel appliances and fireplaces on August 21, 2023.

In accordance with this by-law, as of September 1, 2024, it will be prohibited to install or use any solid-fuel heating or cooking appliance or fireplace (e.g. wood stove or wood fireplace) in all residential buildings in Westmount, unless the appliance has an emission rate equal to or less than 2.5 grams of fine particles per hour into the atmosphere. This emission rate must be certified by the Canadian standard CSA/B415.1-10 or the American Environmental Protection Agency (EPA) or by Services POLYTESTS. This by-law applies only to residential buildings.

All owners of solid fuel-burning appliances or fireplaces, whether or not they comply with the new regulations, must declare the appliance to the City before December 30, 2023.
