The City of Westmount has adopted a new by-law restricting the use of wood-burning appliances on its territory. The by-law targets the use of wood-burning fireplaces and is in line with the mission of the Eco-responsible Westmount Initiative and our desire to be part of the solution to the climate crisis.
As of September 1st, 2024, it will be forbidden to install or use any heating or cooking appliance or fireplace that uses solid fuel (e.g. wood-burning stove or fireplace, new or pre-existing) in all Westmount’s residential buildings, unless the appliance has an emission rate equal to or less than 2.5 grams of fine particles per hour into the atmosphere. The appliance must be certified for its emission rate by at least one of the following:
Important :
Solid-fuel-burning appliances are devices that burn solid materials, such as wood, coal, pellets, or other biomass, to generate heat for various purposes. These appliances are commonly used for residential heating, including wood stoves, pellet stoves, coal stoves, and masonry heaters. The heat produced by burning these solid fuels can be used to warm the living spaces in a building or for cooking.
All owners of solid-fuel-burning appliances or fireplaces, whether or not their appliance comply with the new by-law, must inform the City within 120 days of the by-law coming into force (i.e. before December 30, 2023) by filling out a declaration form. This declaration form can be filled out online, or can be printed and delivered in person to the Urban Planning Department at city hall (4333 Rue Sherbrooke Ouest).
Owners planning to replace a non-compliant solid fuel appliance or fireplace with one that complies with the new regulations must :

Residential wood burning is the main source of fine particle emissions in Quebec, especially in winter. These particles are associated with respiratory and heart problems, and even premature death, since the World Health Organisation (WHO) has confirmed that the fine particles produced by fireplaces are carcinogens. Furthermore, one of the main sources of winter smog in Quebec is directly linked to burning wood. In 2020 in Montreal, 9 of the 10 smog days linked to ozone and fine particles in the air occurred in winter, the period when wood burning is most common.
The City of Westmount is joining the movement already undertaken by several cities to try to slow down the pollution caused by the use of solid-fuel appliances, as is the case for the City of Montreal, which since 2018 has banned the use of wood-burning stoves and fireplaces that emit more than 2.5 grams of fine particles per hour. Appliances built before 1990 can emit an average of 60 to 100 grams of fine particles per hour into the atmosphere.
If you don’t use your wood-burning fireplace, you don’t have to do anything: you don’t have to complete the declaration or change your fireplace. You can keep your fireplace as it is.
No, electric, propane and natural gas fireplaces are not affected by the new by-law: you don’t have to complete the declaration or change your fireplace. You can keep your fireplace as it is.
No, eco logs do not meet the requirements of the by-law, so certification of your appliance is mandatory.
Yes, but it will have to be declared and modified to comply by September 1, 2024.
All wood-burning fireplaces that are not declared may no longer be used after September 1, 2024. After that date, the use of a non-compliant fireplace is punishable by a fine of up to $4,000.
To be compliant, the fireplace must have a certification that guarantees an emission rate equal to or less than 2.5 grams of fine particles per hour into the atmosphere. This certificate is issued by the professional, and the city will ensure that the wood-burning fireplace is compliant by noting a valid certification on the appliance.
A non-compliant wood-burning fireplace can only be used in the event of a power cut lasting more than 3 hours.
