Environment Canada has issued a smog warning for much of the Montreal metropolitan area as a thick haze covers the city. "High concentration of pollutants are expected and will result in poor air quality, especially in urban areas where pollutant emissions are higher," the agency states in its alert. "Fine particulate concentrations are high over the Greater Montreal area and will remain that way overnight and possibly into Sunday. Poor air quality may extend into other regions."
The affected areas include:
the Châteauguay – La Prairie area;
the Laval area;
the Longueuil – Varennes area;
and Montreal Island area.
Smog can result in adverse health effects for children with asthma and people with heart conditions. "It is therefore recommended that these individuals avoid intense physical activity outdoors until the smog warning is lifted."
A high volume of car traffic contributes to the accumulation of smog. Montrealers can help better the air quality by opting for public transit.
"In Quebec," however, "wood heating is the main source of fine particles that contribute to smog during winter. This activity generates the largest number of these particulates, more than industrial activities and transportation," says Environment Canada.
On Twitter, the City of Montreal reminded residents that the use of appliances and fireplaces, including wood and pellet stoves, that "make use of solid fuel" is forbidden during smog warnings.
