Smog Warning In Southern Quebec
Places along the lower St. Lawrence River will see smog persist through the morning.
Wood heating is the main source of smog in Quebec during the winter months.
Air quality can be improved by limiting the use of fireplaces and wood-burning stoves, opting to use public transit, reducing our driving speed and not letting our car engines idle unnecessarily.
Those who are asthmatic or have respiratory ailments or heart disease should limit their time outside.
