Smog warning

Environment Canada says that the air quality will be poorest in metropolitan areas where there are higher levels of pollution.

Children with asthma as well as people with respiratory ailments or heart disease are being encouraged to avoid intense physical activity outdoors until the warning is lifted.

Environment Canada says wood heating is the main source of particles that contribute to smog in the winter, surpassing industrial activities and transportation.

In Montreal, it’s prohibited to use a wood or solid-fuel burning appliance unless it emits fewer than 2.5 grams of particles per hour.

It’s prohibited to use even certified wood stoves or solid fuel appliances during smog warnings, and those who disregard the rule can be fined.

Environment Canada says that a major weather system from the Southern United States will reach Quebec on Sunday.

Up to 2 millimetres is expected to fall starting Saturday afternoon into Sunday morning.

Precipitation intensity may vary throughout this period, but the weather agency says it will be enough to make surfaces slippery.

Environment Canada says highways, roads and walkways may be icy and urge motorists to slow down.

“Pooling of water may occur on roads or in low-lying areas.”
