What does all this wildfire smoke in southern Quebec mean for your health?
CBC
Much of southern Quebec, including the Montreal region, is draped in a hazy cloud of smog as massive forest fires continue to burn in northern sectors of the province.
Experts say this can have an effect on your health, especially if you're already vulnerable.
Dr. Shawn Aaron, a professor in the department of medicine at the University of Ottawa, recommends wearing an N95 mask if you must work outdoors.
"Ideally on days like today, you should stay inside with the windows closed and the air conditioning on," he said in a statement.
"If you have HEPA filters in your house, turn them on. Avoid exercising or heavy work outdoors on poor air quality days."
According to Environment and Climate Change Canada (ECCC), which has issued a smog warning for Montreal and other regions Tuesday, the poor air quality especially affects asthmatic children and people with respiratory ailments or heart disease.
Overall, ECCC recommends staying inside if you feel unwell or are experiencing shortness of breath, wheezing, or an asthma attack, and contacting your care provider.
Aaron said babies, young children and the elderly are particularly vulnerable.
In Laval, Que., Dr. Jean-Pierre Trépanier, who heads public health for the city, said those who are pregnant should also use caution.
His agency, CISSS de Laval, encouraged school boards and service centres to keep children indoors Monday afternoon and all day Tuesday. The school boards agreed.
"We wanted to get kids away from the small particles," he said. "It's quite an uncommon event. It's the first time I've recommended that in 15 years of practice."
There is poor air quality from the Quebec City region all the way to Gatineau.
The Eastern Townships have acceptable air quality, and so do areas farther north like Lac-Saint-Jean and Saguenay.
But the poor air quality is extending westward and even south of the border. Ottawa's air quality is considered dangerous to human health and is expected to stay that way through most of the week.
