Some Montrealers woke up this morning and, thinking they were going to enjoy the heatwave and some sunshine, quickly rushed outside to get some fresh air. However, a thick smog settled over the city on Sunday, June 21. And, Environment Canada issued a notice that warned the people about the Montreal smog.\nOn the Government of Canada's website, it reads "high concentrations of fine particulate matter are expected and will result in poor air quality."\nThe smog, which looks like a thick fog, is believed to come from smoke from a bog fire in the Kamouraska region.\nThe fire broke out again yesterday, causing the evacuation of several residents of the region and requiring the support of air tankers.\nFires in Quebec have been rather common lately, including a massive forest fire recently began in the Lac-Saint-Jean region, due to the extreme heat.\nPoor air quality is expected to end by mid-day, according to Environment Canada.\nSo, Montrealers will still get a chance to enjoy the sunshine as the day progresses.\nThe sectors of the metropolitan region concerned by the alert are the Island of Montreal, Châteauguay - La Prairie, Laval and Longueuil - Varennes.\nThe smoke was even smelled by some Montrealers.\nY'a des matins peu glorieux... #smog et odeur de fumée à #Montréal.
