OTTAWA, May 30 (Xinhua) -- Wildfire smoke has triggered air quality alerts in six provinces and territories across Canada, according to Environment Canada's weather information published on Friday.
The agency issued air quality alerts in two neighboring provinces, Saskatchewan and Manitoba, where states of emergency were declared one day apart.
Saskatchewan Premier Scott Moe declared a 30-day provincial state of emergency on Thursday, saying that at least 15 communities, mostly in the northern region, have been evacuated. Over 40 structures have been destroyed, he added.
His Manitoban counterpart, Wab Kinew, did the same on Wednesday, while issuing mandatory orders to evacuate about 17,000 people.
"Smoke is causing very poor air quality and reduced visibility. As smoke levels increase, health risks increase," Environment Canada warned.
"Limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events," it said, urging those in affected areas to keep windows and doors closed, use air filters inside, and wear a mask when outdoors.
Warm and dry conditions continue to support wildfire activity as the weekend approaches. The smoke will linger for a prolonged period near the source region of the fires, it said. ■
