Wildfires continue to impact air quality across Western Canada, with conditions expected to worsen today before improving on Thursday. Environment Canada has upgraded its air quality advisory in northern Alberta to reflect deteriorating conditions. Air quality warnings are now in effect for much of the northern part of the province, including communities like Fort McMurray, Fort Chipewyan and High Level, which are experiencing severely reduced air quality and low visibility due to wildfire smoke. “Winds are expected to shift this evening, along with some localized precipitation,” Environment Canada said in its air quality advisory. “As a result there may be some slight improvement in air quality for portions of the region on Thursday.” …Wildfires are also creating hazy conditions further afield, including in southern Saskatchewan and Manitoba, and in Ontario and Quebec from Georgian Bay through Ottawa to Quebec City.
