A milky hazy has enveloped Toronto, prompting Environment Canada to issue a special air quality statement for the city. Smoke from forest fires in the northwestern part of the province is now hanging over southern Ontario, and it has lowered air quality and reduced visibility. "High levels of air pollution due to smoke from ongoing forest fires are possible," Environment Canada said. When the smoke descends to ground level, air quality can deteriorate and visibility can be reduced, the federal agency added. Air quality is expected to improve on Tuesday when a cold front passes over the region.
