Environment Canada has issued a Special Air Quality Statement for Toronto, warning that drifting wildfire smoke is expected to cause poor air quality and reduced visibility throughout the day.

An air quality statement is in effect for Toronto and the surrounding region as wildfire smoke continues to drift south, Environment Canada says.

Ottawa and much of south and southeastern Ontario can expect poor air quality this weekend as wildfire smoke returns, Environment Canada says. The special air quality statement was issued shortly before 1:30 p.
