A stretch of southern Ontario remains under a special air quality statement today amid smoke from wildfires burning in parts of the country. Environment Canada says smoke from forest fires can cause reduced air quality and visibility that can fluctuate throughout the day.

The wildfire smoke may persist through today (Tuesday) and possibly Wednesday,” said Environment Canada in a Tuesday morning statement.

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.
