Toronto will once again see diminished air quality on Tuesday as smoke from forest fires in other regions drift into the city.
A special air quality statement has now ended but Toronto’s air quality was among some of the worst in the world on Tuesday morning.
According to Swiss air quality tracker IQAir, Toronto’s air quality was ranked 6th worst in the world early Tuesday morning.

Toronto will also see a return of humid weather on Tuesday, with a daytime high of 29 C, feeling closer to 34 with the humidity.
The national weather agency previously said GTA residents may experience some unpleasant symptoms as a result of the smoke, including eye, nose, and throat irritation, as well as headaches or a mild cough.
Environment Canada said more serious symptoms, which are less common, include wheezing, chest pains or severe cough.
Those who are more likely to be impacted by poor air quality include older individuals, pregnant people, young children, people with chronic health conditions, and those who work outdoors.
CP24 Meteorologist Bill Coulter said hot and “mostly dry” weather is in the forecast for the start of the work week.
“Smoke from forest fires has been reducing air quality over the last few days,” he said.
“That air quality is gradually improving and will continue to improve as winds sift to tap into hot and humid air from the (United States) and cuts off the flow of smoky air from northern areas.”
