Environment Canada is warning of poor air quality and reduced visibility in Toronto today due to wildfire smoke that has drifted into the region. An air quality warning, yellow alert, has been issued for the city on Wednesday and the national weather agency as smoke from forest fires in northwestern Ontario drifts south. “Poor air quality may persist into Thursday for some areas,” the national weather agency said in its alert.
“As smoke levels increase, health risks increase. Limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events.”
As of about 6 a.m. on Wednesday, Toronto’s air quality was ranked 3rd worst in the world, according to IQAir, which tracks global air quality data. “You may experience mild and common symptoms such as eye, nose and throat irritation, headaches or a mild cough,” Environment Canada said in its advisory. “More serious but less common symptoms include wheezing, chest pains or severe cough.
If you think you are having a medical emergency, seek immediate medical assistance.” Those at greater risk of health issues related to poor air quality include people over the age of 65, pregnant people, infants and young children, and people with existing illness or chronic health conditions. “When indoors, keep windows and doors closed as much as possible,” the advisory read.
“When there is an extreme heat event occurring with poor air quality, prioritize keeping cool.” A heat alert remains in effect for Toronto today with the mercury rising to 33 C today, feeling closer to 36 with humidity.
