Toronto is experiencing some of the worst air quality globally today due to wildfire smoke drifting in from northern Ontario and the Prairies. According to global tracker IQAir, the city ranked among the most polluted major cities worldwide.
Environment Canada has issued a special air quality statement across the GTA, warning of a “very high risk” on the Air Quality Health Index. Residents are advised to limit outdoor activity and consider wearing an N95 mask if outside is unavoidable.
Common symptoms from smoke exposure include eye and throat irritation, headaches, and coughing. Those with respiratory conditions, young children, seniors, and pregnant individuals are most at risk.
The Toronto District School Board (TDSB) is monitoring the situation, with some schools moving recess and physical activity indoors. HEPA filters are being used where possible.
Conditions are expected to improve slightly by evening but may remain poor into early next week.
