A man rides an electric scooter as haze from wildfire smoke is visible in Toronto, Ontario, Canada, on June 06, 2025. Toronto's air quality ranks among the worst in the world today as smoke from wildfires burning in Manitoba, Saskatchewan, and Alberta drifts into the region. Toronto's air quality is currently the second most polluted major city in the world, according to a ranking by IQAir, a Swiss air quality technology company. This places it below Santiago, Chile, and above Montreal, which ranks third as it also experiences wildfire smoke from western provinces. Environment Canada urges residents to limit their time spent outdoors and suggests that people consider reducing or rescheduling outdoor sports, activities, and events. Environment Canada notes that smoke may cause mild irritation to the eyes, nose, and throat, and may lead to headaches or a mild cough, as well as wheezing, chest pains, or a severe cough.
