Sky Turned Yellowish... This Country Ravaged by 800 Wildfires Faces 'Worst Air Quality in the World'

Over 800 wildfires have erupted across Canada, spreading hazardous smoke to the northeastern U.S. and severely deteriorating air quality. As of July 15, 835 fires have been reported, with 11,2 considered uncontrolled, burning approximately 1.9 million hectares. Toronto's Air Quality Health Index (AQHI) reached the highest risk level ('10+'), turning the sky yellowish and reducing visibility. The city canceled outdoor events due to poor air quality, while IQAir named Toronto the world's worst city for air quality. Smoke also spread into the U.S., affecting cities like New York, with forecasts predicting air quality impacts in Washington, D.C. Record heat, including Toronto's 37.3°C temperature, has contributed to the fire spread.
