Wildfire smoke from Canada and Minnesota creates unhealthy air quality across the Midwest and Northeast United States.

Wildfire smoke from active blazes in Canada and northeastern Minnesota has significantly deteriorated air quality across a broad swath of the Midwest and Northeast. The administration announced that the smoke, driven by hot and dry conditions, has pushed ozone pollution into "unhealthy" and "hazardous" ranges for many urban centers, including Chicago, Detroit, New York, and Washington D.C. While some regions, such as Chicago, saw a slight improvement in air quality over the weekend, many areas remain under alerts. Officials are warning that the smoke contains harmful pollutants that can cause lasting health effects, particularly for children, older adults, and those with respiratory conditions like asthma. To mitigate the impact, experts recommend staying indoors, using air purifiers, and wearing masks when necessary. The smoke is expected to persist for at least a week, with shifting winds on Monday providing some relief. In response to the persistent haze, President Trump blamed Canada's forest management for the smoke and threatened to impose additional tariffs on the country.
