Canada is battling more than 700 active wildfires across the country, roughly two-thirds of which are burning out of control, according to the Canadian Interagency Forest Fire Center (CIFFC). Smoke billowing from the blazes has blanketed central Canada and the northern U.S., prompting widespread air quality alerts.

Every air quality monitor in Minnesota is reporting red or unhealthy conditions for everyone, an official said.

Minnesota's air quality is suffering due to smoke from Canadian wildfires, affecting residents statewide with alerts in place until at least Saturday.
