Air quality suffers as crews battle over 180 Ontario wildfires

VIDEO: It was another day of weather warnings for people in Ontario, as a result of out-of-control wildfires. But Toronto no longer has the worst air quality in the world. The smoke is being carried further south, and Detroit, Michigan crossed into the “hazardous” range today. Meanwhile, winds from the northwest are fanning the flames of dozens of forest fires in northern Ontario, prompting even more evacuations there. Tessa Bennett reports.
