(CNN) — While the air quality has improved across the US since last week, more than 500 fires continue to burn in Canada, and more than half of them are “out of control,” according to the Canadian Interagency Forest Fire Centre.
Millions of people from the Midwest to the East Coast have been under air quality alerts in recent weeks as wildfire smoke originating from Canada wafted over major US cities.
More than 20 million acres have been charred by wildfires in Canada so far in 2023 — about three times as much as an average full year.
