Are Canadian wildfires under control? Here's what to know.

The thick smoke and haze that turned the New York City skyline orange and brought some of the worst air quality levels the Northeast has seen in decades was spawned by a series of wildfires burning in Canada. 

The fires, which began in early June and have affected Ontario and Quebec, have impacted Canadians and Americans alike. Canadian media reported that 14,000 people in Quebec were evacuated earlier in June. In Canada, the fires caused thick smoke that led to air quality warnings. In the Northeast, there was a similar effect: Cities like New York and Philadelphia were blanketed in a thick haze that eventually traveled south to Baltimore and Washington, D.C. 

The smoke is expected to gradually blow away from the U.S. East Coast over the weekend, but the fires in Canada are still burning. Here's what to know about the ongoing wildfires.
