The latest numbers on Canada's wildfires and plunging air quality

OTTAWA — Clean Air Day never felt like more of an oxymoron in Canada, as Ontarians and Quebecers whose cities don’t typically smell of campfire reckoned with dangerous levels of woodsmoke billowing down from more than 150 wildfires in Quebec.

On a day Canada's federal government set aside to recognize the importance of healthy air quality, the sun was shrouded by smoke and the breeze carried ash thousands of miles.

Canadians weren't alone. The eastern seaboard of the United States was cloaked in smoggy skies as a massive plume moved south across the border. By midday Wednesday, most residents of central New York state were advised to remain indoors.

Back on Parliament Hill, Prime Minister Justin Trudeau thanked first responders for working to contain hundreds of out-of-control wildfires in seven Canadian provinces and one northern territory. His emergency preparedness minister, Bill Blair, assured the country that every level of government was in lockstep: "It’s all hands on deck and it’s around the clock."

Still, Health Minister Jean-Yves Duclos had a sobering forecast in Ottawa on Wednesday: “We are told by firefighters and other health officials that unfortunately the situation is going to continue for a few more days.”
