Smoke from over 100 active wildfires in northern Ontario has earned Toronto the dubious honor of having the worst air quality in the world, according to IQAir, the Swiss company that ranks such things. Environment Canada issued health warnings Wednesday as the city's sky turned a sickly yellow, reminiscent of a sepia filter no one asked for.

The city is also enduring a heatwave that shattered a three-decade record, hitting 37.3°C downtown, with runways at Pearson International Airport reaching a toasty 55°C. Because why not add a heatwave to the smoke?

The wildfires have forced mandatory evacuations from several First Nations communities. A train crew near Armstrong, Ontario, captured harrowing video of flames whipping past windows. “This could potentially overtake us here … This has gotten a little scary,” a crew member noted, understating the situation. Canadian National Railway confirmed the crew was safely evacuated.

Images showed families fleeing by boat as massive smoke plumes loomed. “My family hometown, Collins Ontario, is GONE,” photographer Nadya Kwandibens posted. Residents of Namaygoosisagagun First Nation said they had only minutes to escape across Collins Lake.

“What we are witnessing right now is devastating,” said Sol Mamakwa, a member of the Ontario New Democratic Party. “An entire First Nation community has been erased.” Lise Vaugeois, the regional provincial representative, added, “Collins has burned to the ground. … Fires are part of a natural cycle, but the extreme temperatures … are indicators of climate change.”

Air quality alerts have also been issued in Michigan, Minnesota, and Wisconsin, with thicker smoke expected to drift over New York, Washington, and other eastern seaboard cities later in the week. Because sharing is caring.
