Toronto’s Air Quality Plummets to Worst Globally as Canadian Wildfire Smoke Chokes City and Threatens U.S.

Toronto has seen its air quality rank as the worst among major cities worldwide on Wednesday, primarily due to smoke from wildfires in northwestern Ontario. This environmental crisis has darkened skies and extended its reach into the northeastern United States, leading to health warnings and advisories for residents to limit outdoor activities.

Wildfires and Their Impact

Wildfires are currently raging in sparsely populated regions hundreds of miles from Toronto, releasing smoke that affects a broad area. Although these fires do not pose a direct threat to urban centers, their impact on air quality is significant. Environment Canada reported an Air Quality Health Index reading of 10+, categorized as “very high risk,” for Toronto. Forecasts indicate that these hazardous conditions may persist through Thursday night.

In New York City, the effects of the smoke have been felt for several days, particularly as New Jersey prepares to host the World Cup final on Sunday. Local authorities have issued alerts as air quality levels reached unhealthy thresholds, advising residents to minimize strenuous outdoor activities and take frequent breaks if they must be outside.

The National Weather Service has indicated that smoke could linger into the latter part of the week. Dan Westervelt, an associate research professor at Columbia University, noted that the worst effects may still be ahead for New York City and surrounding regions, including the Great Lakes and New England.

Global Air Quality Rankings

According to IQAir, a Swiss air quality technology company, Toronto has surpassed Kinshasa and Delhi to become the city with the worst air quality globally. New York City ranks fifth in this troubling list, highlighting the widespread impact of the wildfires.

The situation has also led to alarming incidents, including the entrapment of two small groups of children from Minnesota who were on a camping trip organized by the YMCA in the Canadian wilderness. Reports indicate that one group was evacuated by helicopter in coordination with the Canadian military, with Minnesota Governor Tim Walz confirming that both groups have been rescued and are safely returning home.

Ongoing Wildfire Threats

Wildfire smoke from northern Canada has become a recurring issue during summer months across extensive areas of the United States in recent years. A viral video showcased a Canadian National train surrounded by flames near Armstrong, Ontario, prompting the evacuation of employees and residents in the area. The railroad operator has since suspended rail operations near Armstrong, located over 500 kilometers north of Toronto, as a precautionary measure.

In response to the deteriorating air quality, the City of Toronto has canceled the FIFA Fan Festival and the England-Argentina World Cup watch party at Nathan Phillips Square.

In the New York City area, over 80,000 attendees are expected at the World Cup final in an open-air stadium in New Jersey, while another 50,000 plan to watch the game from Central Park in Manhattan, where the skies have appeared hazy.

New York Governor Kathy Hochul has acknowledged the unhealthy air conditions across the state, urging residents, particularly those with pre-existing health conditions, to exercise caution.

Current Wildfire Statistics

The Government of Canada has reported that the wildfire season in 2026 has started more slowly than in the previous two years, which were among the worst for wildfires. However, officials have warned that the likelihood of fires remains high due to warmer-than-usual temperatures across the country. As of Wednesday, approximately 835 active fires were burning, with 112 classified as out of control. To date, 1.9 million hectares have burned, predominantly in the central provinces of Manitoba, Saskatchewan, and Ontario.

Greg Evans, a professor of chemical engineering and applied chemistry at the University of Toronto, remarked that Toronto is currently facing a dual threat of severe heat and wildfire smoke. He anticipates that such occurrences will become more frequent in the coming decades, necessitating that cities and residents prepare for these challenges.

Toronto resident Paula Oreskovich expressed concern over the haze and smell of smoke she noticed when stepping outside. She emphasized the importance of acknowledging climate change, stating that it is a global issue that cannot be ignored.
