Canadian Wildfire Sends Hazardous Smoke Spewing Into US

Officials warned smoke could worsen through the week as 835 fires in Canada sent hazardous air into several U.S. states.

  • On Thursday, July 16, 2026, smoke from hundreds of Canadian wildfires triggered air quality alerts across the US Northeast and Midwest, reducing visibility and increasing concentrations of harmful fine particulate pollution throughout the affected regions.
  • Roughly 850 wildfires are currently burning in Canada, with 112 considered out of control, as hotter, drier conditions driven by climate change have extended fire seasons more than a month longer than 35 years ago.
  • The National Weather Service issued alerts across states including Minnesota and New York, where AQI levels reached 'hazardous' or 'very unhealthy' categories; fine particulate matter can penetrate deep into the lungs and enter the bloodstream.
  • New York City officials expanded emergency measures on Thursday, distributing free KN95 masks; Mayor Zohran Mamdani urged residents to stay inside and limit outdoor activity to avoid exposure.
  • Forecasters expect poor air quality to persist across the Midwest and Northeast through Friday, July 17, 2026, while experts warn that fossil fuel pollution is increasing the likelihood of prolonged smoke seasons beyond 2023 levels.
