## Summary

More than 800 wildfires ignited across [Canada](/en/entity/canada) from July 13, with major fires exploding in far northern Minnesota and western Ontario and sending massive smoke plumes south into the United States. By July 16, the smoke was driving air quality index readings above 1,000 in Marquette, Michigan and above 680 in Duluth, Minnesota; hazardous conditions start at an AQI of 300. More than 120 million people across the [US](/en/entity/united-states) Great Lakes region and northeastern states faced poor to hazardous air conditions, with weather models forecasting the smoke to persist through at least Saturday July 18. New York City issued air quality alerts with visible haze spreading across the tri-state area. Canada's 2026 fire season started slowly but accelerated sharply in mid-July.

## Why it matters

AQI readings above 300 are classified as hazardous; parts of Michigan and Minnesota recorded more than three times that level. The smoke compounds heat-related health risks for communities without air conditioning and is expected to strain hospital emergency departments across the Northeast with respiratory complaints, as smoke from Canadian fires increasingly affects US population centers.

## What to watch

- When weather patterns shift to clear the smoke from the northeastern US
- Whether AQI readings in major cities including New York, Boston and Chicago remain hazardous
- Canada's ability to mobilise firefighting resources for 800+ concurrent fires
