Tracking the 2026 wildfires in Canada

Where they are, how much has burned and how they're affecting air quality

Following three years of historic wildfire destruction, this season is shaping up to be another tough one.

Despite healthy spring rainfall, forecasted intense summer heat and lower-than-normal rainfall in the summer months is driving up fire danger across the country.

Here is where the wildfire situation stands today.

Fire danger across Canada is calculated by taking into account several factors including temperature, humidity, wind speed and rain.

Among other things, type of rating helps authorities decide how to best manage existing fires and when to implement burn bans.

Smoke from active Canadian wildfires doesn't just affect local communities. It can waft into the most populated areas of Canada.

The wind can also carry it across the border into the eastern seaboard of the United States, impacting major metropolitan hubs such as New York City.

Smoke from so many wildfires can pose significant health risks. On the Air Quality Health Index, anything seven or higher is considered high risk. The general population (regardless of any pre-existing medical issue) should consider avoiding strenuous activities outdoors at that rating.

Those living in areas with higher AQHI ratings may consider wearing a face mask if they go outside to protect against fine particles in smoke. According to Environment Canada, when indoors it’s important to keep all windows and doors closed as much as possible.
