# Wildfire smoke turns Toronto's sky orange and its air among the world's worst

Smoke drifting from wildfires in northern Ontario has blanketed Toronto in an orange haze and given Canada's largest city some of the worst air quality in the world, prompting official warnings, pool closures and the cancellation of a World Cup fan event.

A thick pall of wildfire smoke has settled over Toronto, turning the sky an eerie orange and pushing the city's air quality to among the worst of any major city on Earth.

The smoke has drifted south from wildfires burning in northern Ontario, hundreds of kilometres away, blanketing the Greater Toronto Area and much of southern Ontario in haze, [as Al Jazeera reported](https://www.aljazeera.com/video/newsfeed/2026/7/16/wildfire-smoke-engulfs-toronto-canada-and-turns-its-skies-orange). At the height of the episode, Toronto ranked at or near the top of global air-pollution rankings, above cities more usually associated with dirty air such as Delhi and Kinshasa.

## Warnings and closures

Environment Canada issued an air-quality warning for the region, with the poor conditions setting in from Tuesday night and forecast to persist into Friday. Officials urged residents to limit time outdoors, and warned that children, older people, pregnant women and those with heart or lung conditions were most at risk of symptoms ranging from irritated eyes and throats to coughing and chest discomfort.

The city took visible precautions. Outdoor municipal swimming pools were closed, and an event tied to the World Cup fan festival was called off because of the smoke. Health authorities advised people to keep windows shut and to use air filtration indoors where possible.

## A harsh fire season

The episode is the latest sign of a punishing wildfire season across Canada. Smoke from the fires has affected not only Ontario but also neighbouring Quebec and has drifted into parts of the northern United States, a reminder of how far the effects of large blazes travel. In recent years Canadian wildfire smoke has repeatedly degraded air quality across eastern North America, at times shrouding cities hundreds or thousands of kilometres from the flames.

Scientists link the trend to climate change, which is lengthening fire seasons and creating hotter, drier conditions that help fires start more easily and burn more fiercely. The result, increasingly, is that the consequences of wildfires are felt not just in remote forests but in dense urban centres far away, where residents wake to orange skies and are told to stay indoors.

For now, Torontonians have been left waiting for a change in the wind. Forecasters suggested the haze could begin to lift later in the week, but until then the city faces the surreal experience of a sun dimmed to a dull disc behind a curtain of distant smoke.
