Air quality warnings lifted for Mississauga, Brampton, Halton and Hamilton

Much-needed relief has arrived across the Greater Toronto Area as air quality warnings have ended following several days of wildfire smoke that forced many residents indoors and disrupted outdoor activities across southern Ontario.

Environment Canada has lifted the air quality warnings for Mississauga, Brampton, Halton and Hamilton as air quality continues to improve.

Toronto and Durham Region had their warnings lifted on Saturday as smoke began to clear. As of Sunday afternoon, the Air Quality Health Index sat at 2 (Low Risk), with conditions considered ideal for outdoor activities.

The improvement comes after a week of deteriorating air quality caused by smoke drifting south from wildfires burning in northwestern Ontario.

At the height of the event on Wednesday, Toronto was ranked as having the worst air quality in the world by IQAir, with smoke blanketing much of southern Ontario.

The smoky conditions also disrupted daily life across the GTA. Municipalities cancelled or modified outdoor programs and temporarily closed some outdoor pools and recreational activities.

In Mississauga and Brampton, some public health clinics also temporarily closed because of the poor air quality.

Although air quality has improved significantly, Environment Canada says conditions can change quickly depending on wildfire activity and shifting winds.

The forecast calls for a moderate risk (AQHI 4) on Sunday afternoon before improving to a low risk in the evening. Moderate risk levels are also forecast for Monday.

While most people can now enjoy their usual outdoor activities, Environment Canada says people at greater risk from air pollution should continue monitoring air quality forecasts and reduce strenuous outdoor activity if smoke returns.

Wildfire smoke can still affect air quality with little warning, and people are encouraged to stay informed by checking local forecasts and air quality updates throughout the week.
