Environment Canada has extended its Special Air Quality Statement for most of southern and eastern Ontario.

It’s due to more than 100 fires burning in Quebec.

While the GTHA’s air quality rating was sitting at a low-to-moderate risk as of this morning, air quality is expected to worsen in the coming hours and days, expected to reach High Risk territory by tomorrow.

Alerts are out in various other parts of the country as more than 400 wildfires are burning across Canada.

Officials say people with lung disease (such as asthma) or heart disease, older adults, children, pregnant people, and people who work outdoors are at higher risk of experiencing health effects caused by wildfire smoke.

It’s recommended that you stop outdoor activities and contact your health care provider if you or someone in your care experiences shortness of breath, wheezing (including asthma attacks), severe cough, dizziness or chest pains.
