Smoke moves out of much of northwestern Ontario, ending most air-quality statements

A special air quality statement for northwestern Ontario that was prompted by wildfire smoke from the Canadian Prairies has ended. 

The statement was issued by Environment and Climate Change Canada on Sunday and covered much of the region. It was lifted shortly after 6 a.m. Monday in all areas except for some communities east of Thunder Bay, including around the Hearst and Manitouwadge areas. 

There are major fires burning in Manitoba, Alberta and northern British Columbia. 

While wildfire smoke can be harmful to everyone's health, even at low concentrations, those at higher risk include people with lung disease, heart disease, older adults, children, pregnant people, and people who work outdoors, Environment and Climate Change Canada said.

"Mild irritation and discomfort are common, and usually disappear when the smoke clears. Drinking lots of water can help your body cope with the smoke," the statement said.

"Stop or reduce your activity level if breathing becomes uncomfortable or you or someone in your care feel unwell." 

People are encouraged to speak with their health-care providers about smoke-related risks. They are also urged to develop management plans for smoke events and to have a supply of necessary medications on hand during wildfire season.
