Smoke from forest fires is impacting air quality in northwestern Ontario.

Environment Canada has put air quality warnings in place for Dryden, Fort Frances, Kenora, and the area north of Kenora.

Meanwhile, special air quality statements are in place for Sioux Lookout, Atikokan, and many First Nations in the northern portion of the region.

The smoke is expected to move into the area on Wednesday, lasting through Thursday for some areas.

As smoke levels increase, health risks increase as well.

Environment Canada is advising that you limit time outdoors.

You may experience mild and common symptoms such as eye, nose and throat irritation, headaches or a mild cough.

Air quality and visibility due to forest fire smoke can fluctuate over short distances and can vary considerably from hour to hour.
