People living in southern Ontario may notice hazy skies as smoke from fires burning in northwestern Ontario is expected to blow into the area.

Environment Canada issued a yellow air quality warning on Tuesday evening.

“As smoke levels increase, health risks increase. Limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events,” the warning said.

Poor air quality is expected to start Tuesday night and may last through Wednesday.

People affected by the smoke and poor air quality may notice eye, nose and throat irritation, headaches and a mild cough. More serious, but less likely, symptoms include wheezing, chest pains and a severe cough. People over the age of 65, pregnant people, young children and people with pre-existing health concerns are more likely to feel the impacts.

Anyone working outdoors is encouraged to reduce strenuous activities.

“When indoors, keep windows and doors closed as much as possible. When there is an extreme heat event occurring with poor air quality, prioritize keeping cool,” Environment Canada said.
