Much of the Northwest is under a Special Air Quality Statement because of the forest fires.
Environment Canada warns that smoke will continue to spread eastward today, reaching as far as Wawa by tonight.
The smoke is leading to poor air quality and reduced visibility.
The weather service says wildfire smoke can contain many harmful chemicals, so you should consider reducing the time you are exposed to it.
People may experience symptoms like increased coughing, throat irritation, headaches or shortness of breath. Children, seniors, and those with heart or lung disease, such as asthma, are especially at risk.
