Air Quality
Forest fires in Canada and the United States can have a negative effect on air quality. The smog caused by such fires contains more fine particles than what might be called "normal" smog. The effects caused by exposure to these fine particles vary according to:
- Their level (concentration)
- Exposure time
- Intensity of physical activity
- Presence of health problems
It is difficult to predict the amount of smoke and the direction it takes. Smoke from forest fires can be transported hundreds or thousands of kilometers from the fire zone.

What to Do in Hot Weather
In hot weather, we recommend the use of an air purifier in order to maintain tolerable indoor temperatures (<31°C), despite the smoggy conditions:
- Use an air-conditioner to maintain a comfortable indoor temperature.
- Open windows in the evening and at night to cool the home if no air-conditioning is available.
- Take steps to reduce overheating in the home, (e.g., avoid using the oven and dim incandescent lights).
People most at risk
Poor air quality can affect the health of the entire population, regardless of age. Some people, however, are more at risk:
- People with respiratory disease, heart disease, or diabetes
- Babies and toddlers (0–4 years)
- Pregnant women
- Seniors (65 or older)
Health impacts
Exposure to fine particles from forest-fire smoke or smog may produce mild symptoms:
- Itchy eyes
- Runny nose
- Mild cough
- Sore throat
- Headache
More severe symptoms include:
- Severe cough
- Shortness of breath
- Wheezing
- Dizziness
- Heart palpitations
- Chest pain
In case of symptoms:
- Go inside and stay there.
- Keep asthma medication within easy reach.
- Call Info-Santé 811 or 911 depending on the severity of the symptoms (e.g., chest pain).
- Notify family members, if necessary.
