Wildfire events are increasing across Canada as the climate changes, resulting in more days with poor air quality. Wildfires emit harmful pollutants such as fine particulate matter (PM2.5) and volatile organic compounds, which can infiltrate into indoor environments.  Breathing wildfire smoke is harmful to health, leading to respiratory issues and exacerbation of conditions like asthma. Children are particularly susceptible.  Schools and child care settings play an important role to reduce children’s exposure to wildfire smoke by monitoring the local Air Quality Health Index, reducing time outdoors based on local air quality and students’ health conditions, and following public health and expert guidance on maintaining indoor air quality.
