Air quality warnings have been issued for Chilliwack and the Eastern Fraser Valley as wildfires continue to burn across British Columbia, particularly near Boston Bar and the Southern Interior.12

Environment Canada has reported that smoke from these wildfires has led to deteriorating air quality, with concentrations of fine particulate matter reaching levels that could affect health.3

Residents are advised to limit outdoor activities, especially strenuous ones, and to keep indoor air clean by using filtration systems and keeping windows closed.

Those most vulnerable include individuals with heart or lung disease, older adults, infants, children, pregnant individuals, and outdoor workers.

The poor air quality is expected to persist until weather conditions improve.45

Environment Canada has classified the air quality in the region as “high risk”, urging residents to take precautions.

Meanwhile, the wildfire situation in British Columbia remains critical, with approximately 120 fires burning across the province, of which about 50 are classified as out of control.

The chief of the Okanagan Indian Band reported that 230 homes have been destroyed by a wildfire near Vernon, describing the area as looking “like a war zone” after a helicopter tour of the devastation.

As the fires continue to spread, residents are encouraged to seek cleaner air in public spaces if their homes become too smoky or hot.
