An air quality advisory was issued Monday for Metro Vancouver and the Fraser Valley as winds carry smoke from wildfires burning in B.C.’s interior to the province’s south coast.
It has now been extended through Wednesday.
Wildfire smoke reached ground level in the region by Tuesday morning.
Environment Canada also had several special air quality statements in place for parts of the province.
People with chronic underlying medical conditions are being told to avoid strenuous outdoor activity and contact a health-care provider if they have difficulty breathing, chest pain, discomfort or a sudden cough.
