Metro Vancouver cancelled its air quality advisory for the Lower Mainland on Monday as clean, cool air has pushed smoke out of the region.
The regional district had issued the advisory for Metro Vancouver and the western Fraser Valley due to “high concentrations of fine particulate matter” on Sunday.
Hope and Agassiz had been under an air quality advisory since Aug. 13.
The fine particulate matter was brought in Saturday night by wildfires burning both in the region and around B.C.
Fine particulate matter, also known as PM2.5, refers to airborne solid or liquid droplets with a diameter of 2.5 micrometres or less. PM2.5 can easily penetrate indoors because of its small size.

People with chronic health conditions were asked not to engage in strenuous exercise until the advisory is lifted.
Infants, the elderly and those who have diabetes, lung or hearth diseases are particularly at risk.
Anyone experiencing symptoms including chest discomfort, shortness of breath, coughing or wheezing should speak to a healthcare provider.
Although it is colder outside this week, it’s still important to stay cool and hydrated and seek out indoor spaces with air conditioning.
