UPDATE: Metro Vancouver has ended the Air Quality Advisory that was in effect for Metro Vancouver and the Fraser Valley Regional District since Tuesday, July 18, 2017. The advisory was due to elevated concentrations of fine particulate matter from wildfires in the Interior of B.C. Air quality throughout the region has now improved as a result of stronger winds in advance of an incoming low pressure system. Please visit www.metrovancouver.org for more information.
Metro Vancouver is now issuing an Air Quality Advisory for Metro Vancouver and the Fraser Valley Regional District because of high concentrations of fine particulate matter due to wildfires outside of the region. These conditions are expected to persist for at least 24 hours.
Fine particulate matter, also known as PM2.5, refers to airborne solid or liquid droplets with a diameter of 2.5 micrometres (μm) or less. PM2.5 can easily penetrate indoors because of their small size. The PM2.5 currently impacting our air shed is primarily smoke that has been transported into our region from wildfires burning in the interior of BC.
This advisory is expected to continue until there is a change in either the fire activity in the BC Interior, or the weather patterns that are currently transporting the smoke into the region.
Persons with chronic underlying medical conditions should postpone strenuous exercise until the advisory is lifted. Exposure is particularly a concern for infants, the elderly and those who have diabetes, and lung or heart disease. If you are experiencing symptoms such as chest discomfort, shortness of breath, coughing or wheezing, follow the advice of your healthcare provider. As we are in the summer season with warm temperatures, it is also important to stay cool and hydrated. Indoor spaces with air conditioning may offer relief from both heat and air pollution.
Metro Vancouver works in cooperation with Environment and Climate Change Canada, the Fraser Valley Regional District and B.C. Ministry of Environment to look after air quality.

What is fine particulate matter?Fine particulate matter, also known as PM2.5, refers to airborne solid or liquid droplets with a diameter of 2.5 micrometres (μm)or less. PM2.5 concentrations tend to be highest around busy roads, industrial operations, major ports as well as areas withresidential wood burning. PM2.5 can easily penetrate indoors because of their small size.
Tips to reduce your personal health risk:
And especially for persons with chronic underlying medical conditions:
Voluntary emission reduction actionsReducing sources of fine particulates throughout Metro Vancouver and the Fraser Valley will be beneficial to air quality. Actionspeople can take:
Under provincial legislation, Metro Vancouver is responsible for monitoring air quality, controlling industrial, commercial andsome residential emissions, creating long-term plans, and conducting emission inventories for the Metro Vancouver region.
To help reduce air emissions throughout the Lower Mainland, Metro Vancouver works cooperatively with the Fraser Valley Regional District, the B.C. Ministry of Environment, Environment and Climate Change Canada and other agencies to develop and implement emission reduction programs for businesses and local residents. Further information about air quality programs in the region can be found on Metro Vancouver’s website at www.metrovancouver.org.
