Metro Vancouver’s air quality warnings will now be issued as yellow (high health risk) and orange (very high health risk) to convey the level of risk to the public and the actions they should take to protect their health.
Metro Vancouver monitors air quality across the region to protect public health and the environment. Data collected from its network of air quality monitoring stations informs residents about current conditions, which can result in air quality warnings and public alerts during events like wildfire smoke.

The warnings explain the cause of the problem, where it is in effect, and what people can do to stay healthy.
