When ministry staff observe or forecast air quality to reach the poor AQI category, the ministry will issue a Smog Advisory.
High pollutant levels can have serious impacts on human health. The ministry issues Smog Advisories to help the public minimize the risk of health impacts and to ask the public to cut back on activities that contribute to poor air quality.
The Smog Alert Network is a notification service that provides advanced warning when poor air quality may be on its way. Visit the Smog Alert Network information page to learn more or join the network.
