During the smog episode, individuals may experience:

- smog is harmful to the lungs and heart
- even in healthy people, smog can reduce lung function
* A Smog Advisory means that there is a strong likelihood that there may be poor air quality within the next 24 hours due to ground-level ozone and/or particulate matter.
Hot, hazy and humid conditions combined with southwesterly winds blowing air pollution from the U.S. into Ontario will result in elevated smog levels across southwestern Ontario.
This advisory will remain in effect until further notice.

- A Smog Advisory is related to the Air Quality Index (AQI), which rates how clean the air is. The AQI scale ranges from 0 to 100+. Higher numbers mean higher health risks.
- A Smog Advisory is issued in your region when the AQI is expected to reach 50 in the next 24 hours. It can be lifted once the AQI is expected to reach or drops below 50.
- Smog is made up of a complex mixture of air pollutants that are sometimes visible, such as a brownish-yellow haze over cities; sometimes not. The two main ingredients of smog are ground-level ozone (O3) and fine particulate matter (PM2.5).
- Smog is harmful to the lungs and heart. Even in healthy people, smog can reduce lung function.

- Check out the Air Quality Index or AQI in your area.
