This smog advisory will remain in effect until further notice.

* 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.

Air Quality Index (AQI)

  • AQI is an indicator of air quality, based on air pollutants  that have adverse effects on human health and the environment.
    • Smog is harmful to the lungs and heart.
    • Even in healthy people, smog can reduce lung function.

  • 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, comprised of Ozone (O3) and/or Fine Particulate Matter (PM2.5), is primarily a summer phenomenon, occurring mostly in southern Ontario; however, PM2.5 can elevate smog levels during all months of the year.
      • For this reason, the ministry reports the AQI hourly, seven days a week; and continues to provide air quality forecasts daily.

The details of the smog forecast are as follows:

  • The smog advisory has been expanded, and now includes eastern, and parts of southern Ontario as a result of forest fire smoke being transported from northern Quebec.
  • A low pressure system, currently located southwest of the province, combined with a high pressure ridge over northwestern Ontario are forecasted to cause mainly cloudy skies and northeasterly winds across the province for today, July 2.
    • These conditions are expected to last into tomorrow morning, July 3, however as the systems move eastward, winds are forecasted to become southwesterly by tomorrow evening, clearing out the forest fire smoke.

  • On Thursday, July 4, a high pressure ridge is forecasted to lie southeast of the province, causing southwesterly winds and increasing temperatures across the province.
    • Partly sunny skies and a slight chance of showers are expected as a result of an upper-level disturbance.

    • Good to moderate air quality is expected across the province.

During the smog episode, individuals may experience the following symptoms:

  • eye irritation
  • heavy outdoor exercise may cause respiratory symptoms such as coughing or shortness of breath
  • people with heart or lung disease including asthma may experience a worsening of their condition
