The Air Quality Health Index is a public information tool that helps Canadians protect their health on a daily basis from the negative effects of air pollution.
In 2012 there has not been an average Air Quality Health Index reading of 7 or more for all of Toronto (there are four monitoring stations in Toronto). But, the AQHI measured at an individual station has reached 7 or more this year. Below is a list of the dates that an individual station has measured a reading of 7 or more.
Air Quality Health Index Readings are provided on an hourly basis and a forecast is also provided for the next day.
