The office of the Environmental Commissioner of Ontario is studying local, street-level air quality and comparing it with ambient air quality reported through the Ministry of Environment's Air Quality Index (AQI). The AQI, although a report of air quality, does not look at the street-level scale. This summer, the program was expanded from street-level sampling of fine particulate matter in seven Ontario communities, to include ground-level ozone in nine Ontario communities. Conclusions and/or recommendations are expected in late 2008. The sampling locations for 2008 are: Kingston, London, Ottawa, Peterborough, Sault Ste. Marie, St. Catharines, Temagami, Kingston, Toronto, and Windsor.
