Summary:

• Ground-level ozone is one of the damaging components of smog. 
• Smog levels have risen in most of North America east of the Mississippi and south of the boreal forest to levels previously associated with smog basins such as Los Angeles.
• Ground-level ozone measurements are now available on the Web for both Ontario and the United States.
• This paper takes Ontario ozone measurements and displays them in colored maps to show which areas have highest exposures
• Rural Southwestern Ontario has frequent high ozone readings well into the level at which human health effects are seen
• Even Haliburton-Muskoka regions have several episodes per year of poor air quality
