I don't know if this is the right place for this post, but I'll give it a try:
It's not to scare people, or to put Ontario in a bad daylight, but a report from 2008 showed that approx 9,500 people have prematurely died in the Province of Ontario due to Air Pollution / Smog.......and the number is growing!!!
Yes, that's bad!
Fortunately, you drive 1 hour up North, and you float in your canoe on a pristine lake breathing only fresh air!!!!
So I decided to add a few pages to my website in regards to Air Quality. See [Forecasts] on my website.
Toronto, a meltpot of 4 Million people sees especially in Spring/Summer a significant amount of 'Smog-Days', quite often caused by a 'free-gift' from our Southern Neighbours when S Winds carry the heavy industrial pollution from Michigan and Ohio towards Ontario.....
Have a look at the pages, and if you're interested, please drop a message on my (brand-new

[Site Contact] page since there are a number of scripts for each page, so I can ZIP them.
NOTE:
Some of the scripts run on Shockwave Flash (Graphs)
The scripts grab information from a specialized 'Ministry of Environment' website for Ontario (
http://www.airqualityontario.com/), however you can compare it with (similar) websites in your area (if available) and modify/tweak the scripts accordingly.
Cheers,
Arthur
