Very cool! Albeit in flash and some ui issues when trying to see the map, the legend and there is no way to link to the docs or access explanations associated with the timeline at the bottom but very interesting to see an attempt at making this kind of toxic data accessible!

Superfund365, A Site-A-Day, is an online data visualization application with an accompanying RSS-feed and email alert system. Each day for a year, starting on September 1, 2007, Superfund365 will visit one toxic site currently active in the Superfund program run by the U.S. Environmental Protection Agency (EPA). We begin the journey in the New York City area and work our way across the country, ending the year in Hawaii. (We will need a beach vacation by then!) In the end, the archive will consist of 365 visualizations of some of the worst toxic sites in the U.S., roughly a quarter of the total number on the Superfund’s National Priorities List (NPL). Along the way, we will conduct video interviews with people involved with or impacted by Superfund.

I wish I could find more Canadian examples!
