From what I understand, for Canada, it will only work if you are a US subscriber with US equipment and you travel to Canada.

NavTraffic is NOT available to Canada Market yet

Also, seems that for TO and Mtl, you would only get accidents and not full traffic

Wow that is kind of amazing that Albuquerque and other parts of NM are on this so soon. Usually NM gets everything cool last, unless it is a bomb.

XM says they expect XM NavTraffic to be available in 200,000 vehicles by the end of 2008.

Great now everyone will have this and when there is a wreck the side streets will be flooded with cars and more wrecks.
