This will work in canada. You see them all the time at future shop. XM or Sirius. My dad is a die hard Satellite Radio subsriber in good old Newfie land (XM i think). So if it works there it'll work anywhere.
As to if you can get it factory from the Jeep/Chrysler dealers in Canada I do not know. I haven't seen it as an option so aftermarket may be the only way to get it.
