First things first, go to
www.riv.ca, that site explains everythign about importing a vehicle into canada, as well as whether it can or can not be done. They have a list of all importable vehicles. Also you will be paying 6% (july 1) tax on the purchase price of the vehicle, as well as a duty fee if the vehicle was made outside of US/CAN/MEX. There is also a $150 excise tax if the vehicle has A/C. Then you have to get a national safety done on the vehicle at your nearest canadian tire.
If you have anymore questions regarding this just ask me, I just went through this a couple months ago.
