When the exchange favoured bringing cars into the Canada from the US, as long as the all the safety features satisfied the gov't, you could just drive it across and pay sales tax when you registered it. It's a NAFTA rule. If the car is not built in North America then there was an additional excise tax of about 6% IIRC. It would work the same both ways I'm sure but you should be able to research and decide if it's worth it. Some manufacturers honored warranty and some did not, so check that too.
