I would suggest going to carburner.com
It details all the ins-and-outs of importing a vehicle including costs. It's a crude site and is completely a one-sided argument for importing, but you get get all the details you need.
Basics are:
You will pay GST on your vehicle at the border plus a ~$200 RIV fee.
You will need to have the vehicle inspected by Canadian Tire to be certain it meets Canadian requirements.
You will pay PST (if applicable) when you register your car.
If your vehicle was not built in North America you will pay a 6.1% import duty. Nothing if it was built in NA.
Your time. Your travel costs.
Sites you need: riv.ca (tells you what vehicles you can import)
apa.ca (tells you who honours warranties in Canada
canadiandriver.com/forum (to tell us how everything goes

)
OR...
You can find a broker who charges ~$500 to ~$1000 to import a vehicle for you.
If you have the cash and are willing to spend even a marginal amount of time looking into this, it can be quite a worthy pursuit.
