I highly recommend the VW tdi (turbo diesel). They're easy to find at most VW dealers. It's in jetta wagons, golfs, and beetles. They are sold all over Canada and have only minor issues with cold weather. Mike is a little misinformed. If you want one used, look at www.tdiclub.com and go to forums/cars for sale. You can also read all about the cold weather issues there.

It pulls my P19 with no problem. It also gets almost 50 mpg without the boat and will cover 700 miles on a tank of fuel.
