Ive brought a few bikes/sleds back from the states before. It seems legit but as someone else says, have your bank- contact the lienholder and pay them directly. Then they can fax you a copy of the ownership. Im not exactly sure of any new rules but when I did it, you needed a "recall clearance letter" from the manufacturer(suzuki) saying that any and all recalls have been done and are up to date. I didnt get charged for it, but some guys have. You also need a bill of sale. Now listen closely---dont have him write you a bill for a much lower price. The border, our side, have been real *******s about this. My brother tried it with a $15000 truck, with a bill for 8grand, and they basically held him for 3 hrs threatened tp impound the truck, trailer , and new truck. Then they surfed the internet and actually found the guys old ad for the pickup advertising it at $15000 ! Needless to say, after $1000 bucks in fines and taxes, fees on the full 15000- it did not pay to try and save a couple bucks. Just a warning. Then theres also a $230 RIV fee which covers the cost of the paperwork and the provincial inspection. PM me for more info.
Its easy to do, you just gotta have all your stuff in order beforehand.
Good luck.
