sent this out in a PM many times I suppose I might as well post it here.
Quick Run-down about buying bikes:
1) Well first thing you gotta do is ask the seller to give you a copy of the ownership. You then fax that over to the US customs office at the port you want to bring the bike out of. You then have to wait 72 hours(3 days).
2) You go down and look at the bike. If you like it you buy it. You take your title and make sure the seller writes you up a bill of sale. You go to the Us customs office on your way back and they stamp american title.
3) You head back to Canada. At canadian customs they look at the bike, make sure it has the certificate of compliance label on the frame etc. You pay GST and get some forms from the Canadian customs after you pay your GST.
4) Take your bike home to Canada... The hard part is done. You go online and pay your RIV fee. A day or so later they e-mail you your Inspection form. You can check your case status online and make sure you follow up with them because in my case the idiot at the border wrote messy and they couldn't read the form which held up my stuff for a day for no reason.
5) Once you get the RIV inspection form you take your bike to Canadian Tire and have it inspected. At this point it's supposed to have stock reflectors etc and KM/H speedo. Once Canadian Tire gives you the OK you are good to go
6) You take your CT paperwork and the US title and the Customs forms etc etc and you go to the ministry and they make you a Canadian title. At this point I recommend you get a temporory plate sticker so you can ride the bike to the mechanic instead of having to trailer it. You go get your safety done (make sure it's insured so you can ride it first) and then go get your real plates.
7) You now have a Canadian title bike, street legal and ready to enjoy all over the Canadian roads
