No I don't work for Canada Customs as they don't exist anymore however I am the Original poster of this sticky, which was written from FACTS and not my personal experience. While personal experiences may change, FACTS 9/10 do not.
To answer you next question. The guy here on vacation is allowed to bring his vehicle into Canada for personal use as a visitor under Customs Memorandom D2-1-1, tariff code 9803.(you can read it for yourself
http://www.cbsa-asfc.gc.ca/E/pub/cm/d2-1-1/README.html ) He does not have authorization to sell this vehicle in Canada. Therefore the bike is now subject to duty and taxes and seizure (officer's discretion of course).
Now zc911 think outside the box... if you were a Border Services Officer and someone told you the story you wrote above would you believe it? Keep in mind you hear dumb arse lame stories all day every day. Next question, would you go on vacation to the US with the sole intent of "going on vacation" take the time to pack, drive x amount of hours only to end up taking the bus home cuz some dude said he'd give you $3 grand for you ride?
