Hi Avril:

The impression I get, from reading your post above, is that there is no doubt that you are a 'genuine' tourist, and you intend to use the motorcycle in Canada for pleasure tourism and no other purpose.

Assuming that you intend to export the motorcycle from Canada at the ultimate end of your journey, I can't see any reason why Canada Customs would object to you re-entering Canada from the USA. Clearly, you're not trying to pull any tricks like dodging across the border for half a day to have a coffee and 'reset the clock' or anything like that.

I cannot tell from looking at your blog exactly what you mean when you stated in your post immediately above "We shipped our bikes to Canada from the UK on a 12 month temporary import..." Normally Canada does not require any documentation or import permits when a vehicle is brought into the country for tourism. Perhaps you did something unique such as putting a licence plate from one of the Canadian provinces on it.

In any case, if you leave Canada within the time prescribed in your permit (and can document that you have done it), then there should be no difficulty at all re-entering at any time in the future, as long as the re-entry is for tourism purposes. But, next time you enter Canada with the bike, don't get any permits, please... just ride across the border like everyone else, show your passports, & don't hold up the line. That will save you encountering the same grief later on in your life.
