True, there are a few. But no way of doing it completely by the book.
There are essentially 5 ways of owning an MV in Canada:
1) Register it at a US address. (Maybe you work cross-border?)
2) Come to Canada as a visitor (on a work/study permit) and bring it with you. You are not allowed to sell it and it has to leave when you do.
3) Hope the person at the DMV is clueless, or is a friend and knows how to circumvent the system.
4) Work for the government department that is allowed to import vehicles for testing purposes. (My old friend's neigbour did that and used to come home in stuff no-one else had ever seen.)
5) Conceal the bike's identity by transfering the frame and engine numbers from something else, and hope you don't get caught.
If anyone that actually owns one in Canada wants to add their method to the list, feel free.
Note that it's even impossible to import one for use on the track if it's a model that was originally sold for the road, even if it is not in road trim. So you can import a Veltro, but not a road MV.
