You just gotta start calling marinas that sell Yamaha watercraft. That's how I found mine. Rusty Palmer's in Pennsylvania, they had one 08 on the lot back when I bought mine in 2008 (http://www.rustypalmer.net/). You don't need an American address or anything like that. Just be prepared to pay taxes when you come back across the border with it.
Where in Ontario are you?
Just find a dealer close to the border, drive down and pick it up.
Or you can get a freight forwarder close to the border and ship there...
Or, depending if the dealer wants to ship to canada just ship it directly to canada... you'll need to take care of some paperwork with customs.
I bought my used rn sj 2 years ago in FL.. found another used one in ontario last year and brought it to quebec.
