The first seller which became popular earlier during this year was a guy in Florida.
Note that on the above-linked page, they talk about using United Parcel Smashers (UPS) to ship to Canada.
If you choose that, expect a hefty brokerage fee added.
Last time that happened to me (several years ago), the fee was $35 on an item for which I had paid around $35.
The guy had promised to send it by P.O. but sent by UPS.
BTW, the item (a guitar part) was exactly as advertised, and in good condition.
