I shipped all of mine with my household goods, inventoried, inside my gun safe. Didn't need FFL paperwork for that.
There are ways through Canada for long guns, but forget it if you have any kind of record. It really isn't worth the hassle that the Canooks put on it. Handguns aren't allowed into Canada for any reason and if you ask, you will be treated like a common criminal.
I would suggest that he talk to a local, reputable FFL holder, hell talk to a couple of them, and get their take on it.
IMO it ain't worth the hassle dealing with the socialist pigs in Canada. (I'm spouting about the government, not anyone in particular)
