I havent experienced any difficulty in most airports / airlines with my weapons. Security will generally want to take a look, but so long as they are checked baggage, it shouldn't be an issue. The biggest problems I encountered was leaving Tokyo - my weapons bags were inspected a couple of times, but I have found "aikido" to be a magic word in asia & especially Japan - it will open doors like nothing else.

Depending on Canadian quarantine laws, you might have trouble importing wood products from overseas. I expected grief when I came into Australia, but they were pretty relaxed about it - I guess because bokken have obviously been processed / worked???
Cheers & good luck,
