Just to illustrate the Canadian law regarding weapons of the non-prohibited sort, I noticed this article on the CBC today. The man was originally charged with assault with a weapon for hitting a fleeing robber with the blunt side of a hatchet.

I'm guessing anything could be considered a weapon if the Crown decides the individual was intending to use it as such at the time.
