Systemadude,
I'm from Northern Ontario, (Smooth Rock Falls) and have carried a knife since a kid. I'm now a Building Official, in the public eye, and carry a Laguiole 7.5" folding pocket knife in a belt sheath. No problem because it's a daily used tool, I've got a mini-mag and a cell phone on my belt too, all tools for the job.
This is from part three of FIREARMS AND OTHER WEAPONS, from their definitions (84.)
(a) a knife that has a blade that opens automatically by gravity or centrifu gal force or by hand pressure applied to a button, spring or other device in or attached to the handle of the knife, or
(b) any weapon, other than a firearm, that is prescribed to be a prohibited weapon;
so then we look at the definition of weapon:
weapon" means any thing used, designed to be used or intended for use
(a) in causing death or injury to any person, or
(b) for the purpose of threatening or intimidating any person.
So.. common sense applies.
Here have a nice little link to a search page for Canadian Law.
