Thanks Andrew, I just looked and you are right.
Section 3 of the federal act listing prohibited weapons does not say anything about blade length, though it does specify some styles of knives.

I might have made a mistake, or it might be Provincial or municipal.
Either way I stand corrected and thanks for pointing it out.

However, Dean, people have been charged with prohibited weapons just for carrying a buck knife.
There is also a charge of "Possession of weapon for a purpose dangerous to public peace" which lets them charge you with anything as a weapon, even a folded newspaper, based on intent.

So think about what Andrew said at the end about how you carry, why you carry and where you carry that toad sticker.

Edit;
Maybe the best way to answer is say, "Ask yourself if you would stop you and question you if you were a cop."
