Right, but this is Canada. Though, from what Blu says, it doesn't look to be a problem.

And now, since I'm going to be a law student in three years, I present the statutes:

89.
(1) Every person commits an offence who, without lawful excuse, carries a weapon, a prohibited device or any ammunition or prohibited ammunition while the person is attending or is on the way to attend a public meeting.
Seems to me that carrying a sgian dubh qualifies as a legal excuse, especially with the precedent set recently regarding the carrying of kirpans. Legal on the grounds that it's a religious thing. Sgian dubhs are a cultural thing.

90. (1) Every person commits an offence who carries a weapon, a prohibited device or any prohibited ammunition concealed, unless the person is authorized under the Firearms Act to carry it concealed.
Now, I doubt that a sgian dubh would be considered concealed, since you can see part of the handle at all times. Probably not a problem here.

So, the federal government doesn't seem to prohibit it, but I'm not sure about the province. So I think I'll still ask.
