Concealed carry in Canada?

I was told that you can get a permit to carry a consealed weapon in Canada. However I do not know if this has ever happened. I know certain police can carry off duty but a civilian? I'm sure it has only been issued to judges or witnesses in extream situations. I have had my life threatened by some pretty serious people while working as a correctional officer. Does anyone know if the government has actually issued these to anyone. I'm sure the new Carla Hamolka has one the way this government works.
