Canadian law prohibits any knife that is deployed by a mechanical button or by centrifical force. So basically, no autos or balisongs.
However, the actual letter of the law may be interpreted differently depending on the person enforcing it. For example, AO knives are sometimes mistaken for switchblades, and there is a chance that a police officer might want to confiscate it from the owner. But as long as you're not doing anything stupid with your knife, or getting arrested for some other reason, I think you'd be alright.
