Not to nitpick, but that is a crime just about anywhere. Under the Criminal Code of Canada, it is illegal to "produce a false alarm of fire", and that applies not just to pulling an alarm but also to shouting "fire". It involves serious jail time.
Canada is moving toward more gun rights, but they have a bad habit on 1st amendment rights.
My point is that if someone shouts fire in a theater it is ridiculous to pass laws on theaters or speech that are draconian.
