Mr. Speaker, we would turn to the general criminal law and for various defences that would be available, including the defence of duress. That would enable people to say that they had no choice but to do what they did in harbouring. However, it is a pretty onerous standard and so it is not easily available if someone feels constrained versus actually threatened. If they are threatened, then they would have a defence.
