I would also add that the Australian intelligence agency has powers to question people under warrant, but those are highly circumscribed.
One of our concerns with the preventive arrest provision, which I recognize is about the police, is that there is nothing in Bill C-51 that regulates what happens to the person when they are detained on reasonable suspicion, potentially for as long as seven days. I think we could actually learn something from our Australian colleagues with respect to regulating detention.
