Following up on Mr. Owen's point on the possibility of restricting circumstances, I'm not aware of any problem with this within the Canadian Parliament, but I have seen it with municipalities in some cases, such as school boards, library boards, and so on—the use of habitual in camera meetings as a way of essentially silencing dissent, making it impossible to discuss anything that was brought up in committee and then making sure that everything gets brought up there.
I don't want to impose an unreasonable burden on our researcher, but perhaps we could take a look at the potential for abuse of in camera by making too much in camera. That's really, I suspect, what Mr. Owen would like to guard against, and I would like to guard against it too.
