Sure.
On the first question, I would return to the notion that openness should be the rule, not the exception. If a meeting quickly goes in camera for legitimate reasons, then a meeting goes in camera for legitimate reasons. If it doesn't come out of the in camera session until the committee decides to adjourn the meeting, then so be it. But I think it should be coming at it from the standard that everyone is allowed in until there's a legitimate reason to remove people who shouldn't be in the room.
On the second question, I'm not sure I have an answer that would give much respect to the question. Off the top of my head I'd be guessing, so I don't know if I can address the crown corporation question.
