Well, we were talking about how the commissioner serves at the pleasure of the government, so he or she has the power to dismiss, I would think. However, that's something you disagree with, because you feel that compounds the problem in some way, so I'm not clear on what the answer is.
You say that a committee of Parliament should do the hiring of the commissioner for a fixed term, but as a practical matter, if you have a majority government, the government is going to be a majority on the committee. It's simply an extension, in many ways, of the will of the government, so it's not clear to me where the answer lies from your point of view.
