The way we have it set up is that the government implicitly is backing CMHC. They're backing the private insurers. In order to get that backing, they have to follow the rules that the Minister of Finance sets. Maybe we were looser on our lending criteria in 2007 than we are now, and they've tightened them up from the length of the amortization period to how much you can borrow, all those kinds of things.
The Minister of Finance can set those criteria, and because they don't get their backing if they don't meet those criteria, the insurers go along with it.
It's really quite a nicely designed system.
