I would reframe that slightly to say that we have taken steps to make the mortgage credit system a little bit safer, which in turn may cool the housing market, but our primary objective is credit quality.
What we have done is that we have put in place mortgage underwriting standards that we oblige all banks to follow, which causes them to make safer mortgages, which then sustains and makes their institutions more resilient.
The key thing that we do, and the most important thing we do, is that we set a common baseline. If all competitors in the system think they are all following OSFI's sound underwriting policies, then they themselves will follow sound underwriting policies. If we don't have those in place, they will think, “My competitor across the street is cheating so I'm going to cheat because I have to to compete,” so there is a game theoretic aspect to what we do. We put a baseline of sound underwriting standards in place to sustain the system through ups and downs.
