I don't think we can really add much more than we've already said. We're not the experts in housing. We don't do housing policy. Housing is an important part of the economy, but it's only part of the economy. We have to consider the whole economy.
I think what we can say with some confidence, based on what we've seen over the last decade, is that the fundamental issue is supply. What we've seen over the last decade is.... At first, we used a series of—I say “we”, but this is largely OSFI and, to some extent, the Department of Finance, the federal system—macroprudential measures to reinforce the stability of the system. Those mostly dented demand. When they were brought into place...for example, they lowered the maximum amortization and put in better stress tests. At OSFI, the senior deputy governor was directly involved in some of these in her previous role. Those measures dented demand, and they would bring the market into better balance temporarily, but because supply wasn't growing quickly enough, demand would eventually come back and we'd be in a similar situation.
You've seen us raise interest rates very forcefully. That's had a very direct effect on the housing market. It's very interest-sensitive. The market has cooled and housing prices have come down about 10%, but that's just affecting demand. It's not addressing the fundamental supply issues. The clear message from the experience of the last decade is that we're not going to solve this problem by addressing demand; we have to focus on supply.
