To take your second question first, the link would be indirect. The link would be that with a collapse in the U.S. housing market, U.S. demand really slows down, our exports slow down, income growth in Canada slows down, and then that affects the housing market. I don't think there's a direct link at all.
Going to the first question, how concerned are we? We watch this pretty closely.
The third part of the question, which we didn't get to answer earlier on, is that in fact what we've seen is that household debt to income rises, but debt service costs to income actually have fallen fairly sharply. They've been flat over the last couple of years. They haven't been rising. That is quite a different story than is the case in the United States.
So from the household side, we don't see a particular problem. The question is, are there particular markets?
First of all, I think one has to note that up until 2003, Calgary and Edmonton had one of the lowest ratios of house prices to median incomes in the country. In fact, even though they recently had a very rapid increase, they only got back to where most of the rest of the country is because of their high incomes. Vancouver's lower mainland is probably the one market where the ratio of house prices to incomes clearly looks out of whack. But that would be the one.
