There are a number of differences. One is on a variety of affordability measures. In fact, the IMF's affordability measure showed that Canadian housing is the cheapest, along with Austria, in a 20-odd country comparator of all the major economies. That's one example.
Secondly, the debt service ratio of Canadians is still very achievable, or very modest, at around 7.5% to 8% relative to historic averages.
Another difference is that the level of unoccupied housing is still low, with the odd market exception, but it is still low and below historic averages, and certainly below any other period when we've seen things come off.
The fourth thing that is different, because the original question mentioned the subprime situation in the United States, is that the structure of our housing finance is entirely different from the structure in the United States. The implications of any adjustment in house pricing, up or down, for our financial institutions, our financial system, and then reverberating more broadly back in the economy, is not possible in our system of the U.S. magnitude.
