Our methodology's been around for a few decades now. We take a set of types of dwellings—single, multi, etc.—in the various geographies in the country, and then we measure that over time. That's how we get at the new house pricing index.
Again, as I mentioned, in the CPI, we consider home ownership an asset that, if you like, you gain over time. You do factor in interest rate costs, utility costs, and maintenance and insurance costs. That's how we measure, in the CPI, a good that represents the overall shelter cost, of which homeowners' replacement is a subset that is weighted to what Canadians spend overall in a given basket.
