I don't think you can look at any single economic indicator and say that it is the panacea that describes absolutely everything. As I described in my opening remarks, the consumer price index aims to measure how much it costs consumers to own a home. For sure, you'd include mortgage interest costs. For sure, some aspects of the price of the house are going to figure into it. There are other price indices, such as our residential property price index, which measures the purchase price of the house. That would be the proper index to use if you were taking a look at the prices that consumers are facing when they are purchasing a single home.
Similarly, I would take a look at the national balance sheet accounts to see overall household indebtedness and the mortgage debt that's being taken on by homeowners. I would also take a look at changes in household wealth over time in the national balance sheet accounts.
To develop a comprehensive picture, the CPI is developed, really, for two things. One is to be a means to escalate things like cost-of-living increases in contracts and stuff like that. The second is to be a tool to help inform monetary policy.
If you want that broader narrative on the issues facing Canadians, I don't think we can narrow it down to a single indicator.
