I'll say a couple of things, and I think this is one Michel Leduc may want to add a little bit on.
On demographics, yes, Canada has an aging population, somewhat offset by net immigration, but it is a challenge for the country and for the fund. The chief actuary models that in and models in expectations for demographics and the aging of the population—birth rates, death rates, longevity rates, etc.—and the fund is sustainable under the chief actuary's assumptions. That is all factored into the sustainability of the fund in the latest report.
If you, as the federal and provincial stewards of the fund, decide that you want to adjust benefits, it certainly is within your purview to do that. Our job is to invest the money we get and to make sure, ideally, that we give you that flexibility over time by making sure that the returns exceed the expectations set by the chief actuary. We work extremely hard every day to try to give you that flexibility over time.
