As I was mentioning earlier, there's a wide range of possible measures of inflation in Canada. On a longer-term basis, they all kind of settle in the same sort of area, but in the short term, they can be quite different.
In particular, the CPI can be heavily influenced by major movements in, let's say, gasoline prices, or food prices. Those are the classics. We used to just exclude food and energy; now we exclude the eight or nine most volatile components to give us a better guide as to whether the trend in inflation has changed, as opposed to volatile components of it, to give it more signal and less noise.
That just helps us appreciate whether the trend is still on track. It gives us a little more insight into whether we're being deluded by a major move in just one or two items. It's as simple as that.
But we do pay attention. Our target is about the whole thing.
