I'd make a couple of comments.
Canada is in a relatively unique position at the moment with this issue in that there are certainly individual items that have moved but food price inflation as a whole has been very muted in Canada. That's a product of a couple of things, we think. First, there's a surplus of meat in North America, so meat prices have gone down. Secondly, there has been some exchange rate pass-through from the past appreciation of the Canadian dollar affecting particularly meat prices, fish prices, fruit and vegetable prices in Canada. Thirdly, we have seen increased competitive pressure in the food retailing sector. Some of the big box retailers have moved in. Margins have gone down, and that process has gone through.
So in Canada to this point we have not seen those issues, but we certainly are attentive to what's going on globally, and attentive as well to the implications for inflation and expectations.
