I've only looked at the U.S., but I've certainly looked a lot at the U.S. I'm talking grocery retailing. It's a very popular industry to study in strategy classes with students—that and airlines.
In terms of profit margins, I'm talking percentages. We're not talking dollars, because of course the U.S. is 10 times bigger. When you look at the margin, the ratios and the percentages, they're astonishingly similar at the grocery retailing level in the States versus Canada. It's a remarkable similarity.
