I wouldn't say we've done a cross-cutting study on every aspect of it. Certainly we've seen issues over the past few years with some of the railway performance, and there has been a lot of work done on that front. I can certainly share any of the work we've done on that front, if there's an interest.
I would say on the issue of food affordability that your question speaks very much to our perspective, in that Canada is one of the most affordable countries in the world in which to procure food. When we look at the stats, we find ourselves third in the world in cost per capita and the ratio of your disposable income that goes to food. Canada's producers are doing a lot of great work in terms of efficiently producing food on an affordable basis.
There are issues with transportation, particularly when you look at northern communities, and there's a lot of work to be done. I can't say we've done a comprehensive study of all the different aspects of trade and transportation barriers within Canada, but we certainly see it as a key element of a food policy, recognizing that primary producers in Canada and our food production value chain are doing a great job already of providing affordable food. Certainly transportation is an area in which more attention is needed, in some respects.
