I'll defer to my colleague, but in general I would say that probably on average it's about twice the rate throughout the north, and that is with the food mail program that already significantly reduces the cost from what it would otherwise be.
I would caveat that by saving that the prices throughout the north differ, depending often on the distance from southern centres, but for a variety of other reasons as well, so there's not an average kind of difference. Of course, the further north and the more isolated and remote the community, the more expensive it would be. The food mail program helps equalize those costs across the region.
What we can say with some assurance is that prices under food mail are much lower than they would otherwise be. The impact is the highest in the farthest and most remote and isolated communities. We could probably send you some examples as to what the situation is in various representative communities.
Fred, would you have other thoughts? Could you be more specific?
