I'll try to answer it.
I have the study here, and we did read the study. The study doesn't really indicate why that has happened.
I guess you have to realize, if you're buying it from the same producer and it is a Canadian producer and they are shipping it down there, they have to add some costs for freight. So you can only assume either of two things: they're using a different price mechanism for producers or end users in the United States than they are in Canada or the retailers are charging more in Canada than they do in the U.S.
To be honest, we have the same problem. We're looking into this. It's quite hard to find prices, sometimes, from American retailers because of the fact that we are Canadians and they may be a little bit leery of giving this information out. Ag Canada seems to have more luck at getting information than we do, so maybe this is a step that Ag Canada could help us with.
