I shop at Farm Boy, and Farm Boy is a very successful local chain out of Cornwall that has about 10 stores and is growing by leaps and bounds in Ottawa. I don't know what beef it is, but they have Canadian beef. If they're having trouble getting beef, or chicken, or a major product that such a grocery store would sell, then obviously it's a problem. I'm not aware that they're having trouble. They may not be able to get every brand, but they are certainly able to have a full store.
I'd just ask you to look at Farm Boy. It's an independent grocery store run by a family in Cornwall; it's extremely successful. It's on its tenth store now. It seems to have all these products, so it has overcome these restrictions.
