I think there may be issues relating to Bovine Spongiform Encephalopathy and shipping Alberta beef over to the US. You might want to ask the Alberta Beef Producers if any of their members ship. http://www.albertabeef.org
Food mail order is not a big thing in Canada. I've been looking for years & years of Canadian establishments that will sell premium(the absolute best) Canadian beef to consumers by mail-order. I don't know of any.
