Doesn't the KEG buy Canadian processed beef? If I recall correctly they do. They don't advertise CAB, they advertise 28 day aged AAA (choice) beef. Unless they have changed in the recent past.

Earls switched from CAB when it wasn't licenced in Canada to Canadian Certified Angus Beef until it was no more, the association was sued for using a trademark illegally. They had been asked a few years before if they wanted to sign on for free but in the wisdom of the board they said no. CAB is now licenced in Canada and is Canadian beef processed in Canada to the same standards the US association approved.
