British vs. Canadian WEs

One of Dan's pet peeves if I recall correctly was people assuming the British WEs were identical to Canadian ones; I'd have to review the notes he wrote out for me in detail, but I seem to recall Bouchery had it wrong and that most references do - Terry Copp was another who simply parrotted British WE information instead of looking at Canadian WE info. Sorry to be vague; if Dan is around perhaps he can go into more detail as he is definitely the expert here.
