Okay, Anna, maybe the other pronunciation is not of itself deplorable. What I find deplorable is that a) CBC, once, when dinosaurs roamed the earth, the bastion of good Canadian English, has adopted this American pronunciation and b) the confusion. If I say "It was a complete rowt", how can you tell if I am referring to my new mail delivery job or the ousting of, say, hunters from my (posted) property by me with my little old frying pan?
Mostly b, I guess, although there is also a certain amount of protectiveness for my national liguistic identity.
