Generally people in Edmonton, Alberta call Calgary cow town.
Probably because Calgary seems to be more cowboy oriented and they make a huge deal out of their Rodeo!
Edmonton gal: "Ha! Cow Town!... ok lets go"
Torontonian 2: "Ugh. You want to go to Cowtown?"
Torontonian 1: "Ya man, I want to wrangle me a Cowboy"
cowtown's commonly advertise for new blood with a low population count under their town signage.
