The first professional hockey rivalry between the two cities dates to the founding of the Western Canada Hockey League in 1921. Both cities received teams, Calgary the Tigers, and Edmonton the Eskimos. The Eskimos won the WCHL title in 1923, but lost the Stanley Cup to the rival National Hockey League's Ottawa Senators. Calgary also appeared in a Stanley Cup championship series in 1924, but lost to the Montreal Canadiens of the NHL. After the demise of the WCHL in 1927, Alberta hockey fans turned to junior hockey. Both cities had teams in the Western Hockey League and Alberta Junior Hockey League.
