The Heritage Classic was an outdoor ice hockey game played on November 22, 2003, in Edmonton, Alberta, Canada, between the Edmonton Oilers and the Montreal Canadiens. It was the first National Hockey League game to be played outdoors as a part of regular season play. The Heritage Classic concept was modeled after the success of the "Cold War" game between the University of Michigan and Michigan State University in 2001. The game was given the tagline "A November to Remember".
