The Governor General's Trophy is an Interprovincial double rink men's competition, played since 1874. Originally the final was played in the one-sheet rink at Rideau Hall, one game in the morning and one in the afternoon, using a cumulative points system to determine the winner.
Today, playdowns in the OVCA and Curling Quebec produce the two finalists. The final is traditionally played in Ottawa in conjunction with the Ladies Curling Association Lady Tweedsmuir double rink competition. A representative from the office of the Governor General of Canada attends the banquet and presents the trophies and pins to the participating teams.
