The Canada men's national ice hockey team is the ice hockey team representing Canada internationally. The team is overseen by Hockey Canada, a member of the International Ice Hockey Federation. From 1920 until 1963, Canada's international representation was by senior amateur club teams. Canada's national men's team was founded in 1963 by Father David Bauer as a part of the Canadian Amateur Hockey Association, playing out of the University of British Columbia. The nickname "Team Canada" was first used for the 1972 Summit Series and has been frequently used to refer to both the Canadian national men's and women's teams ever since.
