Hockey Canada, which merged with the Canadian Amateur Hockey Association in 1994, is the national governing body of ice hockey and ice sledge hockey in Canada. It is a member of the International Ice Hockey Federation and controls the majority of organized ice hockey in Canada. There are some notable exceptions, such as the Canadian Hockey League, U Sports (formerly known as Canadian Interuniversity Sport), and Canada's professional hockey clubs; the former two are partnered with Hockey Canada but are not member organizations. Hockey Canada is based in Calgary, with a secondary office in Ottawa and regional centres in Toronto, Winnipeg and Montreal.
