The Ottawa Nationals were a professional men's ice hockey team based out of Ottawa, Ontario, Canada that played in the World Hockey Association (WHA) during the 1972 73 WHA season. The WHA had originally announced a franchise to Doug Michel for "Ontario." Original plans called for the team to play at Maple Leaf Gardens in Toronto. However, Michel couldn't get a suitable lease for the Gardens. Afterward, there was some expectation that Hamilton would be the team's home, but the franchise was eventually placed in Ottawa. Nick Trbovich became majority owner before the season began, with Michel running hockey operations. The Nationals were coached by Billy Harris and led on the ice by Wayne Carleton, who scored 42 goals and 92 points during the season.
