His younger brothers Billy, Bob and Frank would also become professional ice hockey players.

In October 1916 Boucher enlisted with the Canadian military, joining the 207th (Ottawa-Carleton) Battalion, though he was discharged in December that year for unclear reasons.

However he was again discharged, this time on account of a medical exam finding him to have a mitral regurgitation, or leaky heart, which made Boucher unfit to be a soldier.

[2] Buck's son, Frank Boucher, was the head coach of Canada's 1948 Olympic gold medal-winning ice hockey team – the Ottawa RCAF Flyers.

He would play with stars such as Eddie Gerard, Horrace Merrill, Sprague Cleghorn, Lionel Hitchman and King Clancy.

[5] He suffered from throat cancer for six years and was inducted into the Hockey Hall of Fame in 1960, three weeks before he died.
