Boon was uncle to Lucille Wheeler-Vaughan, Canadian and world ski champion.

Considered to be 'fast and wiry', Boon is credited with being the first player to use the poke check, which he used to great success in stopping opposing forwards.

[3] Boon was the captain of the two-time Stanley Cup-winning Montreal HC teams of 1902 and 1903 which had several other future Hall of Famers including Jimmy Gardner, Tommy Phillips and Jack Marshall.

Although Boon was a multiple winner of the Stanley Cup, he was not happy with it interfering in the season of play.

The negotiations were unsuccessful and the team was instead nameless, until the nickname "Maroons" came into use, after the colour of their sweaters.

[6] After retiring from playing hockey, Boon became a co-founder of the Boon-Strachan Coal business, and he took up curling and golf.

He had continued to curl until 1959, when he was injured in a golf cart accident that fractured his pelvis.
