Ligue de hockey senior du Québec
In the late 1940s, Lockhart made an interlocking schedule between the EAHL and the Quebec Senior Hockey League, which allowed New York fans to see the all-black line of Herb Carnegie and his brothers play with the Sherbrooke team. As the league president, Lockhart suspended a player for life in 1952, after Joe Desson assaulted referee Mickey Slowik on the ice.
