Before the 1915–16 season, Frank Robinson sold the Toronto Blueshirts — the NHA's other Toronto franchise — to Livingstone. The NHA did not want one owner to have two clubs in the league, and Livingstone said that he would sell the Shamrocks. But Frank Patrick and Lester Patrick of the Pacific Coast Hockey Association, who had accused the NHA of reneging on an agreement with their league, raided the Blueshirts and signed away most of the team's players. To fill the holes in his lineup, Livingstone transferred Shamrocks players to the Blueshirts, but that left him with little to sell in the Shamrocks. When he had not sold the team by the November 20, 1915, deadline set by the league, the NHA seized the franchise and kept it dormant for the season. Before the season began, Livingstone argued with the owners of Arena Gardens over the terms for the use of their facility and threatened to move his team to Boston. The NHA said that it would not allow the move.
