The 1916–17 campaign was a stormy one for the NHA. Canada intensified its contribution to World War I, and a number of pro and amateur hockey players volunteered for military service. The 228th (Northern Fusiliers) Battalion, CEF of the Canadian infantry formed a team in the NHA, taking the place of the suspended Toronto Shamrocks franchise and sharing Arena Gardens with the Blueshirts. Meanwhile, Livingstone lost several of his Blueshirts to the war effort: Harry Cameron, George McNamara, Howard McNamara, and Percy LeSueur. Keats had also joined the 228th, and Livingstone protested to the league about the loss of his star player. The two clubs eventually reached an agreement where Keats was returned to the Blueshirts in exchange for the right to use LeSueur. Another of Livingstone's stars, Cy Denneny, had found full-time employment with the government in Ottawa and told the team that they could either trade him to Ottawa or he would sit out the season. Livingstone said that he would not accept anyone but Frank Nighbor in a trade, or Ottawa could buy Denneny for $1,800—more than double the NHA record for a player sale. He then suspended Denneny in November for refusing to report. Livingstone also offered to take goaltender Clint Benedict for Denneny, but that offer was also rejected by Ottawa. Late in January 1917, it seemed that Livingstone had traded Denneny to the Montreal Wanderers for goaltender Billy Hague—Denneny even signed an agreement with Montreal—but Livingstone backed out of the deal with his nemesis Sammy Lichtenhein. Livingstone ultimately capitulated and sold Denneny to Ottawa, but not before raising the ire of Tommy Gorman in Ottawa and Lichtenhein in Montreal.
