The Monarchs repeated as Manitoba provincial champions in 1914–15 as Maxwell again scored three goals and two assists during regular league play. The team reached the 1915 Allan Cup finals, where they challenged the Saskatchewan champion Melville Millionaires who held the Cup. Unlike the previous year's single-game contests, the 1915 final was played as a two-game, total-goals series. Melville defeated Winnipeg by a 4–3 score in the first game, but the Monarchs overcame a two-goal deficit in the second match to win 4–2 and win the series on an aggregate total of seven to six. There were no further challenges, and Maxwell and the Monarchs ended the season as Allan Cup champions.
