The 1925 Allan Cup was the senior ice hockey championship for the Canadian Amateur Hockey Association (CAHA) during the 1924–25 season.
In February 1925, CAHA vice-president Frank Sandercock submitted a proposal to change the Allan Cup finals to a best-of-three games format instead of a two-game series decided on total goals scored.[1] [2] Public sentiment at the time was that in a two-game series, a lucky break was enough to decide the series, whereas a best-of-three format was less likely for that to happen.[3] CAHA president Silver Quilty announced that the change was approved by a special vote and was put into effect for the 1925 competition.[4]
Port Arthur Bearcats beat University of Toronto 2-0 on series.
