Notes on FinalEdit
1. The May 5th game was stopped at midnight at a tie because of the Ontario law banning games on Sundays.
2. It was decided that the May 10th game would be worth 4 points in order to speed up the series. It was very late in the season and the attendance was very poor (4-5000 per game).
Notes on PlayoffsEdit
1. The Valleyfield Braves had to play their home games at Montreal because their hometown arena was not big enough to satisfy the Canadian Amateur Hockey Association.
2. The Toronto-Saskatoon semi-final series was only the second playoff ever to be played in both Eastern and Western Canada. The first was in the 1947-48 Western Canada Memorial Cup Playoffs. The only other amateur series that dd so was the 1968-69 Memorial Cup Final.
