On November 6, 1915, a game won by the Toronto Argonauts 19–15 over the Ottawa Rough Riders was called because of darkness and protested by Ottawa. An IRFU executive upheld the protest and declared the result as no-game.
In the summer of 1915, the Winnipeg Rowing Club reformed as the Victoria Rugby Club (a.k.a. Winnipeg Victorias). On the eve of the 1915 MRFU season, the senior team of the Winnipeg Victorias pulled the plug on their season. The Victorias players continued to practice and on October 23, 1915, they played as members of the Winnipeg Canoe Club against the Winnipeg Tigers. The Tigers won the only game of the 1915 season by a score of 10–4.
