1917 NHA Season

League Note
After the 228th Battalion and Toronto dropped out of the league, the schedule was revised so that the remaining teams would play a 20 game schedule of two halves containing 10 games each. Some of the games to that point were moved into the second half. The 'second half' standings therefore include some games that the 228th and Toronto played. The owner of the Blueshirts would file several lawsuits over the league's actions, sparking the events that led to the founding of the National Hockey League (NHL)
