The 1917–18 Montreal Canadiens season was the team's ninth season and first as a member of the new National Hockey League (NHL). The Canadiens sided with other members of the National Hockey Association (NHA) and voted to suspend the NHA and start the NHL to expel the Toronto Blueshirts ownership. The Canadiens qualified for the playoffs by winning the first half of the season, but lost the playoff to the temporary Toronto franchise, made up of Blueshirts players. __TOC__
