The 1966–67 CMJHL season was the inaugural season of the Canadian Major Junior Hockey League. The fledgling league was formed by five members of the former Saskatchewan Junior Hockey League, along with the Edmonton Oil Kings and the Calgary Buffaloes. However, the league did not receive the sanction of the Canadian Amateur Hockey Association, and was considered an "outlaw league" whose members were ineligible to compete for the Memorial Cup. The CMJHL's inaugural season featured seven teams based in Alberta and Saskatchewan and a 56-game schedule. The Oil Kings topped the regular season standings with 34 wins; however, the Oil Kings were upset in the playoffs by the Moose Jaw Canucks, who went on to win the President's Cup, defeating the Regina Pats in the league final.
