A shortage of players following World War II forced the Terriers to cease operations in 1947. The Portage Terriers would be reborn twenty years later as members of the new Central Manitoba Junior Hockey League. The CMJHL lasted only one season before it merged with the MJHL. The Terriers became a Junior 'A' club following the reorganization of Canadian junior hockey in 1970. In 1972-73, the Terriers won the ANAVET Cup as Manitoba-Saskatchewan champions and Abbott Cup as Western Canadian champions, and then defeated the Pembroke Lumber Kings to win the 1973 Centennial Cup.
