The Thunder Bay Beavers were a Canadian Junior ice hockey club from Thunder Bay, Ontario. The Canadians were members of the Thunder Bay Junior A Hockey League and were 1972 National Centennial Cup quarter-finalists, losing to the eventual winner Guelph CMC's. History In 1971, American investors were brought into the Thunder Bay Junior A Hockey League. The result was an expanded league and changing the league's name to the Thunder Bay-Minnesota League. The new teams were the Minnesota Jr. Stars and the St. Paul, MN-sponsored Thunder Bay Vulcans. The name "Vulcans" came from an organization in the St. Paul area, but the team played in Ontario. In their first season, the Vulcans proved to be an instant powerhouse. With an undefeated 21-0-1 record in the TBMJHL regular season, the Vulcans also posted an overall record of 33-2-3 with combined regular season record and exhibition schedule versus the local NCAA loop (including the Lakehead Nor'Westers) and the semi-pro United States Hockey League. The Vulcans easily won the league title and moved on to the 1972 Centennial Cup National playdowns. In the first round they drew the Central Junior A Hockey League champion Smiths Falls Bears. The Vulcans masterfully defeated the Bears 4-games-to-1 and outscored them 36–19, including a 15-4 blowout win to clinch the series. In the National quarter-final, the Vulcans drew the Southern Ontario Junior A Hockey League's Guelph CMC's. Guelph edged out a pair of 5-4 victories to open the series. Game three was a 7–3 win for the Vulcans, and Game four was won 7–0. The CMC's rebounded in Game five with a 6–2 to take a 3–2 series lead. In Game six, the Vulcans defaulted the game only 1:42 into the first period. The coach of the Vulcans was unhappy about a series of calls the referee made and pulled the Vulcans off of the ice in front of 4,200 Guelph fans. The ref awarded the game to Guelph when it became clear that the Vulcans would not return. Guelph went on to easily win the Centennial Cup, leaving the boys on the Vulcans, who were far from down and out, wondering what could have been. In 1972, the TBJHL was renamed the Can-Am Junior Hockey League. Only the Vulcans, Jr. Stars and the Westfort Hurricanes went on with the league. The remaining teams dropped to Thunder Bay Jr. B. The Vulcans were sold by their St.
