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.
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.
In the National quarter-final, the Vulcans drew the Southern Ontario Junior A Hockey League's Guelph CMC's.
The Vulcans were sold by their St. Paul investors during the season and changed their names to the Thunder Bay Centennials.
The Centennials made it clear at the end of the season that they would not play another year in the increasingly American league.
