Competition for National Championship in the Junior "B" classification was initiated by the Canadian Lacrosse Association in September, 1964. A silver cup donated by Castrol Oils limited served as the winner's trophy (1964 - 1971) but was retired to the Canadian Lacrosse Hall of Fame, New Westminster, B.C. in 1972.
In 1972, the C.L.A. inaugurated the Founder's Trophy (1972 - Present) as emblematic of the Junior "B" Championship of Canada. this beautiful handcrafted unique trophy commemorates the founders of organized Lacrosse, particularly the contributions of "The Father of Organized Lacrosse", Dr. George W. Beers of Montreal, Quebec who wrote the first rulebook and in 1867 was instrumental in organizing the National Lacrosse Association, predecessor to the Canadian Lacrosse Association
