The Toronto Shooting Stars joined the professional National Lacrosse League (unrelated to the modern NLL) for its inaugural season in 1972. When a new professional league launched as the National Lacrosse League (again unrelated to today's NLL) in 1974, the Toronto Tomahawks were included as a charter franchise. The Shooting Stars continued as an amateur team in the Ontario Lacrosse Association, but folded following the 1974 season. The Tomahawks were sold following the 1974 season, and received league approval to move the team to Nassau Veterans Memorial Coliseum in Long Island, New York. However, ultimately it was decided to relocate the team to Boston to become the Boston Bolts for the start of the 1975 NLL season, with the Rochester Griffins becoming the Long Island Tomahawks.
