The Toronto Rock, which operate in the National Lacrosse League, were founded in 1998 as the Ontario Raiders in Hamilton. The following year, the team moved to Toronto proceeded to finish first every year from 1999 to 2005 and won the league championship in five of those seven seasons. The city previously had several professional box lacrosse teams. A team named the Toronto Maple Leafs competed in the first season of the professional International Lacrosse League in 1931 at the Arena Gardens. Following the season, a new franchise was awarded to Conn Smythe on behalf of Maple Leaf Gardens Ltd. (MLGL), which was also named the Toronto Maple Leafs, with the previous season's Maple Leafs being renamed the Tecumsehs. Both teams played at the newly opened Maple Leaf Gardens. Smythe pulled out following the season due to financial losses, and the league didn't play the following year. Toronto also had a team in the American Box Lacrosse League in 1932.
