In 2009, the Toronto Nationals of Major League Lacrosse was established, with much of the roster of the Rochester Rattlers, which would be suspended, being transferred to the new Nationals' team. However, the name, colours, and history stayed behind in Rochester to potentially be used by a future MLL team. In their inaugural year in Toronto, the Nationals went on to win the Steinfeld Cup. In 2011 the team relocated to Hamilton, Ontario, and played their games at Ron Joyce Stadium. After the 2013 season the team announced they would not field a team the following season. The Premier Lacrosse League played a week of their inaugural 2019 season at Tim Hortons Field in Hamilton.
