The Whitby Minor Lacrosse Association is the largest in the Toronto area. The league has built itself from a small association of less than 100 players in the mid-1980s to over 800 players spread out among 60 house league and rep teams.
Most divisions have three rep teams each.
Whitby encourages players to join at the paperweight age as it provides a solid foundation for future years. All rep coaches are certified and the association encourages house league coaches to do so as well. The 1997 season featured Whitby hosting the annual celebrity lacrosse tournament.
