The Ontario Junior Lacrosse League® (The OJLL) is the premier junior men's box lacrosse league in Ontario. As the number one source for talent for the National Lacrosse League (NLL), it has been an essential stepping stone for aspiring lacrosse players. The OJLL is sanctioned by the Ontario Lacrosse Association (OLA) and Lacrosse Canada (LC), and it offers an exciting platform for young athletes to showcase their skills.

The league consists of eleven franchises across Ontario, including Brampton Excelsiors, Burlington Blaze, Kitchener-Waterloo LC, Mimico Mountaineers, Oakville Buzz, Orangeville Northmen, Peterborough Lakers, St. Catharines Athletics, Six Nations Arrows, Toronto Beaches, and Whitby Warriors. Since its official incorporation in 1933, the OJLL has fostered the growth and development of lacrosse communities throughout the region.

The Ontario Champion earns the prestigious Iroquois Trophy and advances to compete against top teams from Alberta and British Columbia for the coveted Minto Cup—the National Junior A Box Lacrosse Championship of Canada. Ontario has proudly claimed the Minto Cup fifty-seven times since 1937, showcasing the exceptional talent within the league. Join the OJLL and witness these future legends in action as they strive for greatness both on and off the lacrosse field
