The Southern Ontario Secondary Schools Association (SOSSA) is a non-profit organization fueled by passionate volunteers who support secondary school athletics from Hamilton-Wentworth to the Niagara Peninsula. Our mission is to ensure interscholastic sport is delivered with fairness, accessibility, and educational purpose at its core.

As proud members of the Ontario Federation of School Athletic Associations (OFSAA), we work to provide student-athletes with opportunities that inspire growth, sportsmanship, and success beyond the playing field.
