COSSA is pleased to welcome student-athletes, coaches, parents and fans to another great year of high school athletics.  From the gymnasiums and fields to the ice rinks and pools, COSSA athletes and coaches will be competing for their schools in many different sports  over the year.

COSSA is also excited to celebrate the 75th anniversary of OFSAA!  We look forward to participating in the different initiatives and events that OFSAA is planning.

Best of luck to all athletes and coaches!
