The OFSAA cross country championships are the Ontario high schoolcross country championships, held annually in varying locations around Ontario, usually on the first Saturday of November. Approximately 1600 runners compete in six races, making it the largest OFSAA meet of any sport.
Athletes may qualify to compete in the championships as a team or individually. Each of the nineteen Regional Associations under the OFSAA umbrella hosts its own qualifying event to select participants for the provincial championships. The top two teams and top three individuals (excluding runners already qualifying as members of a team) in each age and gender classification from eighteen of the Regional Associations qualify for OFSAA.. Each qualifying team may enter five runners into the competition. This qualification structure results in a maximum of 260 competitors in each event of the championships.
The OFSAA championships consist of six separate races, one for males and one for females in each of three age categories:
Midget: individuals who were less than 14 years of age on the first day of January of the year in which the competition is held and who are enrolled in the ninth grade
