Softball Ontario has 120,000 softball members across its four Member Associations.
Softball Ontario is the recognized provincial sport governing body for softball in Ontario.
In 1971, Softball Ontario was created, bringing together the three charter member associations (Ontario Amateur Softball Association, Provincial Women’s Softball Association, Ontario Rural Softball Association) to form one provincial body to work for the betterment of softball in Ontario. In 1992, a fourth member association (Slo-Pitch Ontario Association) joined Softball Ontario to complete the softball picture in Ontario.
At present, Softball Ontario is the developmental sector of the sport whereas the four member associations deal with the operational aspects of the sport through regional or zone and provincial championships.
