Ontario Scotties Tournament of Hearts
The Ontario Scotties Tournament of Hearts is the Ontario provincial curling championship for women's curling. The tournament is run by CurlON, the curling association for Southern Ontario. The winning team represents Southern Ontario at the national Scotties Tournament of Hearts.
National champions are indicated in bold. Teams from Northern Ontario are indicated in italics, as prior to 2015, Northern Ontario did not have their own provincial championship. National champions get an automatic bye into the following years' national championships, so they cannot defend their provincial championship. A national championship has been held since 1962, although the provincial women's championship has been held since 1956.Winners
