CurlON (formerly the Ontario Curling Association) is the governing body of curling in Southern Ontario. Northern Ontario is governed by the Northern Ontario Curling Association (NOCA). The CurlON sends a team to represent Team Ontario at all major Canadian Championships. The NOCA sends a separate team to all of these events. CurlON was founded in 1875. It was renamed from the Ontario Curling Association in 2016.
