Stu Sells Living Waters Collingwood Classic

The Stu Sells Living Waters Collingwood Classic, formerly the Stu Sells Cookstown Classic, and the CookstownCash presented by Comco Canada Inc. is an annual curling tournament that was part of the World Curling Tour, the highest-level curling tour in the world. The event was introduced in 2012 and was held on the first weekend in November, at the Cookstown Curling Club in Cookstown, Ontario. The event was moved to the Collingwood Curling Club in Collingwood, Ontario in 2023. Originally just part of the Ontario Curling Tour, it was part of the World Curling Tour from 2014 to 2017. After a five-year pause, the event returned in 2022 as part of the Stu Sells series.

Team Heather Heggestad was the last women's team to win the event, in 2016.
