It is one of the five Grand Slams and four "majors" on the men's and women's curling tours.

A women's event was introduced in the 2014–15 curling season.

In 2021, when it was supposed to be held outside of Canada for the first time, it was going to just be called the Open.

In 2023, the event was named the Co-op Canadian open for sponsorship reasons.

The event features 16 men's and women's teams.
