From 2021, the World Mixed Doubles Curling Championships (WMDCC) will have a relegation for bottom ranked teams per the WCF Rules. Top ranking teams in the World Mixed Doubles Qualification Event (WMDQE) will move up into the World Mixed Doubles Event and bottom ranked teams from the WMDCC will be required to re-qualify by placing in the top ranked teams of the WMDQE. Teams ranking between 1 and 16 will remain in the WMDCC event for the following year.
