The tournament features the top "club level" curlers from every province and territory in Canada, plus Northern Ontario.

Each province and territory holds a series of playdowns where only one team per curling club is allowed an entry.

This means that top curling teams are barred from entry.

Teams can only have one player who has played in a provincial men's, women's or seniors event that season or the previous season or in a Grand Slam of Curling event that year or in the previous year.

Beginning in 2023, the winning teams will play the winners of the United States Curling Club Championships in the Everest North American Curling Club Championships.
