The rest of the field will be determined in upcoming provincial championships.
The Canadian Curling Association has altered the format for both the Scotties and the men's championship, the Tim Hortons Brier, to make it a true national championship with all provinces and territories represented.
The Brier will feature a defending champion Team Canada and the Scotties will have a Northern Ontario representative for the first time so that the men's and women's national championships mirror each other.
Galusha, Koltun, Horgan and a representative from Nunavut will square off in a pre-qualification tournament with the winner advancing to the main draw of the Scottties.Suggest a correction
