Alongside the announcement of Moose Jaw as host in November 2013, it was announced that the tournament would expand to 15 teams, including Nunavut being invited to participate for the first time, Yukon and the Northwest Territories receiving separate berths (after having previously fielded a joint team), and Northern Ontario receiving a separate berth from southern Ontario (as has been the case in the Brier).[2]
Ten teams were to advance directly to the main draw. The remaining would compete in a pre-tournament qualifier, with the top two teams advancing to the main draw.[2] The team who finishes last in the round robin round of the main draw would be relegated to the pre-qualifier in the following year's tournament.[3]
Nunavut would decline its invitation to the Scotties and Brier for 2015, with the pre-qualifier thus reformatted to use a play-in game[4][5]
After winning the 2013 & 2014 Scotties, Rachel Homan returns again as skip of Team Canada, this time with a new teammate in Joanne Courtney at second. She replaces Alison Kreviazuk who moved to Sweden to be with her partner, Fredrik Lindberg. Courtney played in the 2014 Scotties for Alberta's Val Sweeting rink who returns with a new third in Lori Olson-Johns. They were the silver medalists last year after having lost to Homan in the final. After missing the Scotties last year for the Olympics, where she received a gold medal, Jennifer Jones and her team from Manitoba look to capture her fifth Scotties title. The other favourite is Team Stefanie Lawton, representing Saskatchewan. Although they have never won the Scotties, they have placed 4th four times in previous Scotties tournaments. They are also three-time Canada Cup winners, four-time Grand Slam winners, and are playing on home ice in Saskatchewan.
The pre-qualifying competition consisted of a single round robin between the three teams; the two teams with the best records advanced to a play-in game on February 14, whose winner advanced to the main draw.
