Outside of the Grand Slams, Miskew and her team won the 2nd Royal LePage OVCA Women's Fall Classic.

This gave the rink a 101 record, 2nd behind Manitoba who went undefeated. However in their first playoff game against Jones, the Homan rink made amends by defeating Jones 85. This put the Homan team in the final, where they faced Jones once again, and this time would beat them again, by a score of 96. With the win, the Homan rink becomes the first Ottawa-based team to win the Canadian women's curling championship. The win earned Miskew and her team the right to represent Canada at the 2013 World Women's Curling Championship in Riga, Latvia. At the World championships, the Homan rink led Canada to an 83 round robin finish, which put them in third place. In the playoffs, they beat the United States (skipped by Erika Brown) in the 3 vs. 4 game, but they then lost to Scotland (skipped by Eve Muirhead in the semi-final, after Homan missed her last shot of the game, jamming a double takeout.
