Canada's Rachel Homan finishes first in the preliminary round at the Ford Women's World Curling Championship with a 9-6 win over Sweden.
The Ottawa Curling Club team caps the round robin with a 10-1 record followed by Switzerland's Binia Feltscher at 9-2.
The two countries meet Friday evening in a playoff game between the top two seeds.
The winner books a ticket to Sunday's gold-medal game. The loser drops to Saturday's semifinal.
Russia's Anna Sidorova, Sweden's Margaretha Sigfridsson and South Korea's Ji-sun Kim all finished 8-3.
The top four teams advance to playoffs, so Russia will face the winner of a tiebreaker between Sweden and South Korea in the other playoff game.
Homan's team won the bronze medal at last year's world championship in Riga, Latvia.
