Minnesota will take on Brampton in Sunday's final after the Thunder beat the Montreal Stars 3-2 in the other semifinal game.

Potter opened the scoring in the first before Keys doubled the Minnesota lead on a redirection in the second.

Fisher added another on a breakaway as the Whitecaps led 3-0 after two. Sommer West scored for Mississauga in the third, but the Chiefs would get no closer.

Earlier on Saturday, Brampton's Bobbi Jo Slusar's second-period goal proved to be the winner for the Thunder.

With 45 seconds remaining in the period, Slusar took a Jayna Hefford pass and beat Montreal goaltender Jenny Lavigne with a high shot.

Hefford and Gillian Apps had the other goals for the Thunder.

Noemie Marin and Caroline Ouellette replied for Montreal, who came in as the defending champion.
