The format of the 2011 tournament was different from previous editions. In 2011, with four teams involved, the tournament was changed to be a home-and-away semifinal round and a similar final round between the winners. Toronto, as reigning champions, were assigned the top seed and were matched with Edmonton, who were assigned the fourth seed as newcomers to the tournament. The two remaining teams, Montreal and Vancouver, faced off in the other semifinal.
Match abandoned in the 60th minute due to lightning and unplayable field conditions. Originally scheduled to be replayed on May 26, 11:00 EDT, but was rescheduled as weather conditions prevented the match from being played. The second leg was eventually replayed on July 2, 12:30 EDT, in its entirety starting from 0–0 according to the rules of the tournament.
