Canada dominated throughout, dictating possession and creating numerous chances, extending its record to 12-0 against Caribbean opposition in the CONCACAF women's championship and outscoring its foes 93-1. Canada improved to 3-0 against Trinidad in the tournament with its first victory since 1994.

Trinidad fell to 1-2-11 against North American teams in the competition.

Tancredi twice had goals disallowed for offside in final 10 minutes of the first half, the first of which appeared onside according to television replays.

Josee Belanger foreshadowed Canada's domination in the sixth minute. Tancredi bore down unmarked on Trinidad keeper Kamika Forbes, who raced off her line to block the initial shot. The ball bounded left to Belanger, whose left-footed shot from the middle of the area curled off the near post.

The Canadians repeatedly threatened, with Christine Sinclair redirecting Belanger's cross wide of the post in the 48th, and both Sinclair and Tacredi shooting in rapid succession from the edge of the six-yard box that Forbes blocked at the left post in the 60th.

Canada finally finished a chance when Rhian Wilkinson ran onto a ball out of midfield on a counter, and looped a ball into Tancredi racing diagonally into the penalty area. Tancredi took one touch, held off defender Anyana Russell and right-footed a shot under Forbes from the edge of the six-yard box.

It continued to threaten the Trinidad net when Jonelle Filigno raced in unamarked only to shoot wide in the 74th from 13 meters, and in the 80th when Kaylyn Kyle's shot hit the side netting.

Trinidad, which began the game with four teenagers in its starting lineup, had little possession and even fewer shots, needing 32 minutes before it managed to earn a corner kick.

The closest it came to a goal was in the 62nd minute when Akeela Mollon's corner kick curled just over the crossbar.

Both sides suffered injuries with Canada defender Emily Zurrer forced off the field for nearly six minutes to bandage a cut over her left eye - suffered in a goalmouth scrum during a corner kick, and Trinidad defender Katrina Meyer required to leave the game in the 25th with what appeared to be a sprained ankle.
