The USA will face Costa Rica, the second-place team in Group B, in Friday's semifinals for a berth to the 2024 Under-20 Women’s World Cup.
Mexico and Canada meet in the other semifinal. The third berth in the 2024 World Cup from Concacaf will go to the winner of Sunday's third-place game.
The final two days of the tournament have been moved from Thursday and Saturday to Friday and Sunday because of the delayed start to the tournament because of bad weather.
Ally Sentnor led the USA with two goals to give her four goals in the tournament, tied with Madeline Dahlien as the team’s leading scorer.
Gisele Thompson, Alyssa Thompson's younger sister, and Dahlien also scored for the USA. Its fifth goal was a Canada own goal forced by Onyeka Gamero.
Dahlien tallied a hat trick in the 4-0 win against Jamaica in her U-20 debut. The USA opened play with a 6-0 win over Panama.
