[21][22] In February 2023, Collins joined the Canada women's team as a training player for the 2023 SheBelieves Cup.

[24] After not making the Canadian roster for the 2023 FIFA Women's World Cup, where the team would go on to suffer a disappointing group stage exit, Collins was called up for the team's next fixtures in September, a two-leg CONCACAF Olympic qualification playoff against Jamaica.

"[25] Despite having only played fourteen minutes in her lone prior international appearance, with Canada seeking to reorganize following the World Cup, coach Bev Priestman opted to start Collins in the first match, citing her strong camp performance.

[26] This was widely cited as a "surprise" move, but Collins' performance was generally assessed positively, and she ultimately started both matches, which saw Canada defeat Jamaica and qualify for the 2024 Summer Olympics.

[27][28] She was originally named to the squad for the Olympics, but was forced to withdraw after suffering a fractured leg in a warmup match ahead of the tournament.
