[7] They played their inaugural match on April 29, 2018 against North Mississauga SC at home, which they lost by a score of 1–0.

[9] They improved to a 3rd-place finish in the 2019 season, but had a very poor showing in the playoffs where they lost 15–0 to FC London on aggregate in the semi-finals over the two-game series, due to being unable to field many of their best players, who missed the series due to college and university commitments,[10] thereby having to rely on many youth players instead.

[13] In addition, they advanced to the League1 Canada Women's Interprovincial Championship for 2022, as NDC Ontario was unable to compete due to player unavailability,[13] where they finished in 3rd place, following a defeat to PLSQ side AS Laval in a penalty shootout in the semi-finals,[14][15] before defeating League1 British Columbia side Varsity FC in the third-place match in another penalty shootout.

[16] In 2023, after finishing 4th in the regular season, they won the women's league championship defeating NDC Ontario in the playoff final.
