Catherine Dubois is a Canadian ice hockey forward from Quebec City, currently playing for Montréal Victoire in the Professional Women's Hockey League (PWHL). She developed through boys’ hockey until age 15, then played for the Cégep Limoilou Titans before joining the university ranks. At the university level, she starred with the Montréal Carabins, achieving 62 points over 94 games and contributing to conference championships and a national U SPORTS title in 2015–16. Despite a serious kidney-related health setback early in her Carabins career, she returned to the ice — underscoring her resilience and commitment to the game.

Transitioning to professional women’s hockey, Dubois spent time with the former Pro Hockey Federation’s Montréal Force and with the regional women’s association before joining Montréal Victoire after the PWHL’s formation. As of the 2025 season, she re-signed with Victoire and has posted eight goals and seven assists over her first 45 league games. Most notably, she scored the series-equalizing, fourth-overtime goal in May 2025 — the deciding tally in the longest game in PWHL history.

On the international front, Dubois represented Canada at the U18 level, including at the 2012 and 2013 IIHF U18 Women’s World Championships, where Canada won gold. She also contributed to Canada’s program at the Universiade level, earning a silver medal. Her early success internationally and steady professional growth reflect a player defined by perseverance, leadership, and clutch performances.
