Mathieu Choinière was born on 7 February 1999 in the province of Quebec, Canada. He developed through the Canadian youth pathway and made his professional career primarily with CF Montréal in MLS, where he became a recognisable wide attacker in the club's system. His pace and ability to run in behind defensive lines made him a useful threat on the counter in MLS competition.
He was a regular presence in CF Montréal's squad through their MLS seasons, contributing to the club's performances in league and CONCACAF Champions League. His Quebec background adds to the cultural diversity within the Canadian squad and connects the French-Canadian football community to the national team's trajectory.
For Canada, Choinière has been part of the extended national team environment, receiving call-ups in Gold Cup and Nations League cycles. He represents the depth of Canadian attacking talent that has developed around the core of the golden generation, with CF Montréal serving as one of the key clubs developing Canadian internationals.
A wide forward who thrives on pace and directness, Choinière's contributions to CF Montréal across MLS seasons have kept him relevant in the national team picture as Canada builds its squad depth heading into the 2026 home World Cup.
