Montreal Roses W

Roses FC was co-founded by Quebecer entrepreneurs Isabèle Chevalier and Jean-François Crevier, who bought a licence for a team in the Northern Super League, then tentatively known as Project 8, in July 2023. Chevalier, who gained notoriety as a "dragon" on both the French and French-Canadian adaptations of Dragons' Den, sought a team in the league as a passion project inspired by her advocacy for women's sports; while Crevier, whose companies manufacture and distribute lubricants, sought involvement in the league after news reports covering its establishment piqued his interest. Their acquisition, along with regulatory approval by Canada Soccer, was achieved in May 2024, and the league publicly announced Roses FC and Ottawa Rapid FC as the last two of its six charter members at the espnW Summit Canada shortly after.

During the club's development, Chevalier and Crevier sought advice from former Laval Comets and Canadian national team player Amy Walsh, and former Montreal Alouettes president Patrick Boivin. They appointed former Montreal Alouettes and Montreal Alliance executive Annie Larouche as the first president of Roses FC, and former Juvisy and French national team player Marinette Pichon as its first sporting director. Larouche, who was still an executive with the Alliance when she was nominated, served out the rest of her tenure with the Alliance until the end of the 2024 CEBL season. Pichon had immigrated to Quebec in 2019, following her tenure as Juvisy's general manager, and participated in the local soccer scene prior to her appointment. Pichon appointed Robert Rositoiu, who achieved a League1 Canada treble as coach of A.S. Blainville Féminin in 2022, as Roses FC's first ever head coach. Fifteen investors were secured for the club, some of which were appointed as brand ambassadors under the title of investor-ambassadors.

Roses FC were the last of the six charter members of the league to unveil their branding, and did so at a high-profile event held at Dalhousie Station in Old Montreal on October 8, 2024, attended by around 550 people including Isabelle Charest, Laurent Duvernay-Tardif, members of the Montreal Victoire and Canada men's national soccer team, and various club and league executives and investors. The first player signings were announced a few weeks later – French defensive midfielder Charlotte Bilbault and Canadian goalkeeper Gabrielle Lambert, who both transferred from European clubs to join Roses FC. The club initially found difficulty in securing a long-term tenancy at a venue in Montreal, and adopted a touring model for their inaugural 2025 season, in which their home games were played in various venues.
