The couple confirmed their relationship publicly in May 2026 after appearing together during events associated with the Formula 1 Canadian Grand Prix in Montreal.
According to Billie, a Quebec entertainment publication, speculation about their relationship began circulating earlier in 2026 after fans noticed similarities in their social media activities.
In April 2026, Greaves appeared in photographs alongside the wives and girlfriends of Los Angeles Kings players. She wore a jacket displaying Joseph’s jersey number, attracting attention from hockey fans and entertainment media.
On May 27, 2026, Billie reported that Joseph and Greaves had shared photographs together from Formula 1 celebrations in Montreal, publicly establishing their romantic relationship.
The couple appeared at social events and shared photographs from the weekend, including moments at the Ritz-Carlton Montreal.
Although their relationship became public in May, the exact date they started dating has not been reliably established.

In September 2026, Greaves announced that she was relocating to Edmonton, Alberta, to be closer to Joseph following his move to the Edmonton Oilers.
The news was reported by Billie on September 11, 2026, after Greaves shared an update with her social media followers.

Greaves explained that relocating involved significant changes, including organizing her belongings, adjusting her work schedule, and saying goodbye to familiar surroundings.
The move represented an important milestone in their relationship as they began a new chapter together in Edmonton.
Is Mathieu Joseph Married?
Mathieu Joseph has not publicly announced a marriage.
His relationship with Emy-Jade Greaves was documented in 2026, but reliable reports identify her as his girlfriend rather than his wife.
There is no verified wedding announcement or marriage date involving the couple.
Therefore, claims that Mathieu Joseph is married should not be presented as established facts without credible confirmation.
Does Mathieu Joseph Have Children?
There is no publicly verified information confirming that Mathieu Joseph has children.
The Edmonton Oilers forward has not made a widely documented announcement about becoming a father, and official NHL and Hockey Canada biographies do not identify any sons or daughters.
Although Joseph has shared aspects of his family life through interviews, those discussions have primarily concerned his parents, younger brother, and childhood experiences.
Likewise, publicly available reporting about his relationship with Emy-Jade Greaves does not establish that the couple has children together.
Consequently, his parental status remains unconfirmed through reliable public sources.
Mathieu Joseph’s Parents
Mathieu Joseph was born to Frantzi Joseph and France Taillon in Laval, Quebec.
His parents raised him and his younger brother, Pierre-Olivier, in the Montreal region, including Chambly, Quebec.
The family has Haitian and French-Canadian roots. Frantzi comes from a Haitian family, while France is from Quebec.
Both parents encouraged their children to participate in different sports while emphasizing education, respect, discipline, and personal development.

Frantzi Joseph is Mathieu Joseph’s father and one of the most important influences on his early hockey development.
Frantzi has Haitian roots and moved to Montreal with his family when he was approximately two years old.
He developed a passion for hockey during his youth and continued playing recreationally as an adult.
Although Frantzi did not establish a professional NHL career, he played organized hockey and later coached his sons during their childhood.
In an interview with Hockey Le Magazine, Mathieu recalled accompanying his mother and younger brother to watch their father participate in recreational hockey games.
The brothers enjoyed watching Frantzi compete and developed an early interest in following his example.
Frantzi also helped introduce his sons to organized hockey and supported their participation in minor leagues.
However, he and France were careful not to pressure their children into pursuing professional careers.
In interviews with Le Journal de Chambly, Frantzi explained that his priority was ensuring his sons enjoyed hockey and developed into responsible individuals.
The family encouraged Mathieu and Pierre-Olivier to make their own decisions about their sporting futures.
Frantzi also emphasized the importance of respecting others, an especially significant lesson because his sons sometimes experienced racial discrimination while growing up.
In a June 2023 radio interview with 98.5 Montreal, the family discussed how Frantzi had helped his sons understand and respond to stereotypes and prejudice.
His guidance helped Mathieu develop the confidence to speak publicly about diversity and inclusion in professional hockey.

She grew up in Quebec and attended the Université de Montréal, where she completed a master’s degree in speech-language pathology.

In a March 2024 interview with Le Journal de Québec, she discussed her upbringing, education, and experiences raising two sons who eventually became NHL players.
France explained that she and Frantzi wanted their children to experience different activities rather than concentrate exclusively on hockey.
Both sons participated in figure skating during childhood, and Mathieu even won a medal in the sport at the Jeux de Montréal.
They also enjoyed soccer and other recreational activities before eventually choosing hockey as their primary sport.
France believed participation in different sports helped her children develop useful skills and maintain a balanced childhood.
She has also emphasized the importance of respect and understanding differences between people.
During interviews about racial discrimination in hockey, France described conversations she had with her sons about prejudice and the importance of responding with confidence and dignity.
She remained a strong supporter as both sons advanced through junior hockey and into the NHL.
In January 2024, France accompanied Mathieu during an Ottawa Senators mothers’ trip to Montreal, describing the experience as an opportunity to spend valuable time together during a demanding hockey season.

They also discussed finding accommodation together in St. Louis and making room for visiting family members.
The Joseph Brothers Play Together for the St. Louis Blues
One of the family’s most memorable sporting moments occurred in October 2024, when Mathieu and Pierre-Olivier became teammates with the St. Louis Blues.
Mathieu had been traded to St. Louis from the Ottawa Senators in July 2024, while Pierre-Olivier joined the organization through free agency.
On October 17, 2024, their parents attended a Blues home game against the New York Islanders and watched the brothers play together for the first time in the NHL.
Two days later, the brothers combined on an important scoring play against the Carolina Hurricanes.
Pierre-Olivier contributed to the sequence that resulted in Mathieu scoring the Blues’ first goal of the game.
Television cameras captured Frantzi and France celebrating enthusiastically in the stands.
