Mason Flesch Bio
Mason Flesch is a Canadian rugby union player who plays as a flanker for the Toronto Arrows of Major League Rugby (MLR) and represents the Canadian national team. Standing 1.96 m (6 ft 5 in) tall and competing at approximately 105 kg, he combines the size of a modern forward with the mobility expected of a back-row player. He made his senior debut with the Arrows in 2021 and broke into the senior Canadian squad for the 2023 Rugby World Cup qualifiers.
Early Life and Background
Mason Flesch was born on 18 November 1999 in Cobourg, Ontario, Canada. Cobourg is a small town on the north shore of Lake Ontario, and the region has a long tradition of community rugby that runs alongside its more visible hockey culture. Growing up in this environment gave Flesch early exposure to contact sport, and he gravitated toward rugby as a teenager.
Details about his parents and formal education are not publicly documented in available sources, but his pathway through age-group rugby in Ontario was the typical route for Canadian players of his generation. The province’s youth and club systems gave him a steady stream of representative opportunities as he matured physically, setting the stage for higher honours.
Path to Professional Rugby
Flesch’s progression to the professional level was marked by selection to Canada’s Under-20 setup in 2019. Playing for Canada U20 gave him international experience against other tier-one and tier-two age-group programs and helped him develop the defensive technique and breakdown work that define a modern flanker. That same campaign effectively served as his audition for senior rugby.
Two years later, in 2021, he signed his first professional contract with the Toronto Arrows, the Canadian franchise in Major League Rugby. The move to MLR placed him in a full-time training environment alongside experienced international forwards, accelerating his development and exposing him to the tactical demands of professional rugby union.
Mason Flesch Career
Early Career (2019–2021)
Flesch’s first taste of representative rugby came with Canada U20 in 2019, where he featured as a flanker during the World Rugby U20 Championship cycle. The tournament schedule pitted him against established age-group sides and offered a clear benchmark for where his game stood relative to his peers.
After returning from the U20 program, Flesch continued to develop in the Canadian club system before earning his MLR opportunity. His combination of height, reach, and breakdown work convinced the Toronto Arrows that he was ready for senior rugby, and he signed ahead of the 2021 season.
Toronto Arrows Era (2021–Present)
Flesch made his professional debut for the Toronto Arrows in the 2021 Major League Rugby season. MLR offered him a full calendar of high-level matches, including fixtures against American and international opposition, and he quickly established himself as a regular in the Arrows’ back row. His lineout presence, tackling work, and ball-carrying around the contact area became valuable assets for the franchise.
Across the 2022, 2023, and 2024 campaigns, Flesch continued to grow into one of the more consistent Canadian flankers in the league. As the Arrows’ roster evolved, his role expanded from impact player to dependable starter, and he remained a fixture of the team’s weekly selection. The stability of his environment in Toronto allowed him to refine his craft in both attack and defence.
Canada National Team (2021–Present)
Flesch’s international breakthrough arrived in the 2023 Rugby World Cup qualifiers, where he earned his first cap for the senior Canadian side. The qualifying pathway, which feeds into the global Rugby World Cup, is one of the most demanding stretches of the international calendar, and his selection reflected the form he had shown in MLR.
Since that debut, Flesch has remained part of Canada’s broader senior squad, contributing to test matches and tournament play as the national team continues its build toward major events. His dual role with the Arrows and Canada has positioned him as one of the country’s emerging back-row options.
Driving Style and Strengths
At 1.96 m and around 105 kg, Flesch brings the physical profile of a modern ball-carrying flanker. He is effective at the collision point, useful in the lineout, and disciplined in his tackling. His background in Canadian age-grade rugby, combined with several seasons of professional rugby with the Arrows, has given him a balanced skill set suited to both the tight exchanges and the wider channels.
Notable Events and Milestones
Flesch’s senior international debut in the 2023 Rugby World Cup qualifiers stands as the defining milestone of his career to date. Reaching that stage within two years of signing his first MLR contract underscores the speed of his rise, and his continued presence with both the Arrows and Canada points to a player with a significant runway ahead.

Mason Flesch Career Highlights
Mason Flesch’s career highlights center on three confirmed milestones: his selection for Canada U20 in 2019, his professional debut for the Toronto Arrows in the 2021 Major League Rugby season, and his senior Canada debut in the 2023 Rugby World Cup qualifiers. Together, those steps trace a four-year arc from age-group international to senior national team player.
Toronto Arrows Highlights
Since joining the Toronto Arrows in 2021, Flesch has been a regular member of the team’s back row. The franchise has provided him with consistent game time in MLR, where he has been able to test himself against established American, Fijian, and Samoan imports. He has continued to feature prominently as the Arrows build their roster around a core of Canadian players.
International Highlights
Flesch’s senior international career is anchored by his 2023 Rugby World Cup qualifier debut for Canada. While detailed match-by-match statistics for that campaign are not fully documented in available sources, his inclusion in the squad marked him as a forward considered part of the national team’s long-term planning.
Mason Flesch Family
Family Background and Rugby Lineage
Publicly available sources do not provide detailed information about Mason Flesch’s parents or broader family. There is no widely documented rugby lineage associated with his family name, and his rise appears to have been built primarily through the standard Canadian age-grade and club pathway rather than family connections in the sport.
Personal Life
Details about Mason Flesch’s marital status, spouse, or children are not publicly documented in available sources. Based in Ontario, he continues to balance his commitments with the Toronto Arrows in Major League Rugby and his duties with the Canadian national team.
2025 Season Performance
Heading into the 2025 Major League Rugby season, Mason Flesch remains a key part of the Toronto Arrows’ forward pack. The franchise has continued to build around a core of Canadian players, and Flesch’s experience in both MLR and the Canadian national setup makes him a logical focal point of the team’s back-row rotation. His familiarity with the Arrows’ systems, developed over multiple seasons, should allow him to play with confidence from the opening weekend.
On the international stage, 2025 represents another important year for Canada as the national team prepares for the next Rugby World Cup cycle. Flesch’s senior debut in the 2023 Rugby World Cup qualifiers positioned him well for further selection, and his continued form with the Arrows will be closely watched by the national coaching staff. The combination of club consistency and international opportunity gives him a clear platform to build on his early caps.
Looking ahead, the outlook for Flesch in 2025 is one of consolidation rather than breakthrough. He is no longer a debutant, and the focus shifts to producing consistent performances week to week in MLR while expanding his role with Canada. If he maintains his current trajectory, he is well placed to remain a fixture of both the Arrows’ starting lineup and Canada’s senior match-day squad throughout the year.
