Toronto Arrows

2017–2018: Ontario Arrows

The team was founded as the Ontario Arrows in 2017 with the intent of joining the Major League Rugby (MLR) competition for the 2019 season. The Arrows debuted September 9, 2017, in a match against the Glendale Merlins losing 41–7.

In spring 2018, the Arrows played a six-game exhibition schedule against the Houston SaberCats, Rugby United New York, Utah Warriors, and Boston's Mystic River Rugby Club. The schedule was extended to include games against the Canada Selects. The Arrows' 2018 home opener was a decided victory over the Mystic River Rugby Club.

In July 2018, the Arrows announced that MLR had granted them exclusive rights to negotiate for a franchise in Ontario. In November 2018, MLR announced that the Arrows had joined the league for the 2019 season. At the same time, the Ontario Arrows changed their name to the Toronto Arrows. The ownership group is led by Bill Webb, partner and chief investment officer at Waypoint Investment Partners. The ownership group also includes the former general manager of the Toronto Maple Leafs Brian Burke, Boat Rocker Sports (a division of Boat Rocker Media), Duncan McNaughton, an assistant coach with the Canadian women's team and the Queen's University men, Kevin Reed of AR3 Capital, and John Ferraro of Mass Marketing Inc. As MLR operates as a single entity league, the ownership group purchased an equity stake in the league, at the cost of a few million dollars, and received operating rights to a franchise in the Toronto market.

2019–2021: First MLR seasons

In the 2019 season the team split its home games between Alumni Field of York University and Lamport Stadium in its inaugural 2019 MLR season.

After playing only five matches in 2020, the Arrows ceased play, along with the rest of the league, as the COVID-19 pandemic began. Due to border crossing concerns related to the COVID-19 pandemic during the 2021 season, the Arrows temporarily relocated to Marietta, Georgia, to share Rugby ATL's facilities at Lupo Family Field.

2022–2023: Final seasons

For the 2022 season, the Arrows hosted their game against the LA Giltinis at Starlight Stadium in Langford, British Columbia, marking the first MLR regular season game to be held in the province. The remainder of their home games were played at the renovated York Lions Stadium, over 1,000 days after the team's previous home game in Toronto.

On August 30, 2023, the Arrows announced the passing of president and general partner, Bill Webb. Bill Webb's passing resulted in an outpouring of support from across the rugby world, including players, teams, leagues and foundations. On November 27, 2023, it was announced that the Arrows would not compete in the 2024 MLR season.
