The Toronto Argonauts are a professional Canadian football team competing in the East Division of the Canadian Football League (CFL), based in Toronto, Ontario. Founded in 1873, the team is the oldest existing professional sports team in North America still using its original name, as well as the oldest-surviving team in both the modern-day CFL and East Division. The team's origins date back to a modified version of rugby football that emerged in North America in the latter half of the 19th century. The Argonauts played their home games at Rogers Centre from 1989 until 2016, when the team moved to BMO Field, the fifth stadium site to host the team.
