The club was founded in 1971 as the
Waterloo Minor Soccer Club. In 2011, the club rebranded as
Waterloo United. In 2020, the team was to begin play with a U21 team in the League1 Ontario Reserve Division, The club also added a team in the
League1 Ontario women's division for the 2021 season. The city of Guelph also added
men's and
women's teams in 2021, setting up a natural local rivalry for the two clubs. However, due to the
COVID-19 pandemic, Waterloo deferred their entrance to the League1 Ontario top division until 2022. In 2022, the club struck an affiliation agreement with German club
Borussia Dortmund. As part of the agreement, the League1 Ontario teams will compete under the name BVB IA Waterloo. In 2025, the club returned to using the Waterloo name for their League1 Ontario teams, while the youth sides retained the BVB branding. In March 2026, Waterloo United announced a partnership with Kitchener SC to jointly support the Ontario Premier League (re-branded from League1 Ontario in 2026) team, with the team to announce a re-brand in 2027 (they will continue to use the Waterloo United name for 2026 - both clubs would still operate their own separate youth programs). ==Seasons==
