Richmond Hill United Church, at 10201 Yonge Street, is a designated heritage building in the town of Richmond Hill, Ontario, Canada. The main body of the building dates back to 1880, then as Richmond Hill Methodist Church, with later additions built in 1932 and in 1957 (Christian Education building). Originally the Methodist Church, it was renamed the United Church in 1925 when the Methodists, the Congregationalists, and the Presbyterians entered into a union. The church is, and always was, first and foremost a place of worship. In its early days there is a possibility that, aside from general church related uses, it could also have served as a Sunday school. With time and with the extensions the functions expanded in range. The church began to gain recognition not only as a religious venue but also as an important community marker. This church has a strong social justice orientation, and became an affirming ministry in June 2013. Currently, the church has tenants that use parts of its space, which include a dance school, a drama group, ESL training, and a math enrichment program. Occasionally the building is also used as a place for committee meetings and as a gathering space for community groups concerning cultural, social, or other issues.
