Mennonites from Russia arrived at the Erb Street Mennonite Church, Waterloo, in July 1924. That year these Mennonites met for worship in homes in the area including New Dundee, St. Jacobs, and Baden. In 1925 the congregation was organized as the Molotschna Mennonite Brethren Church of Kitchener with 18 charter members. They met to worship alternately in St. Jacobs and at the Bethany Mennonite Church in Kitchener. Later in 1925 they settled in rented facilities in Kitchener. In 1935 they purchased their own meeting house in Kitchener. The membership was 178 in 1942. This building was used until 1953 when the present meeting house was built in Kitchener. In 1953 the membership stood at 356. This building was expanded in 1956. During the 1950s it absorbed members for the Hespeler and New Hamburg congregations which dissolved. From 1955 to 1964 the Ontario M.B. Bible School was located in the new education wing added to the new meeting house. In 1961 the Zion M.B. Church was an outgrowth of this congregation. The membership was 427 in 1961 and 394 in 1967. In 1967 the Waterloo M.B. Church was another outgrowth. In 1971 they again expanded the meeting house building. In 1980 the membership was 450. In the 1980s another congregation was formed in the Kitchener area, the Glencairn congregation. In 2000 the membership stood at 427.
