TUMC, which formally organized in 1948 among members of mainly "Russian Mennonite" origin, is now a multicultural congregation that draws people from across the Greater Toronto area.

It aspires to be a family of faith that welcomes people with diverse backgrounds and stories, worshipping together and supporting one another, while following Christ's example in working for peace and justice in a post-modern, urban context.

TUMC shares its multi-use building with two partners, the Mennonite New Life Centre of Toronto and the Toronto New Life Mennonite Church. Local ministries the congregation supports include St. Clair O'Connor Community, the Lazarus Rising homeless ministry, the Ten Thousand Villages Festival Sale, and assistance to refugees.
