The Congregational Union of Canada is a Christian organization that represents Congregationalist churches across Canada. Founded in the 19th century, it aims to support local congregations in their mission and ministry. The Union promotes cooperation among its member churches and provides resources for spiritual growth and community outreach. The Union is part of the broader United Church of Canada, which formed in 1925 when several Protestant denominations united. While many Congregational churches joined this new denomination, some chose to remain independent and continue their traditions under the Congregational Union's guidance.
