This is to mark the founding of the United Church of Canada, inaugurated on 10 June 1925 in Toronto, Ontario. The Methodist Church, Canada, the Congregational Union of Canada, and 70 percent of The Presbyterian Church in Canada entered into a union. Also joining was the small General Council of Union Churches, centred largely in Western Canada.
