In 1925, all the Methodist churches in Canada, virtually all the Congregationalist churches, and approximately two-thirds of the Presbyterian ones joined to form the United Church of Canada. This amalgamation culminated a number of unification movements within the three denominations, which had earlier produced the Presbyterian Church in Canada (1875) and the Methodist Church (1884). The organization of the United Church is presbyterial, and membership in its boards is composed of an equal number of lay and clergy representatives. Individual congregations are governed by sessions, and these are grouped into regional presbyteries which exercise supervision over ministers and pastoral charges. Presbyteries are in turn grouped as conferences, with powers to ordain clergy. Legislation and policy are determined by the Church's General Council.
