In 1908, the Basis of Union was formulated that would eventually lead to the creation of the United Church of Canada in 1925. Coinciding with this spirit of unity, the first Union church (Presbyterian and Methodist) was set up in Melville, Saskatchewan in 1908, followed a short time later by the church in Frobisher. In 1912, a committee of Union Churches approached the national church courts of the Presbyterian, Methodist, and Congregational denominations in order to seek affiliation with the parent churches. This committee formed the nucleus of what would become the General Council of Union Churches of Western Canada. An Advisory Council, with representatives of the Union Churches and the parent churches, was established in 1914 as a means of creating the sought after link between the Union Churches and the parent churches.

The Cooperating committee of Saskatchewan was formed when representatives of the Presbyterian and Methodist Churches met at Regina, May 2, 1911, in order to facilitate cooperative activity in various localities in Saskatchewan. The formation of this Committee paralleled a similar action taken at the national level by the Presbyterian, Methodist and Congregational Churches. After mid-1923, this committee was called the Provincial Committee on Co-operation.

The Provincial Church Union Committee was formed on July 26, 1923, by representatives of the Saskatchewan Methodist Conference and the Presbyterian Synod of Saskatchewan to take preliminary steps to effect Church Union in Saskatchewan. Representatives of the congregational Churches were also invited to be on the committee.

The Joint Committee officially convened in April 1904, in Toronto, bringing together appointed representatives from the Congregationalist, Methodist and Presbyterian Churches, to negotiate church union. Meetings continued through to 1908, when the terms written in the Basis of Union were agreed upon and sent to the negotiating churches, for discussion and approval. By 1912, both the Congregationalists and the Methodists had agreed to the terms. The decision was more contentious for the Presbyterian Church, though in 1916, their General Assembly decided to go ahead with the union.
Between 1916 and 1925, the Joint Committee worked to complete the union and defeat those opposing it, including the newly formed Presbyterian Church Association.

The United Church Woman's Association (W.A.) in Saskatchewan appears to have been formed by the 1950s, or possibly earlier. It primarily operated in local and presbytery-level units before the organization of the national-level Dominion Council of the Woman's Association, in 1940. Efforts of the W.A. generally supported the local church and community, while other organizations focused on education and world mission programs.

In 1962, United Church W.M.S. and W.A. organizations across the country amalgamated to form the United Church Women (U.C.W.). Presbyterial and local groups developed along similar lines to national bodies, becoming local and presbyterial U.C.W. units in January 1962.

The United Church Women (U.C.W.) was formed in 1962, from an amalgamation of United Church Woman's Missionary Society (W.M.S.) and Woman's Association (W.A.) organizations, across the country. Existing Women's Federation (W.F.) groups were also incorporated into the UCW. Local and Presbytery-level groups developed along similar lines to national bodies, becoming local and presbyterial U.C.W. units in January 1962.

In October 2012, Saskatchewan’s U.C.W. Conference Coordinating Committee voted to disband and be replaced by the Women of the United Church of Canada Network. The mandate of the new network included communicating and supporting U.C.W. activities.

The Young People's Union (Y.P.U.) of the United Church and its Conference-level units were organized around 1935, following the recommendation of the Interprovincial Young People's Council (1934). Saskatchewan Conference's Y.P.U. appears to have been formed sometime after the first National Y.P.U. Council, in mid-1935.

In 1965, the United Church Y.P.U. and its constituent Conference- and Presbytery-level groups appear to have been reorganized to form units of Kairos.
