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.

Hafford Hospital was first built around 1922, by the Missionary Society of the Methodist Church. The first superintendent was the Rev. G. Dorey, who would later become Moderator of the United Church of Canada (successor to the Methodist Church in Canada). Dr. S.M. Scott was the first doctor to serve the hospital, followed by Dr. Rose, who was later joined by Dr. Paulson. The Hafford Hospital Ladies Aid Society, formed 1924, was involved in raising money to support hospital activities. After financial difficulties in the 1930s, the hospital was eventually closed, in 1941, due to lack of funds.

In 1946, the R.M. of Redberry and the Village of Hafford bought the building and its equipment from the Missionary Society, then re-opened it as the Hafford Union Hospital.

Built around 1912, Metropolitan Methodist Church became Metropolitan United Church in 1925 (part of the United Church of Canada). It was later re-named Knox-Metropolitan United Church, with the amalgamation of downtown Regina's Knox United Church and Metropolitan United Church.
