In 1916, a joint meeting of the Managers of the Presbyterian Church in Roblin and the Official Board of the Methodist Church in Roblin came forth with a recommendation for church union in the Roblin District. The congregations affected by this were Roblin, Tummel, Cromarty and Cranbrook. The arrangement was formalised after a mass meeting of the congregations of both denominations. By the time The United Church of Canada was created in 1925, it was apparent that the Roblin Union Church was too small to meet the needs of the community. That year the first of several extensive renovations of the church building were begun (the others took place in 1958, 1960 and 1974). Lay Associations of the Union and later United Church congregations included the Union Ladies Aid, created from an amalgamation of the Presbyterian Ladies Aid (formed in 1905) and Methodist Willing Workers (formed in 1909). A Roblin Union Woman's Missionary Society was also organised in 1917. In 1947, an 'Evening Guild' of the Ladies Aid was created. All these groups joined together to form the Knox United Church Women in 1962. Groups for young people included Hi-C, C.G.I.T., Sigma-C, Tyros and Messengers.
