Coronach Pastoral Charge was formed as a United Church charge sometime between 1926 and 1932, part of Assiniboia Presbytery and consisting of preaching points at Coronach, Clydesdale and Hart. In the early 1940s, Buffalo Gap was also part of the charge, from what had previously been Buffalo Gap Pastoral Charge (ca.1926, with Caron, Beaver Creek and Dry Forks). By 1951, the charge had joined with Rock Glen Pastoral Charge to form Rock Glen - Coronach Pastoral Charge, with points at Rockglen, Coronach, Fife Lake, Hart and Clydesdale. The charges had separated again by 1958. As of 1962, Coronach Pastoral Charge consisted of the Coronach, Clydesdale and Willow Bunch congregations.

Around 1968/1969, Coronach combined with Rockglen Pastoral Charge (including Killdeer and Fife Lake) to create the new Borderlands Pastoral Charge.
