Eatonia Pastoral Charge was formed as new United Church charge in 1925, part of Kindersley Presbytery and consisting of Eatonia and La Porte preaching points, as well as Bailey (from 1926). As of 1951, the charge was listed under Rosetown Presbytery, with points at Eatonia, Glidden, Laporte, Mantario and Rankin. By 1962, only Eatonia and Mantario remained in the charge.

Around 1976, Eatonia and Mantario (from Eatonia PC) combined with Marengo, Alsask and Flaxcombe (from Marengo PC) to form Prairie Neighbours Pastoral Charge. The new charge lasted until January 1, 1983, when Eatonia-Mantario Pastoral Charge was established (alongside Marengo Pastoral Charge).
