Moose Jaw Minto Pastoral Charge was formed as a new United Church charge in 1925, from what had previously been the Presbyterian Moose Jaw Minto Pastoral Charge.

Caron Pastoral Charge was formed as a new United Church charge in 1925, containing preaching points at Caron, Knox [Grayburn?] and Summerside. Later points included Wesley and Boharm (ca.1960). Around 1969, the charge divided and St. Andrew's United Church (Caron) was added to Moose Jaw Grace Pastoral Charge, creating the new Moose Jaw Grace-Caron Pastoral Charge. Boharm and Wesley briefly formed their own Boharm-Wesley Pastoral Charge, before dividing (ca.1970), with Boharm joining Moose Jaw Minto Pastoral Charge. Wesley would be officially discontinued, ca.1971. The Grace-Caron Charge would also later dissolve and Caron church would join Mortlach Pastoral Charge.
