Leask Pastoral Charge was formed as a United Church charge in 1925, part of Prince Albert Presbytery and consisting of Leask, The Reserve, and Kilwinning. As of 1932, the re-named Blaine Lake and Leask Pastoral Charge (just Blaine Lake Pastoral Charge by 1936) included Craigmore, Mt. Olive and Carleton Union points. By 1958, the name had returned to Leask Pastoral Charge and by 1962, it had become Leask - Shell Lake Pastoral Charge, with Blaine Lake, Craigmore and Mildred appointments.

Around 1965, the charge returned to the name Leask Pastoral Charge, with points at Blaine Lake and Craigmore. The point at Shell Lake moved to Spiritwood Pastoral Charge. By 1972, Leask joined the Shellbrook and Craigmore points to form Shellbrook-Leask Pastoral Charge.
