In the meantime, an interest in religion (which had begun in his youth after a non-religious upbringing) increased and he decided to seek ordination.

He was ordained as an Anglican priest and served in the following positions: Peers spoke English, French, Spanish, German and Russian.

Peers was later confessor to the monastery of the Society of St. John the Evangelist in Boston and Ecumenist in Residence at the Toronto School of Theology.

Rural Saskatchewanians quickly perceived that Peers was their ardent supporter—that the ideals of prairie populism were his own ideals—and that his obvious membership in the Canadian élite was entirely to their advantage.

The life of a prairie bishop is one of endless travel along the highways and byways of the prairie hinterland: in the course of such travels Peers made long and lasting friendships with many members of the Saskatchewan leadership, as with many grassroots Saskatchewanians, and these friendships amply informed the national and worldwide ministry of his primacy.
