Omer Léger was born in Gardner, Massachusetts and studied at St. Joseph's College in Memramcook, New Brunswick.
He served as provincial secretary until the 1974 election, where he was re-elected in the Kent South riding,[2] when he added minister of Fisheries to his portfolio.
Léger made a comeback in the 1982 election, again in the Kent South riding and defeating Bertin Leblanc.
He rejoined the cabinet as minister of Tourism[3] and served in that role until his and his party's defeat in the 1987 when the Liberals swept every seat in the province.
Léger ran unsuccessfully as a Progressive Conservative in the 1988 federal election in the riding of Beauséjour.
