Bélanger was elected in the general election in 1959 winning in Windsor—Sandwich, a riding which had been held for fifteen years by William Griesinger who had been discredited in a financial scandal in 1958.^[3] Bélanger was re-elected in the general elections in 1963. During his first term in office, he served on as many as eight Standing Committees, simultaneously.

A community park in the west end of Windsor, Ontario, was named in his honour in recognition of his public service.
