After Vaugeois resigned in 1985, Philibert won a by-election in the same district. He was re-elected six months later against newly appointed Cabinet Member Rollande Cloutier and was re-elected in 1989. He served as a Parliamentary Assistant from 1985 until the 1994 election in which he was defeated by PQ candidate Guy Julien.
