Plamondon supported the Chrétien government's choice of Dyane Adam to become Canada's official language commissioner in 1998, saying that she would be "tougher" than her predecessor Victor Goldbloom (whom he nonetheless acknowledged had done good work on education matters). He endorsed Adam's criticism of the Chrétien government in 2000, when she wrote that it was not sufficiently committed to defending official bilingualism. Plamondon strongly opposed the Clarity Act legislation introduced by intergovernmental affairs minister Stéphane Dion in 1999, arguing that it would create confusion in any future referendum on Quebec sovereignty.
