Rocheleau was born in
Hull, Quebec, he was a businessman by career. His post-secondary education was at the
University of Ottawa. He became a city councillor in 1967, then mayor from 1974 to 1981. He was elected as a member of the
National Assembly of Quebec in 1981 in
Hull as a member of the
Liberal Party of Quebec. He was again elected to the Assembly in 1985 and became a cabinet minister in Premier
Robert Bourassa's administration. He left provincial politics to campaign in the
1988 federal election in the
Hull—Aylmer electoral district for the national
Liberal party. He served in the
34th Canadian Parliament until he left the party on 2 July 1990 following the implosion of the
Meech Lake Accord. After several months as an independent, he became a charter member of the Bloc Québécois party on 20 December 1990. However, Rocheleau's embrace of
Quebec sovereigntism did not play well in his strongly federalist riding, and he was roundly defeated by
Liberal candidate
Marcel Massé in the
1993 federal election, losing almost half of his vote from 1988. He was married twice: to Denise Gagné in 1956 and then later to Hélène Roy. Rocheleau died in Hull at the age of 62. ==Electoral record (partial)==
