He was one of the founding members of the
Parti Québécois in 1968. He ran for the
National Assembly of Quebec in
1973 in the constituency of
Charlevoix, but lost. He was elected in the constituency of
Lévis in
1976 and was re-elected in
1981,
1985,
1989 and
1994. Under
René Lévesque, he was Agriculture Minister. His most notable accomplishment as Cabinet Member is the passage of a law on
agricultural zoning in 1978. After Lévesque resigned as party leader in 1985, Garon ran for the
Parti Québécois leadership in 1985 but finished third with 16% of the vote, defeated by
Pierre-Marc Johnson (59%). As a Member of the Official Opposition, Garon vice-chaired, then chaired a number of parliamentary committees, including the one on Economy and Labor. The Parti Québécois won the 1994 election and
Premier Jacques Parizeau appointed Garon as
Education Minister. The resignation of Parizeau as Premier corresponds to a decline of Garon's influence in provincial politics. Garon, who belonged to the
more radical wing of the PQ, was considered a close ally of Parizeau. Premier
Lucien Bouchard, who succeeded Parizeau and is widely viewed as a moderate concerning constitutional issues, did not appoint Garon to his Cabinet. Nonetheless, Garon chaired the Parliamentary Committee on Culture. In 2013, Garon said he is convinced that like René Lévesque, Pierre Karl Péladeau will be able to rally the necessary sovereigntist forces to make Québec a country. Garon was one of 12 sovereigntist personalities who signed a letter of support for the candidacy for the businessman for the riding of Saint-Jérôme. He confessed to having doubts that Pauline Marois would be the one who would succeed in unifying the partisans of an independent Québec. According to him, this unity is an essential condition to obtain a majority support from Québécois to the
Oui side during a referendum. ==City politics==
