Mr. Villeneuve was frequently called to public office and it is a notable fact in his career that no public trust reposed in him was ever betrayed in the slightest degree. For more than seventeen years he was mayor of St. Jean Baptiste village and again, when the organization of the town took place, he served for four years more, carefully guiding the interests of village and town so as to bring about needed reforms and improvements. Following the annexation to the city in 1885 he represented St. Jean Baptiste ward from that date until 1894 in the city council and as a member of the finance committee his experience in financial matters was found to be of great service to the public. Higher official honors awaited him, however, for in 1894 he was elected Montreal’s mayor and filled that position for two years, proving a capable executive and one who most carefully and systematically safeguarded the public interests. For eighteen years he served as warden of the county of Hochelaga and in 1886 was elected to represent that county in the Quebec legislature, where his record was so commendable that he was reelected in 1890 and again in 1892. In 1888 he was made a member of the harbor commission and served for several years on that body. In January, 1896, he succeeded the late Hon. Joseph Tasse as senator for the De Salaberry division. All this, however, did not cover the many phases of his activity. For many years he was a member of the Board of Trade, and he had important business connections, serving as director of the Dominion Cotton Company, in addition to which he had other large manufacturing, mercantile and real-estate interests in the city. He was resident director of the Banque Nationale and a member of the harbor board and a governor of Laval University. He was also senior partner of the firm of L. Villeneuve & Company, wholesale lumber dealers.
