He continued to sit in the House as a private member throughout the then-existing Parliament. At the general election of 1854 he was again returned for the city of Montreal. During the ensuing sessions, though he did not accept office, he was a very serviceable member of committees. In 1856 he was Chairman of the Committee on Public Accounts, and introduced some important improvements in the method of tabulating items. At the general election of 1858 he declined re-nomination, as his health was far from good, and he was desirous of repose from public life. In 1863 he was an unsuccessful candidate for Montreal West, his successful opponent being the late Hon. Thomas D'Arcy McGee. Nine years elapsed before he again offered himself as a candidate for Parliamentary honours. In 1872 he once more came out for Montreal West, when he was returned by a majority of more than 800. Two years later he bade a final adieu to political life, in order to give his undivided attention to various commercial and industrial enterprises with which he was connected. He continued, however, to take a keen interest in public affairs, and to do his utmost to promote the interior trade of Canada and the carrying trade of the lakes and St. Lawrence. He never ceased to advocate the establishment of reciprocity between Canada and the United States. In 1875 he was Chairman of a commission appointed to consider the bearing a Baie Verte canal would have on the interests of Canadian commerce; and after a very exhaustive inquiry he prepared a report unfavourable to the project. In addition to the projects already mentioned in the course of this sketch as having been actively promoted by Mr. Young, he did much to enhance the due representation of Canada at the various International Exhibitions, and the last public appointment filled by him was that of Canadian Commissioner to the International Exhibition at Sydney, Australia, in 1877. He also took an active interest in ocean telegraphy, and in the improvement of the harbours of Canada. After his retirement from Parliament he filled the office of Flour Inspector of the Port of Montreal on behalf of the Government. He continued to identify himself with every local measure of public importance down to the time of his death, which took place at his home in Montreal, on Friday, the 12th of April, 1878. The funeral, which was attended by a great concourse of influential citizens, was on the 15th. The local press did due honour to his memory, and bore unanimous testimony to the fact that Canada, and more especially the city of Montreal, had sustained a grievous loss by his death.
