In 1822 a group of Montréal businessmen, perturbed by the effects of the depression which followed the end of the Napoleonic wars, formed a "committee of Trade" with a mandate "to watch over the general interests of the trade of the country". The Committee was incorporated as the Montreal Board of Trade in 1842. During its first century, the Board's role was primarily that of lobbyist, particularly with regard to improving navigation to Montréal and constructing port facilities. They have been closely involved in municipal administrative reform, public health campaigns, anti-pollution and slum-clearance drives. Since the 1920s, the character of the Board has gradually altered to that of an information clearing-house and education facility.
The Montreal Anti-Tuberculosis and General Health League was organized in 1924 to coordinate research into public health conditions in the city, to stimulate public interest in and knowledge of these problems, and to lobby for government action. The League sponsored publications, conducted popular courses, funded the hiring of public health nurses, and made surveys. They operated out of both English and French headquarters. With the establishment of the Board of Health, the League considered its main purposes achieved and disbanded in 1930. Many prominent Montrealers sat on its board of directors, under the chairmanship of Sir Arthur Currie.
In 1850, the Montreal and Lachine Railroad (a nine-mile track around the Lachine Rapids which opened in 1847) merged with the Lake St. Louis and Province Railroad (a track from a point on the St. Lawrence opposite Lachine to the international border, where it was to connect with an American project) under the name Montreal and New York Railroad directed by John Torrance (1786-1870). On September 20, 1852, the rail link between Montreal and the United States was inaugurated (Montreal to Plattsburgh). In 1857, the company amalgamated with the Champlain and Saint Lawrence Railroad under the name Montreal and Champlain Railroad. It continued to operate until 1872 when it was absorbed by the Grand Trunk Railway.
E.L. Montizambert was a resident of Quebec City who worked for the Secretary General Committee in 1845.
