In 1972, the Historic Sites and Monuments Board of Canada (HSMBC) recognized the New Québec Custom House (1856–60) as a site of national historic significance for its historical and architectural values. It gave the same recognition to the Old Québec Custom House (1831–32) in 1990. The Federal Heritage Building Review Office gave classified building status to the New Custom House in 1989 and the Old Custom House in 1990.
The main source of income for the government, the customs office gained in importance in the 19th century and was housed in buildings of impressive and imposing design. The Québec Custom Houses symbolized the power of the government as well as the growth of trade. They were placed within view of the St. Lawrence River, a reminder of their original function as well as the Port of Québec’s role as gateway to the continent, particularly since it was a centre for the lumber trade and the shipbuilding industry around 1850 (event recognized by the HSMBC in 1957).
