Description: The Chambly Canal is a 20 km (12.5 mi.) navigable waterway constructed between 1833 and 1841 that connects Saint-Jean-sur-Richelieu and Chambly. It was originally constructed to bypass the Chambly Rapids on the Richelieu River. The canal consists of nine locks five weirs, two piers, dams, dikes and bridges. The initial construction was by a company led by three Americans and the Andres brothers of Chambly, which went bankrupt in 1834. The subsequent canal, constructed between 1840 and 1843, was designed by William R. Hopkins. It was altered in 1848-60, 1869-1880, and 1880-1895, and restored by Parks Canada for recreational use in 1977-1980 and 1990.

Historic Significance: The Richelieu River was originally known as the River of the Iroquois, who used it as a war route to attack Algonquin tribes residing in the St. Lawrence River Valley. In 1603 Samuel de Champlain ascended the river as far as the rapids of Saint-Ours, and in 1609 he used it to travel to Lake Champlain.

The canal was built as part of the navigable waterway, including Lake Champlain and the Champlain Canal in the United States, to connect Montreal and New York City. From 1835 until the 1960s, it was used to ship various Canadian wood products to the United States, and to bring coal from Pennsylvania to Canada. Since the 1970s it has primarily been used by recreational traffic.

William R. Hopkins was appointed Engineer of the Pennsylvania Canal in 1828, before his work on the Chambly Canal.
