The Cornwall Canal was one of eight canals that connected western Canada with the ocean by way of the Great Lakes and the St. Lawrence River. Constructed in 1834 - 1842 to overcome the rapids of the Long Sault, it was enlarged several times between 1876 - 1904 and superseded by the St. Lawrence Seaway in 1959.
