Cornwall Canal

The Cornwall Canal was built by the British government of Canada to bypass a troublesome rapids hindering navigation on the St. Lawrence at Cornwall, Ontario.

[1][2][3] The canal extended past the Long Sault rapids from Cornwall, Ontario, to Dickinson's Landing.

[4] It closed in 1968, after becoming obsolete and functionally replaced by the St. Lawrence Seaway and its Wiley-Dondero Canal on the US side of the river.

Most was subsequently filled in, helping to create Lamoureux Park.

A section still remains as a long body of water stretching to the foot of the Moses Saunders hydro dam revetment.
