The Sunken Villages Story
July 1, 1958 is remembered as Inundation Day in the Cornwall, Ontario area. At 08:00 a controlled explosion tore open a coffer dam and four days later an area that had once been home to over 6,500 people in 7 villages and 3 hamlets – some dating back to the 1700s – disappeared under the waves of Lake St. Lawrence, part of the newly created St Lawrence Seaway.
A feat of unprecedented industrial accomplishment, the St Lawrence Seaway, was the largest industrial project of its time. It eliminated the massive Long Sault Rapids to generate hydro-power and open the Great Lakes to ocean-going vessels. Completed in only four years it was a source of great national pride. It was officially opened by Queen Elizabeth and Vice-President Nixon in 1959.
In advance of the flooding, residents were expropriated – most willingly – from their homes, farms and businesses, offered new and modern housing in the purpose built towns of Ingleside and Long Sault and largely rebuilt communities of Iroquois and Morrisburg.
