The Lost Villages, Canada
“The Lost Villages” are ten communities in the Canadian province of Ontario, in the former townships of Cornwall and Osnabruck (now South Stormont) near Cornwall, which were permanently submerged by the creation of the St. Lawrence Seaway in 1958.
The flooding was expected and planned for. In the weeks and months leading up to the inundation, families and businesses in the affected communities were moved to the new planned communities of Long Sault and Ingleside. These negotiations were controversial, however, as many residents of the communities felt that market value compensation was insufficient since the Seaway plan had already depressed property values in the region.
The town of Iroquois was also flooded, but was relocated 1.5 kilometres north rather than abandoned. Another community, Morrisburg, was partially submerged as well, but the area to be flooded was moved to higher ground within the same townsite. A portion of the provincial Highway 2 in the area was flooded; the highway was rebuilt along a Canadian National Railway right-of-way in the area.
At 8 a.m. on July 1, 1958, a large cofferdam was demolished, allowing the flooding to begin. Four days later, all of the former townsites were fully underwater. Parts of the New York shoreline were flooded by the project as well, but no communities were lost on the American side of the river.
In some locations, a few remnants of sidewalks and building foundations can still be seen under the water, or even on the shoreline when water levels are sufficiently low. Some high points of land in the flooded area remained above water as islands, and are connected by the Long Sault Parkway. Lock 21 of the former Cornwall Canal (since replaced by the Saint Lawrence Seaway) is a popular scuba diving site, a few feet from the shore along the Parkway.
