Stormont County area 248,608 acres (1,006 km2) is a county in the Canadian province of Ontario. Stormont was created in 1792, but was settled seven years earlier in 1785. Veterans of Loyalist regiments were among the first settlers. An estimated one third of the pioneers in the county were Highlander, one third German and the rest English, Irish and Lowland Scots people. The original territory of Stormont also included Russell County, which became a separate county in 1800. Stormont later united with Dundas and Glengarry to form the regional government United Counties of Stormont, Dundas and Glengarry.

Wales is a ghost town in the Canadian province of Ontario. It is one of Ontario's Lost Villages, which were permanently flooded by the creation of the St. Lawrence Seaway in 1958. The town was named for the Prince of Wales (later Edward VII) who visited the area during his Canadian tour of 1860. Wales was built on the land grant of Dr. James Stuart, of the King's Royal Regiment of New York. From 1810 to 1957, five generations of the Stuart family lived on this property. Families and businesses in Wales were moved to the new town of Ingleside before the seaway construction commenced. Wales, about two miles away from the old shoreline, was the only inland town affected by the flooding, as the community was located in a creek valley below the new waterline.

Ault Park is a park on the St. Lawrence River in the Township of South Stormont, near Long Sault, Ontario, Canada. Originally on Sheek's Island, the park was built on family property donated to the Township of Cornwall by Levi Addison Ault. Sheek's Island was submerged by the St. Lawrence Seaway project in 1958, and Ault Park was rebuilt on the new river shore.

Moulinette is an underwater ghost town in the Canadian province of Ontario. It is one of Ontario's Lost Villages, which were permanently flooded by the creation of the St. Lawrence Seaway in 1958. Families and businesses in Moulinette were moved to the new town of Long Sault before the seaway construction commenced. The village was located as a strip community along Highway 2, on the St. Lawrence River. At the time of the flooding, Moulinette had a population of around 311 residents. The community would have been located in what is now South Stormont township. Moulinette was settled in the late 1700s by United Empire Loyalists of the King's Royal Regiment from New York. In the nineteenth century many pioneer industries and businesses were established in the village. The origin of the name Moulinette is disputed; it is thought to have originated either from the French term for "little mill" as a reference to the many mills located in the village or from the French word "moulinet", meaning reel or winch as a reference to French ships who navigated the nearby rapids using winches.

Santa Cruz is an underwater ghost town in the Canadian province of Ontario. It is one of Ontario's Lost Villages, which were permanently flooded by the creation of the St. Lawrence Seaway in 1958. Families and businesses in Santa Cruz were moved to the new town of Ingleside before the seaway construction commenced.

Long Sault was a rapid in the St. Lawrence River upstream and west of Cornwall, Ontario. Sault is the archaic spelling of the French word saut, meaning rapids. The Long Sault created a navigation barrier along the river for much of its history, motivating the construction of the Moses-Saunders Power Dam, part of the St. Lawrence Seaway, in the 1950s as the size of ships and the volume of shipping traffic along the river began to exceed the capacity of the area's canal locks. The construction required the flooding of a large swath of land near the rapids to facilitate a hydroelectric dam and to make the rapids area more navigable. The flooded region includes Ontario's Lost Villages. The Long Sault Parkway takes its name from the rapids.
