Moulinette, Ontario 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.
The land which Moulinette occupied was originally given as a land grant to a Sir John Johnson around 1784, however the land ended up in the possession of one of his relatives, Adam Dixson (sometimes recorded as Dixon) who settled the land here. Upon his arrival, Dixson constructed a dam, which ran from the nearby Sheek’s Island to the mainland, in order to generate power; immediately following this, he established a grist mill. The village of Moulinette grew surrounding this mill and dam, and Dixson is credited as its founder.
The community had its own post office by the 1830s, and by 1840, the village boasted 100 residents. Two churches had been constructed to serve the community, and many pioneer businesses had been established. During this period, the village had a sawmill, a foundry, a carding machine, a general store and a tavern. Additionally, a brewery operated around this time, however three years after its construction in 1840, it burned and was not rebuilt. The town also had two woollen mills, located on the nearby island.
By the end of the nineteenth century, the construction of the Cornwall Canal allowed Moulinette to prosper as a village. The flooding of the canal had submerged part of the village and the nearby Sheek’s Island; the woollen mills were lost to the flood. During this time, a flour mill and another saw mill were built to replace the lost mills. The village was now home to two hotels, called the Lion and the Pea Green; as well as two general stores, two wharves, a cheese factory, barber shop and an elementary school.
