History and Heritage

A Strategic Territory

Located upstream from the French colony of Montréal, where the Ottawa River—critical to the extremely prosperous fur trade—meets the strategic military route that was the Cataraqui River (later known as the St. Lawrence), the territory of Vaudreuil-Dorion was a pawn in fierce fighting over control of the Ottawa River, the main economic engine of New France.

After the Great Peace of Montréal was signed with the Iroquois Confederacy in 1701, the seigneury of Vaudreuil-Soulanges—the territory now encompassing Vaudreuil-Dorion, Vaudreuil-sur-le-Lac, Île-Cadieux, Hudson, Saint-Lazare and Île aux Tourtes—was granted to Philippe de Rigaud de Vaudreuil in 1702. At the time, the seigneury had only 90 families of settlers. Then, on April 2, 1763, Louise-Thérèse Fleury de la Gorgendière, wife of Pierre-François de Rigaud de Vaudreuil, sold it to Michel Chartier de Lotbinière, who built a manor there. Development of the seigneury accelerated around 1765, with more and more trading expeditions westward along the Ottawa River. Many fur traders would stop at the manor, and the seigneury took advantage of its strategic location to build a stable farming economy.

The Beginnings of Vaudreuil and Dorion

The parish of Vaudreuil was constituted in 1845, and the citizens elected their first mayor, Hyacinthe F. Charlebois, at their first meeting on July 14, 1845.

In the 1850s, after the opening of the Grand Trunk Railway, the construction of summer cottages began in Dorion. Soon the region was rushing headlong into the modern era. On December 18, 1854, a law was enacted to abolish feudal duties and rights, sounding the death knell for the seigneurial system. In 1891, the territory of Dorion separated from the parish of Vaudreuil and was granted village status. In 1916, it was incorporated as a city. It was named after Sir Antoine-Aimé Dorion, Chief Justice of the Court of Queen’s Bench of Québec, who died the year the municipality was constituted.

The new city of Vaudreuil-Dorion arrived later when Vaudreuil and Dorion merged on March 16, 1994.
