The development of the Lachine sector is fundamentally tied to the Lachine Rapids, a stretch of water that prevented ships from travelling from Montreal to the Great Lakes. In the 17th century, when Lachine was a fur trading post and refuge, two roads were built: Lower Lachine Road, the first portage road that linked Lachine to Ville-Marie, and Upper Lachine Road (present-day Saint-Joseph Boulevard), which served as the main thoroughfare toward the west. To bypass the rapids, Dollier de Casson, Sulpician superior and seigneur of the Island of Montreal, initiated the first canal project in North America, in 1689. This project was never completed, but a few vestiges remain on the present territory of East Lachine.
The Lachine Canal was built in 1821, inaugurated in 1824, and expanded in 1843-1848. It facilitated the transportation of goods and provided the hydroelectricity needed to power industrial production. In 1847, railway services were introduced to Lachine. With this, the territory along the canal became the Canadian leader in industrial activity between 1873 and 1885.
At the end of the 19th century, several companies set up in the East Lachine sector: Dominion Bridge, which made a name for itself in bridge and metal structure construction, opened its doors north of Saint-Joseph Boulevard in 1885; Dominion Wire and Dominion Wire Rope and Cable arrived shortly thereafter. In the early 20th century, the equipment manufacturers Allis-Chalmers and Jenkins Brother completed the industrial landscape of East Lachine.
