Mercier (French pronunciation: [mɛʁsje] ⓘ) denotes the eastern portion of the Mercier–Hochelaga-Maisonneuve borough of the city of Montreal, Quebec.This social transformation was induced by the arrival of large industries in Longue-Pointe and the building of a tramway on Notre-Dame Street.The extension of the metro and elimination of the tramway exacerbated industrial activity, and the remnants of the rural landscape of Longue-Pointe disappeared.[1] Unlike neighbouring Hochelaga-Maisonneuve, it suffered a lesser degree of economic decline and poverty related to the movement of capital and production to Toronto.Other notable features include the Place Versailles shopping mall, the Institut universitaire en santé mentale de Montréal, the Sanctuaire Marie-Reine-des-Coeurs and the historic Chateau Dufresne.
