In the 1870s, several entrepreneurs from Montreal, including Gustave A. Drolet and Michel Laurent, came together to set up a residential development project of more than 1,000 lots in the village of Saint-Jean-Baptiste by purchasing the farm of Count, east of the land of Cadieux. Indeed, the layout of the blocks, the width of the setbacks and the choice of construction materials and type of housing are the main subjects discussed. That being said, brick duplexes, close together and without setbacks, are emerging on Duluth Avenue. Rapidly populated, this area had 5,000 inhabitants in 1872, the majority of whom were workers and quarrymen, thus undergoing a second phase of development. We then proceed to the opening of new streets, as well as the installation of municipal infrastructure such as the aqueduct, sewers and parks. The east-west arteries of this district, Rachel, Marie-Anne and Duluth, are extended to the east. However, two segments of Duluth Avenue are developing differently. On the west side of Saint-Laurent Boulevard, wealthy Jews took advantage of the horse-drawn tramway to get to the city center and to the east, working-class French Canadians settled in the housing surrounding their work. The village of Saint-Jean-Baptiste acquired the autonomous status of a city in 1884, accelerating its urban development, was annexed and joined the metropolis to the city of Montreal in 1886 which continued its expansion.
