The Jewish community on the Main sprang up after the heavy immigration of the early to mid-1900s. Jewish settlement occurred first on the lower Main, in a section that now is part of Montreal's Chinatown.By 1871 a Jewish enclave numbering just over 400 people had formed by the corner of St. Lawrence and Dorchester Street, with the first Jewish educational institution, the Talmud Torah, located at the corner of Saint Urbain Street and De la Gauchetière Street. Middle-class members of the community were already beginning to move up the Main towards Sherbrooke and Prince Arthur Streets, while further west, a small number of well-off Jews lived near McGill University.
