Following the Quebec referendum on sovereignty-association in 1995, many political observers assumed that immigrant voters would support the federalist option, and that only a minority among them would vote for the Parti Québécois option. However, in view of the considerable changes in the linguistic integration of immigrants over the last 20 years, their electoral behaviour might vary. Focusing on a survey in Spring 1996, the authors confirm the existence of a greater pluralism among immigrant voters. Moreover, the data emphasize factors in favour of a social vote among those citizens, especially in the Montreal region. Diversification of electoral choice is supported by the percentage of those who learned French and who identified themselves as Quebeckers.
