For the past decade, debates over the issue of immigration have been a central feature of political life in Quebec. They have underscored the cultural insecurity of Quebecers and the sense that, for many Quebec citizens, immigration is a threat to Quebec culture. These debates have also left the impression that there are regional disparities in the way immigration is perceived. But what is the actual situation? Is cultural insecurity really stronger outside the main urban centers? Are there really significant regional variations in perceptions about immigration, and if so, what accounts for them? This article addresses these questions with the help of a public opinion survey conducted with close to 30 000 Francophone Quebecers during the spring of 2011. Our findings show that there are indeed important regional variations but that, contrary to common assumptions, Francophones living outside major urban centers are not the ones most inclined to perceive immigration as a threat to Quebec culture. In fact, Francophones living in the immediate periphery of the city of Montreal are more likely to view immigration negatively, suggesting a kind of “halo” effect. Our findings also indicate that regional differences are strongest among the younger generations.
