Research demonstrates that English- and French-speaking Canadians differ in a wide range of attitudes, including their political preferences, their vision of the Canadian federation and their national identity. In this article, we ask whether individual bilingualism is associated with a decrease in the attitudinal differences between anglophones and francophones. Using survey data collected in the summer of 2023, we attempt to determine whether knowledge of the French language is related to an increase in the responsiveness of English-speaking citizens toward issues that typically preoccupy French-speaking Canadians. Our analyses suggest that knowledge of French as a second language is strongly linked to the political preferences of Canadian citizens but does not bridge the attitudinal gap between Canada’s two main language groups. These results highlight the relevance of considering the different languages that people speak—and not just their mother tongue—to understand their political attitudes.
