In recent years, Quebec has been undergoing a re‐evaluation of immigration and integration policies. The secessionist Parti Québécois had become the leader of this debate, which also coincided with a rise of right‐wing nativist, populist and sometimes authoritarian movements in other Western societies. This paper aims to evaluate the similarity or dissimilarity of Quebec's nationalism to these other nationalisms. We use the 2015 Canadian Election Study data to explore the influence of authoritarianism, nativism and populism directly on support for secession and also, indirectly, on voting intentions. We find that authoritarianism has a negative influence on support for Quebec independence and independentist parties, while the pattern is the opposite, and the effects somewhat weaker, for nativism and populism. Hence, we argue that Quebec nationalism does not seem to correlate with the right‐wing populist movement extending throughout many Western societies. Thus, Quebec nationalism was shown to be a distinct form of nationalism.
