How do perceptions of demographic change affect the strength of white identity and corresponding attitudes toward immigrants, immigration and personal perceptions of victimhood? While white identity has received scholarly attention in the United States, we know much less about its effects in Canada. We conducted a preregistered survey experiment in which we exposed respondents to different framings on Canada’s increasing ethnic diversity. We find that perceiving demographic change increases feelings of white identity, particularly when framed as an increase in Canada’s visible minority or immigrant population. However, exposure to these trends does not in turn robustly affect respondents’ attitudes toward immigrants, immigration admission preferences or own perceptions of personal victimhood. These findings suggest that white identity is both present and can be primed in Canada; however, it has not yet been politically mobilized in the same way as in other contexts, such as the United States.
