The political importance of race has historically received limited attention across Canadian behavioural scholarship. Building on more recent work, this article comparatively examines the prevalence and effects of white identity and racial attitudes between white Canadians and Americans by leveraging original survey data and a novel conjoint experiment. This article presents several major findings. First, on average, white Canadians express lower levels of racial identity and racial resentment than white Americans, but more similar levels of racial affect. Second, experimental evidence shows that white Americans are more inclined to penalize nonwhite political candidates than Canadians. Third, white identity and racial resentment are strongly correlated with right-wing voting and partisanship in both Canada and the United States, but the magnitude of effects is greater among Americans. Race continues to be of greater political importance in the United States, but it is far from an irrelevant factor in Canada.
