This article introduces White identity as an understudied concept in Canadian politics and compares how White settlers’ ingroup attachments and their outgroup attitudes—specifically, White settlers’ anti-Indigenous attitudes—shape Canadian politics. We find that White identity is associated with greater support for government spending on policies that disproportionately benefit White Canadians, such as pensions, whereas Indigenous resentment is associated with greater opposition toward government spending on policies that are often perceived as disproportionately benefiting Indigenous peoples, such as welfare. In Canada outside Quebec, both White identity and anti-Indigenous attitudes are associated with voting Conservative. In Quebec, White identity mobilizes support for the Bloc Québécois, while White settlers’ negative attitudes toward Indigenous peoples are not associated with vote choice.
