Abstract
Until the 1990s social policy played an integrative role in Canada, providing a counter-narrative to claims that federalism and diversity undermine the potential of social policy. Today, however, the Canadian model is under strain, reflecting changes in both the welfare state and the immigration-citizenship-multiculturalism regime. Federalism and the Welfare State in a Multicultural World illustrates that there are clear trends that, if unchecked, may exacerbate rather than overcome important social cleavages.
