Moving beyond border studies paradigms dominated by the Mexico-US border, this collection aims to contextualise cultures and communities within a wider global understanding of border thinking. It builds on recent considerations of, and changes to, the cultural life of (and across) the Canada-US border, to prioritise theoretical reflections on representations, identities and policies. Approaching the border as a place, a theory, a practice and a process, this collection draws attention to the ways in which aspects of the Canada-US border itself (re)frame discussions of the borderlands as sites that continue to evoke, invoke and provoke ideas of nation and post nationalism; negotiation and imposition; resistance and refusal.
