The sight of King Charles III receiving salutes and inspecting troops in Ottawa before delivering last month’s Speech from the Throne was more than just a bit of nostalgia. It was a potent reminder of Canada’s history and distinct political culture. In this provocative essay, Jamie Weir argues that Canada, facing a frostier neighbour to the south, should lead a revitalization of links among Commonwealth nations. Canada alongside Australia, New Zealand and the United Kingdom could form a major economic, diplomatic and military bloc: the “CANZUK” nations. United by a long, shared history of freedom and the rule of law under constitutional monarchy, CANZUK could become a beacon of liberty and prosperity in a darkening multipolar world.
