A case study of the decision-making and outcomes of Canada’s border management in response to COVID-19 is one thematic focus of our research. Canada is a highly globalized country with a diverse and mobile population and an economy dependent on international trade and investment. During the COVID-19 pandemic the federal government deployed a wide range of travel measures to manage public health risks associated with high volumes of cross-border travel in Canada by land, air and sea, including the world's longest international border with the United States.
