The COVID-19 pandemic has renewed interest in international supply chains. While international supply chains proved to be very robust in the pandemic period of closed borders, restrictions on movement of people and goods, and closures of businesses, the pandemic proved the need for better tools, particularly for policy makers, to ascertain the health and resilience of international supply chains and the impact they have on their respective economies. This report attempts to provide one such tool with the creation of a set of indices to measure the vulnerability of Canadian industries to disruptions in both upstream and downstream international supply chains.
