This study applies a strategic framework for assessing organizational and network resilience of 75 critical infrastructure (CI) players in the Greater Montreal area. It identifies the challenges to these CIs' resilience. Contingency analysis is used to describe the main tendencies regarding values, practices, rules and norms, communicational and decisional structures as well as the interdependencies and their institutional, normative and economic contexts. This article examines three well-known CI networks: transportation, energy and telecommunication, comprising governmental, community and private-sector organizations. To do so, we developed a survey instrument to collect data from hundreds of critical infrastructure managers. Our findings indicate discrepancies in internal and external resilience factors across organizational type, size and CI.
