Canada's Critical Infrastructure (CI)

Critical infrastructure (CI) refers to processes, systems, facilities, technologies, networks, assets and services essential to the health, safety, security or economic well-being of Canadians and the effective functioning of government. CI services operate in a complex web with connections within and across provinces, territories and national borders. For example, hospitals rely on electricity and clean water to function. Disruptions of CI could result in catastrophic loss of life, adverse economic effects and significant harm to public confidence.

The Government of Canada uses a risk-based approach for strengthening the resiliency of Canada's vital assets and systems such as our food supply, electricity grids, transportation, communications and public safety systems.

This includes the National Strategy for Critical Infrastructure, which establishes a collaborative, federal-provincial-territorial and private sector approach built around partnerships, risk management and information sharing and protection.

Enhancing Critical Infrastructure Resilience

Enhancing the resilience of CI can be achieved through a variety of security measures that address malicious and accidental incidents as well as natural disasters. Business continuity practices and emergency management planning are crucial to ensure minimal disruptions and the continuation of essential services.

Critical Infrastructure Partners

Strengthening the resilience of critical infrastructure (CI) requires collaborative work among many partners and stakeholders. Public Safety Canada works closely with other federal departments and agencies, provinces and territories, CI owners and operators, the research and development community and international counterparts to share information, manage risks and reduce CI vulnerabilities across 10 sectors:

Establishing trusted partnerships across the CI sectors is essential for strengthening Canadian CI resilience. By developing these partnerships, we are able to better serve CI owners and operators as well as the Canadian public.

Five Eyes International Partners

Canada works closely with its international partners and allies to enhance the collective security and resilience of CI. Established in 2012, the Critical 5 (C5) is an international forum comprising members from the Five Eyes intelligence sharing network (Australia, Canada, New Zealand, the United Kingdom, and the United States). The Critical 5 aims to strengthen cooperation between member countries by addressing threats to CI, as well as to share information, practices and ideas on domestic policy and operational approaches to CI security and resilience.

In 2014, the Critical 5 published a shared narrative, Forging a Common Understanding for Critical Infrastructure. In the decade following its release, the geopolitical landscape has shifted, and the effects of climate change are being felt more readily. In 2024, the Critical 5 released Adapting to Evolving Threats: A Summary of Critical 5 Approaches to Critical Infrastructure Security and Resilience, which provides an update on the evolving risks facing CI and discusses how Critical 5 nations have been modernizing their approaches to CI protection. It also identifies common means to strengthen the security and resilience of their CI domestically, while recognizing the need for a collaborative and coordinated approach across the international community given the interconnected nature of CI.
