"This Joint United States-Canada Electric Grid Security and Resilience Strategy (Strategy) is a collaborative effort between the Federal Governments of the United States and Canada and is intended to strengthen the security and resilience of the U.S. and Canadian electric grid from all adversarial, technological, and natural hazards and threats. The Strategy addresses the vulnerabilities of the two countries' respective and shared electric grid infrastructure, not only as an energy security concern, but for reasons of national security. This joint Strategy relies on the existing strong bilateral collaboration between the United States and Canada, and reflects a joint commitment to enhance a shared approach to risk management for the electric grid. It also articulates a common vision of the future electric grid that depends on effective and expanded collaboration among those who own, operate, protect, and rely on the electric grid. Because the electric grid is complex, vital to the functioning of modern society, and dependent on other infrastructure for its function, the United States and Canada developed the Strategy under the shared principle that security and resilience require increasingly collaborative efforts and shared approaches to risk management."
