Environmental Scan 2013 provides an overview of the key drivers and trends defining the context in which the Canadian Safety and Security Program (CSSP) is anticipated to operate over the next three to five years. The scan's objective is to present a comprehensive and integrated picture of the public safety and security operating environment for the purpose of informing the development of CSSP priorities. After briefly outlining the broader safety and security and science and technology policy environments, the scan examines nine issues, threats, and hazards that constitute the problem space for CSSP activities.
