The Correctional Service of Canada (CSC) defines Security Threat Groups (STGs) as "any formal or informal on-going inmate/offender group, gang, organization or association consisting of three or more members” (Commissioner’s Directive 568-3, 2016). Offenders affiliated with STGs can pose population management and operational security concerns for CSC. Understanding various aspects of the history and characteristics of these offenders assists CSC in its identification, prevention, management, and disengagement strategies. This special report synthesizes high level information based on 16 research publications (two full reports and 14 one-pagers). Infographics are also included. Please note that this report is a one page summary. If you wish to have a copy of the full report, please send a request comment via the Open Government Portal or email the OG team: opengovernmentgen-nhq@csc-scc.gc.ca.
