Structured Intervention Units

Structured Intervention Units - Understanding our federal correctional system

 

Correctional Service Canada (CSC) is responsible for keeping Canadians safe and assisting in rehabilitating offenders so most can eventually return to the community and be contributing, productive members of society.

The health and safety of our employees and those in our care and custody is our top priority. CSC transfers offenders to Structured Intervention Units (SIUs) only when they cannot be safely managed in the mainstream federal prison population because of risks to their own safety or the risk they pose to others.

In 2019, CSC abolished administrative segregation. Since then, SIUs have been implemented at 14 correctional institutions across the country. They help offenders adopt more positive behaviours through targeted interventions and programs.
