Structured Intervention Units (SIUs) were launched on November 30, 2019, bringing transformational and historic changes to federal corrections. Administrative and disciplinary segregation were eliminated and no longer exist in federal correctional institutions in Canada.

SIUs are operating at 15 sites across the country.


A transformative federal correctional model that adopts a positive, intervention-based approach to address individual inmate needs for the safety and security of the institution.
