CSC institutions have had indigenous elders work within them for a number of years now, and I know CSC institutions also have pathways units that prepare indigenous offenders for that gradual reintegration. Willow Cree Healing Lodge, for instance, receives indigenous offenders from pathways units as well. They're often prepared very well within the pathways units.
So yes, I understand there are CSC institutions that have pathways units, where they're offered an opportunity to engage in indigenous ceremonies and cultural practices under the guidance of traditional indigenous elders.
