In fact, there was. I know I myself was actually involved in a refusal to work situation before Bill C-83, because there were subpopulations being created with, as I iterated earlier, what would normally have been classified as segregated inmates, mostly inmates who would have been segregated for protective custody reasons.
There were areas of the institution, specific ranges, that were associated with different movement routines, so they couldn't associate with the general population.
The CSC was, in fact, then housing inmates in the least restrictive manner.
