"Prisons see drop in solitary confinement use as vulnerable groups granted immunity."

Vulnerable groups, such as the mentally ill and pregnant women, are NOT granted immunity from solitary confinement.. All that's happened is that Corrections Canada now has a new "policy" in place. It's the same as any employer having a policy in place, but one which it isn't obligated to follow due to law or labor contract. That policy may be there later today, or it may not. The policy may be followed, or it may not. 

The Liberals could have easily included the policy's provisions in its recent legislative changes. The obvious reason why they didn't is because Corrections Canada intends to violate the policy, at least in some cases. So it's virtually assured that the mentally ill, pregnant women and other vulnerable inmates will still be sent to solitary confinement.

I applaud the BC Civil Liberties Association and the John Howard Society for continuing to challenge this inhumane practice.
