That's a very good question. We could discuss it at length, but I will limit my comments on the matter.
There is certainly a question of culture. Canada has seen a deinstitutionalization of people with mental health issues in the last 30 or 40 years. Unfortunately, this has led to a trend toward over-incarceration. Some people with mental health issues are ending up in the criminal justice system more often.
So the Correctional Service of Canada inherited this problem. As Mr. Sapers explained, the CSC acknowledges it. Some cases have made headlines. More and more, correctional officers are being offered training to recognize the signs and symptoms of an inmate with mental health issues so that they better adapt their approach. However, this isn't something that happens overnight.
First of all, prison is part of a correctional system. People can't expect prisons to play the role of psychiatric hospitals. There is always tension between these two realities.
