As you may be aware, the Correctional Service of Canada was recently the subject of an independent review, and there were 109 recommendations that were given to the government with respect to a huge variety of issues for CSC. A couple of the recommendations dealt with the issue of mandatory testing of inmates, which is related to the scenario you are describing. I'm not aware of the specifics of the privacy determination that you're discussing from a few years ago, but I can indicate that it was an issue that was raised in the report that was recently done on the Correctional Service of Canada, and I know it's being looked at.
