I'm not an expert on cybersecurity. I notice that the Supreme Court is not part of Shared Services Canada and that seems to me an indication of the reasons they would not want to be part of this aspect.
Another aspect that I didn't mention on this issue is the problem of confidentiality. Everybody who is employed by Statistics Canada, be it ever so short, has to swear an oath of confidentiality; it even applies to casual employees. Under Shared Services Canada, other people are handling information and making decisions, and there is no oath that requires them to have this type of confidentiality. I would suggest there's an increased danger rather than anything else.
