That's a very good question, and it's a tough question because the danger of oversight is that if you approve something in generalities, you might feel committed to something that happens, even if it was unanticipated.
I tend to think of these things more in terms of review and that where the oversight comes in our parliamentary system is with the minister. Reports to the minister are a lot of what SIRC and the CSE commissioner do. I'm aware that we don't see most of those reports. That's something that the new National Security and Intelligence Committee of Parliamentarians has to do, basically to call to account the minister if he or she fails to oversee what is going on.
Again, Professor Carvin raised the issue that the Department of Public Safety is a gargantuan ministry, and perhaps sometime in the future we need to look at splitting that up to take things such as corrections out of it and to have a more narrowly focused security ministry where the minister has a fair chance of keeping on top of everything that he or she is ultimately responsible for.
