First of all, I wouldn't necessarily say that they're excluded from the test, but it is true that they're not generally tested.
First of all, when staff are engaged by the Correctional Service of Canada, they go through an enhanced reliability screening to determine whether they have any activity in their background that might prohibit them from working in that environment. As well, on a regular basis, they're obviously supervised by other CSC staff, and their activities are monitored on a regular basis by CSC managers.
The other reality is that when you're dealing with circumstances where you have visitors coming into the institution, for instance, it's a question of volume as well, of creating a bottleneck. If you have tens of individuals coming to visit during visiting hours and you also have the staff.... For staff, it's not just that they come in and then they leave at the end of the day; they take breaks and lunch or whatever the case might be. If we were to try to test every individual coming in and going out, including correctional staff, it would have the potential to create a bottleneck in those services.
