I certainly have some comments on the subject.
It obviously ties in with what the Honourable Nicola Di Iorio said about best practices in this regard.
We must always bear in mind that although we can draw inspiration from these practices, there's not necessarily a Charter of Rights and Freedoms in other countries, even some very developed ones. So we must be careful when importing what we consider to be other countries' best practices. It poses a problem.
We saw with Mr. Arar, and with everything the commissions showed, that information can be obtained under torture. Such practices are prohibited in Canada. However, the information can be shared and used by CSIS against people. Moreover, with Bill C-51, a chain can be established. It can justify an arrest, because it's believed the person could commit a terrorist act. Charges can be based on information of dubious origin, using secret procedures.
In short, this is what happens.
If the threshold for the consequences is reduced, that means whatever information you get under torture or under conditions that aren't acceptable in Canada can lead to consequences that are much more grave for the person involved.
That, I think, is where the problem is. If information has been obtained through torture, we must be careful not to make the consequences even more grave. That's what Bill C-51 does.
Furthermore, Bill C-51 allows all agencies and all governments to transmit the information as well, even though we don't exactly know where the information is from. That's even more problematic.
