Let me try to make this a concise response.
As you know, Canada is a party to the seven core human rights treaties. Time doesn't allow me to run through them all, but certainly the convention against torture obviously is right up there and, as Ambassador Rishchynski said, we've got a very clear commitment when it comes to where we stand in seeing that torture is not present.
When it comes to the optional protocol, I think the one that you're referring to has to do with oversight of detention facilities, and at this stage we don't have any plans to join that optional protocol. We believe that obviously there's a great deal of importance that should be placed on independent oversight of the conditions in places of detention, but Canada has robust mechanisms to do that and so that would be my response to your question.
