“Bodily harm” is to be defined consistently with how the term is used in the Criminal Code.
I spent some time looking at how the courts have interpreted “bodily harm” in the Criminal Code. It certainly reaches not just physical injury, but also psychological injury. However, there is no jurisprudence that I could find—perhaps not surprisingly, given that it was a domestic context—in which “bodily harm” was interpreted to reach a detention or the rendition circumstances that you were describing.
As best as I can tell, no, there is no basis to conclude that bodily harm would necessarily encompass a prohibition on detention, hence our recommendation that detention be emphatically listed.
I would also add that there are forms of cruel, inhuman, and degrading, or CID, treatment that would potentially fall short of bodily harm. Cruel, inhuman, and degrading treatment is understood in international law. However, most of those forms of what's called CID treatment arise in a detention context. Our view is that a prohibition of detention would also then mitigate the risk of any prospect of cruel, inhuman, or degrading treatment and would demarcate, again, a more robust outer limit.
