Sure.
Well, with reference in clause 2 of the bill, I can understand why “a promise of confidentiality“ was chosen. That is used in the jurisprudence. But in the 2013 Supreme Court of Canada case called R. v. Named Person B, the Supreme Court said it could also be an implied promise of confidentiality. My worry is that, if you're going ahead with a CSIS privilege, perhaps you should revisit that language, and talk about an explicit promise of anonymity.
My concern is that when CSIS agents go to talk to someone, it's almost always confidential. My concern is that this privilege will apply to virtually every human source that CSIS interacts with. I think it is important for there to be legislative guidance that narrows that privilege, because of the potential downstream effect of the privilege on the prosecution process.
I would also add that it might be wise to require some form of review or ministerial oversight about how this privilege works out if it is enacted. Because, as I said, rightly or wrongly, after four years of deliberation, the Air India commission certainly looked at this proposal, but on balance, rejected it because of concern that this might hinder terrorism prosecutions.
