It's a different role because what the intelligence commissioner does to address engaging section 8 of the charter is to review the reasonableness of the minister's decision. It's not oversight of CSE's activities. It's either a quasi-judicial review or I, as the intelligence commissioner, would have come to the same reasonable decision that the minister made, given all the tests that are required, but it does not review CSE's activities. That is the role of NSIRA, to review for reasonableness, proportionality, privacy, and compliance with the law.
