My interpretation of the Vavilov decision on reasonableness is the following.
Decisions have to be sound, factual and based on the facts of the case. Decisions also must take into consideration the privacy of Canadians—our privacy. I insist on that and I get involved. Deference for me has a limit. If I see that something is wrong, as I did in one decision.... I refused completely what CSIS was asking. They came back a few months after they reviewed the situation, and they presented a completely other file and I agreed with it.
In essence, to be clear—your question is valuable—what I'm saying is that in law, reasonableness in the way we're applying it takes into consideration deference, but not to the limit of being a servant of the decision-maker.
