Mr. Therrien, thank you for being here with your staff, and for your expertise and testimony.
I'd like to build briefly on the question my colleague, Mr. Picard, asked you in the form of an example to make it concrete for the committee, but also for Canadians who are listening now or are reviewing your testimony in the future.
Could you give us an example of a case from the area of security that would highlight how the application of relevance, necessity, and proportionality would unfold, perhaps an example that both meets and then, in an extrapolation, exceeds the threshold of each of these so there's a better understanding on the part of the Canadian public as to what analysis is actually taking place here?
