You refer to the example of the incident involving Canada's Communications Security Establishment. I would start by saying that the government claims—and I have no reason to dispute that claim—that metadata, particularly in a foreign intelligence context, is necessary to identify threats. I don't dispute that. The issue with the incident in question was that metadata was then shared with partners, with Five Eyes, in a way that was found by the CSE commissioner, the oversight body, as being unlawful, inconsistent with the statute.
What that tells me is that we have an activity that is legitimate, that pursues a legitimate goal, but is currently regulated in an insufficient way. What I'm looking for—to answer your question—is not a very prescriptive list of conditions necessarily, but currently we have extremely broad provisions that authorize certain institutions to collect and share metadata. I'm looking for some framework, some statutory provisions that would set out certain principles, according to Parliament, according to our elected officials, as to when government institutions would be able to collect metadata, when they would be able to share metadata, under what principles or under what conditions generally speaking, and under what conditions they should retain that information. I'm not looking for something very prescriptive; I'm looking for some basic rules.
