Perhaps I can start, and others can add as appropriate.
You're right that ascertaining the impact can be challenging, but I think what this committee has heard is that we understand there is intent by many countries to interfere, and that we really take this seriously and do everything we can to address it.
A lot of the role we play is to understand what those threat vectors look like, so it's about constantly trying to learn. I can speak for the RRM. That's part of what we contribute. We're trying to understand what the threat against Canada looks like, but as you said, there are examples internationally, and the RRM aims to share that information.
Again, it's about a focus on continuously learning what the threat looks like. It's very difficult to ascertain impact, but we know there is intent.
