Mr. Chair, thank you very much.
I thank both of our witnesses for being with us this afternoon.
This is an extremely complex area, as you and our previous witnesses have outlined. It's highly interdisciplinary. We're talking about the establishment of an ecosystem that, in many parts, has not been established yet, or has been insufficiently established. Then we have the Russia-Ukraine invasion, which has brought everything to a point and illustrates the urgency with which we need to look at this issue.
This goes into the private sector, into public civilian infrastructure, and into the military side. We saw, through the response of the European Union, Canada and many of our allies with respect to the application of sanctions, how quickly the private sector and the capital markets are implicated in a security question.
I'd like each of you to take a moment and give us a thumbnail sketch of the state of this ecosystem at the moment, looking at these complexities and interdisciplinarities. What needs to be done urgently, from the perspective of the federal government? What are some of the challenges, operationally, with respect to human resources, changing our mindset, and looking at digital security as an urgently needed and, ideally, rapidly growing area of investment?
If you could zoom back to your initial comments with a bit more depth for 45 seconds each.... I have limited time, and that would be helpful.
