Thank you for the question.
I'm going to surprise you, perhaps, by saying that there is one sector that we have not typically considered being part of critical infrastructure but that we need to consider in the future, and that's space. Increasingly, we're going to rely on space-based platforms for critical infrastructure, communications, monitoring of climate change impacts and a whole range of things.
My hope is certainly that in the forthcoming critical infrastructure strategy the government is working on, they will include space as a new sector. I would say that is probably the most vulnerable area, because it is so new and because it is changing and developing so rapidly. There's a Canadian role to play there. Space is a big one.
The other thing I would say is that signals intelligence agencies, CSE and Five Eyes and other ones, have said that what we're facing are probing attacks at the moment by foreign state adversaries who are trying to figure out how our critical infrastructure systems work and where the vulnerabilities are. Will we actually see attacks on those systems, short of war? That's very hard to know. Probably, the answer is that it's not likely because it has such an escalatory impact, but there are certain aspects of it, in particular in terms of democratic practices and election infrastructure, for example, that can be vulnerable.
I would say that space and those critical infrastructure systems that feed our democratic needs around elections in particular are two key issues.
