I will just make two comments.
First, I would say that one thing that makes this topic particularly challenging and that I want to make sure we understand in this room is that we're talking about moving from systems that we call vertically integrated, in which you're dealing with a system such as passports, to a system in which we're thinking about something that combines levels of horizontal systems that enable you to then quickly deliver new services on the top, so that the passport delivery reaches in and grabs information from various horizontally layered services.
The reason I appreciate your question, Mr. Kent, is that I am much more concerned about the governance when you have these horizontal layers, because if you get the governance wrong on something that's vertically integrated, it's very costly—to speak to Professor Clarke's point—but it can be remedied over some medium- or long-term piece, and it doesn't impact all the other things that are going on in government. If we get the governance wrong for one of these horizontal layers, however, it's actually quite serious, because then everybody who builds on top of it is impacted by it.
It's absolutely imperative, then, that this committee think very deeply about the privacy implications, the security implications, the design implications of this approach, because it has knock-on effects for what happens to everybody else.
I think it's very likely that some of these horizontal layers will be held and owned by the private sector. It is unlikely, for example, in the long term, that the Canadian government will build and maintain its own cloud. It will probably have a private sector actor doing that.
One thing that then becomes potentially challenging is that the private player is determining what investments to make, how to expand that infrastructure and what future capabilities it's gong to have. Those choices will constrain what the Government of Canada can do and may even be made in a way that constrains us from choosing competitors when building things further downfield.
We'd better be really sophisticated and nuanced, therefore, in understanding how these players are acting, because they may choose to constrain us in ways that are not immediately apparent to us.
