We have information management policies that govern everything we do. We have systems of record that make clear that when you make a decision, you have to document it. Earlier, we heard about encrypted communications. It is required that even if you're using encrypted communications, if you make a decision, it must be documented somewhere else in the system.
I would take the opportunity to mention that it is totally appropriate to use encrypted systems. We use them at PCO because of the national security implications of some of what we do. It's not just Signal; it's BlackBerry Messenger and it's some of our higher-side technology. The classification of the system doesn't change the fact that we have obligations under the Access to Information Act.
We have clear policies in place. We do training with employees. We do training with ministers' offices to make sure people understand what needs to be kept—which types of information—and how long it needs to be kept.
If I'm being completely transparent, if we struggle in one place, it's that we're actually less good at deleting things than we are at keeping them, so we have lots of old financial or HR invoices that, quite frankly, we need to shred, because they're over the age where we need to keep them. That is where we struggle far more than not keeping something that we should. I think the real challenge is the fact that we actually overkeep information in government.
