There is a very strong framework around security clearances for all workers who come on to the site. That's very robustly managed. There's a very clear system for how people get on site. We feel quite confident in that system.
On the IT systems that you indicated, which are very important, the House of Commons is the technical authority for Parliament—for all of Parliament—on the IT systems. It's actually the House of Commons that takes on that responsibility. For the portion around the Prime Minister's Office, the RCMP has protocols in place for testing and making sure that everything is.... There's quite a strong process around that, in which the House very much takes a leadership role.
Jennifer, I'll go over to you.
