Government Operations committee  I would note three tracks of work. One is the work on outreach that we do through Procurement Assistance Canada. That team in PSPC, for example, last year did 1,700 outreaches, and about half of that number were for equity-seeking suppliers. We have a deliberate focus on the diversity side of our outreach.

Government Operations committee  Lastly—

Government Operations committee  Since I've been joined at the table by Simon Page, I think I will maybe allow him to answer this question.

Government Operations committee  Yes. I think the overall building portfolio is at $2.5 billion, and about $1.1 billion of that is related to the national capital region.

Government Operations committee  Thank you for the question. This is an active area for us right now, obviously, with a very changed set of circumstances. I would note that, prior to the pandemic, we had done some work to identify some significant opportunities to really optimize our office portfolio. There were estimates that 40% of our office portfolio was surplus to our needs at that time, and you can imagine that with hybrid work layered on top of that, we have even more opportunity to shift our portfolio.

Government Operations committee  I'm thinking largely about square metres, basically.

Government Operations committee  It's approximately $1.1 billion.

Government Operations committee  There is no consolidated dataset for doing that, so we rely on a range of different instruments from department to department. The departments have responsibility for the occupancy of the buildings, so we would work with individual departments, whether it's through swipe cards or other mechanisms, to track the attendance or the use of the buildings.

Government Operations committee  Thank you for the question. I would say there's still lots of room for improvement. In fact, we've introduced this with a very open door for feedback from clients and users, and we want to continue to refine it. We want to do a lot more outreach as well. We think there are a lot more than 20,000 vendors out there who ought to be registered, so we're doing active outreach and looking at continued refinement to making the client journey even easier so that they can register with greater ease.

Government Operations committee  Yes, the MHUs are fully outfitted with the supplies and hard infrastructure to be deployed. The minister noted there were some deployments from the mobile health units, including an oxygen concentrator, which was one of the key pieces of equipment deployed in the Northwest Territories.

Government Operations committee  The client department, in this case CBSA, would make the selection, and PSPC would execute that. It would be executed through the existing supply arrangement that PSPC put in place.

Government Operations committee  Yes. I believe CBSA identified a total of 29 contracts, and PSPC was only involved in 21 of them. We can infer that the other eight fell within their own authorities to execute. The others were, as I indicated, a mix: 13 of 21 were competitive, and eight were awarded under these exceptional authorities, drawing upon the pre-qualified list of suppliers.

Government Operations committee  I'm happy to speak to that. The minister mentioned, in her opening remarks, the e-procurement initiative. It has a total budget of about $240 million. Earlier, in the month of September, we went live with the CanadaBuys site, which is the client-facing portal. There are some back-office capabilities, as well.

Government Operations committee  Yes. Twenty thousand vendors have registered on the site.

Government Operations committee  The numbers that the member quoted were correct in terms of the backlog. In terms of overpayments, we have now collected over 80% of the overpayments that have been identified to date and that's an amount over approximately $2.5 billion in overpayments collected. The remaining 20% that you mentioned is the figure that's in the $560-million range of work that is continuing to collect overpayments.
