I think there are two issues here. One is around certification that the work has been done. The other one is around whether the costs have been allocated correctly to the cost centre.
For example, a cost centre manager may well have been observing and seeing that the individual on the invoice had done 30 hours. However, they may not have been allocated to specifically ArriveCAN. This is what I said at the start of this evidence: We did a mistake in not setting up a separate ArriveCAN cost centre code from year one. When we were receiving an invoice, we would say, yes, those 30 hours have been done, but we weren't coding it between ArriveCAN or operational expenditures or elsewhere.
However, we are now looking at all of these invoices, because a number of allegations have been made, to go back and make sure that we have not been overcharged. If we do find that we have been overcharged, we will pursue repayment for those. The minister for the Treasury Board announced last week that PSPC had identified some overpayments. We will be doing the same. If we identify any invoices that were not for work done, we will be pursuing payments for that.
