Old age security and GIS benefits are paid on the same day of the month. They're intended to be received by the client on the fourth-last day of the month. While you could contemplate staggering those with, for example, provincial benefits, we have a number of provinces for whom we do an integrated payment, so that there's only one payment. There are significant administrative savings associated with that kind of a process. I don't have an estimate of the cost that would be generated by trying to pay on different dates.
