It's because of our parentage, in the sense that we were both born from the same organization. In the early 1990s—this will be short—we, Customs and Tax, were integrated. We spent an awful lot of time over a decade integrating our IT systems. Early in the decade, in 2003, after the terrorist attack, the decision was made that we would move Customs over to become part of Public Safety.
As I said earlier, it was somewhat easy to divide up people, but the infrastructure was extremely difficult to divide up. We had discussions with Treasury Board. We talked about what the cost might be to duplicate the system. It was a massive amount--over hundreds of millions of dollars--to break up and create a new system. It was decided at that point in time to have us provide that service for the border agency.
It's been a very successful experiment, to be honest. Originally, there may have been a few irritants, and the border agency may have felt like the boarder upstairs in the house, but I think now it feels it's an equal partner. We have a new governance regime in place. We've just signed some new MOUs with it in place. The agency's demand on our IT system has grown significantly in recent years as it has become much more automated. So at this stage we're almost 50-50 in terms of usage.
