From my perspective, the benefit is the reliability of the system. I gave you some really high-profile international examples of what happens when legacy systems aren't updated. In fact, that was the warning that the Auditor General gave the Harper Conservatives in 2010. Nothing was done. I'm glad they care about seniors now, but at that time, clearly there was less care about the regular stability of income payments to seniors. In 2017, the Liberal government at the time decided that we would do something about it, and we began this very difficult process.
Our experience is quite similar to other international experiences, by the way. It's hard to estimate how much it will cost to do this because of the different ways that systems have been shaped and transformed. Don't forget that in OAS's case, it was a 60-year-old system.
The benefit for me is that Canadians who are receiving benefits don't have to think about whether there's going to be a disruption. They don't have to panic when something happens, as in the case of New Jersey, where all of a sudden people weren't getting the benefits they needed in order to pay their rent or buy their food. That's not going to happen with a modernized system.
A modernized system will also reduce the amount of time it takes to process systems, because it's digital. Before, on the old system, everything was hand-entered. There were lots of opportunities for errors. People can type and misplace one letter. It can change a person's name, which can deeply impact their ability to cash their cheque.
These are, overall, the kinds of things that Canadians expect. They expect to be able to trust the systems that are there to serve them.
