My first comment is that of course you'd have to examine the financial impact of doing that. In other words, you'd only decide that if there's a debt that's owed, you would go back retroactively to six years and no more. And right now there could be cases of deliberate fraud on the part of an individual that would result in an overpayment.
The person, for example, might have knowingly committed that act of fraud. I can give you an example. GIS, for example, is not payable outside of the country for a period of longer than six months. Well, if a person has been living outside the country for more than that and has been collecting guaranteed income supplement payments for a long period of time, is it fair to say that there's not an onus of responsibility to try to recover that overpayment?
While I can appreciate the circumstances that perhaps would lead to going back no more than six years, I think there's a financial impact that would have to be considered.
