There may be a variety of reasons why these people were not eligible. They may not have had the necessary years of residence, or their income situation may have changed. So over and above the fact that they might not have known they had to apply, there might have been reasons in their instance for why they may not have been eligible for the benefit. There are also many cases of eligible seniors who have declined the benefit, for a variety of reasons, and don't ever want to apply. And there are lags in time in terms of when the department obtains tax data, mails an application, receives it back and determines eligibility.
So there are a variety of reasons why you may have a certain number of people who are not obtaining the benefit at any one point in time. I don't know the numbers, because I don't recall the figures that were in that report.
