My colleagues tell me I should try to answer. Of course, it's impossible to know people who are eligible. But if you ask for a figure, what we did was to use a combination of Statistics Canada data, which tell us how many seniors Statistics Canada thinks are in the country, as well as our own administrative data on old age security, as well as tax data. So those are the three sources we used.
If you take all of those things together, you come up with an estimate of about 90,000 people who might be eligible for OAS—old age security—who aren't filing tax returns. We then took that and said that about one-third of OAS recipients are generally getting GIS. Those are the only figures I have. That brings you down to about 30,000 people. We then further reduced that number, because OAS is paid out of Canada, but not GIS, which is only paid if you're residing in Canada. That brings us down to figure somewhere in the range of 10,000 to 25,000 people who might be in that situation--and I underscore the word “might”.
