Again, I think that's something that has to be asked of the department, but there are people who need social insurance numbers for many reasons. For example, if you have a registered education savings program for a child, you need to have a social insurance number for that child. If there is a student who is getting a scholarship, they have to have a social insurance number for tax purposes. If someone is claiming some of the tax benefits, filing tax returns in order to get credits and things, they need a social insurance number.
So there can be a variety of needs. Honestly, we don't have that information.
