If there's a specific program that is geared towards people in need, and that program needs authorization to use a social insurance number, then there's a process in place for that program to obtain one, either by applying through the existing Treasury Board policy or through legislation from a particular department.
That's the way you'd become an authorized social insurance holder, and that's why we have somewhere in the neighbourhood of 26 authorized users within the federal government.
So if there are specific programs that need to track, as you say, people in need with the social insurance number, that's the way they would obtain it.
