It's been very onerous; I think all of us have found that. It's a very much increased level of support that you need in order to provide for parents and grandparents than that, for instance, needed to support other family members. It's the low-income cutoff plus 30%. The fact that people have to show that income in one specific way—as you say, just from their CRA notices of assessment, basically—and that it has to be for three years automatically means that there's going to be a delay in that family's reunification, because the person will have to wait at least three years in order to show that proof and be able to start sponsoring their parent or grandparent. That process is now taking about two years, so there are six years of non-family reunification.
