Well, it relates to previous years.
Information has continued to be shared. If you look in the current Canada child benefit calculation, when I said there was a vestigial calculation, the variable that represents that former program, the national child benefit supplement, actually remains in the calculation. It's added and then immediately taken away, so that it doesn't impact the calculation of the Canada child benefit.
It's not operative; it doesn't really do anything anymore. It was left there for an additional two-year span to give provinces enough time to update their programs.
