If you're referring to the main estimates, then the programs that were receiving supplementary estimates today would have had a zero or a dash, because they would not have been appropriated yet. For the aboriginal justice strategy, supporting families, and immigration and refugee legal aid, they would have shown a dash in main estimates, because there would have been no funding appropriated. And they're being appropriated today, if you agree.
That would explain how you would have seen zeros for some programs.
