I think the main crux of the issue—this always surprises people when I say it—is the fact that the Canada social transfer gets put into general revenue. It could be used for potholes. We don't know, so the first step is knowing how it's used. Then we can get to outcomes.
I will say that on the outcomes side, there's some really interesting work being done around social return on investment, but a lot of it comes down to addressing poverty and fundamentally addressing social determinants of health.
