It's also not clear what local deference is buying you here, because this is one of the very few cases of a national issue where the right solution is clear and simple and makes sense to implement uniformly at the national level.
The only sense of doing it at a local level is if the national government fails to act.
And local control can still "work" even when the same solution should apply everywhere because they can each individually adopt the same solution, the same as different countries can. In theory a province could even counteract the effect of the federal government trying to get them to spend 10% of the money by just distributing it to the population as it should have been, though of course politicians rarely have that much willpower.
