I find this article confusing. It's about "measures to reduce our economic vulnerability to American antagonism", but I can't see how improving the legal system or adding platform doors to the TTC are related to that. Perhaps the author is confusing economic resilience with economic stimulus?
The author criticizes national-level projects by proposing projects that are entirely handled provincially (or even municipally, specifically in Toronto & Ontario). Yes, this is TVO, which is Ontario-specific, but confusing the responsibilities and capabilities of two different levels of government is not beneficial.
This shouldn't be an either-or situation, but more of let the nation focus on one, and the province on the other. That said, bolstering the judicial system and adding some doors isn't really going to do much for the economy...
