Bingo!
The issue boils down to something quite simple: Metro worked because when it was building out the TTC network, the vast vast majority of growth was within the city and the number of people commuting from what is today the 905 was relatively insignificant.
If your transit system covers the commutershed, you're golden. And we were. And people studied the TTC and Metro.
Now it doesn't, and the transit system is a borderline joke.
In the meantime, Metrolinx probably considers Toronto's needs 10X as much as TTC cares about the needs of a rider who transfers to their system from Mississauga or Thornhill. The limit of their vision is astounding.
You're totally right there's a lot of ways to do it and, as I said, it's not entirely clear something like the MTA could exist here, simply because of the difference in our political systems.
The reason I mention New York (aside from being relatively familiar with it) is that....well, first it doesn't really operate at the same level as the TTC. OK, the geography of our cities is pretty different but quite simply, translating it to our terms, the MTA covers the 416 and 905. Right? It covers Long Island and it covers parts of Connecticut and Westchester County too. Not NJ, but that's like if TTC went up to Richmond Hill (the horror!) and out to Pickering but maybe not Oakville - or whatever. It also covers boats and trains and subways and buses but that's all beside the point; what's relevant is that
one agency is responsible for the vast majority of the commutershed,
regardless of municipal boundaries. For all the concerns here about TTC just disappearing, it could continue to be run as a division of Metrolinx, just like GO. Then maybe YRT is a division and then the Peel systems are amalgamated. The specifics don't matter, just the principles of a single co-coordinating agency with divisions.
The MTA also has dedicated funding and independent authority over all its operations etc. and lots of other things I think we can learn from but I certainly agree the model just can't imported wholesale. I'm sure Translink can't either; we need a GTA-specific solution.
the idea that TTC should keep its fiefdom because Metrolinx is so mean and doesn't understand the city or because the Leaside bus will get cancelled or whatever is crazy. Toronto council has proven, beyond doubt, it interferes too much in transit decisions. It upended citywide plans THREE times in five years, it's repeatedly ignored, postponed, delayed, de-prioritized the line all professional planners consider most crucial to the future of the system and all the mayoral candidates were running insane, unworkable, back-of-a-napkin plans as the backbones of their campaigns. that benefits no one. not TTC, not riders, not taxpayers.
(I mean, I don't want to belabour the point but go on Youtube and watch that
Matlow-Ford exchange on Scarborough again. The idea that this was how transit decisions get made is sickening. it was sickening to watch. They did this for like 2 days AND made the wrong decision. Remember Gary Webster getting fired? Need I go on?)
A properly constituted form of Metrolinx would have significant Toronto presence, at the political and staff level. All these other concerns are just parochialism and insanity to which you've become inured.
