I presume it's only because this is affecting students way at the City's edge that this isn't a big news story every day.
(i.e. if people trying to get to U of T and Queen's Park were being forced to get off at Dundas and walk, it would be.)
It's an utter failure of policy and everyone at York U, TTC, Metrolinx and YRT should be roasted for it. They had a decade, supplemented by a two-year construction delay, to work out something to avoid this precise issue which everyone could see coming a mile away. It's embarrassing, not just because of the specifics but because of what it says about the total inability of our transit agencies to function coherently for the riders they serve at a systemic level. People who live just north of Steeles have longed complained about the fare wall and you can see people parking their bikes and cars at Steeles to avoid paying it. You could stand at Yonge/Steeles and watch half-empty YRT buses live "TTC riders" standing at the stop waiting for a packed bus that's actually allowed to pick them up.
And now we've institutionalized and formalized this counter-productive, outdated system. It doesn't bode well for RER/SmartTrack, which is useless without integration, and while I don't think Doug Ford's uploading plan could possibly be done sensibly, at least someone is attempting to grab the bull by the horns. No one else seems to much care; and in an election year, no less. In the meantime, every day, 1,000s of riders suffer because of it.
That's my two cents, anyway.
