Ill go one better. I think this is proof the transit system needs to be uploaded to the province and the TTC disbanded. They've proven they are unable to do their job.
The TTC is problem-plagued, there's no arguing the point, I wouildn't dream of it.
That said, Metrolinx are no better. Sure GO Trains are broadly more reliable, but off-peak service, where it exists, is mostly hourly outside of Lakeshore, and then only 30 minutes.
Mx contracts most operations and maintenance to third parties, meaning the bulk of its management team have limited knowledge in how to build or operate things.
Mx has also been the home of countless capital project boondoggles, including this one.
Meanwhile, if you did 'abolish' the TTC, the reality on the ground is that it would just be a name change and a new top boss.
The organization is 17,000 people, with far more subject matter experts and vast amounts of work done in house. Some of it, not as well as it ought to be; but then again, the TTC has moved to bring vehicle cleaning back in house
as the private sector was no great shakes at that either.
The TTC (and Mx) need substantial reforms. But I wouldn't get tied up with a giant re-org/re-naming that will really leave all same problems, just an even bigger bureaucratic morass.
Functionally any Mx takeover of the TTC would simply be a reverse-take over, where the TTC swamps Mx.
You'd just be paying to move Mx Staff into Davisville or find the combined office a new HQ as Union certainly would not serve purpose.
