So basically it looks like Metrolinx was right all along to refer to this as limited signal priority:
Transit signal priority will be active on the Crosstown, but its use will be conditional on the vehicles running behind schedule. In such cases, it will be used to extend the green light for the transit vehicle and allow the trains to get back on schedule.
If the City of Toronto is delusional enough to refer to this as Full Transit Signal Priority then I dont know what else to tell them. There's a reason why signal/transit priority has the word "priority" in it. It means that transit would have priority signalling over everything else. But in this half baked case, it's only going to be active if a vehicle is running "behind schedule", and all other times signals will operate as normal. If we cant even get Full Transit Priority on Eglinton, there's basically no hope for the Spadina, Queens Quay, St.Clair, and Queensway ROWs.
And if that's not infuriating enough, here's another thing we can take out of this: the TTC is planning to operate the Crosstown line with a schedule based operation instead headway based. So if you enjoy waiting for your train to leave the outer ends of the line, crawl to the terminal ends, and all the other fun things that come with that well here you go.
