We are talking about supporting a vision here, not strictly about what's in play or implementable. Obviously that's going to be Transit City.
However, this is an important discussion to have. There is a strong possibility that a change in policy or direction with a new mayor could make Sheppard an orphan line....at least in Scarborough. That's why, it's extremely important to discuss our vision for transit at this stage before any shovels really hit the ground. There has to be transit vision that'll survive more than one administration. If that's not there, Scarborough will get another orphan line or two (if the next guy settles on ART Mk II for the SRT re-build). If that came to pass, it would be a disaster for Scarborough, nearly on par with the current SRT.
IMHO, there should have been a compromise plan. Some subway, some LRT. Unfortunately that didn't happen with TC, which in turn forced our hand. I honestly believe, that the planners of Transit City intentionally misled the public and the province. How else to explain costs ballooning from $6 billion to $15 billion before the first shovel is in the ground (water main movement and grade separation on Sheppard don't count...they had to be done). Had they said right from the start that they were going to spend $15 billion, people would be asking, why it was all going to suburban LRTs and why they weren't spending on at least partial subway extensions. They picked the routes, lowballed the estimates, and once it got rolling, started jacking up the prices.
Now we get new threats. If you don't build this, you won't get anything. Really? I don't buy it. Is anybody really saying, for example, no DRL if we don't build Sheppard? I want somebody to tell me how much the Sheppard LRT will help in the grand scheme of things. Nobody will diverting from any parallel avenues. It will still require some parallel bus services (ie. the 190). Yet, this is the most important priority for transit in Toronto, the sacred cow that can't be slaughtered? Are people so desperate to build something, anything, that they are willing to re-order their priorities to spend a billion dollars on not even the most highly trafficked or most urban avenue in Scarborough?
I don't buy the threats and fearmongering. We live in an era of Metrolinx. And transit has become important to every party in the political spectrum. The gridlock that will ensue if transit isn't fixed will be a threat to any elected government. That alone will ensure that whoever is in power will have to fund and build transit. The fact that Metrolinx is in control, also gives the higher levels of government peace of mind. It's no longer a mayor playing with his train set. And as long they feel they have control and some say, they'll be far more inclined to fund whatever we ask for (providing it's in line with their vision).
On the specific question here...I don't think TC was entirely a Steve Munro production. Steve is undoubtedly one of Transit City's biggest fans and proponents. But the mayor and his protege have more than their fair share of blame. I am willing to bet that the plan to cook the numbers and fool the province was entirely a Miller-Giambrone production. Ditto for the decision to ensure that subway construction in suburban Toronto would be all but be killed off by prioritizing potential subway routes for LRT construction. They played McGuinty and Metrolinx well. I'll give them that. Who else could have sold LRTs as a critical piece of a regional transit plan ensuring people can travel across the region? And who else could fearmonger like Miller? This is the supposedly transit friendly mayor, who when faced with a budget shortfall, threatens to close a subway line. With threats like that, no wonder people think it's Transit City or nothing.
