But as long as Toronto residents alone have to shoulder the cost of maintaining or growing capacity, it will continue to be unfair to prioritize new riders over those already using the system. That's why I believe that the Mayor's comments making the extension conditional on additional funding for capacity growth is both reasonable and prudent.
The Toronto mayor's comments were, of course, purely political, so I don't really know what I think about them. The point is that, yeah, it's got to be done, and doing it helps the whole region. The more we talk about this, the more -- I'm sorry, I know you'll disagree vehemently -- I am beginning to see uploading transit to Metrolinx or something (although its catchment area is enormous) as the only solution. These just aren't productive catfights.
As to who shoulders what load, I genuinely believe that shuttling people from other municipalities into Toronto to participate in Toronto's economy helps Toronto, not just other municipalities, and I have yet to hear a convincing argument as to why it does not. On the other hand, I further believe that it is not the kind of argument where you can do an accounting and come up with a definitive answer. There are too many devils in those details and a creative accounting could tell just about any story one likes. So, again, I'm beginning to think that having a huge central transit agency that, nonetheless, is only as huge as the City of Toronto, doesn't work too well, because you end up with thsee unproductive bunfights. Either get more local, or get regional. The TTC is neither.
