The problem is that the taxpayers in 416 pay to subsidize the TTC through their property taxes. Taxpayers in 905 do not subsidize the TTC through their property taxes. So why should I, as a downtowner who is stuck riding the terrible Queen streetcar, be excited about the subway going to highway 7? If the TTC is going to become regional transit than the entire region should pay. And planning should be a regional thing. A DRL would carry significantly more traffic than the Richmond Hill or VCC from day one yet its barely mentioned.
Obviously, the people who are most excited are the people who will use it - I'm never likely to use the DRL so I wouldn't be "excited" about it, but I can still agree it should be built. I don't know that anyone on these boards is really against the DRL - it's the TTC who seem to be against it, for whatever nutty reason. Part of this is because they're stubborn and part of it is because we're trying to do two things at the same time, I think:
1) Develop a non-existent transit culture in the burbs before gridlock overtakes us
2) Make up for years of neglecting to develop transit in the core.
Neither should take place independent of the other, IMHO, but I feel I've seen many insisting that #2 trumps #1.
I sort-of understand the property tax issue but all it does is hilight how out of date the borders are in terms of both commuting patterns and funding.
Clearly it does not make sense to take the subway up to Steeles just because it's where the taxpayers end. That attitude is part of how we got to the current mess.
Anyway, TTC is not paying for the extension and they will get 100% of the fare box and parking, so that's the simple benefit. If you do what they're doing - take money allocated for a specific project and then ponder whether the you could spend it better elsewhere, you'll find yourself in a neverending series of academic debates.
I presume that when Metrolinx unveils more of their financial plan it will include some sort of regionally-collected transit tax - clearly that's what makes the most sense since allowing each transit system to only think of itself is not in interest of riders.
