People along the western waterfront would disagree with you. The Waterfront West LRT (I'm talking west of Ontario Place) is nowhere in sight, and no alternatives are anywhere close, despite some of of the biggest growth in the city. This was a big part of Transit City.
Along those lines, I've long been an advocate of adding GO stations at the Humber Loop and Roncesvalles, but it's always seemed that Metrolinx's aversion to "competing" with the TTC is why this hasn't happened.
Now that Metrolinx wants to be the overlord of all public transit, coupled with opportunities from electrification, I'm hopeful.
