The critical thing for Ford to do on the transit file was to act quickly because some of Transit City spending had already started - including the LRT vehicle purchase. He did that. Either Ford, or Stintz and the TTC negotiating with Metrolinx, should have considered options for vehicle type early in the process. Instead, they sat on the Memorandum of Understanding for a year and let it get defeated. I don't think Ford wanted an LRT based subway on Eglinton, but he did not get any support from TTC to switch. All Ford wanted was a transit line that does not interfere with traffic. The rest was left up to TTC and Metrolinx to plan.
For Sheppard, I think it would be even harder to find a transit expert who want to extend the Subway to Morningside than to STC.
