According to the MOU between Ford and McGuinty, the line could be elevated near the Don Valley - which is a 4 km long stretch. The problem is that they actually spent no time trying to design the connected ECLRT/SRT. They just looked at ways of sabotaging Ford.
For the Leslie stop, it was Metrolinx who said that the portal in its current location was not possible. Again, it was their politicking that led to the wrong things being explored.
The choice was for Council or the Provincial Liberals to explore ways of improving transit. It's not my fault that the politics turned to "defeat Ford at all costs", instead of "how can we work with the most pro-subway Mayor in Toronto history to build more rapid transit". Ford, and then Tory, actually secured additional money, but it was the planning that went horribly awry and prevented the right things from being done.
