What was the state of the transit plan that Miller supposedly threw in the trash?
It was evaluated, with certain projects prioritized. It was also already officially adopted into the City's OP.
Did it have funding in place (even if for only part of the plan)? Did it have completed detailed plans and designs? Did it have contracts signed? Did it have construction starting or about to start?
For Spadina, yes it did (except for the Feds, which delayed funding for a few years, but that's not the City's fault.
It seems silly to try and make them seem equivalent..
The better question to ask would be: if Miller had stuck with the RTES, would he have gotten the same degree of funding commitment that he did with TC? I think he probably would have. When he would have gone to the province for funding, he would have had completely planned, partially engineered projects that could have been shovel ready in a couple years (and this was in 2007). In addition to Spadina, we could have had at least one other subway construction project signficantly underway by now, possibly two. So I think it's somewhat hypocritical to praise 1 mayor for throwing a transit plan in the garbage, but condemn another for doing the exact same thing. Do I think what either of them is right for doing it? No. If you're going to change a transit plan, make incremental changes, as opposed to wiping the slate clean*. At least that way work from the previous plan can be either carried over completely, or adapted for use in the new plan. Had Miller done this, we would be at least two years further ahead than where we are now, possibly even more than that.
*Note: The one exception to this I can think of is the 1st Ottawa LRT plan. That thing was beyond fundamentally flawed, and it wasn't worth the paper it was printed on. In rare cases like that, throwing the thing onto the fire and watching it burn is acceptable. Although to be fair, I'm glad they didn't literally do this, because the section from Bayview to Riverside South in the new plan is identical to the 1st plan, so it's pretty much shovel-ready right now, just waiting for funding.
