Not sure why you are ignoring that he pushed the Spadina extension and the DRL, with a lot of pressure from city coucil to accelerate the DRL in the Regional Tranportation Plan (Big Move) where it was initially proposed to be in the 25-year plan rather than the 15-year plan. By the time Miller left it was in the 15-year plan on, on everyone's radar, and in the city's plans.
He PUSHED the Spadina Extension? No one wants to turn this into a Miller-bashing thread - as I said, I basically like the guy - but that's revisionist nonsense. The Spadina extension pushed HIM.
The DRL got moved up in The Big Move? Yes, after the fact.
After which fact?
After the fact of him realizing that the Yonge extension was getting pushed on him, just as the Spadina extension had been. I'll give you dollars to donuts that IF Miller had run and been elected for a third term and IF the Yonge extension hadn't been pushed by York Region and the province, that the DRL would still be in the 25-year section of The Big Move. He was anything but pro-active there and, really, his anti-subway rhetoric is occasionally as galling as Ford's anti-LRT rhetoric.
To listen to the Toronto Urbanist Crowd, you'd think DRL has been their priority forever. No one in the city had ever heard of the darned thing - aside from the nerds who hang out on boards like this one - until the Yonge Extension EA put it on the spotlight in 2009. And that IS on the Miller/Giambrone regime (among others).
But, hey, what's done is done. Miller isn't perfect, as I said, but I still think it's a good thing that (as he told Paikin) he came out of the woodwork here, given what the province appears to be doing. But all this stuff cuts both ways. The "disaster" building the St. Clair streetcar allowed Ford to poison the well on LRT and it would be a damned shame if the "disaster" Ford II is now proposing allowed Miller and the proverbial downtown NDP crowd to poison the well for a true regional system. That is not what Ford is doing, I happily admit, but it's not something Miller seems to grasp the need for either.
(And I'm assuming the reference above to Miller not living here anymore was based on him having taught at Harvard for a bit but, yeah, he's been back for a while.)
