As much as 'the left' is attacked on transit file, we've had two terms of 'right wing' Mayors who've accomplished very little. All of the project management and 'business' experience they claimed to bring to the table has had virtually no positive impact. Ford and Tory have not only not been able to stick to a budget, they've been incapable of even establishing a budget to stick to.
I don't think the TYSSE should've been built, but it was funded and under construction before Miller left office. The Eglinton LRT was under construction a year after he left office, and that's entirely in spite of Ford, who wanted it canceled.
Miller was far more successful than Ford and Tory at getting transit funded and built in Toronto.
