2015 wouldve have been achievable if it wasnt for the budget cuts. They were forced to spread out the schedule more iirc. The 12 year statement is a bit flawed as their plan was to phase it in. hwy 7 opened in 2011 ahead of schedule in fact. IMO for those who are comparing LRT vs BRT, laying track is the easy part. Widening the road for the ROW and utility relocation is the hard part at which they did a pretty good job at managing. I live near hwy 7 so I can tell first hand how it affected traffic which wasnt that bad vs the surface sections of the ECT. They only started major work on yonge st (major road work, not utility relocation) a few years ago and if they are completing it this year its fine. Whether itd be used heavily enough to satisfy the appetites of transit fanatics is irrelevant. They at least got things done in their stated timelines and relatively on budget, unlike ECT, YUSE, SSE.2019 was said a few years ago, but was far behind the initial schedule.
These projects were initially funded around 2008 I believe, along with Transit City. At the time the deadline was 2015 I think. 12 years to complete some bus lanes is agonizingly slow by any standards. And Yonge Street, the most important lanes, still aren't done.
Plus you have the whole issue of these lanes being way, way under-serviced.
