Yet we're building the most expensive thing in Toronto's history along Eglinton, a corridor with far fewer jobs than what Sheppard has now (especially Eglinton West, which has amongst the city's lowest job densities outside the Rouge Park and virtually no room for growth of any kind). The city has completely abandoned its suburban centre growth plan, so no wonder it failed to meet projections. Will the Spadina line/extension projections also fail to materialize? At least they're building the transit line first, something that didn't happen on Sheppard. Do boosteristic projections made 30 years ago have any relevance, anyway?
Still, trolls like you fail to note all the other jobs along Sheppard. Sheppard has the largest concentration of jobs and trip generators outside the YUS loop. North York General, Fairview, Consumers, all that industrial land between Kennedy and Markham...hell, extend Sheppard east of STC and you can hit Centennial, Centenary, and UTSC, which is tens of thousands of additional jobs and students. STC (the mall alone) is the biggest trip generator in the eastern half of the GTA. And this is all without the city giving a damn about supporting growth in the corridor. And it's a lot more than "a few condos."
Yeah, the DRL needs to be built first, as do Yonge and Danforth to STC extensions. We need to extend Sheppard as part of a $100 billion city-wide plan. It shouldn't be the priority before then, but it is needed. Maybe Sheppard would top out at roughly 20km long and 200,000 riders a day - wow, a subway line that isn't horribly overcrowded! How horrible!
