Of course the Yonge and Bloor subways were full, they serve corridors 4* as long as Sheppard's. I'd say 50K for a 5 km stub is fair. It's better than many European, almost all US and some Asian systems. No one here believes that relief shouldn't come to those corridors. I'd even argue the Bloor subway isn't getting enough for relief. We're hear arguing merits of any extension. We just recieved 9 billion dollars from upper governments, and with 11.7 billion dollars available for the Relief line south, Waterfront Transit, the Scarborough subway, and crosstown east, we can now start looking at building even more for the future. Yonge north isn't a priority of toronto, and neither is Bloor West (Metrolinx should study that to take the place of milton corridor improvements). What's left? Relief line Long and U can't be started until the DRL and Scarborough subway are complete, which will likely take a good 10 years. After that, what's next? What if the relief line fails? What else will be built with relief line Long? What makes fiscal and political sense for the government to fund?
