Preliminary plans had a line from Don Mills to Pape. The DRL south would've been a subway line running from Pape south.Not too surprised some people are out of touch with the plans when not too long ago the Left's preferred Mayor wanted the DRL built as the Don Mills LRT on the surface.
Thank goodness cooler heads prevailed.
I wasn't a fan of that particular line, but I understood the need for higher capacity service - and it certainly wasn't set in stone at that point.
Personally I prefered the Mayor who was actually implementing sensible policies and getting things done. Miller is the Toronto mayor of the 2000s that best fits that description.
