Maybe the OP is thinking that $3.5B spent on one stop would be better spent on the DRL.  The original Transit City LRT was fully funded and in that lower density situation, would have sufficed.
Needless to say, TO needs more subways, LRTs, rapid bus, and other mechanisms to alleviate the traffic and congestion.  Billions in lost productivity are wasted each year because of short-sighted politicians thinking only of their own best interests.  Hopefully Tory will step up and be the leader TO needs,
