I think Jane in York Region has a good case for a Parisian-style tram, if we could build it for Parisian costs and operate at Parisian speeds from the Vaughan Hospital hitting Canada's Wonderland, Vaughan Mills, VMC, and possibly Highway 407 (if we get a 407 line there someday) achieving a ~10 minute travel cut. The Barrie Line is close enough to provide an express connection downtown and the Jane ROW is quite wide, albeit I don't know how much of that is reserved.
But maybe this is a
fantasy thread discussion.
