Development started moving out into what's now 905 in the 70s, really. The atmosphere south of Eglinton was decided hostile to development by 1965, and it shows in the downtown we have today, I think. It's broke, it hasn't created a net new job in my lifetime, and it's fusing its helium with pathetic projects like Dundas Square. If it weren't for yuppies wanting condos that keep the rest of us from ever having a hope of seeing Lake Ontario again, I don't think a building permit would have been issued after 1980. Most people who want to build something new these days look to Vaughan or Mississauga, or even beyond. "Donut Centre, what a hole" (thank you, Looney Tunes).
