Check out the Woodbine’s redevelopment plan. Hundreds of acres next to Pearson airport and on rapid transit to downtown Toronto and the rest of the tech corridor. Amazon will go to Toronto and locate there. Toronto to Waterloo corridor has the highest concentration Per Capita of tech startups and engineers after Silicon Valley. It avoids US immigration nonsense and has free healthcare that saves hundreds of millions per year.

Of course there's land. You just have to convert low-intensity use to high-intensity use. Go east on Bloor past Spadina, and you'll find plenty of two-story commercial buildings right on a subway line. Any of those blocks could be redeveloped into skyscrapers.

Suburb region of Durham is part of the bid...there's LOTS of land left there.
