Real Estate in TO is expensive, but nowhere near SF.

SF has:

A) Earthquakes B) The Bay is a hodgepodge of cities. TO is mostly one big city under the same management. C) SF has quirky and specific views of 'how they ought to be'. Oddly conflicting at times.

There's plenty of geography around the Bay - there's no reason that SF 'has to go vertical' while the other areas don't.

Too much blame on SF.

If it's safe to put 25 story residences in SF surely it is also in Palo Alto and Freemont etc..

Or maybe tech could find another hub?

Toronto added 400k people in last 5-year census period, for a total of ~9% growth. The 5 years before that were similar. It is both the largest and the fastest-growing city in Canada.
