I'm sorry I went on a tangent but if stopping real estate flippers means cancelling every unique project in the city then it is well worth the price. Took a look at MLS and compared Toronto {scar, et, ny, old city} to a similar area of Vancouver {nv ,wv, bur, rich and van city}/ In Tor there are about roughly 580 homes under $900k while in Vancouver there is a grand total of 5, two of which are in the ever exclusive Downtown Eastside.
Great buildings are great to have as long as they for the people who live in the city and not just for passport buying, speculation, and money laundering. It can totally destroy a city and its character as Vancouver clearly exemplifies. Housing of all types should be to the benefit of the city, its citizens, and community and not help lead to its demise and if that means no Mirvish & Gehry project then so be it.
