No one complains about NY, London, HK real-estate because it's already understood to be expensive in the mainstream.
But Toronto real-estate being expensive is relatively new such that you have people who grew up in Toronto not being able to afford it in adulthood.
People are slowly realizing that TO is now just another global city out of reach to the middle class unless you make heavy comprises. Give it some time, and soon people will stop complaining about being able to buy a house with a backyard here as well.
