They have double the number of buildings that are 200+ meters. That will take quite a bit of time to surpass.
Although that is true, and actually really interesting, if you increase the value up to 300+m it changes too:
Toronto: 1 (which is under construction)
And again within that 7, two of them are over 400m with another one over 350
I just can't really take a list too seriously that has Oxford Place in it and The One listed as under construction
