much of Dundas Square is under the Helicopter flight path for St Mikes and Sick Kids, which makes really tall buildings impossible.It's quite strange that Yonge and Gerrard will have one of the strongest concentration of tall buildings.
I think it should have been Yonge and Dundas. Just like Times Square. It's hemmed in by tall buildings. Dundas Sq lacks that feel but hopefully that will change.
