Isn't the word "Manhattanization" is bit sensationalization?
I like one comment under the news report, and I quote:
"Manhattan does not have a few dozen massive towers dwarfing a sea of detached private homes with front lawns and back yards, which is what's happening in downtown Toronto. Instead, Manhattan has streets of brownstones (basically large townhouses) and midrise buildings about 6 to 15 storeys. To get to the true Manhattanization, Toronto needs to get rid of inefficient private detached homes and old two-storeys, which ain't gonna happen anytime soon. That, and some decent transit."
Downtown Toronto will never be "Manhattanized" and will never look and feel like Manhattan.
