Yeah, I spent almost a year living there when I was younger and have been back a number of times. Those are my favourite cities in the world. Even the worst parts of central Paris are beautiful. I'll take their decrepit buildings anytime, although that was not the point of my comment. There are streets in Paris where a whole block is filled with beautiful buildings and most people appreciate having all that beauty in one place. I never suggested that every single street in Paris is lined with beautiful buildings, although I've never seen any areas of Paris that I would consider ugly. I've never been to the outskirts of Paris, where I've heard the worst parts are.
I don't think Toronto will ever be plagued by having streets with too much beauty. In fact, it's quite the opposite. We have very few architectural masterpieces. Most people I know, are underwhelmed by our boring architecture. We need all the help we can get, when it comes to beautiful buildings.
