People see what they want to see. As someone who loves both the CN Tower and aquariums, I couldn't be happier about the transformation down here.
It gets a bit much when people go on vacation and see some beautiful piazza or fountain or square in a foreign country and expect that here, too. They obviously ignored all the ugly bits and dark histories in those cities. Our city has cleaned up big time in the last 10 years...and with the 'green' movement, we are getting a ton of new (and sustainable) plantings all over the place.
