I go to Toronto a few times a year and each time I am astounded by the number of tall buildings. Montreal is not a small city (over 3.5 million in the Greater Montreal area) but because of our "mountain" there is a limit on the height of buildings. Toronto seems to like to build high. Across from our hotel they are building a 50 story condominium. Not only is the height sky high, but the prices are too. Toronto is a business city. Montreal is a little more laid back.
