All it needs to be is not a box and it'll be taller. It pisses me off as well, but hey one tall tower will not make Calgary any closer to being a better city then Toronto. Calgary is in the midst of a boom right now, but it's not going to last much longer. They have an economy based primarily on one thing. Once all the companies are set up and all the jobs are filled Calgary is going to enter a very long era of stagnant growth. Toronto on the other hand has reached a point where growth is going to continue to happen no matter what. We have a much more diversified economy, possibly one of the highest amounts of foreign immigration on the planet and a shortage of space. Our super talls will come, possibly during, but guaranteed long after Calgary has reached the crest of the wave it's currently riding.
