Unfortunately office tower height is based on demand, and in a country like Canada where the population is only 36 million....you simply aren't going to get the massive office towers. We don't have the big companies like the US, and most developers don't want to propose these 60 storey 2 million sq ft towers only to never get them built. Instead they go with the 40-50 storey 1 million sq ft towers..... which all seem to be in the 150-240m range. That's what our economy demands and that's what we get.
I personally am happy these towers ended up being the height they are. Yeah an extra 10-20m would have been perfection, but I'll take this rather than nothing. Once the crowns are added, and the lighting....trust me....they won't be blending in with anything.
