Cost of everything and value of nothing.
It's a problem when the bare minimum is acceptable and developers of low-or-no integrity, interested exclusively in every last drop of profit, who nurture no personal emotional investment in Toronto, are allowed to cobble together something at rock-bottom costs. Skyscrapers are manifestly
not inconspicuous, and will stand for many decades or centuries. Of equal importance is that human beings inhabit these buildings, pay a mint to buy or rent, and shouldn't have to tolerate on-the-cheap, ramshackle interiors and elevator ratios suitable for herding cattle. We as citizens, and Toronto as a governing body comprised of people who live here, should demand better.
I should add the proviso that I am not as critical of Toronto architecture as most others here. With regard to skyscrapers, I am partial to rectangular, boxy massing (I hate angular buildings), and I prefer Toronto-style balconied skyscrapers to monolithic slabs of plain blue or grey glass. (Though, contradictorily, I must be one of the few people here who likes B-A West.) For example, purely personal taste, but I am glad we have very little of London's weird architectural shapes (the Egg building; the Shard; the walkie-talkie; "no, thanks" to all).
I am much more bothered by the shabbiness of large parts of Toronto's public realm. On that score, Toronto falls far short of world-class, and we should be embarrassed. That is the fault of a perennially cash-strapped city, a provincial government that is hobbling the city at every turn, and citizens who don't care or feel disempowered. Collectively, we no longer take pride in living in a city that is clean, tidy, well-maintained, and perhaps most importantly, designed/redesigned with intelligent purpose and aesthetic considerations. UrbanToronto should found a community group of volunteers who champion such things and lobby City Hall to that effect.
