I want to challenge the notion of Toronto's golden era past. This theme is common everywhere and let us not forget, was the prevailing attitude towards western civilization for much of it's history.
Toronto is a different, not worse or better, place than it was decades ago. We want to attribute an exceptualism to our history but really the maturing of a city is really more a function of it's size and the establishment of entrenched social order. We can look at individual issues like say litter, and compare the past and the present. However, really you cannot poach individual aspects of society in the past and view them in isolation from contemporary reality.
On the issue of collective sense of destiny, I believe this to be a real phenomenon. However, it is also representative of an immature period in a cities development. Toronto was to put it bluntly a simpler, less competitive, smaller place at the time. The malaise we are experiencing today is a function of rising competitiveness, sophistication and complexity. Let me emphasis again that we should not take this as meaning good or bad. There are positive and negative aspects. Toronto is growing and transforming now just as fast or faster than in the past. I'm not talking about population or buildings or infrastructure, but in terms of the far more important social order. A complex sophisticated city has more specialization, diversity and opportunity for the highly competitive. However it tends to fail at delivering the "tide lifts all boats" kind of general opportunity that characterized the development of the city in the 60's, 70's and 80's.
I think as the kind of architectural and design standards that people on this forum desire start to come to fruition it starts to mark the transition of the city towards an entrenchment of the social order. The beauty of Toronto I think has always been the promise of a place were diversity, complexity and sophistication could exist while providing the chance for opportunity and prosperity for all. Our greatest challenge in the future will be to enhance the former without sacrificing the latter.
