Many people who live in all parts of the city care about the public realm or would care if it was raised in conversation, but somehow, these issues get marginalized. It doesn't matter what their background is. Toronto didn't start off as an industrial place, but rather a centre for Upper Canada, including its elites, but like countless cities grew to larger proportions through industrialization. (It should be noted that the French tried to start a settlement earlier in the 18th century as a trading centre which seemed to have done well upon the completion of Fort Rouille, but was in its infancy peripheral and sacrificed when France retreated from invading British forces in 1759.) Many working class people own and maintain attractive houses in Toronto. I don't think there's one particular narrative about how cities develop beauty in the public realm, for instance by people not being cheap. Sometimes it's all in the leadership of a mayor, a brilliant planner, the creative financing schemes of city hall bureaucrats, grassroots campaigns, influential critics in the media, big events, and decisions made in the city's formative eras. Whichever way that improvement is realized, people often start to love it and defend it once the results are clear, especially if there are economic gains.
