"Toronto, like all the world's cities, is being crushed into a bland, multinational corporate sameness that makes us all poorer, except for a few shareholders." That's a sharp way to put it. I'll add these two cognate comments, which came to mind just last week as I was reflecting on the same issue.
From the first chapter of Michael Tonello's 2009 memoir Bringing Home the Birkin (about making a living as a reseller of Hermès bags on eBay), reprinted in the NYTimes: "But lately I found myself becoming more jaded by my globe-trotting.[...] It was boredom. I had increasingly noticed a sinister sameness about each of these foreign cities."
From comments delivered by literary scholar Christopher Ricks at a Boston conference in 2009: "Every university and every school [...] has an identity crisis in this sense: that diversity within every institution has led to less diversity of institutions. It's a perfectly simple thing; every capital city in the world is more like every capital city than was the case when i was young because every capital city is now diverse. You can get English cooking -- which as we know is the greatest in the world -- in pretty much every capital city of the world. We have experienced an extraordinary increase in diversity and an extraordinary diminution of diversity, because every university, every Oxford and Cambridge college that used to be characterized by exclusivenesses which had a disagreeable side, and specializations or convictions, for which a price was paid. Keeble is the Oxford movement, and if you're in sympathy with those convictions, that is where you went; Jesus College is where you went if you were Welsh; and so on. They had an identify, they were open to the objection that they were not diverse, and what you had was a huge diversity of institutions. I'm not saying which of these two is to be preferred, I'm simply saying that, life being tragic as well as comic, you choose one and you do not get the other."
