On Monday, November 7, 2016, I made what I thought were the final edits to the manuscript of my latest book, The New Urban Crisis, and sent it off to my publisher. The next day, my wife and I invited our American friends to come to our house in Toronto to celebrate what we were all but certain would be Hillary Clinton’s election. We pulled out all the stops. We hung up red, white and blue bunting, and dressed our baby and our puppy to match. My wife’s sisters supplied us with life-sized cutouts of Clinton and Donald Trump, which they had literally “muled” over the border from the Detroit suburbs. At 6 p.m., when the polls began to close, we turned on the TV to watch the early returns. By 8:30, the party had come to a crashing stop. I spent the rest of the night glued to Twitter; I hardly even noticed when the last of our guests departed.
