When Toronto author and critic Robert Fulford wrote a book about his hometown, he called it Accidental City. It is the deliberate design of Canadian immigration policies, however, that has allowed Toronto to become the world’s most ethnically diverse metropolis. Half of the city proper’s 2.5 million residents are foreign born; there are more than 150 languages spoken daily. A cool politeness pervades the streets – the legacy of Toronto’s early years as a British military post.
