A member of the same intellectual generation as Harold Innis, Northrop Frye, and George Grant, Donald Creighton (1902–1979) was English Canada’s first great historian. The author of eleven books, including The Commercial Empire of the St. Lawrence and a two-volume biography of John A. Macdonald, Creighton wrote history as if it “had happened,” he said, “the day before yesterday.” And as a public intellectual, he advised the prime minister of Canada, the premier of Ontario, and – at least on one occasion – the British government.Yet he was, as Donald Wright shows, also profoundly out of step with his times. As the nation was re-imagined along bilingual and later multicultural lines in the 1960s and 1970s, Creighton defended a British definition of Canada at the same time as he began to fear that he would be remembered only “as a pessimist, a bigot, and a violent Tory partisan.”Through his virtuoso research into Creighton’s own voluminous papers, Wright paints a sensitive portrait of a brilliant but difficult man. Ultimately, Donald Creighton captures the twentieth-century transformation of English Canada through the life and times of one of its leading intellectuals.
