John Diefenbaker’s critics say he was a paranoid, antiquated, madman. Except the public loved him and the "Prairie populist" won three elections. Diefenbaker instinctively took the side of the underdog. He fought for Canadian values. He advanced the cause of liberty and freedom by opposing all forms of discrimination and by resisting government overreach into the lives of everyday Canadians. The record shows that Diefenbaker sided with indigenous Canadians more so than any prime minister. He also overcame early setbacks to pursue his vision of a Canada without systemic discrimination or hyphenated identities. In this meticulous, evidence-based, and compelling sweep of John Diefenbaker’s life and legacy, bestselling author Bob Plamondon reveals that Canada’s thirteenth prime minister is underrated by historians and deserves to be followed and recognized as one of our greatest leaders. The evidence reveals that Diefenbaker’s decisions as prime minister were wise, prescient, and have endured. He was often out of step with Canadian elites but was rarely disconnected from the people or on the wrong side of history. John Diefenbaker was Canada’s freedom fighter.
