Who Killed Canadian History? is a 1998 book by Canadian historian J. L. Granatstein. The book argues that Canadians lack national unity because of their failure to teach their country's history. Granatstein contends that multiculturalism, social historians and weak history teaching standards are responsible for Canada's lack of a historical narrative. He advocates for a greater emphasis on the study of Canadian history in schools and university history departments, especially political and military history.
