  After exiting office, former prime ministers of Canada have engaged in various pursuits. Some remained in politics: Bowell continued as a senator, and Bennett moved to the United Kingdom after being elevated to the House of Lords. A number were leaders of the Official Opposition: John A. Macdonald, Arthur Meighen, Mackenzie King, and Pierre Trudeau, all before being re-appointed as prime minister (Mackenzie King twice); Alexander Mackenzie and John Diefenbaker, both prior to sitting as regular Members of Parliament until their deaths; Wilfrid Laurier dying while still in the post; and Charles Tupper, Louis St. Laurent, and John Turner, each before they returned to private business. Meighen was also appointed to the Senate following his second period as prime minister, but resigned his seat to seek re-election and moved to private enterprise after failing to win a riding. Also returning to civilian life were: Robert Borden, who was Chancellor of Queen's and McGill Universities, as well as working in the financial sector; Lester B. Pearson, who was Chancellor of Carleton University; Joe Clark and Kim Campbell, who were university lecturers, Clark also consultant and Campbell working in international diplomacy and as the director of private companies and chairperson of interest groups; while Pierre Trudeau and Jean Chrétien returned to legal practice. Former prime ministers also commonly penned autobiographies—Tupper, for example—or published their memoirs—such as Diefenbaker and Paul Martin.
