Surveys have been conducted to construct historical rankings of individuals who have served as prime minister of Canada. These ranking systems are usually based on surveys of academic historians, economists and political scientists. The rankings focus on the achievements, leadership qualities, failures and faults in office.
Scholar survey results
Canadian custom is to count by the individuals who were prime minister, not by terms. Since Confederation, 24 prime ministers have been "called upon" by the governor general to form 30 Canadian ministries.
