Historical rankings of prime ministers of Canada

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.

East Block (left) and the Office of the Prime Minister and Privy Council (right) have housed the office of the prime minister since Canadian Confederation, the former from 1867 to 1977 and the latter since 1977.

Scholar survey results

Canadian custom is to count by the individuals who were prime minister, not by terms.^[1] Since Confederation, 24 prime ministers have been "called upon" by the governor general to form 30 Canadian ministries.^[1]

1. Served less than 2 years, 3 months as prime minister, while all others served for more than 4 years, 11 months. There is a strong correlation between time served in office and the poll rankings: the bottom quartile of the aggregate poll rankings are all in the bottom quartile of time served in office. Similarly, the top four prime ministers in terms of aggregate rankings are in the top four of time spent in office.
2. Ranking calculated before the prime minister had left office.
