List of ambassadors of Canada to the United States
This is a list of Canadian envoys to the United States, formally titled as Ambassador Extraordinary and Plenipotentiary to the United States of America for Her [His] Majesty's Government in Canada. Until 1943, Canada's representative had the rank of Envoy Extraordinary and Minister Plenipotentiary, after which the title was promoted to the rank of Ambassador Extraordinary and Plenipotentiary, while Leighton McCarthy had the job.
Most ambassadors have been political appointees to the job. A few (Chrétien, Pearson, Charles Ritchie, Edgar Ritchie and Wrong) were career diplomats or spent most of their career at the Department of External Affairs.
