[12] Douglas was prime minister continuously from 1932 to 1953, normally this would only justify him being listed once, however the fact that the NPLP held a majority for his first and third terms, yet was in coalition with the Popular Party for the second term merits 3 separate listings.

[8] Elected after the failure of Sir Wilfrid was unable to bring to an end the Great Railroad Strike
[9] Coalition formed after the previous Bowell government faced loss of supply, primarily over the perceived failure to deal with the global "Grand Depression", which had left nearly a quarter of the nation out of work.
[10] A merger of the Progressives and Labours growing out of the old coalition.
[11] The NPLP was re-elected with a minority, thus the coalition. This government is best know for it's passing of universal socalized medicine.
[12] Douglas was prime minister continuously from 1932 to 1953, normally this would only justify him being listed once, however the fact that the NPLP held a majority for his first and third terms, yet was in coalition with the Popular Party for the second term merits 3 separate listings.
