In his Speech from the Throne for the Opening of the 6th Session of Canada’s 18th Parliament on January 25, 1940, Governor General Lord Tweedsmuir promptly announced that Parliament was being dissolved. The Session was over before it even started and the Liberal government of William Lyon Mackenzie King was going to the polls.
Half a year earlier, the 5th Session of the 18th Parliament lasted only six days. King had it prorogued shortly after Canada declared war on Germany. He assured the Opposition Leader, Robert Manion, that there would be another session held before an election was called. It’s doubtful Manion anticipated that the next session would actually last for 0 days.
