National unity government

A national unity government, government of national unity, or national union government is a broad coalition government consisting of all parties (or all major parties) in the legislature, usually formed during a time of war or other national emergency.

During World War I the Conservative government of Sir Robert Borden invited the Liberal opposition to join the government as a means of dealing with the Conscription crisis of 1917. The Liberals, led by Sir Wilfrid Laurier refused; however, Borden was able to convince many individual Liberals to join what was called a Union Government, which defeated the Laurier Liberals in the fall 1917 election.

During World War II, the opposition Conservative Party ran under the name National Government in the 1940 election as a means of promoting their platform of creating a wartime national government coalition (evocative of the previous war's Union government). The party was not successful in the election, which re-elected the Liberal government of William Lyon Mackenzie King, whose party continued to rule alone for the duration of World War II.
