A coalition government, or coalition cabinet, is a government where political parties enter a power-sharing arrangement of the executive. Coalition governments usually occur when no single party has achieved an absolute majority after an election. A party not having majority is common under proportional representation, but not in nations with majoritarian electoral systems.

The Parti bleu was a political group that contested elections in the Eastern section of the Province of Canada. The Blue Party was ideologically located on the political right, and was defined by its support for the Catholic Church, and later for supporting confederation.
