However, the Liberals had intentionally scheduled the mandatory "opposition days" (where a specified opposition party controls the agenda) on November 15 (Conservative), November 17 (Bloc Québécois) and November 24 (NDP). These days meant that any election would come over the Christmas season, an unpopular idea. Following negotiations between the opposition parties, they instead issued an ultimatum to the Prime Minister to call an election immediately after the Christmas holidays or face an immediate non-confidence vote which would prompt a holiday-spanning campaign.
