After the
1921 election, the
Progressive Party, a looseknit largely agrarian "protest" party, won the second largest number of seats to
William Lyon Mackenzie King's Liberals, but declined to be the Official Opposition because of their lack of national organization. The third-place Conservative Party, led by
Arthur Meighen, thus became the Official Opposition. As a result of the
1925 election, the Official Opposition was actually the largest party in the House of Commons, the Conservatives. The Liberals, led by Mackenzie King, were able to form a
minority government despite the fact that they had a dozen fewer seats than the Conservatives because King's Liberals were able to win the support of the Progressives to remain in government. Similarly, in Ontario, the
Ontario Progressive Conservative Party had the largest caucus but were relegated to official opposition not long after the 1985 election, as their minority government was defeated on a motion of non-confidence. The
Ontario Liberal Party, the second largest party, governed from 1985 to 1987 with supply provided by the
Ontario New Democratic Party. In 1993, the
Reform Party challenged whether the
Quebec sovereigntist Bloc Québécois could hold the position of official opposition. The
Speaker ruled in favour of the Bloc, as they held two more seats than Reform. During the Bloc's time as the official opposition, Quebec issues on national unity dominated Question Period, often to the irritation of the other opposition parties (indeed, Reform was the only other caucus that met
official party status, with the NDP and PC parties falling short of that threshold). However, Reform was considered to be main opposition to the Liberals on all other issues that were not specific to Quebec. In 1995, when Bloc leader
Lucien Bouchard's position as Opposition Leader granted him a meeting with the visiting
American president,
Bill Clinton, Reform leader
Preston Manning was also given a meeting with Clinton in order to diffuse Bouchard's separatist leverage.

Parliament Hill, February 28, 2018 In 1987, the
Liberals won every seat in the
51st New Brunswick Legislative Assembly. To ensure the proper functioning of the parliamentary system, Premier
Frank McKenna named several members of his own caucus, led by
Camille Thériault, to serve as the Official Opposition. The government also allowed the
Progressive Conservative Party, which finished second place in the election in the number of votes received, to submit written questions to ministers during Question Period. ==Privileges==
