Leader of the Official Opposition - Andrea Horwath
The opposition may be comprised of one or more political parties, and the leader of the opposition party with the second-most number of elected candidates after the government party is referred to as the Leader of the Official Opposition. A political party must have at least twelve elected Members to be considered a recognized party in the House.
Within the opposition is the shadow cabinet. The leaders of the opposition parties appoint Members to serve as critics for specific government ministries. As critics, the shadow cabinet scrutinizes the activities and policies of the ministries and may question Cabinet Ministers during the daily question period in the House.
