The NDP stands for the New Democratic Party, which is a federal political party in Canada. The party was founded in 1961 by the Co-operative Commonwealth Federation (CCF) and the Canadian Labour Congress (CLC) and is widely described as social democratic, occupying the center-left to left-wing of the political spectrum. The party supports a mixed economy and broader welfare, and its ideological orientation includes social justice, equality, and environmental sustainability. The federal and provincial (or territorial) level NDPs are more integrated than other political parties in Canada, and have shared membership (except for the New Democratic Party of Quebec). The NDP has never won the largest share of seats at the federal level and thus has never formed government. From 2011 to 2015, it formed the Official Opposition; apart from this, it has been the third or fourth-largest party in the House of Commons. The NDP governs the provinces of British Columbia and Manitoba, forms the Official Opposition in Alberta, Saskatchewan, and Ontario, and has sitting members in every provincial legislature except those of Quebec, New Brunswick, and Prince Edward Island.
