The Winnipeg Declaration, sometimes referred to as the Winnipeg Manifesto, was the programme adopted by the Co-operative Commonwealth Federation (CCF) in Canada to replace the Regina Manifesto.
It also reflected the increased pragmatism that had coloured the party since it took power in the province of Saskatchewan.
The anticommunist mood of the Cold War also caused the CCF to seek to moderate its stance.
The CCF federal vice-president and future New Democratic Party leader, David Lewis, was instrumental in drafting the document and having it approved.
The Regina Manifesto declared that the CCF would not rest until capitalism was "eradicated," but the Winnipeg Declaration affirmed, "The CCF will not rest content until every person in this land and in all other lands is able to enjoy equality and freedom, a sense of human dignity, and an opportunity to live a rich and meaningful life as a citizen of a free and peaceful world."
