CPCon) is an anti-imperialist group founded in 1949 by Canadian minister James Gareth Endicott in response to the new dangers to peace posed because of the Cold War.

[3] Active councils of the CPCon were established in: British Columbia, Calgary, Edmonton, Fraser Valley, Guelph, Halifax, Hamilton, Kamsack, London, Niagara, Peterborough, Saskatoon, Sydney, Thunder Bay, Vernon, Victoria, and Windsor.

Endicott remained the CPCon's chairman until 1971 when, according to his biography, he was pressured to resign by the leadership of the Communist Party for his pro-China views during the Sino-Soviet split.

By the late 1970s, members who had authored publications for the Peace Congress included scientists, artists, musicians and writers from across the country.

Although the Canada-wide Congress became inactive throughout the 1990s, by the mid-2000s an effort was made to re-establish Peace Councils in Edmonton and the BC Lower Mainland, in addition to Regina.

[5] A "Special Renewal Conference" was held in Winnipeg, Manitoba in 2008 which ratified the organization's constitution and politics and elected as president David McKee, a trade unionist, and past co-chair of the Canadian Peace Alliance.
