The Cooperative Commonwealth Federation was a political party in Canada that formed during the Great Depression. Most of its support came from the rural cooperative movement among farmers. Cooperative members made up a large part of its voters, and many of its leaders had held elected posts in cooperatives. Organized labor was another important part of its base of support. So, when the CCF took control of the provincial government of Saskatchewan in 1944, it passed legislation to increase the power and membership of the organization that made up its base of support.
