Several of its candidates were elected to the Legislative Assembly of Manitoba and it counted federal Members of Parliament J. S. Woodsworth[1] and A. A.
The ILP was founded in December 1920 by disgruntled members of the Dominion Labour Party, who left that organization when it was taken over by rightist elements.
Most of these Members of the Legislative Assembly (MLAs), including parliamentary leader Fred Dixon, were part of the exodus from the DLP to the ILP later in the year.
(The CLP was, in any case, a fairly weak organization in Manitoba, and the ILP leaders had little incentive to merge with their smaller rival.)
The CCF was formed in 1932 to expand the parliamentary left's support base beyond the urban working class, and many in the ILP were suspicious of this.
