The party followed a Maoist political program and was part of the broader New Left movement.
The most prominent former member of the Workers' Communist Party is Gilles Duceppe, former leader of the Bloc Québécois and former Leader of the Official Opposition in the House of Commons of Canada.
Duceppe called his membership "a mistake" based on a search for "absolute answers" during his youth.
She later became a trade union leader and a cabinet minister in British Columbia.
The Workers' Communist Party nominated 30 candidates in the 1980 Canadian federal election and 33 in the 1981 Quebec general election; the party achieved its best result in the latter, receiving 4,956 votes, or 0.14% of the provincial total.
