Confederation of National Trade Unions president Jacques Letourneau said Friday one of its affiliates, which represents 6,000 prison guards, will campaign against the Tories in certain Quebec ridings and in Ontario, particularly in the Toronto area.
The 325,000-member labour group also represents Radio-Canada employees and will campaign for more financing for the CBC's French-language network, which has been hit by various cuts in recent years.
Earlier this year, Stephen Harper's Quebec lieutenant challenged union leaders to run against the Tories during the next federal election.
Denis Lebel was responding to comments from Quebec's largest labour group it would do everything it could to prevent the Conservatives from winning seats in the province.
The Quebec Federation of Labour also promised to work with other union groups across Canada to forge a policy of voting strategically against the Tories in the election.
In Quebec, the Confederation of National Trade Unions will target three specific regions where it believes the Tories are vulnerable: the Eastern Townships; Saguenay-Lac-Saint-Jean, about 250 kilometres north of Quebec City; and Chaudiere-Appalaches, near Quebec City.
Letourneau defended the union's strategy and said it is perfectly legitimate for the labour movement to get involved in politics.
The Conservatives responded Friday, saying unions should respect election laws and have to make public the sums of money they spend during this fall's campaign.
