League For Socialist Action (Canada) - League For Socialist Action

In 1961, the SEL and SIC merged and became the League for Socialist Action (LSA), with branches in Toronto and Vancouver.

Outside Toronto near Orono the LSA had a camp property called Camp Poundmaker named after the famous Plains Cree leader. The camp song was a comic parody and it went like this: Camp Poundmaker's the place for me/Far away from the bourgeoise/Steady and true/I'll be to you/Loyal to the LSA-LSO/Raise on guard the red flag/Cheer it with all your might/Hurray for Camp Poundmaker/Hurray for Camp Poundmaker, maker, Camp Poundmaker!

The LSA marked the resumption of open Trotskyist activities in Canada after almost a decade of underground work. In 1964, a branch was established in Montreal under the name Ligue Socialiste Ouvrière. A youth wing, the Young Socialists, was also established in 1964; its branch in Quebec was known as the Ligue des Jeunes Socialistes.

Members of the LSA were involved in the Waffle movement of the CCF's successor party, the New Democratic Party (NDP), from 1969 until the expulsion of the Waffle from the NDP in 1972. The LSA decided to remain in the NDP.

In the early 1970s, the United Secretariat of the Fourth International (USFI, which was the result of a 1963 reconciliation between the ISFI and the ICFI) was riven by an international faction fight. The majority and leadership supported the USFI faction associated with the Socialist Workers Party (United States).

Supporters of Ernest Mandel, many of whom were active in the student movement, coalseced at the 1973 convention of the LSA as the Revolutionary Communist Tendency, a minority tendency that ultimately left the LSA to join the Revolutionary Marxist Group which supported Mandel internationally. Amongst its leadership, Alain Beiner, Ruth Bullock, Al Cappe, Joan Newbigging, John Riddell, Ernie Tate and Art Young were signatories of the 1973 Declaration of the Leninist Trotskyist Tendency, supporting the SWP position in the USFI. In 1976, Bullock, Riddell, Tate and Young were among the signatories of a document, "The Verdict", supporting the SWP leadership against allegations made by Gerry Healey.

Dowson and his supporters, meanwhile, found themselves reduced to a minority within the LSA due to criticism of Dowson's sympathy with Canadian economic nationalism. They left the LSA in 1974 to form the "Socialist League" which became known as the "Forward Group" after the name of its publication.

In 1977, supporters of the Revolutionary Marxist Group and a separate Quebec organization, the Groupe Marxiste Revolutionnaire, united with the League for Socialist Action and the Ligue Socialiste Ouvrière to form the Revolutionary Workers League/Ligue Ouvrière Révolutionnaire which became the new Canadian section of the USFI.
