May Day rally, Vancouver Technical auditorium

David Cadman, civic union representative and member of the Committee of Progressive Electors, addresses May Day rally in Vancouver. In the 1970s and 1980s May Day rallies were a major affair with speeches by both NDP and Communist Party representatives. May Day events were later to involve a series of events throughout the month under the banner, Mayworks. In the 1990s May Day events waned, the likely victim of the decline of left forces following the dissolution of the Soviet Union in 1992.
