Participation Quebec was founded in November 1976. It was a non-profit public interest organization dedicated to bringing together the anglophone and francophone communities in Quebec. Participation Quebec was non-partisan and was not affiliated with any other organizations until its eventual merger with Alliance Quebec. The organization was incorporated under the laws of Quebec and was registered as a charity for tax purposes. In 1978, the members of its executive were Michael Prupas (President), David Steward (Treasurer) and François Goulet (Executive Director). At that time, the organization had approximately 200 members.
According to Participation Quebec, it's goals were: "to have a positive influence on the policies of education and governmental institutions which promote the isolation of cultural groups within Quebec, or which are prejudicial to the building of a Quebec for all Quebecers" and "to improve the relations between the French and non-French speaking communities in Montreal." Throughout its years of Operation, Participation Quebec hosted symposiums, formed committees, sponsored meetings with government officials, prepared and tabled briefs, held press conferences, and organized speaker series, among other activities.
In May 1982, Participation Quebec and other anglophone rights organizations, including the Positive Action Committee, merged with Alliance Québec.
