The Canadian Civil Liberties Association or CCLA, is a non-governmental organization in Canada that is devoted to the defense of civil liberties and civil rights.
The CCLA was founded in 1964 and is based in Toronto, Ontario. Its current president is Marsha Hanen, who is also a former president of the University of Winnipeg. Alan Borovoy has been the CCLA's general counsel since 1968.
The Association notably spoke out vigorously against the 1970 invocation of the War Measures Act by then Prime Minister of Canada Pierre Trudeau in response to the October Crisis in Quebec.
The CCLA's records are preserved at Library and Archives Canada.
