The One Big Union (OBU) was a militant left-wing industrial union based primarily in Western Canada.[1] Launched formally in Calgary on June 4, 1919, the OBU, after a spectacular initial upsurge, lost most of its members within a few years. It eventually merged with the Canadian Labour Congress in 1956.
