Unifor is a Canadian general trade union founded in 2013 as a merger of the Canadian Auto Workers (CAW) and Communications, Energy and Paperworkers unions. It consists of 310,000 workers, and associate members in industries including manufacturing, media, aviation, forestry and fishing, making it the largest private sector union in Canada. In January 2018, the union left the Canadian Labour Congress, Canada's national trade union centre, to become independent.
