The Canadian Auto Workers (CAW; formally the National Automobile, Aerospace, Transportation and General Workers Union of Canada) was one of Canada's largest and highest profile labour unions. In 2013 it merged with the Communications, Energy and Paperworkers Union of Canada, forming a new union, Unifor. While rooted in Ontario's large auto plants of Windsor, Brampton, Oakville, St. Catharines and Oshawa, the CAW has expanded and now incorporates workers in almost every sector of the economy. The presidents of the CAW were Bob White (1985-1992), Buzz Hargrove (1992-2008) and Ken Lewenza (2008-2013).
