Sam Gindin is a Canadian intellectual and activist known for his expertise on the labour movement and the economics of the automobile industry.

The National Automobile, Aerospace, Transportation and General Workers Union of Canada, commonly known as the Canadian Auto Workers (CAW), was one of Canada's largest 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), Ken Lewenza (2008–2013), and Jerry Dias (2013–2022) when the CAW became UNIFOR.
