New Brunswick's (Canada) McCain Foods is the world's largest producer of frozen french fries.

In August 1979 the New Brunswick Irving family purchased PEI frozen food producer C. M. McLean Limited, a PEI-based frozen vegetable and French fry producer. Irving's began marketing their frozen french fries as McLeans. This led to a legal challenge between the two very rich New Brunswick families, as McCains contended the name was too close to their brand. McCains won, and Irvings began marketing all their successful frozen food products under the brand "Cavendish Farms".
