George Weston Limited fuels Canadians through those long winters. About 95% of the company's sales come from its 63%-owned Loblaw Companies Limited, Canada's largest supermarket operator (with more than 1,000 stores under some 20 banners including Loblaws, Extra Foods, T&T, and Zehrs Markets) and the country's largest wholesale food distributor. The rest comes from Weston Foods, with operations in Canada and the US that focus on freshly baked goods, frozen dough, biscuits, and other bakery products. (Its Interbake Foods division is a major supplier of Girl Scout cookies in the US.) Chairman Galen Weston owns about 63% of the company, which was founded by his grandfather in 1882.
