Major company holdings: Maple Leaf Foods, McCain Foods
Maple Leaf Foods, currently under the stewardship of Wallace McCain’s son, Michael, continued tying up loose ends on a seven-year overhaul of the company’s operations. Its bakery division, Canada Bread, has been sold, factories shuttered and more than 1,000 jobs cut. But the resulting Maple Leaf is a leaner and more efficient operation, making it better able to compete with low-cost international meat processors.
