#2. Galen Weston
Major holdings: George Weston, Associated British Foods, Loblaw Cos., Selfridges, Holt Renfrew
When Weston took control of his family’s chain of Loblaw’s grocery stores—now helmed by his son Galen G.—he saved the floundering company by closing dozens of stores, upgrading the remaining locations and wooing new talent, such as future marketing legend Dave Nichol. Weston now works on fostering a dynamic business community in Canada, supporting The Next 36, an incubator program for innovative young entrepreneurs.
