Masrani, who has served as CEO for a decade, steps down amid a major money laundering scandal in the U.S., which has led TD to reserve US$3-billion for potential penalties. Chun, a TD veteran with 32 years at the bank, has managed the wealth management and insurance sectors prior to his current role. Despite his relatively short nine-month tenure leading the profitable Canadian personal and commercial banking division, his promotion comes as part of a larger executive reshuffle at TD.
