The Globe and Mail reports in its Thursday edition that Mike Durland, the head of Bank of Nova Scotia's global banking and markets division, has become the latest in a long line of executives to leave the bank since Brian Porter took the top job. The Globe's David Berman writes the shakeup continues a whirlwind of activity at the top levels of Scotiabank under Mr. Porter. Since becoming chief executive officer in November, 2013, Mr. Porter has appointed new regional heads for Latin America and Mexico, as well as a new chief risk officer, chief operating officer, capital markets head, wealth management head and marketing head. Mr. Durland took full responsibility for his current role in 2014. Dieter Jentsch, group head of international banking who oversaw Scotiabank's recent investor day in Mexico City, will take over Mr. Durland's role. Ignacio Deschamps will take over from Mr. Jentsch as group head of international banking, overseeing Scotiabank's extensive operations outside Canada. Mr. Deschamps's title will also include oversight of digital banking. The changes come amid tremendous shifts in the Canadian banking sector. Canadian bank stocks have fallen more than 7 per cent this month alone.
