Pat Burke, one of the top executives at Scotia Capital, left the firm suddenly Thursday.
Mr. Burke was promoted in June to the role of co-head of global equities and advisory at the firm, which is owned by Bank of Nova Scotia.
That was part of a change of Scotia's leadership structure by Mike Durland, who became sole chief executive of the firm a few months prior. That put Mr. Burke one rung below Mr. Durland.
Mr. Burke's departure was for personal reasons and was effective immediately, the firm told employees in a memo distributed early Thursday evening. A Scotia spokesperson confirmed the departure Friday.
Pruyn Haskins has been promoted to take Mr. Burke's place.
Mr. Burke had been with Scotia for six years. In his most role as co-head of global equity and advisory, he oversaw numerous businesses that were key for the securities firm.
Those included stock trading, the division that runs stock sales for companies and the investment bankers who advise companies on deals.
Prior to his promotion, he was head of global equities. That was also a very senior role that put him in charge of all stock traders, equity analysts, and the traders who dealt in derivatives based on stocks.
Prior to coming to Scotia, he was head of Canadian equities for Merrill Lynch.
