Suncor Energy has named company insider Peter Zebedee as its next chief executive and parted ways with finance chief Troy Little. The Canadian energy company said current President and CEO Rich Kruger will transition to the role of executive vice chair in April next year.

Zebedee, who now is Suncor's executive vice president of upstream operations, will be named president and CEO when Kruger makes his move. Suncor, whose operations span oil sands mining, offshore production, petroleum refining and the Petro Canada chain of gas stations across the country, said former Chief Financial Officer Little was no longer with the company.

It didn't disclose why he left but thanked him for his contributions. Zebedee will be appointed chief financial officer on Sept. 14, with oversight of all non-operating functions, the company said.
