Suncor Energy (TSX:SU) says executive Steve Reynish will act as interim chief financial officer as the company searches for a permanent replacement.
Reynish joined the oil and gas company in January 2012 as executive vice-president oilsands ventures.
He was formerly the president of Marathon Oil Canada.
Bart Demonsky announced in late November that he was resigning as CFO at Suncor to move to Canadian Pacific Railway (TSX:CP).
Suncor says the process to find a permanent replacement is expected to take several months.
