Canadian Oil Sands Ltd said normal operations have resumed at Canada's largest synthetic crude project, Syncrude, following a fire in August.
The company is the largest stakeholder in the oil sands project in northern Alberta.
Syncrude had been running at reduced rates since a Aug. 29 fire at an upgrading plant.
There are six other partners in the Syncrude joint venture - Imperial Oil (IMO.TO), Mocal Energy, Murphy Oil (MUR), CNOOC Ltd unit Nexen, Sinopec and Suncor Energy (SU) .
Shares of Canadian Oil Sands were almost flat at C$6.18 on Friday on the Toronto Stock Exchange.
