An Air Canada plane bound for Vancouver was forced to dump fuel and return to Sydney on Thursday after crew reported smoke coming from an oven in the galley, the airline said.

The Boeing 777 aircraft landed safely without incident, according to a Sydney Airport spokesman.

Air Canada's general manager for Australia and New Zealand Jeannie Foster was quoted by local media as saying the plane returned to Sydney as a precaution, denying earlier reports of a fire.

"A crew member saw smoke come out of the oven in the galley and informed the captain. The captain took the precaution to return to Sydney... No emergency was declared. There was no fire, only smoke," she was quoted as saying on Sky News.

She added the aircraft was expected to leave for Canada later on Thursday.
