HALIFAX -- An Air Canada plane made an emergency landing at Halifax's Stanfield International Airport on Friday evening.

Air Canada said the pilot of Flight 623 reported an "acrid odour" shortly after takeoff from Halifax and returned as a precaution.

Initial reports suggested smoke in the cockpit, but an Air Canada spokesman said that was not the case.

The Embraer 190 regional jet was bound for Toronto with 66 passengers on board.

Air Canada said the plane landed normally and there were no injuries reported.

Passengers were expected to be put on a later flight.

The aircraft was to be inspected to determine the cause of the odour.
