More than 4,000 people have registered to speak at hearings about the proposed Northern Gateway pipeline.
The pipeline would ship oil sands crude to supertankers on the B.C. coast at the port of Kitimat.

A federal review panel will start hearing oral statements in January and make a recommendation by the end of next year.
