Some of Canada's best known artists have added their voices to opposition against the Enbridge Northern Gateway pipeline project.

Robert Bateman and Carol Evans are two of the artists whose works will be exhibited as part of the Art for an Oil-Free Coast exhibit, which opens Monday in Calgary. The donated original art will be sold at auction with all the proceeds going to Raincoast Conservation Foundation's oil-free coast campaign.

"It's the artists expressing their love of the B.C. coast and their fear for oil tanker traffic on the West Coast," says exhibit spokesman Brian Falconer.

If the pipeline project goes ahead, oil produced in the oilsands would be piped to a tanker port in Kitimat and then shipped to international markets.

Opponents of the pipeline are concerned about the environmental consequences, including a potential spill into B.C.'s forest and waters.

The show opens in the Calgary Public Library at 6 p.m. MT Monday and will move to the City Hall Atrium afterwards.

Admission is free.
