The Canadian Coast Guard vessel Gordon Reid has managed to reach a disabled Russian ship and is towing it west away from Haida Gwaii.
The Simushir lost power and there were fears yesterday that it would run aground in the ecologically sensitive archipelago off B.C.'s north coast.
The Haida Nation has stated that the Russian boat is carrying 500 metric tonnes of heavy oil. It also has 60 metric tonnes of diesel.
If there's a spill, the heavy bunker oil could form tarballs that might kill scores of birds and marine mammals in the area.
According to a Toronto Star report, another Canadian Coast Guard boat and an American Coast Guard cutter are on their way to the area.
