Spill happened on a perfectly calm day during bunkering operation and was not reported by the vessel's master.
The vessel is reportedly only three months old and was on her maiden voyage to Vancouver.
Spill more significant than originally reported, and with an approaching storm, the bunker fuel is washing up on beaches of both north and south of Fraser River banks.
Also, a very slow response by Canadian Canadian Coast Guard to contain the spill made the spread worse.
