Two boats that burned overnight in a harbour in Ladysmith, B.C. have leaked fuel into the water, according to officials.

The Canadian Coast Guard confirmed crews attended the boat fire at around 3:30 a.m. in the south end of the harbour.

The majority of fuel and pollutants on board is thought to have burned up in the blaze, but a light sheen was still visible on the surface of the water Wednesday night.

A containment boom has been set up around the affected area by Western Canada Marine Response Corporation and the Coast Guard.

The sheen is not recoverable and is expected to evaporate within the next 24 hours, according to the DFO.
