The province says the Calgary-based trucking company, Executive Flight Centre, will be responsible for all cleanup costs after one of their trucks crashed into Lemon Creek on Friday.
Crews have now removed the tanker truck, but officials are warning residents of the Slocan Valley that the water is still not safe to use after 35,000 litres of jet fuel leaked from the tanker.
Officials say most of the fuel will eventually evaporate, but residents are being warned not to swim downstream of the spill, or to drink from the river.
Many concerns remain about the impact to the environment in the area.
An evacuation order was issued for residents in the area on Friday night after the spill happened just before 5 p.m.
