The Environment Ministry confirms a CN Rail derailment has occurred at Hunter Creek, near Hope in the eastern Fraser Valley, but the ministry says no cargo is in the water.
A statement from CN says at least 20 rail cars carrying potash jumped the rails today as the train crossed a bridge.
The company says no one was hurt, no dangerous goods are involved and nothing burned.
A cause of the derailment is under investigation and the Transportation Safety Board says it will send a team to the site in order to determine what happened.
