CP Rail spokesman Breanne Feigel said the incident happened about 12:45 a.m. on a CP Rail line in a remote area, about 130 kilometres northwest of Sudbury.
There were no injuries to the crew and no public safety concerns, Feigel said.
The westbound train was carrying a mix of consumer goods, he added.
The cause of the derailment has not been identified.
CP Rail crews were heading to the scene early Saturday afternoon to assess the situation.
