TORONTO (Reuters) - Seven rail cars were on fire in northern Ontario after a train carrying crude oil derailed late on Saturday night, Canadian National Railway said on Sunday.

The train, heading from Alberta to eastern Canada, derailed shortly before midnight about 80 km (50 miles) south of Timmins, Ontario, a CN spokesman said. Canada's largest rail operator said 29 of 100 cars were involved and seven were on fire.
