According to CN, 14 rail cars went off the tracks just before 5:00 p.m. on Friday evening near Barwick, Ontario, about 45 km west of Fort Frances.

CN says one of the derailed cars carrying a combustible liquid leaked some of that product, but the company says the leak was stopped and contained and crews are working to clean up the spill.

CN did not identify the combustible liquid but Chapel Hill Reeve Peter Van Heyst told CTV News it was a petroleum product.

About 100 people were forced from their homes under orders from Ontario Provincial Police.

CN called the move precautionary and says local emergency officials have since lifted the evacuation order.

According to Heyst, people were allowed to return to their homes around 11:00 a.m. Saturday.

Of the 14 cars that went off the tracks, some were carrying grain and others a combustible liquid that CN did not identify.

CN says the cause of the derailment remains under investigation.
