TORONTO - Canada will take older tank cars out of crude-by-rail service months earlier than originally planned, the government said on Monday, its latest move to toughen rail safety in the wake of a deadly 2013 crash.

Some of the older tankers, called DOT-111 cars, had been scheduled to go out of service on May 1, 2017, with a jacketed version of the older cars set to phase out March 1, 2018. Both types of cars will now be taken out of service by Nov. 1, 2016, a spokeswoman from the federal transport minister's office said.

Transport Minister Marc Garneau is set to announce the change on Monday.

Accident investigators have said the cars tend to puncture during derailments, sometimes causing fires. The runaway train that derailed and exploded, leveling part of the Quebec town of Lac-Megantic and killing 47 people in 2013 was made up of DOT-111 tank cars.

The change moves Canada's retrofit schedule further ahead of the United States, limiting the number of cars that can be used on cross-border routes.

"All rail tank cars transporting flammable liquids entering Canada, whether in transit or as a final destination, must meet the Canadian phase-out schedule," the minister's office said in a statement.

Under a regulation finalized in May 2015, the United States would let DOT-111 cars carry oil in the more dangerous packing group I classification until January or March 2018. It would let crude in the less dangerous packing group II travel in DOT-111 cars as late as May 2023.
