Closing arguments are underway in Quebec Monday at the jury trial of three men charged with criminal negligence in the Lac-Mégantic rail disaster that killed 47 people.
The proceedings in Sherbrooke are set to last three days.
On July 6, 2013, a runaway train carrying crude oil from the United States derailed in Lac-Megantic and exploded, killing the 47 and destroying part of the downtown core.
The Crown argued the locomotive weighing more than 10,000 tonnes was not properly secured, leaving it resting precariously on a slope 10 kilometres away from Lac-Mégantic.
