The
Lac-Mégantic rail disaster occurred in the town of Lac-Mégantic, Quebec, Canada, on July 6, 2013, at approximately 1:14 a.m. EDT, when an unattended 73-car Montreal, Maine and Atlantic Railway (MMA) freight train carrying Bakken Formation crude oil rolled down a 1.2% grade from Nantes and derailed downtown, resulting in the explosion and fire of multiple tank cars. Forty-seven people were killed. More than thirty buildings in Lac-Mégantic's town centre (roughly half of the downtown area) were destroyed, and all but three of the thirty-nine remaining buildings had to be demolished due to petroleum contamination. Initial newspaper reports described a 1 km (0.6-mile) blast radius.
The Transportation Safety Board of Canada identified multiple causes for the accident, principally leaving a train unattended on a main line, failure to set enough handbrakes, and lack of a backup safety mechanism.
The death toll of 47 makes this the fourth-deadliest rail accident in Canadian history, and the deadliest involving a non-passenger train. It is also the deadliest rail accident since Canada's confederation in 1867. The last Canadian rail accident to have a higher death toll was the St-Hilaire train disaster in 1864, which killed 99.

The Transportation Safety Board of Canada (TSB) launched an investigation into the accident. In its August 2014 report, the TSB identified 18 distinct causes and contributing factors, which included leaving the train unattended on a main line, failure to set enough hand brakes, the lack of a backup safety mechanism, poor maintenance on the locomotive and several failures of training and oversight.
