Inside the oil-shipping free-for-all that brought disaster to Lac-Mégantic

Long before disaster struck, the 5,900 residents of Lac-Mégantic had grown accustomed to the sight of large oil tankers rolling through their small, tightly knit community in the Eastern Townships of Quebec. A shortage of oil pipelines in North America had created a new kind of railway industry traversing the continent. In just a few years, tankers carrying crude oil from the resource-rich West had grown from a mere 8,000 in 2009 to nearly 400,000, and Lac-Mégantic is located along one of the main routes to refineries in the East.
