Lac-Mégantic Rail Disaster

In the early morning of 6 July 2013, a runaway train hauling 72 tankers filled with crude oil derailed as it approached the centre of the town of Lac-Mégantic, Quebec.

Canada and the Development of the Polio Vaccine

During the first half of the 20th century, poliomyelitis, a.k.a. polio or “The Crippler,” hit Canada harder than anywhere else. Successive polio epidemics peaked in a national crisis in 1953. By that time, however, scientists at Connaught Medical Research Laboratories of the University of Toronto had made key discoveries that enabled American medical researcher and virologist Jonas Salk to prepare the first polio vaccine. Connaught Labs also solved the problem of producing the vaccine on a large scale. Canada went on to play an important role in the development of the oral polio vaccine and international efforts to eradicate the disease.
