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.

Canada and the Digital Economy

The digital economy is the economic activity conducted through digital technologies such as the Internet. It is also called the Internet economy, the new economy or the web economy. Many scholars see the digital economy as the fourth industrial revolution. As of 2013, it consumed approximately 10 per cent of the world’s electricity. Many of the world’s biggest companies operate in the digital economy. A growing number of Canadians depend on it for their livelihood. In 2017, nearly 5 per cent of all jobs in Canada were in the digital economy. The gross domestic product (GDP) connected to it represented 5.5 per cent of Canada’s total economy — a bigger percentage than mining or oil and gas extraction. However, the often-hidden infrastructure of the digital economy brings new threats to the environment. The rise of cryptocurrencies could also dramatically change how people buy and sell things.
