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.

Natural Gas in Canada

Natural gas ranks among the fastest-growing energy sources in Canada and is seen by many in the energy industry as a game-changer, a comparatively clean, low-cost and versatile fuel. It can directly generate power and heat and can be chemically altered to produce a wide range of useful commodity chemicals. It burns cleaner and more efficiently than other fossil fuels, releasing significantly fewer harmful pollutants into the atmosphere. Natural gas is colorless, odourless, shapeless, lighter than air and contains a mixture of several hydrocarbon gases, which are organic compounds consisting of some combination of hydrogen and carbon molecules.

The primary consumers of natural gas are the industrial (54.1 per cent), residential (26.6 per cent) and commercial sectors (19.3 per cent). Canada is the fifth largest natural gas producer after the United States, Russia, Iran and Qatar. Currently, all of Canada’s natural gas exports go to the United States through a network of pipelines, making Canada the largest foreign source of US natural gas imports. At the end of 2016, Canada had 76.7 trillion cubic feet of proven natural gas reserves and had produced 152 billion cubic metres of natural gas that year. It is forecasted that global natural gas consumption will double by 2035.

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. The tanker cars exploded and the oil caught fire, killing 47 people and destroying many buildings and other infrastructure in the town centre. The fourth deadliest railway disaster in Canadian history, the derailment led to changes in rail transport safety rules as well as legal action against the company and employees involved in the incident. Years after the derailment, re-building was still ongoing and many of the town’s residents continued to suffer from post-traumatic stress.

Invention of Standard Time
