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.

Aluminum in Canada

Aluminum is a lightweight, strong and flexible metal that resists corrosion and is 100 per cent recyclable. It is a common material in vehicles, buildings, consumer goods, packaging, power transmission and electronics. Canada’s aluminum industry began at the turn of the 20th century and grew quickly during both World Wars. Today, Canada is the world’s fourth largest producer and second largest exporter of aluminum. The country nevertheless accounts for less than 5 per cent of global production. Aside from one smelter in Kitimat, British Columbia, all Canadian plants are in the province of Quebec.

Health of Indigenous Peoples in Canada

Prior to colonization, Indigenous peoples possessed rich and diverse healing systems. Settlers’ introduction of new and contagious diseases placed these healing systems under considerable strain. Europeans also brought profound social, economic and political changes to the well-being of Indigenous communities. These changes continue to affect the health of Indigenous peoples in Canada today.

Childbirth in Canada

Childbirth is the beginning of a child’s life and a powerful rite of passage for the mother. Methods vary according to culture and time periods. Before the 19th century, Canadians relied mostly on the help of midwives, as well as prayers and even superstitions, to face the intense pains of contractions. Advances in the field of obstetrics in the 19th and 20th centuries introduced new ways of shortening the length of childbirth and managing its pains. Those developments also resulted in the transition of childbirth from homes to hospitals. Today, the different methods of childbirth can involve the help of physicians, midwives and doulas.

Post-Traumatic Stress Disorder (PTSD) in Canada

Post-traumatic stress disorder (PTSD) is a mental illness that affects individuals exposed to trauma (although not all people exposed to trauma develop PTSD). Studies suggest that over 70 per cent of Canadians have been exposed to at least one traumatic event in their lifetime, and that nearly 1 out of 10 Canadians may develop PTSD at some point in their lives. PTSD can affect adults and children and can appear months or even years after exposure to the trauma.

Eugenics in Canada

Eugenics is a set of beliefs and practices aimed at improving the human population through controlled breeding. It includes “negative” eugenics (discouraging or limiting the procreation of people considered to have undesirable characteristics and genes) and “positive” eugenics (encouraging the procreation of people considered to have desirable characteristics and genes). Many Canadians supported eugenic policies in the early 20th century, including some medical professionals, politicians and feminists. Both Alberta (1928) and British Columbia (1933) passed Sexual Sterilization Acts, which were not repealed until the 1970s. Although often considered a pseudoscience and a thing of the past, eugenic methods have continued into the 21st century, including the coerced sterilization of Indigenous women and what some have termed the “new eugenics” — genetic editing and the screening of fetuses for disabilities.
