Maude Elizabeth Seymour Abbott, cardiac pathologist, physician, curator (born 18 March 1868 in St. Andrews East, QC; died 2 September 1940 in Montreal, QC). Maude Abbott is known as the author of The Atlas of Congenital Cardiac Disease (1936), a groundbreaking text in cardiac research. Though Abbott graduated in arts from McGill University (1890), she was barred from studying medicine at McGill because of her gender. Instead, she attended Bishop’s College (now Bishop’s University), earning a medical degree in 1894. As assistant curator of the McGill Medical Museum (1898), and curator (1901), she revolutionized the teaching of pathology by using the museum as an instructional tool. Abbott’s work paved the way for women in medicine and laid the foundation for modern heart surgery. (See also Women in STEM).

Birth control means the deliberate prevention of conception and pregnancy. The birth control methods used in Canada range from the simplest (like abstinence) to the most complex (like male or female surgical sterilization). (See also History of Birth Control in Canada.)

Vaccination is the introduction of a vaccine into the body to produce immunity to a disease. Vaccine hesitancy is the refusal or delayed acceptance of vaccination due to fears or anxiety about vaccines. It includes a range of concerns such as uncertainty about vaccines’ contents and their safety and the belief that vaccines are responsible for causing other medical conditions (e.g., autism). Other factors include opposition to state control and infringement on individual liberty, suspicions about the pharmaceutical industry and a declining faith in science and medicine. In Canada, as in other wealthy countries, vaccine hesitancy has increased in recent years.

Canada experienced an outbreak of severe acute respiratory syndrome (SARS) in 2003. Most of the infections originated in Toronto hospitals. The outbreak led to the quarantine of thousands, killed 44 people and took an economic toll on Toronto. It also exposed the country’s ill-prepared health-care system. Confusion around SARS fuelled an uptick in anti-Asian and anti-immigrant sentiment.

Antibiotic (or antimicrobial) resistance developed with the wide distribution of antibiotic medications in the 20th century. Resistance occurs when the medication is no longer capable of killing or preventing the reproduction of bacteria. A major global health challenge, antibiotic resistance makes treating diseases more difficult and expensive, and it results in fewer antibiotics that are effective in managing infectious diseases. Rates of antibiotic-resistant infections are rising in Canada. In hospital settings, infections that resist multiple drugs are also becoming more common. In 2019, an expert panel of the Council of Canadian Academies estimated that resistant infections contributed to more than 14,000 deaths in Canada the previous year. Canadian health agencies, medical professionals and industries are active in multiple efforts to combat this problem. 

Jean Cuthand Goodwill, OC, nurse, public servant and Indigenous health and education advocate (born 14 August 1928 on the Poundmaker Cree Nation, SK; died 25 August 1997 in Regina, SK). Cuthand Goodwill was one of the first Indigenous registered nurses in Canada. In 1974, she cofounded Indian and Inuit Nurses of Canada (now known as the Canadian Indigenous Nurses Association). She was a lifelong organizer, writer and educator who promoted First Nations health and culture.

Onyenyechukwu (Onye) Nnorom, family physician, specialist in public health and preventive medicine (born 27 February 1981 in Montreal, Quebec). Nnorom is the associate director of the residency program in public health and preventive medicine at the University of Toronto’s Dalla Lana School of Public Health. She also leads the Black health curriculum at the university’s medical school. Her work addresses the health inequities that racialized and immigrant communities face.

Human beings have practised birth control throughout history. However, in 19th-century Canada, this practice was largely forbidden or taboo. It was only in the 1920s that groups of citizens formed to defend birth control. The information, services and products related to this practice became increasingly accessible after the war. During the 1960s, Canada decriminalized contraception and abortion. In the 1970s, the number of organizations and services promoting access to contraception and family planning began to increase. From then on, birth control became an integral part of the public health approach to sexual health.

Overdoses from a class of painkiller drugs called opioids are claiming the lives of thousands of Canadians from all walks of life. The death count is the result of an escalating public health crisis: an epidemic of opioid addiction. The crisis is made deadlier by an influx of illicit fentanyl and chemically similar drugs, but it can be traced to the medical over-prescribing of opioids, including oxycodone, fentanyl and morphine.

Household food insecurity— the inadequate or insecure access to food due to financial constraints — is a serious public health problem in Canada. In 2017–18, 1 in 8 households were food insecure. This amounted to over 4.4 million Canadians. Of that number, 1.2 million were children under 18 years. While food banks are a well-known public response to food insecurity, most food insecure households do not use food banks and there is no evidence that food charity is a durable solution. There is wide consensus that governments need to act on food insecurity through income-based interventions.

The Duplessis orphans were a cohort of children placed, from 1935 to 1964, in nurseries, orphanages and psychiatric hospitals, where many of them were mistreated or abused. A significant number of these children were falsely diagnosed as being mentally defective, to enable the institutions housing them to receive subsidies allocated to psychiatric facilities. This practice primarily occurred under Premier Maurice Duplessis, whose name has therefore been used to designate these children. Following a number of years of legal battles and political pressure, most of the Duplessis orphans have obtained a measure of compensation from the Quebec state.

A pandemic is an outbreak of an infectious disease that affects a large proportion of the population in multiple countries or worldwide. Human populations have been affected by pandemics since ancient times. These include widespread outbreaks of plague, cholera, influenza and, more recently, HIV/AIDS, SARS and COVID-19. In order to slow or stop the spread of disease, governments implement public health measures that include testing, isolation and quarantine. In Canada, public health agencies at the federal, provincial and municipal levels play an important role in monitoring disease, advising governments and communicating to the public.
