Health Canada Warns of Dangers Linked to E-Cigarettes

Health Canada issued a second warning about the potential dangers of vaping e-cigarettes after two people died in the United States. Hundreds of others have contracted lung disorders. Dr. Nicholas Chadi, a spokesperson for the Canadian Paediatrics Society, said “We’re getting a strong message from the US that we need to be careful about vaping devices and aerosols that come from those devices. We’re still looking for answers, we don’t really know what might be causing these people to get ill, but we do know there are known harms associated with using electronic cigarettes.”

Study Finds Dangerous Lead Levels in Canadian Drinking Water

A year-long investigation conducted by 120 journalists representing nine universities and 10 media outlets, including the Toronto Star and the Institute for Investigative Journalism, found that one-third of 12,000 tests in 11 Canadian cities since 2014 registered lead levels in excess of the national safety guideline of five parts per billion. Voluntary tests were also conducted by homeowners in 32 towns and cities across Canada, with similar results.

Study Warns of Antibiotic-Resistant Superbugs

A study conducted by the Council of Canadian Academies concluded that the number of bacterial infections that are resistant to treatment will likely grow from 26 per cent in 2018 to 40 percent by 2050. The report estimates that, over the next 30 years, around 400,000 people will die from these superbugs at a cost to the economy of about $400 billion. The chair of the panel that produced the report, UBC microbiology professor Brett Finlay, said, “This is almost as big, if not bigger, than climate change in a sense because this is directly impacting people. The numbers are just staggering. It’s time to do something now.”

Vaccination and Vaccine Hesitancy 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.

15 Cases Reported in Vancouver Measles Outbreak

Two more measles cases were confirmed to have originated at two francophone public schools in Vancouver, bringing the total in that cluster to 12. An additional three cases were reported to have been contracted in Asia. BC Health Minister Adrian Dix said that children at public and private schools would be required to show proof of immunization against measles and other diseases beginning in September. Immunization rates at Vancouver public schools were shown to be well below the 90 per cent rate needed to ensure “herd immunity.” (See also Vaccination Rates are Plummeting.)

Food Insecurity in Canada

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.

Pandemics in Canada

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.

First Nation Issues State of Emergency After Evacuation Request Denied

The Neskantaga First Nation, located about 450 km north of Thunder Bay, issued a state of emergency after its request for emergency evacuations was refused by Indigenous Services Canada. The request was made after the town’s water pump and backup water pump broke down, resulting in contaminated and unfiltered water. A spokesperson for Indigenous Services said that technicians would arrive within days to repair the pumps. The Neskantaga reserve has been under a boil water advisory since 1995.

Maude Abbott

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).

SARS in Canada

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.

Ottawa Releases Long-Awaited Arctic Development Policy

After extensive consultations with First Nations and territorial governments, the federal government released its policy on developing the Canadian Arctic. It had been in the works since 2017. Eight priorities were identified, with health, infrastructure and economic development leading the way. However, many criticized the policy for not including specifics on how it would be implemented. International law professor and Arctic expert Michael Byers said, “In terms of an actual plan, there’s very little here.”

H1N1 Flu of 2009 in Canada

From April to December 2009, Canada experienced an outbreak of influenza A (H1N1). The virus began in North America and spread to many other countries in a global pandemic. This new type of flu differed from the typical seasonal flu, and its effects were more severe. Worldwide, more than 18,000 people are confirmed to have died of H1N1, including 428 Canadians. Estimates based on statistical models have put global deaths much higher. Totals may have been in the hundreds of thousands. The H1N1 pandemic tested Canada’s improvements to its public health system after the SARS outbreak of 2003. On the whole, it revealed a more efficient, coordinated response.

Quarantine Act

Canada adopted quarantine legislation in 1872, five years after Confederation. It was replaced by the current Quarantine Act, which was passed by the Parliament of Canada and received royal assent in 2005. The act gives sweeping powers to the federal health minister to prevent the introduction and spread of communicable diseases. These powers can include health screenings, the creation of quarantine facilities and mandatory isolation orders. The Quarantine Act was introduced in the wake of the severe acute respiratory syndrome (SARS) crisis of 2003. It was invoked in March 2020 in response to the COVID-19 pandemic.

Canada's Opioid Crisis

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.

Food Insecurity in Nunavut Worsened After Government Subsidy Program, Research Finds

A study conducted at the Department of Nutritional Sciences at the University of Toronto and published in the Canadian Medical Association Journal found that rates of food insecurity in Nunavut’s 10 largest communities have risen 13 per cent since federal subsidies designed to make food more affordable were introduced in 2011. Andrée-Anne Fafard St-Germain, the lead researcher in the study, called for an inquiry “to determine the extent to which similar initiatives adapted to the needs and realities of northern populations could affect food insecurity.”
