American Civil War and Canada

The American Civil War (1861–65) was fought between the northern (Union) states and the southern (Confederate) states, which withdrew from the United States in 1860–61. The war left cities in ruins, shattered families and took the lives of an estimated 750,000 Americans. The war also involved those living in what is now Canada, including roughly 40,000 who joined the fight. The war played a significant role in how and when Canada became an independent country.

Canada’s Cold War Purge of LGBTQ from Public Service

Between the 1950s and the 1990s, the Canadian government responded to national security concerns generated by Cold War tensions with the Soviet Union by spying on, exposing and removing suspected LGBTQ individuals from the federal public service and the Canadian Armed Forces. They were cast as social and political subversives and seen as targets for blackmail by communist regimes seeking classified information. These characterizations were justified by arguments that people who engaged in same-sex relations suffered from a “character weakness” and had something to hide because their sexuality was considered a taboo and, under certain circumstances, was illegal. As a result, the RCMP investigated large numbers of people. Many of them were fired, demoted or forced to resign — even if they had no access to security information. These measures were kept out of public view to prevent scandal and to keep counter-espionage operations under wraps. In 2017, the federal government issued an official apology for its discriminatory actions and policies, along with a $145-million compensation package.

Manifest Destiny

The term Manifest Destiny was first used in 1845 by New York City journalist John Louis O’Sullivan. He used the term in the context of America’s annexation of the Republic of Texas. Manifest Destiny represented the idea that it was America’s right — its destiny, in fact — to expand across all of North America. Politicians and citizens in the United States called for the US to expand by claiming control of British territory. This included the Province of Canada (formerly Upper Canada and Lower Canada), New Brunswick and Nova Scotia.

Korean War

The Korean War began 25 June 1950, when North Korean armed forces invaded South Korea. The war’s combat phase lasted until an armistice was signed 27 July 1953. As part of a United Nations (UN) force consisting of 16 countries, 26,791 Canadian military personnel served in the Korean War, during both the combat phase and as peacekeepers afterward. The last Canadian soldiers left Korea in 1957. After the two world wars, Korea remains Canada’s third-bloodiest overseas conflict, taking the lives of 516 Canadians and wounding more than 1,200. The two Koreas remain technically at war today.

Fake News (a.k.a. Disinformation) in Canada

Fake news is falsified information created with the intent of misleading people. It aims to shape public opinion by eliciting an emotional and biased response that is divorced from facts but in alignment with a particular ideology or perspective. Fake news can effectively weaponize information. It uses disinformation, misinformation or mal-information to demonize or damage a political foe, or to sow confusion and mistrust among the public. Fake news came to the fore of public consciousness during and immediately after the 2016 US presidential election, though its origins date back much further.

War of 1812

The War of 1812 (which lasted from 1812 to 1814) was a military conflict between the United States and Great Britain. As a colony of Great Britain, Canada was swept up in the War of 1812 and was invaded several times by the Americans. The war was fought in Upper Canada, Lower Canada, on the Great Lakes and the Atlantic, and in the United States. The peace treaty of Ghent (1814), which ended the war, largely returned the status quo. However, in Canada, the war contributed to a growing sense of national identity, including the idea that civilian soldiers were largely responsible for repelling the American invaders. In contrast, the First Nations allies of the British and Canadian cause suffered much because of the war; not only had they lost many warriors (including the great Tecumseh), they also lost any hope of halting American expansion in the west, and their contributions were quickly forgotten by their British and Canadian allies (see First Nations and Métis Peoples in the War of 1812).

Avro Arrow

The Avro Canada CF-105 Arrow (the Arrow) was a supersonic interceptor jet aircraft designed and built in the 1950s by A.V. Roe Canada (Avro). The Arrow was one of the most advanced aircraft of its era, helping to establish Canada as a world leader in scientific research and development.

Though the Arrow was widely praised for its power and beauty, the program was cancelled in February 1959 by the government of Prime Minister John Diefenbaker. This resulted in the loss of at least 25,000 direct and indirect jobs.

Many believe that the Arrow’s cancellation was a betrayal of Canada’s aerospace industry. Others assert that the jet was extravagant and had little chance of competing with impending innovations. At best, Avro and the Arrow were historic examples of Canadian ingenuity and intriguing case studies of unrealized potential.

Seven Years’ War (Plain-Language Summary)

The Seven Years’ War (1756–63) was the first global war. In North America, Britain and France fought each other with the help of Indigenous allies. At the end of the war, France gave Canada (Quebec) and Ile Royale (Cape Breton) to Britain, among other territories.

Antibiotic Resistance in Canada

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.

Battle of Queenston Heights

The Battle of Queenston Heights was fought during the War of 1812 on 13 October 1812. One of the most famous battles of the war, the Battle of Queenston Heights was the struggle for a portion of the Niagara escarpment overlooking Queenston, where more than 1,000 American soldiers crossed into Upper Canada. Part of the American force reached the top, circled the British artillery position and forced the British from the Heights. General Isaac Brock, one of the most respected British military leaders of his day, was killed leading a counter-attack. Mohawk chiefs John Norton and John Brant and about 80 Haudenosaunee and Delaware warriors held back the Americans for hours — long enough for reinforcements to arrive so that the British could retain the crucial outpost.

Fenians

Fenians were members of a mid-19th century movement to secure Ireland’s independence from Britain. They were a secret, outlawed organization in the British Empire, where they were known as the Irish Republican Brotherhood. They operated freely and openly in the United States as the Fenian Brotherhood. Eventually, both wings became known as the Fenians. They launched a series of armed raids into Canadian territory between 1866 and 1871. The movement was primarily based in the United States, but it had a significant presence in Canada.
