Spectroscopy is the field of study that examines, measures and interprets the electromagnetic spectra produced when radiant energy is emitted or absorbed by a substance. Spectroscopic methods are important in performing chemical analyses of substances and are used in astronomical studies.

Wendake is a Huron-Wendat settlement dating back to the 17th century, once known by various names including “Huronia,” "the country of the Huron" or “the Huron village.” Today, Wendake refers to the urban reserve of the Huron-Wendat Nation, located near Quebec City, Quebec.

In the summer of 1859, Superintendent General of the Indian Department Richard T. Pennefather signed three separate but essentially identical treaties with Batchewana First Nation (Treaty 91 [A]), Garden River First Nation (Treaty 91 [B]) and Thessalon First Nation (Treaty 91 [C]). The three treaties were part of a series of land surrenders that occurred after the 1850 Robinson Treaties. The Pennefather treaties opened additional acres for settlement and resource exploitation. (See also Treaties with Indigenous Peoples in Canada.)

The Internet is a global network of computers that communicate with each other. This exchange happens through a set of rules called protocols. Since Internet use became widespread in the 1990s, the system has affected most aspects of life. It has had both productive and destructive effects. The Internet has changed the way Canadians learn and work, buy products and services, communicate and consume entertainment. Most people think of the Internet as the World Wide Web. However, it takes a number of different forms, including networked physical objects called the Internet of Things.

One of the most acclaimed Canadian TV series of all time, Schitt’s Creek is a CBC sitcom about a wealthy family who loses their fortune and is forced to live in the fictional small town of the show’s name. Created by co-stars Daniel Levy and his father, Eugene Levy, the series is centred on the tension between the town’s down-to-earth residents and the ostentatious Rose family. In 2020, it won nine Primetime Emmy Awards and became the first comedy series ever to win all seven of the top awards: best comedy series, best lead and supporting actor and actress, and best writing and directing. It has also won two Golden Globes and 24 Canadian Screen Awards, including five for best actress in a comedy series (Catherine O’Hara) and three for best comedy series.

The origins of ice hockey have long been debated. In 2008, the International Ice Hockey Federation (IIHF) officially declared that the first game of organized ice hockey was played in Montreal in 1875. Many also consider ice hockey’s first rules to have been published by the Montreal Gazette in 1877. However, research reveals that organized ice hockey/bandy games were first played on skates in England and that the earliest rules were also published in England. Canada made important contributions to the game from the 1870s on. By the early 20th century, “Canadian rules” had reshaped the sport.

The Quiet Revolution (1960–1970) gave rise to secularism within Quebec society. The latter became both secular by widening the separation between Church and State, as well as non-confessional by removing religion from institutions. 

However, the issue of secularism is still a matter for debate. In June 2019, the passage of the Act Respecting the Laicity of the State fueled many discussions about the place of religion in public domain.

Fatty Legs (2010) is a memoir about a young Inuvialuit girl’s two years at a religious residential school. It is based on the experiences of Margaret Pokiak-Fenton, who cowrote the novel with her daughter-in-law Christy Jordan-Fenton. Published by Annick Press, the book features illustrations by Liz Amini-Holmes and archival photographs from Pokiak-Fenton’s personal collection. Fatty Legs was a finalist for the Sheila A. Egoff Children’s Literature Prize. It received many other nominations and was named one of the 10 best children’s books of the year by the Globe and Mail.

The North American Aerospace Defense Command (NORAD) was a pact made in 1957, at the height of the Cold War. It placed under joint command the air forces of Canada and the United States. Its name was later changed to the North American Aerospace Defense Command; but it kept the NORAD acronym. Canada and the US renewed NORAD in 2006, making the arrangement permanent. It is subject to review every four years, or at the request of either country. NORAD’s mission was also expanded into maritime warnings. The naval forces of the two countries remain under separate commands.

The teaching profession, broadly defined, includes all those offering instruction in public or private institutions or independently.

The first Treaty of Fort Stanwix was signed in 1768 between the Haudenosaunee (also known as the Six Nations or Iroquois Confederacy) and British Superintendent of Indian Affairs in the Northern District, Sir William Johnson. It was the first major treaty to be negotiated according to the Royal Proclamation of 1763. Five years after the proclamation had set the western boundary of colonial settlement at the Appalachian Mountains — reserving the vast North American interior as Indigenous territory — the Treaty of Fort Stanwix pushed the border west to the Ohio River, opening up lands to white settlers. The second Treaty of Fort Stanwix, signed in 1784, was an agreement between the Haudenosaunee and the newly independent United States. This treaty redrew the eastern boundaries of the first Treaty of Fort Stanwix, surrendering more Indigenous territory.

Bison are large, even-toed hoofed mammals of the family Bovidae. Two subspecies of bison exist in North America: the plains bison (Bison bison bison) and the wood bison (Bison bison athabascae). Historically, the plains bison lived primarily in the Great Plains of central North America, while the wood bison lived further north, from Alaska into the Yukon and the Northwest Territories, and in the northern portions of British Columbia, Alberta and Saskatchewan. Prior to the arrival of Europeans, it’s estimated that plains bison numbered 30 million and wood bison 170,000. Various aspects of European colonization led to the rapid depopulation of North America’s bison. By the late 1800s, plains bison no longer existed in Canada, and wood bison numbered about 200. Conservation efforts in both Canada and the United States mean that today, North America’s plains bison population fluctuates between 350,000 and 400,000, and wood bison between 5,000 and 7,000.

Propaganda refers to messaging that aims to spread or “propagate” an ideology or worldview. Psychologists have described propaganda as “manipulative persuasion in the service of an agenda” or communications that “induce the individual to follow non-rational emotional drives.” During the First World War, propaganda was used to recruit soldiers and supporters. The Second World War saw it take a dark turn toward using outright lies to spread hateful ideologies and practices. (See also Fake News a.k.a. Disinformation.) During the Cold War, governments in the West and East used propaganda to try to spread the ideologies of capitalism and democracy, or communism and the Soviet Union. Today, propaganda is most often found on social media; it is used to marshal support for, or opposition to, various political, economic and social movements.

In April 1935, about 1,500 residents of federal Unemployment Relief Camps in British Columbia went on strike. They travelled by train and truck to Vancouver to protest poor conditions in the Depression-era camps. After their months-long protest proved futile, they decided to take their fight to Ottawa. On 3 June, more than 1,000 strikers began travelling across the country, riding atop railcars. By the time they reached Regina, they were 2,000 strong. But they were stopped in Regina, where the strike leaders were arrested, resulting in the violent Regina Riot on 1 July 1935.

The Senate is the Upper House of Canada’s Parliament. Its 105 members are appointed and hold their seats until age 75. The Senate’s purpose is to consider and revise legislation; investigate national issues; and most crucially according to the Constitution, give the regions of Canada an equal voice in Parliament. The Senate is a controversial institution. It has long been regarded by many Canadians as a place of unfair patronage and privilege. An unresolved debate continues about whether it should be reformed into an elected body accountable to the voters, or abolished.

Taxes are mandatory payments by individuals and corporations to government. They are levied to finance government services, redistribute income, and influence the behaviour of consumers and investors. The Constitution Act, 1867 gave Parliament unlimited taxing powers and restricted those of the provinces to mainly direct taxation (taxes on income and property, rather than on activities such as trade). Personal income tax and corporate taxes were introduced in 1917 to help finance the First World War. The Canadian tax structure changed profoundly during the Second World War. By 1946, direct taxes accounted for more than 56 per cent of federal revenue. The federal government introduced a series of tax reforms between 1987 and 1991; this included the introduction of the Goods and Services Tax (GST). In 2009, the federal, provincial and municipal governments collected $585.8 billion in total tax revenues.

Exercise Tocsin B was a nationwide nuclear preparedness drill that lasted 24 hours between 13 and 14 November 1961. It was the last of three national survival exercises named Tocsin in 1960–61. It was also the largest and most widely publicized civil defence drill ever held in Canada. This Cold War exercise run by the Canadian Army simulated the impact of thermonuclear warfare in Canada. Its goals were to show how the state would warn Canadians of such an attack and how government would continue during the crisis. By raising popular awareness of the potential for a devastating nuclear attack, Tocsin B showed Canadians what was at stake in the Cold War.

The National Aboriginal Veterans Monument was unveiled in 2001 in Ottawa to commemorate the contributions made by Indigenous peoples in Canada during the First World War, Second World War and Korean War. The monument, a bronze statue with a granite base, was created by Indigenous artist Noel Lloyd Pinay of the Peepeekisis First Nation in Saskatchewan. It is situated in Confederation Park, directly across from the Lord Elgin Hotel. It is the first monument dedicated to Indigenous veterans in Canada.

The Compagnie des Indes occidentales was a trading company that drove France’s colonial economy from 1664 to 1674. Its name translates to West Indies Company. King Louis XIV gave the company exclusive rights to trade and govern in all French colonies. Its territory extended from the Americas to the Caribbean and Western Africa. In addition to natural resources such as furs and sugar, the Compagnie traded enslaved people.

This company is not to be confused with the French trading company founded by John Law and renamed Compagnie des Indes in 1719.

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.)
