Endangered Plants in Canada

A species is endangered if there are threats to its survival. Plants are put at risk for several reasons, including: climate change and the loss of natural habitat to cities, agriculture and industry. In Canada, these activities threaten entire natural ecosystems, such as older forests and Prairie grasslands. As of 2021, 250 plant species are at risk in Canada, according to the Committee on the Status of Endangered Wildlife in Canada. In addition, four are extirpated and one is extinct. The committee’s definition of a wildlife species includes taxonomic categories as well as geographically distinct populations. For example, the bent spike-rush (Eleocharis geniculate) is included on the list of at risk plant species twice, as there are two different populations, one in British Columbia and one in Ontario, facing different threats to their survival.

Royal Newfoundland Regiment

The Newfoundland Regiment was established in September 1914 and served overseas during the First World War. It was redesignated the Royal Newfoundland Regiment in 1918. The regiment served in the Gallipoli (or Dardanelles) campaign, and in France and Belgium. It suffered heavy casualties during the Battle of Beaumont-Hamel on 1 July 1916; more than 80 per cent of the regiment was either killed or wounded. The regiment was disbanded in 1919. In 1949, after Newfoundland entered into confederation with Canada, the Newfoundland Regiment was re-established as a Royal Canadian Infantry Corps reserve regiment.


Peasant Farm Policy

From 1889 to 1897, the Canadian government’s Peasant Farm Policy set limits on Indigenous agriculture on the Prairies. The policy included rules about the types of tools First Nations farmers could use on reserve lands. It also restricted how much they grew and what they could sell. The Peasant Farm Policy was built on the belief that Indigenous farmers had to gradually evolve into modern farmers. It also reduced these farmers’ ability to compete with settlers on the open market. The policy ultimately impeded the growth and development of First Nations farms. As a result, First Nations never realized their agricultural potential.


Leatherback Sea Turtle

The leatherback sea turtle (Dermochelys coriacea), or simply “leatherback,” is the largest turtle and widest-ranging reptile in the world. It began evolving over 100 million years ago and is the last remaining member of the Dermochelyidae family. It has seven subpopulations worldwide, two of which can be found in Canadian waters.


Alberta Clipper

An Alberta Clipper is a type of low-pressure weather system that forms in Alberta or nearby, on the eastern side of the Rocky Mountains. It is a fast-moving storm, hence the name “clipper,” which refers to 19th-century ships known for their speed. Depending on the province where the system approaches the Canada-United States border, sometimes it is called a Saskatchewan Screamer, Manitoba Mauler or Ontario Scary-o. It may also be called a Canadian Clipper or simply a Clipper. Such storms mostly occur in December and January but are common in the fall and spring, too. They form about 5–20 times per season.


Right Whale

Right whales are a baleen whale found in the Atlantic, Pacific, and Indian Oceans. There are three species: the North Pacific right whale (Eubalaena japonica), North Atlantic right whale (Eubalaena glacialis) and southern right whale (Eubalaena australis). In Canadian waters, the North Pacific right whale is rarely sighted, but was historically found along British Columbia’s coast. The North Atlantic right whale is found along the Scotian Shelf and in the Gulf of St. Lawrence. Both the North Pacific and North Atlantic right whale are listed as endangered under Canada’s Species at Risk Act. (See also Endangered Animals in Canada.)


Blue Box

The blue box is a plastic bin used in curbside recycling programs. The bins are filled with materials — including paper, glass, cans and select plastics — which are then collected by waste management professionals. Resource Integration Systems, the sister organization of a countercultural non-profit, and Superior Sanitation pioneered the blue box system in Kitchener, Ontario, in 1981. By 1986, the program began to operate province-wide. Today, blue boxes continue to be used in Ontario, home to one of the world’s most comprehensive recycling programs. Blue boxes are also used in municipal recycling programs in British Columbia, Alberta, Saskatchewan, Manitoba and Quebec.


The Pig War

The “Pig War” of 1859 was a confrontation between the United States and Great Britain over the location of the international border in the San Juan Islands. The conflict began when an American settler killed a pig owned by an employee of the Hudson’s Bay Company; it quickly grew to involve British warships and hundreds of troops on both sides. The root of the conflict was an earlier compromise between the two nations that resulted in American and British settlers sharing the disputed islands. Though called a war, it never actually degenerated into an armed conflict, and there were no human casualties. In late 1859, the two sides agreed to a joint military occupation of the islands; this lasted until 1872, when the San Juan Islands became part of US territory.


Climate Change (Plain-Language Summary)

Climate change happens when weather patterns change. This has happened a lot in the past and will continue to happen. It is a normal phenomenon. For example, the last cold period peaked approximately 18,000 years ago. This era is known as the Ice Age. After that, Earth’s climate began to warm again. Since the Industrial Revolution climate change has been happening very quickly. This period is known as “global warming.” There is one big difference between this period and the other periods of climate change that came before. The difference is that human beings have caused global warming.

North-West Resistance (Plain-Language Summary)

The North-West Resistance happened between March 1885 until May 1885. The resistance took place in what is now Alberta and Saskatchewan. It was fought between the Métis and First Nations allies against settlers and the federal government. The government won. Hundreds died. The Indigenous peoples lost everything. The leader of the Métis, Louis Riel, was executed. This caused a serious controversy. It is still a controversial issue. The events of 1885 have left a legacy.

Agriculture in Canada

Agriculture is the practice of growing crops and rearing animals mainly for food. Farmers also produce other items such as wool from sheep and CBD oil from hemp plants.

In Canada, agriculture is an important industry. Only about 7 per cent of Canada’s land can be farmed. Other marginal (poorer) land can be used to ranch cattle. Aquaculture operations are found on the East and West Coasts and in the Great Lakes. Some crops such as tomatoes, cannabis and flowers are grown in greenhouses in urban centres. Canadian agriculture faces many challenges. Some of these challenges concern crop protection, soil conservation, labour, climate change and health.

Substances used to control pests include insecticides (for control of insects), fungicides (for disease-causing fungi), herbicides (for weeds), rodenticides (for rodents), avicides (for birds), piscicides (for fish) and nematicides (for nematodes).





Archaeological Survey of Canada

The Archaeological Survey of Canada (ASC) was established in 1971. It is the division of the Canadian Museum of History that deals with the archaeological heritage of Canada. The major goals of the ASC are to preserve archaeological sites, research into the history of Canadian Indigenous peoples and present the results of archaeological research to the public, through publications and exhibitions. The ASC’s Mercury Series of monographs is one of the main outlets for the reporting of archaeological research in the country. Its exhibitions, both in the Canadian Museum of History and smaller ones that travel across the country, enhance public understanding of the traditions of the Indigenous peoples of Canada.

Traditional tales about the Loup-Garou are found in French Canadian and European folklore. The Loup-Garou is also called lycanthrope or werewolf. A Loup-Garou is generally believed to a person who can change into animal form, often as a wolf. In French Canadian folklore, the Loup-Garou is often a dog. It may also take the form of a calf or small ox, a pig, a cat or even an owl.
