How the world began is a question as old as the human race. It was not before the 20th century, however, that the evolution and large-scale structure of the universe emerged as a well-defined problem of interest to science.
COVID-19 is a severe acute respiratory syndrome caused by a new type of coronavirus, SARS-CoV-2, that emerged in 2019. The virus caused the first cases in China and then quickly spread around the world. As of early March 2022, the COVID-19 pandemic has caused more than 434 million confirmed cases and 5.9 million deaths globally, including over 3.2 million cases and 36,000 deaths in Canada. It is one of the deadliest pandemics in world history and among the most disruptive and transformative on many levels, especially economically and socially.
On 28 May 1980, 22 workers on a Canadian Pacific Railway steel crew were killed in a bus accident on the Trans-Canada Highway near Webb, Saskatchewan, west of Regina. It was one of the deadliest motor vehicle disasters in Canadian history.
Most of the criminological research in Canada has been done at those universities where centres focusing on research have evolved. The Université de Montréal established Canada's first School of Criminology with Denis Szabo in 1960.
Crop research may be defined as activity directed to making the production, marketing and use of commercial crops more efficient and profitable.
Crops are plant species grown for human or animal consumption or for special purposes (e.g., flax, tobacco). In Canada, most major crops grown are used for food and feed.
Cryptozoology is the scientific study of unknown animals about which only circumstantial, or at best insufficient, material evidence is available.
The Tracker was a twin-engine fixed-wing aircraft acquired by the Royal Canadian Navy (RCN) to be flown off aircraft carriers for antisubmarine warfare (ASW) as a replacement for the Grumman Avenger. Originally developed for the United States Navy (USN), a Canadian version was manufactured under licence by de Havilland Canada as the CS2F. After unification the plane was redesignated as the CP-121; the Trackers became shore-based aircraft after the aircraft carrier HMCS Bonaventure was decommissioned. The Trackers became fully operational in 1959 and were withdrawn from service in 1989.
CTrain is a light rail transit system in Calgary, Alberta. It is operated by Calgary Transit, a public transit service owned by the City of Calgary and operated through its Transportation Department. Service began on the initial downtown transit corridor and south line in 1981. It expanded to northeast Calgary in 1985, to the University of Calgary in the city’s northwest in 1987 and to the city’s west side in 2012. Most of its route and stations are at surface level. Calgary Transit operates the CTrain in conjunction with an extensive network of bus routes. Through equivalency purchases of wind-generated electricity, it has been entirely wind-powered since 2001. Its two separate lines comprise 45 stations, 118.1 km of track, and an average daily ridership of 312,300 (2018).
Cystic Fibrosis Canada is a national, nonprofit, voluntary health agency established 15 July 1960. Cystic fibrosis is a disorder that occurs when a child inherits 2 genes for the condition, one from each parent.
For those researchers working in the field of human history, the chronology of events remains a major element of reflection. Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.
The Dawson site is an ancient Iroquoian village located on the Island of Montréal, next to Mount Royal. The site, which was initially located on a sand dune, covers about two acres.
De Havilland Beaver, DHC-2, successor to the Noorduyn Norseman, was the all-purpose bush plane of the Canadian North. The Beaver was sturdy, reliable and able to take off and land on short lengths of land, water and snow. It has been called the best bush plane ever built. While de Havilland produced it for only 20 years — from 1947 to 1967 — many Beaver planes still fly today. The Beaver helped connect communities in remote areas of Canada, in addition to serving across the globe.
De Havilland Caribou, DHC-4, twin-engined STOL aircraft capable of taking off in only 220 m. It was characterized by the sharp upward angle of the rear fuselage, providing access for large loads. It first flew July 1958, and was used mostly in a military role.
De Havilland Dash 7, DHC-7, STOL aircraft designed for efficient transport from city centres. It first flew March 1975 after a long development costing $120 million, four-fifths of which was paid by the federal government. Its
By the mid-1950s de Havilland realized the need for a larger, more powerful version of the DHC-3.
