Retirements and declining immigrant participation have Canada facing a critical shortage of engineers

The Canadian government took delivery of a HYSUB 5000 ROV in 1987. Designed and manufactured by International Submarine Engineering (ISE) of Port Moody, BC, the HYSUB is an electrohydraulic submersible remotely operated vehicle, operating with 6 to 250 hp.

Sustainability is the ability of the biosphere, or of a certain resource or practice, to persist in a state of balance over the long term. The concept of sustainability also includes things humans can do to preserve such a balance. Sustainable development, for instance, pairs such actions with growth. It aims to meet the needs of the present while ensuring that future people will be able to meet their needs.

Sweat lodges are heated, dome-shaped structures used by Indigenous peoples during certain purification rites and as a way to promote healthy living.

A synchrotron is a source of brilliant light that acts like a giant microscope to allow matter to be seen at the atomic level. Synchrotron light is millions of times brighter than sunlight and millions of times more intense than conventional X-rays.

In 1961, fragments of a human infant skull from were recovered from the banks of the Oldman River near Taber, Alberta.

Talc is a mineral composed of 31.7% magnesium oxide (MgO), 63.5% silicon dioxide (SiO2) and 4.8% water. It is formed by the alteration of dolomite or ultramafic IGNEOUS rocks. A formula for pure talc would look like this: 3 dolomite + 4 quartz + 1 water = 1 talc + 3 calcite + 3 CO2.

Tantalum (Ta) is a grey, heavy, very hard metal with a high melting point (2996°C). When pure, it is ductile and can be easily fabricated. Tantalum has good rectifying properties (ie, converts alternating to direct current) and dielectric properties (ie, does not conduct direct current).

TC Energy Corporation (formerly TransCanada Corporation) is a natural gas, oil and power-generation company headquartered in Calgary, Alberta. TC Energy owns more than 92,600 km of natural gas pipeline in North America and transports more than 25 per cent of the gas consumed on the continent. It also operates power plants and gas storage facilities. A public company, it trades on the Toronto Stock Exchange and the New York Stock Exchange under the symbol TRP. In 2018, TC Energy registered $13.7 billion in revenue and $3.5 billion in profit and held $98.9 billion in assets. The company employs about 7,300 people, more than half of them in Canada.

From its origins in manual training "shop" and industrial arts, technical education has consisted of practical and applied subject matter that reflects the practices of current society.

They're everywhere. Turn on the TV, pick up a newspaper or magazine, and the stories leap out: stem cells to heal the body's failing nervous system; transplanted wombs; the smaller-than-small world of nanotechnology; and yes, as in the previous story, the feverish quest for an artificial heart.

Technology is the manipulation of the physical world to achieve human goals.

Telecommunications is defined as the electronic communication of information over distance. In theory, this definition covers all forms of electronic communication and does not distinguish between different kinds of information: voice, data, text and video.

In 1868 the Montreal Telegraph Co began facing direct competition from the newly established Dominion Telegraph Co and price wars broke out.

The invention of the TELEGRAPH (1837) by Samuel Morse and the telephone (1876) by Alexander Graham BELL were milestones in the quest to communicate over great distances with reliability, accuracy and speed.

Overlaying these two perspectives is the reality that Canadians have long been among the world's most avid television viewers with tastes that do not necessarily discriminate between domestic and foreign content, or between entertainment and education.

Telidon, a combination of the Greek words meaning "to know at a distance," was a waypoint en route to the Internet and was an early demonstration of how technology can provide on-demand access to information.

In 1885, smallpox gripped the city of Montreal.

The story of the Arrow had its origins in the Cold War and the growing spectre of Soviet bombers invading our northern skies.

The Canadian Science and Engineering Hall of Fame is a permanent exhibition at the Canada Science and Technology Museum that honours individuals whose outstanding scientific or technological achievements have had long-term implications for Canadians.
