The Sonar
The Sonar was made by Constantin Chilowsky and Paul Langevin with the help of Canadian R.W Boyle. The sonar's purpose was to detect objects underwater using sound waves, such as submarines, boats and mines. This invention was very convenient during World War One because of its ability to identify anything dangerous such as enemy vessels in the waters and avoid it. (Ross, 2016) -
Curtiss C-1 Canada twin-engine bomber
In 1915, the Curtiss C-1 was tested near Toronto. This twin-engine airplane was the first to be built and flown in Canada. After the success of this airplane, Curtiss built a Model H flying boat designed to fly non-stop across the Atlantic Ocean. (mreman47, 2014) -
Lewis Light Machine Gun
In 1915, Issac Newton Lewis designed the Lewis Light Machine Gun. This gas operated machine gun was different from the ones used during the time period because of its advantageous features. Its portable size and weight of 28 lbs allowed for one soldier to easily carry and use it.
This light gun replaced the heavier machine guns used by Canadian soldiers during World War I. (2021) -
Nissen Hut
In 1916, Canadian-British engineer and inventor Peter Nissen created a corrugated iron semicircular hut ideal for housing troops during World War I. The design of this hut deflected shrapnel and bomb blasts. It was very easy to transport and assemble especially during wartime. (2021) -
Canadian National Railway
The CN Railway that was incorporated in 1919, is the longest railway system with 31,000 kms of track between the United States and Canada. It connects three coasts that include the Atlantic, Pacific and Gulf of Mexico. It is primarily used to transport goods in various industries. (Albert Tucker, 2009) -
Insulin
In 1922 Dr. Frederick Banting, a professor at the University of Toronto and fellow researchers, Collip and Macleod invented insulin to control human metabolism and prevent diabetes. In 1923, they received the Nobel Prize for a very important breakthrough in medical history.(Michael Bliss, 2015) -
The Variable Pitch Propeller
In 1922 Wallace Turnbull, a Canadian Engineer, made the first variable pitch propeller. This invention allowed pilots to adjust the angle of the blades at the front of the aircraft while flying. This meant that they could adjust the pitch depending on the mode of flight. For example, they used a low pitch during takeoffs and climbs.(Ingenium – Canada's Museums of Science and Innovation, 2016) -
The Snowmobile
In 1922, a mechanic from Quebec, Joseph-Armand Bombardier designed a propeller-driven sled using a Model T-Ford engine and two wooden sleds. This development was the first vehicle to operate and move across the vast regions of the Canadian snow covered lands.(Chris Debresson, Nathan Baker, 2006) -
Battery Less Radio
Edward S. Rogers invented the battery-less radio in 1925. This radio was used by many Canadians to listen to music. Instead of requiring batteries, it ran on electricity and used a vacuum tube that produced a clearer sound.(Ingenium – Canada's Museums of Science and Innovation, 2016) -
1925 The Snowblower
Arthur Sicard, a Canadian inventor, created the first snowblower in Quebec 1925. Parts of the snowblower were made of a corkscrew shaped blade made of metal that was supposed to collect the snow and dispense it. Some two stage snow blowers also have a storage compartment which collects the snow. This makes it easier to clean areas covered in large amounts of snow.(David Berry, 2020)
