The Sonar
Sonar (sound navigation and ranging), method for locating objects by the reflection of sound waves. It is used naturally by such animals as Bats and Dolphins to locate food and obstacles. Sonar was first developed - as a practical method of detecting underwater hazards (eg, submarines, icebergs) and for measuring water depths by Constantin Chilowsky and Paul Langevin in France during WWI, with the collaboration of the Canadian R.W. Boyle. -

The process to extract helium from natural gas
In 1915 Sir John Cunnungham Mclennan was working on a way to extract it and finally figured it out. He then gave this info to the canadian government and started making extraction plants to help with the war. of crude helium from natural gas typically requires three processing steps. The first step is the removal of impurities. Amine and glycol absorption, dry desiccant adsorption, and/or other extraction processes typically remove water, carbon dioxide, and hydrogen sulfide. -
Machine Guns
Machine guns inflicted appalling casualties on both war fronts in World War One. Men who went over-the-top in trenches stood little chance when the enemy opened up with their machine guns. Machine guns were one of the main killers in the war and accounted for many thousands of deaths. -
Ontario Hydros Queenston-Chippawa Hydroelectricity Power Generator
Ontario Hydros Queenston-Chippawa power generator project was under construction for 4 years (1917-1921) and was one of the largest engineering projects since the Panama Canal. This huge hydroelectricity generator not only provided light and power to urban areas and factories, it was very much linked to mining, paper and pulp, and aluminum processing. It was used a lot in the war. -
The Radio
The radio was a great communication invention of the 1920s, Radio signals across Canada could now broadcast voices, news, weather, sports, music and many other things. People in the remotest areas of Canada were no longer isolated and were brought in contact with other cities of the nation. -
The Telephone
One of the most significant advancements in telephone communications in the 1920s was the advent of automated exchanges. Previously, people needed to contact an operator who would then connect the call. Automated exchanges allowed for personalised numbers to be dialled from home and directly connected. -
The Snowblower
Arthur Sicard a canadian inventor was trying to make a machine that helped farmers get snow off their fields in an easy and quick way. He started his work in 1894. It took him 31 years to create this machine and finally he unveiled it in Montreal. The first snowblower was a very different machine, it was pretty much a truck with a scooper and a snow throwing chute. -
The Expansion Of The Hudson Bay Railway
Two of western Canada's earliest railway charters, granted in 1880, authorized construction, with government help, of railways parallelling old water transportation routes to Hudson Bay. The projects were amalgamated in 1883 and the first 64 km built northward into the Manitoba interlake region. -
Cause and Consequence
The construction of the Ontario Hydros Queenston-Chippawa Hydroelectric power generator is a great example of cause and consequence. Building the generator had good consequences such as providing electricity and power to urban areas and factories. It had some bad consequences as well such as destroying part of the environment in the area. -
Continuity and Change
The telephone has changed so much from back then. As you see the telephone changed by the structure of it and the purpose of it to. Another thing that changed is the Machine guns were immobile and unreliable. By the end of the war they were light, and reliable. Not only did canada work on these weapons during the war they continued their research after the war so they would be ready for the next war.
