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. -
The Sonar
The Sonar was the first of what is one of the most important things on a military boat now. The Sonar is a system that uses underwater sound waves to detect and find items, submarines boats and mines. It is also used to detect depth in water, diving safety and communication at sea. This device was very helpful for battles on the water during world war one as canadian ships were able to detect anything that could potentially be dangerous and avoid it. -
Lewis Light Machine Gun
Canadians first went to war with 4 Colt machine guns. The Colt machine gun was a good weapon but it was immobile and often jammed after rapid fire shots. It was later replaced in 1916 by the Vicker machine gun which was a heavier and immobile but more reliable machine gun. Soon after it was replaced by the Lewis Light machine gun. It was a reliable machine gun that did not weigh a lot and could be carried around. This helped advance some of canada's war tactics and help them a lot on offence. -
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. -
The Snowmobile
In 1922 Joseph Bombardier who had been known for playing with mechanics, started playing around with a ford engine and some wood and constructed the first snowmobile. At the time he was 15 and his dad made him take it apart because there was an open propeller and it could have seriously hurt Joseph. -
The Discovery Of Insulin
For a very long time scientists had always thought that the key to preventing diabetes and controlling a normal metabolism was some kind of internal secretion of the pancreas. Finally in 1921 at the University Of Toronto a team of doctors led by Dr. Fredrick Banting decided to approach it from a different angle. By the spring of 1922 Dr. Fredrick Banting and his team were able to announce the discovery of Insulin. -
The Variable Pitch Propeller
In 1922, Canadian engineer Wallace Turnbull made the first variable propeller. It was one of his most successful inventions and was so good that the government showed some interest in it and started testing it at camp Broden. Unfortunately it was destroyed in a fire at camp Broden but was later remade the Propeller in 1925. 2 years later the canadian air force successfully tested it and sold it to 15 manufacturing companies -
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. It could throw the snow up to 90 feet or just store it in the back of the truck. -
Battery Less Radio/AC Tube
Edward was the first person to invent a battery less radio. His goal was to invent a radio that ran off of the household electricity current. Because of the little electricity it required it was a hit and was sold all over canada. -
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. The expansion of the expansion of the railway was the cause to a lot of good consequences such as access to a new saltwater port and transportation. -
The Expansion Of The Hudson Bay Railway
Canada’s railway system was one of the best and they weren’t done with it. The construction of the Hudson Bays railway was finished and officially opened in 1929. It was built to provide access to another saltwater port. -
Continuity and Change
The weapons in World War 1 changed alot over time. 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. The discovery of insulin was a huge achievement. Being able to treat people with diabetes was huge but the treatment did not change for a long time. It stayed the same and worked the same way for a long time.
