This project lasted 4 years and was completed in 1921. The project was the largest engineering project since the Panama canal. The electricity from niagara falls was used for many different industries including but not limited to mining, the paper industry as well as being used for many factories.]]> 2022-09-21 02:02:48 UTC https://padlet.com/350448874/mgj70499c4gelyto/wish/2305973057 350448874 https://padlet.com/350448874/mgj70499c4gelyto/wish/2305974925 By the 1920 gas powered tractors were starting to be used in Canada.

They discovered the drug in the university of Toronto after experimenting on a diabetic dog where they took the insulin from the healthy dog’s pancreas and injected it into the diabetic dog which allowed him to stay alive for 70 day before running out of the injected insulin.

It was an important invention for the transportation of material and people in the harsh terrain of the north as well as aiding in hunting. Even though he made his first prototype of the snowmobile in 1922 it wasn’t until 1937 that he patented the system and later he opened a very successful snowmobile company.]]> 2022-09-21 02:11:00 UTC https://padlet.com/350448874/mgj70499c4gelyto/wish/2305983233 350448874 https://padlet.com/350448874/mgj70499c4gelyto/wish/2305985526 Viscose rayon is an artificial fiber made from cellulose which is found in wood pulp. Starting in 1925 Viscose rayon was starting to be manufactured and exported out from Canada. The mass production of Viscose rayon was first started in Canada by the British, setting up a factory in Cornwall Ontario. This was important because the rest of the world needed this material as they were running out this became a great revenue source for Canada this added an incentive for them to export.
