The Radio

The radio was one of the greatest communication devices ever invented in the 1920's. Radio signals from around Canada could now broadcast the weather, news, music, advertising, and etc. People from the countryside were no longer isolated from the city because they were able to fill themselves with knowledge about what was going on around Canada from the information that was being broadcast from the radio. The firs radio broadcast was on May 20, 1920 when the Montreal station XWA broadcast a musical programme to a meeting of Royal Society in Ottawa. The radios became more and more popular overtime and soon there were around 300,00 radios in Canada.

The Telephone

Alexander Graham Bell was the inventor of telephoned and his first one was made in Brantford Ontario.The first dial telephones appeared in Toronto in May 1924 and were seen as noisy and difficult to use. But three years later, the handset, mouthpiece and earphone combined together and came into much use. By 1929, the telephone the phone was very popular and 3 out of 4 families had one so that they could make domestic or oversea calls.


The first car was created in the 1920's by Henry Ford. Ford wanted his product to be a in-expensive car that everyone could buy and afford so he invented the Model T, also known as Tin Lizzy, which cost about $365. This car made traveling way faster and easier for families and caused the expansion of suburbs. In 1929, the automobile industry was very big and the top three companies were "General Motors", "Chrysler," and "Ford." The only problems that the automobiles caused were pollution, traffic jams, accidents, and ways where criminals could escape quickly from their crime scene.


Stunt flyers and air travel was part of Canada's history in the 1920's. Canadian pilots were coming back from war and wanted to keep connected with aviation and so therefore bought their own planes for stunt performances. Planes in the 1920's were also used for spotting forest fires, taking aerial photos, and geological surveys. In 1929, when a case of Deptheria outbroke in Alberta, planes were used to deliver medicine. The governemnt and the public realized the potential of aiplanes and decided to also use planes, particularly small carrier planes to fly people from city to city as an easier way of transportation .
