The history of telegraphy in Canada dates back to the Province of Canada. While the first telegraph company was the Toronto, Hamilton and Niagara Electro-Magnetic Telegraph Company, founded in 1846, it was the Montreal Telegraph Company, controlled by Hugh Allan and founded a year later, that dominated in Canada during the technology's early years.
Following the 1852 Telegraph Act, Canada's first permanent transatlantic telegraph link was a submarine cable built in 1866 between Ireland and Newfoundland.Telegrams were sent through networks built by Canadian Pacific and Canadian National.
In 1868 Montreal Telegraph began facing competition from the newly-established Dominion Telegraph Company. 1880 saw the Great North Western Telegraph Company established to connect Ontario and Manitoba but within a year it was taken over by Western Union, leading briefly to that company's control of almost all telegraphy in Canada. In 1882, Canadian Pacific transmitted its first commercial telegram over telegraph lines they had erected alongside its tracks, breaking Western Union's monopoly. Great North Western Telegraph, facing bankruptcy, was taken over in 1915 by Canadian Northern.
By the end of World War II, Canadians communicated by telephone, more than any other country. In 1967 the CP and CN networks were merged to form CNCP Telecommunications.
As of 1951, approximately 7000 messages were sent daily from the United States to Canada. An agreement with Western Union required that U.S. company to route messages in a specified ratio of 3:1, with three telegraphic messages transmitted to Canadian National for every message transmitted to Canadian Pacific. The agreement was complicated by the fact that some Canadian destinations were served by only one of the two networks.
