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.
