The Canadian Broadcasting Corporation (CBC) emerged out of the Canadian National Railway Ottawa (CNRO) radio network. CNR President Henry Thornton believed radio broadcasts would enhance the experience of travellers as well as facilitate management of the railway system. In fact, CNR workers would use handheld radios to keep track of freight cars across Canada.

Beginning as a relay station for route information, CNRO soon began to broadcast programs that it thought would educate and unite Canadians such as high brow drama and classical music.

CNRO operated out of the Jackson Building on Bank Street between 1924 and 1929 before moving to the Chateau Laurier directly opposite Union Station. From there the CBC would transmit for eighty years until moving to its current location on Sparks Street in 2004.

The formation of a coast-to-coast railway and radio network were important elements in shaping Canadian national identity. With so much of the CBC now located in Toronto and Montreal, it is worth remembering that the Jackson Building, the Chateau Laurier, and Union Station played such an essential role in the making of Ottawa as the nation’s capital through railways and radio waves.
