At its creation, Prime Minister Bennett spoke of the need for public control of radio saying:
The three-man commission had a mandate to regulate, control all broadcasting in Canada as well as to create and transmit its own programming and to lease, purchase or construct stations for its dissemination. Its ability to carry out its mandate was severely restricted by the financial constraints of the Great Depression and it was forced to rely on private stations to carry its programs to much of the country.
Bennett named Hector Charlesworth, editor of Saturday Night magazine, as chairman of the CRBC. The other members of the Commission were Thomas Maher, an unsuccessful Quebec Conservative candidate in 1930 federal election and director of a private radio station in Quebec City and Lieutenant Colonel W. Arthur Steel.
E. Austion Weir, formerly of the CNR radio network, became the CRBC's program director. He was terminated, however, for not providing enough programming. Weir was replaced by Ernie Bushnell who became director of CRBC programming in Ontario and Western Canada and Arthur Dupont who was responsible for Quebec and the Maritimes.
Another CRBC program, one which originated on the CNR's network in 1931, was Hockey Night in Canada under the names Saturday Night Hockey, General Motors Hockey Broadcast and then, starting in 1934, The Imperial Oil Hockey Broadcast. Other programming including fare such as Bible Dramas from CRCM Montreal, Canadian Press News - a 15 minute nightly newscast from CRCT Toronto presented by Charles Jennings (the father of Peter Jennings), Western Radio Players a weekly dramatic half-hour from CKY Winnipeg and Northern Messenger, a weekly program originating from Toronto but aimed at Canadians living in the far north including personal messages to RCMP officers, missionaries, trappers and others from family and friends, the program was continued by CBC into the 1970s.
CRBC's coverage of the 1935 federal election was the first time Canadian election results were broadcast nationwide.
All programs were live as there were no recording facilities. The network had six stations of its own and relied largely on private affiliates to provide studios, equipment and staff.
In April 1936, CRBC provided round the clock coverage of the Moose River Mine Disaster in Nova Scotia with announcer J. Frank Willis broadcasting live reports from the mine head every half hour for five days as rescue crews attempted to recover the lost miners. The reports were broadcast throughout Canada as well as to 650 stations in the United States and the BBC.
In 1935, CRBC provided nationwide radio coverage of the 1935 federal election, the first such national broadcast in Canada.
The CRBC turned to radio advertising in order to make up a shortfall between government grants and the amount of money needed to run the network.
During the election campaign, the CRBC broadcast a series of 15 minutes soap operas called Mr. Sage which were critical of Opposition leader William Lyon Mackenzie King and the Liberal Party. Decried as political propaganda, the incident was one factor in the King's decision to replace the CRBC with a new entity when the Liberals took office following the election.
New legislation was introduced creating the Canadian Broadcasting Corporation as a crown corporation with an arm's length relationship with the government. The management of the CRBC, including Charlesworth, were dismissed and the new CBC was launched on November 2, 1936 with a new management team.
At its demise, the CRBC was made up of eight network owned-and-operated stations and 14 privately owned network affiliates.
The CRBC's regulatory powers were largely transferred to the CBC while the role of licensing stations and allocating wavelengths was assumed by the newly created Department of Transport. In 1958, the Board of Broadcast Governors assumed responsibilities for regulating public and private broadcasters from the CBC and the Department of Transport and in 1968, with the adoption of the Broadcasting Act, regulation became the responsibility of the Canadian Radio-television Commission (CRTC).
