[2] A modified version of Radio One, with local content replaced by additional airings of national programming, is available on Sirius XM channel 169.

It is downlinked to subscribers via SiriusXM Canada and its U.S.-based counterpart, Sirius XM Satellite Radio.

With the exception of CJBC, all 35 stations on the CBC Dominion Network were privately owned affiliates.

The Dominion Network operated only in the evenings, freeing affiliates to air local programming during the day.

In 1962, the Dominion Network was dissolved and within a few years CJBC became a French-language station broadcasting the programming of Radio-Canada.

The stations, located in Toronto, Ottawa and Montreal, broadcast a monoaural FM signal.

[4] The change spread to CBC regional morning shows which developed three hours of live radio combining "survival information", about news, weather and traffic, with interviews and documentaries about local and national issues.

CBC Radio Winnipeg was the first to embrace the format followed by Information Morning in Halifax, a move which increased audience and attracted coverage in Time magazine.

Until 1995, the network signed off the air between 1:00 a.m. and 6:00 a.m. daily (5:00 a.m. weekdays on its Toronto flagship station, CBL)– in that year, it launched an overnight program, CBC Radio Overnight, which airs international news and documentary programs.

From 2004 until early 2007, CBC Radio One promotional spots were announced by Canadian actress Shauna MacDonald, also known as "Promo Girl".

Definitely Not the Opera, Quirks & Quarks, The Vinyl Cafe, and Q are heard on some public stations in the northern United States.

Only stations licensed by the Canadian Radio-television and Telecommunications Commission as separate broadcast undertakings are listed below.

The only such operation still licensed is CKZN, relaying CFGB-FM from Happy Valley-Goose Bay, Newfoundland and Labrador with a 1 kW ERP signal on a fixed frequency of 6.16 MHz.

[9][10] Most schedules include hourly news readings that run from 4–10 minutes on the top of the hour except for major programming like the 6:00 p.m. news show, Your World Tonight, and the Sunday afternoon call-in show, Cross Country Checkup.

Typically for the noon and late afternoon time slots, national programs in the form of documentary specials are aired as well.

In addition, the programs featured on CBC Radio Overnight are not heard on the Sirius XM feed.
