The Canadian Broadcasting Corporation was formed to take over the operations of The Canadian Radio Broadcasting Commission. The CBC re-started National Carbon's CKNC Radio to supplement the Toronto coverage of CRCT. The call letters for the reborn station became CRCY operating on 1420 kHz with 100 watts of power. 
 

Frequency of CRCY moved from 1420 to 960 kHz.

CRCY changed its call letters to CBY. 

CBY moved back to 1420 kHz. Power remains 100 watts.

On March 29, CBY moved from 1420 kHz with 100 watts to 1010 kHz with 1,000 watts, from a new transmitter site located along Highway 5, one mile southwest of Sommerville Corners.

CBY became CJBC. 

On January 2, the CBC formed a second English network, The Dominion Network, with CJBC as the flagship station. CBL anchored The Trans-Canada Network. 

CJBC began broadcasting on 860 kHz with 50,000 watts power from CBL's Hornby transmitter site. Both stations shared one 647 foot tower and operate with non-directional patterns. 
 
CFRB had been on 860 kHz. The CBC which regulated radio at this time, arranged with to CFRB to switch frequencies with CJBC. CFRB moved to 1010 kHz.

CJBC began providing a half-hour of news and commentary in French from Montreal, weeknights at 10 p.m. On Saturdays and Sundays a 10 minute newscast in French aired at 10 p.m.
       
In July, the half-hour weeknight French service was increased to one hour with the addition of a nightly half-hour of variety programs from the French network. 

The Dominion and Trans-Canada networks consolidated into one network on October 1. On this date, CJBC began airing two hours of French programming each weeknight, beginning at 9 p.m.

French programming on CJBC expanded on January 1, to 7:00 p.m. to  10:30 p.m. weekdays and 7:00 p.m. to sign-off on weekends. 

On October 1, CJBC went French full-time, except for 10:30 p.m. to 1 a.m. Five and a half hours per week were locally produced French programs, the remainder comeing from the French network Radio-Canada. 

On April 3, CJBC opened re-tranmitters in Belleville (95.5 MHz)  and Kingston (99.5 MHz).

The Midland-Penetanguishine repeater (96.5 MHz) started December 1.

CJBC started its London repeater(99.3 MHz) on December 10. 

CJBC Peterborough (106.3 MHz) went on the air October 1.

CBL/CJBC erected a new tower at the same site.

CJBC and all of Toronto's CBC operations started to move into the new Canadian Broadcasting Centre at 250 Front Street West.

CJBC Belleville moved from 95.5 to 94.3 MHz.
