1990
CBZ operated the following transmitters: CBAM Edmundston, CBAX McAdam, CBZB-FM Boiestown, CBZC-FM Bon Accord and CBZD-FM Doaktown. CBZ rebroadcasts programming originating with the CBC English AM network, and originated 21 hours and 50 minutes of locally-produced programming weekly.

1995
CBC Radio added overnight programming to its schedule on May 1, with "CBC Radio Overnight". The programming started out on certain CBC stations and was expanded to all of its stations by September. The program aired between 1:00 and 6:00 a.m. (local time) and offered reports from public broadcasters in 25 countries, with Canadian news on the hour. The program service was provided by the World Radio Network in London, England.

1996
On September 11, CBZ was authorized to add a transmitter at Woodstock, operating on frequency 91.9 MHz with an effective radiated power of 7.7 watts.  The CBC stated that the new transmitter together with that of CBZC-FM Bon Accord and CBZ would provide full CBC service to the area previously served by the private CBC affiliate CJCJ Woodstock. 

1997
On April 9, CBZW-FM Woodstock was opened.

The CBC Radio network (CBC Radio) was renamed "CBC Radio One" on September 1.

2001
As of 2001, CBZ operated the following transmitters: CBAM Edmundston, CBAX McAdam, CBZB-FM Boiestown, CBZC-FM Bon Accord, CBZD-FM Doaktown, and CBZW-FM Woodstock. CBZ broadcasts approximately 15 hours of local programming each week from Fredericton.

2002
On December 18, the CBC was authorized to convert CBZ to the FM band, operating on 99.5 MHz with an effective radiated power of 3,200 watts. The new FM signal would alleviate significant reception problems for Radio One listeners caused by a much smaller night-time contour on the existing AM frequency in the Fredericton area. CBZ offered approximately 15 hours of local programming each week. The CBC stated that the local program Fredericton Information Morning from 6 a.m. to 9 a.m. each weekday was unavailable to many people in the listening area, particularly during late fall and winter months. The new FM station would provide reliable coverage throughout the year.

2003
On August 21, CBZ was given approval to add a rebroadcast transmitter at Edmunston to replace the existing CBAM-AM facility. The new FM transmitter would operate on 99.5 MHz with an effective radiated power of 24,000 watts.

2004
CBZ-AM was replaced by CBZF-FM on April 15.

On June 8, CBAN-FM Edmunston signed on, replacing the old AM facility.

CBZ 970 left the air June 22 after a simulcast period with CBZF 99.5.

2007
CBZF-FM received approval to make technical changes for CBZC-FM at Bon Accord. Average effective radiated power would increase from 5,700 watts to 15,800 watts (maximum ERP from 5,700 watts to 44,200 watts). There would be a slight increase in antenna height (EHAAT) from 296.9 metres to 301.9. The antenna radiation pattern would be changed from non-directional to directional. CBC/ Radio-Canada proposes to replace its CBZC-FM antenna system and combine the new one with its planned French-language FM mono transmitter CBAF-FM-21 recently authorized at Bon Accord.

2008
On October 21, the CBC received approval to change the frequency of CBZW-FM Woodstock from 91.9 MHz to 95.3 MHz. The application was filed to reduce the possibility of interference with its French-language FM transmitter CBAF-FM-21 Bon Accord, which would operate at 91.7 MHz once implemented.

Late in the year, CBZF-FM was authorized to change its technical operation for CBZC-FM Bon Accord to reflect the as-built parameters. Average effective radiated power would decrease from 15,800 to 14,000 watts (maximum from 44,200 to 38,500 watts). Antenna height (EHAAT) would increase from 301.9 to 320.4 metres. The changes would allow CBZC-FM to achieve the equivalent previously authorized parameters with practically identical service contours.

2009
On May 12 the CRTC renewed CBZF-FM's licence. The renewal included the following rebroadcast transmitters: CBAX McAdam, CBZB-FM Boiestown, CBAN-FM Edmundston, CBZC-FM Bon Accord, CBZD-FM Doaktown and CBZW-FM Woodstock.
