That was the official sign on of CKGW at 910 AM, a commercial station owned by Gooderham and Worts, with studios at the King Edward Hotel.

CBL established a large low-power relay transmitter (LPRT) network in Northern and Central Ontario during the 1950s and '60s.

Its nighttime signal reached much of the eastern half of North America (including three-fourths of Canada).

Now, signing off, from CBL, adieu.The CBC subsequently surrendered two relay transmitters outside the city which duplicated the CBLA signal.

The CBC Jarvis Street Tower site was demolished in 2002 to make way for the RadioCity condominium development.

On October 4, 2021, CBLA added HD Radio operations, as part of upgrades in Toronto, Ottawa and Vancouver.

On weekend mornings the station produces Fresh Air, hosted by Ismaila Alfa and heard throughout Ontario.

Saturday afternoons the station broadcasts an arts and culture magazine, Big City, Small World, hosted by Mariel Borelli.

Similarly, the aforementioned Big City, Small World is replaced by CBLA-FM-2 Kitchener-Waterloo's In the Key of C (formerly CBO-FM Ottawa's Bandwidth until its cancellation) on all of the station's rebroadcasters outside Toronto.

Since October 2005, Here and Now has begun at 3 p.m. on CBLA's main transmitter in Toronto, unlike most CBC Radio One stations whose local afternoon programs begin at 4 p.m.

However, the station's rebroadcast transmitters outside of Toronto air regular CBC network programming for the first hour and join Here and Now in progress at 4.

CBLA's rebroadcaster in Crystal Beach, which serve areas within commuting distance of Toronto, normally air Metro Morning instead of Ontario Morning, but otherwise abides by the schedule used by other rebroadcasters – it carries neither the 3 p.m. hour of Here and Now, nor any other specially-scheduled programming specific to the Toronto area.

In September 2011, the CBC announced plans to launch a new local radio service for the Kitchener-Waterloo area beginning in fall 2012, re-using the existing transmitter, CBLA-FM-2 (89.1 FM) in Paris.

[12] The new station commenced programming on March 11, 2013,[13] but was later forced to resume rebroadcaster-only service in April, due to a misunderstanding of the application details and the conditions of the repeater license.

[15] Prior to its sign-on, CBLA-FM-2 carried the same schedule as the provincial CBLA feed, apart from Metro Morning (Kitchener-Waterloo, like Crystal Beach, is also within commuting distance of Toronto).

On July 4, 2014, the CBC submitted an application to convert CBLV Bancroft from 600 kHz to 99.3 MHz; this was approved on September 23, 2014.

While mostly relaying programming from CKGW, it would also air a regular specialty programme for DXers in the International Short Wave Club.
