XWA, was a Marconi station in Montreal and the call letters stood for “experimental wireless apparatus”.
The first scheduled broadcast was in May 1920, also predating American broadcasts becoming the oldest radio station in the world, although actual broadcasts were very limited, and nothing like the 24/7 operations of today.
By 1920 XWA had changed it’s call sign to CFCF which it retained for decades. Those call letters stood for “Canada’s first, Canada’s finest”. Much later the TV operation would also use those call letters.
It remained a highly popular radio station and changed owners over the years, and call letters as well.
In 1991 it was CIQC, and a news format. In 2005, another format change to news-talk, and in 2008 a switch to all-hits radio. But AM radio was dying, and in Montreal a percentage of the Anglophone audience had moved out of Montreal and the mainly French-speaking province.
With the combined factors of a reduced audience, the fading of AM radio in popularity generally, and its remaining audience split amongst several competitors, there was clearly trouble on the horizon by the 2008 switch to all hits music.
In 2010, using the call sign CINW 940AM, owners Corus Entertainment shut the operation on January 29th. At 10:00 am the programming ceased and looped messages were played explaining that given “current economic conditions” continuing to broadcast was impossible.
At 7.02 that evening, the broadcasts simply stopped and the first and oldest of radio stations, certainly in North America, and possibly the world , went silent.
