so where does XWA Montreal fit into it?

[Kevin Vahey]

When talking about commercial radio at the beginning one has to
include XWA Montreal that started in 1919 and then became CFCF in
1920. The station was owned by Marconi of Canada for years. They got
shafted in their final dial placement of 600 as CKAC was given the
blowtorch at 730.

Today the license lives on 940 and for the most part is playing oldies
that FM stations in Montreal can't (only the CRTC could come up with
that)  They tried to be news-talk when they moved to 940 but it never
caught on as CJAD just owns the market.
