Infamous "Diefenbunker" Contains An Old CBC Radio Studio

If you're old enough, you might have heard about this before. It was a sanctuary built beneath the ground in Ottawa by then P.M. John Diefenbaker, at a time when Cold War tensions were at a fever pitch. 

There's a lot of stuff there, buried deep beneath the ground - and one of them is an old CBC radio studio, designed to keep the network on the air and Canadians informed in the event the worst happened. Thankfully, it never did.

But the structure remains and it's now a tourist attraction. 

"The radio room is recognizable by the intended output, a broadcast. A telephone exchange belongs to the network that connects conversations."

Haven't been there yet, but have seen some photos, including the vintage radio studio. The bunker is near the community of Carp, in the rural part of the City of Ottawa that some locals still refer to as "West Carleton".

Some of you may be old enough to remember the DND's comms installations at Edenvale and Brentwood, not far from CFB Borden. The Edenvale site, which began as an RCAF detachment and is now a private airport, had a number of radio towers on the property along Highway 26, east of Stayner, plus a bunker; as a child, I remember seeing the towers and (at night) the red lights on them, whenever we'd drive past on the way to or from my hometown of Collingwood. When the two sites were decommissioned around 1994, Barrie's CKVR was at the Edenvale site as the towers were being pulled down, and I used to have that report on videotape... wish I still had it today.

That would be a worthwhile tour when visiting Ottawa.  The nation's capital is a wonderful city and quite underrated.  Lots of museums and things too see.  Great radio town too!
