Hi everyone! this might be a long shot to find any info but if anyone will know anything, it would be the great people on this forum. I have been looking into the CFS Shelburne site and have explored the base itself multiple times but there is one rumor that I can't shake about it. I have heard that there is a bunker under that site. Here is my question: does anyone have any kind of conformation that this rumor is true? Pictures would be greatly appreciated.

Yes and no. There wasn't exactly a bunker, but there was a listening station maybe a half km out under the water. It was likely collapsed by DnD when they decommissioned the site. Even if it's still there, it's certainly full of water by now - apparently it had problems with water even when the base was operational.

CFS Shelburne land was part of a WW-II era Canadian military facility, but the CFS was established during the Cold War to be a monitoring & processing station for the Submarine Sound Surveillance System, which used hydrophone arrays linked by hardened, waterproof cable to a regional station (in this case, CFS Shelburne), which then passed the data on to other Canadian, US & NATO operations.

By the mid-1990s, system modernization resulted in a modern system called the Integrated Undersea Surveillance System, which re-used many of the existing hydrophone arrays, but instead of the hydrophone lines feeding regional processing stations, the data was now remotely fed to a facility in Halifax.

That resulted in CFS Shelburne being closed and apparently partially abandoned, partially re-used. HOWEVER, the hydrophone array should still feed the Terminal Building on-site, but the data is automatically then fed to Halifax. That means that one secure building, or a secure area of a building at the old CFS, is still used by the Canadian Forces, albeit unstaffed.

Here are my images of NAVFAC Point Sur, a SOSUS station operated by the US Navy in the same era:

P.S. Another old CFS you should investigate is CFS Mill Cove.

And by the way, there likely wasn't a bunker. "Secret bunkers' and "secret tunnels" are common rumors for military sites, and while in rare cases they are true or somewhat based on the truth (a hardened building may have actually been used for weapons storage, there maybe have been steam tunnels to provide heat to various buildings...), often it's just urban-legend.

The only things that CFS Shelburne should have had going out into the water would have been the hydrophone cables, possibly a sewage pipe/stormwater drains, and maybe a small boat people could take out for recreational fishing...

I was just looking into this myself, wouldnt mind figuring out what these old earthwork structures in the middle of the airfeild are.

Those are old decommissioned aircraft munitions bunkers at Shearwater. Those would've been in use from the 40's until probably the mid-80's.
