      The only reason I thought about it was because I was a SONAR tech in the Navy and had friends in IUSS and SURTASS. Long-range passive SONAR like that is fascinating.

        I suppose Canada would want (and probably has) these to surveil the bay. I doubt their military installations would be on most maps of undersea cables.

        I would guess it’s fiber optic cables to provide telecom access to remote communities though. It’s likely a lot cheaper and easier to run undersea cables there than it would be to run thousands of kilometers of cables overland through remote wilderness and then maintain them when they’re inevitabily damaged.

          Possibly, but I don’t think the location of those cables is a secret. I think about a decade ago Russia was cutting US undersea surveillance cables.
