Put it this way. If this plane went down in Hudson Bay we would know within 100 feet where it hit water.

Disagree, for the reasons stated above. You apparently know about our ADS-B sites around the bay, but they're not immune from the problems stated above.
And we apply the same separation at the periphery of secondary radar coverage (~250 nm) that we do within 100 miles, which is to say we don't consider it sketchy... our opinion is kinda the only one that matters as far as that's concerned.
