Darn, some glitch just erased what I started with...
Retry: Elan, after reading that AOW students go on these wrecks and they die, I read back through the Ontario Underwater Council incident reports back to 2000 and find no mention of these kind of deaths.

The charter operator I use will not take OW divers out onto these two wrecks, and even with AOW they want you to work up to these wrecks with shallower dives if you have not done this kind of cold water diving before.
Finally, the Forest City lies on a slope, it ran into Bears Rump Island and sank, what's left of the midships begins in 60 ft, the mooring block for boats is in 70 ft, while the stern is in 150. I read your post as sounding like folks are jumping straight into 150 ft of water with an Alu 80. You could dive this wreck and stay above 80 ft easily.
I don't see or hear of AOW classes on either of these wrecks, so who's taking them out there?
