I just got off the phone with my mother in law in Cornwall, Ontario and had a long discussion about the lost villages of the St Lawrence Seaway.
The Seaway was created to let large ocean going vassals travel from the Gulf of the St Lawrence all the way to Lake Superior. The government of Canada at the time thought it was a financially viable venture because they believed it would help business greatly.
Unfortunately for Canada, the real benefactors of this mammoth project were the coastal American towns around Mesena, NY.
The entire St Lawrence between Cornwall and Montreal was deepened and widened, as a result, many towns and villages were flooded and lost.
Many of the buildings were removed and transferred to a outdoor museum called “Upper Canada Village”
The lost towns were
Aultsville
Farran’s Point
Dickensen’s Landing
Moullinette
Milleroches
Woodlands
There may be a couple more…
My wife and I sometimes camp at Woodlands Park, and from there, on a clear sunny day, you can see sidewalks and roads under water, it’s really a creepy feeling to see old Highway #2 disappearing under water right before your eyes.
Also when you get out on the river, in certain areas you can see the tops of chimneys coming straight up from below, but not protruding the water of course.

I’ve tried in vain to find photos, but to no avail.
Next time I’m there I can take some photos of the roads underwater, if that would help.
Good luck
