Ontario Drowned 10 Villages in 1958 to Build a Canal. The Old Highway Still Drives Into the Water

See why a paved Ontario infrastructure project inexplicably disappears beneath the surface of the St. Lawrence River. This video explores the strange sight of a road that continues underwater, passing by old stone foundations and submerged structures. We examine historical footage of boats and bus lines to piece together the narrative behind this site, suggesting a larger history of logistics and development in the region. By reviewing these abandoned roads, we can better understand the planning that once existed in areas now reclaimed by the water. The submerged grid structure offers a glimpse into how historical sites are lost to changing geography, serving as a reminder of the industrial activity that defined the riverfront long before it was left to the current.
