South Eastern Ontario offers some of the most unique and historically rich scuba diving experiences, particularly for those eager to explore underwater ruins, shipwrecks, and lost villages.
Let’s dive into the top spots every diving enthusiast should explore in this picturesque region.
One of the most intriguing diving locations is The Lost Villages along the Long Sault Parkway. These villages — Aultsville, Dickinson’s Landing, Farran’s Point, Iroquois, Maple Grove, Mille Roches, Morrisburg, Moulinette, Santa Cruz, Sheek/Sheil Island, Wales, and Woodlands — were sunk in 1958 during the creation of the St. Lawrence Seaway.
Today, the underwater remnants of these communities provide a fascinating glimpse into the past. Divers can explore submerged homes, roads, buildings, fences, and more, offering divers a unique combination of history and adventure.
For certified diving expert Marc Pilon, having The Lost Villages in his backyard gives him ample opportunity to dive. He’s a member of the Seaway Valley Divers and dives several times a week. “It’s always surprising,” he says.
One of his favourite underwater haunts is the lost village of Moulinette, located a couple of kilometres east of Long Sault, an area that has existed since the late 1700s. After seeing beautiful coral reefs and diving in the warmer tropics, Pilon says he’s seen some beautiful marine life, like manta rays, but nothing beats home and the history of the underwater world here. “My group and I always get excited about the next dive back home – so many things to discover.”
They use dive propulsion vehicles (or DPVs or scooters) to get to where they need to go, unencumbered, or back on track after the river’s current takes them on a side trek. Some of the fishes they encounter are the curious large and small-mouth bass, the big-eyed walleye, and four- or five-foot prehistoric-looking sturgeons found in the deeper water.
There were 10 communities and 7,000 people displaced during the flooding of the Seaway, so divers will see a lot of bricks, lumber, bottles, and cans. Rock walls of buildings, foundations, and the four-foot limestone blocks of old locks are still intact as part of The Lost Villages. “There are paved roads underwater. That’s very unique. If you discover the old Highway 2, you would be in the shallower waters and near the shore,” he said. There are also some bridges, like Hoople’s Bridge, an arch bridge made of cement, which is “a neat thing to see.”
To learn the history of The Lost Villages, check out the website and book a guided tour. These tours often include detailed narratives about the events leading up to the villages’ submersion, adding a layer of historical context to the underwater exploration.
Parks of the St. Lawrence has many interesting access points to explore the underwater history. When visiting the Long Sault Parkway, Lock 21 is known as one of Canada’s best surface dives. Located just off Macdonell Island, this dive will introduce you to the vast story of The Lost Villages.

The sight of these ancient vessels, now teeming with marine life, is a hauntingly beautiful experience.

The Comet, a paddle-wheeler that sank in 1861 after a collision, offers a more challenging dive due to its depth and strong currents.
