Prescott Scuba Park
2026-10-08 18:00 - 21:00 (America/Toronto) | Prescott Scuba Park, 100 Centre St, Prescott, Ontario, Canada
This is a great dive spot for divers at any level. There is a small wreck and a couple of old anchors to see. In 2023 the city added a porta-potti and change rooms and in 2024 will add a scuba bench.

Morrison's Quarry
2026-10-10 10:00 - 13:00 | Morrison’s Quarry, 1780 Route 105, Chelsea, Quebec, Canada
This popular site has many attractions including a plane and other items of interest. The water is typically very cold though at any depth so a two layer wetsuit is required with a hood and gloves.
A good reference site is: https://www.neptune-scuba.info/ca/qc/carriere-morrison-en.html
The fee is $20 for entry (cash) to be paid to the quarry owners and a valid FQAS card is required. An FQAS card can be acquired at local dive shops but may require a course to acquire depending on the shop. In fall 2021, Scuba Finatics ( https://scubafinatics.ca/) seemed to be the best source for these cards. Plan well in advance if you need a new or updated FQAS card.
The following image indicates the artifacts to dive.

Lock 28 to Connie drift
2026-10-15 18:00 - 21:00 | Lock 28 to Connie drift, 100 Galop Canal Rd, Township Of Edwardsburgh/Cardinal, Ontario, Canada
This is a great short drift dive starting at the “Wreck Wee Hawk”. We then swim to the entrance of Lock 28 and then drift downstream and eventually cross into the main channel and end up on the Conestoga (Connie), where you can loop around. We often also dive back to near the entrance location.
In the bottom left of the image below, you can see the “Wreck Wee Hawk”.

Lock 21
2026-10-18 10:00 - 13:00 | Lock 21, Macdonell Island, South Stormont, Ontario, Canada
Lock 21 is a fairly high current dive so should only be done by advanced divers who are comfortable with higher current dives. It is located off the south-western end of Macdonell Island near Long Sault.
Web information sources:

SOS provides a great description and sketch of the lock: https://saveontarioshipwrecks.ca/diverguides/lock-21/

Location: Lock 21 is located off the south-western end of Macdonell Island. From highway 401, take exit 778 toward Long Sault. Take the South direction on Moulinette Road up to Highway 2 (also known as King’s Highway). Continue heading South direction on Moulinette Road crossing Highway 2 toward Long Sault Parkway. Follow the route toward McDonell Island (2nd island)stop at the beech are of the 1st Island, Mille Roches Island to purchase a $10 dive pass, then continue to McDonell Island. After driving half way across McDonell Island, take the 2nd gravel road to the left. It will go only for about 40 meters then turn right to travel toward the West direction. It will end in about 60 meters. There is a brown pavilion where information is available about the dive site and an historic tour relating the story of the Lost Villages after the construction of the St.Lawrence Seaway. The Lock is located on the South side of the island on the St.Lawrence lake (not the St.Lawrence River which is located on the other side of the islands on the American side of the border). The GPS location is: 44°59’55.0″N 74°53’57.4″W (44.998611, -74.899270)
If you happen to drive along the Long Sault series of islands from the west end, stop at the 1st island, McLaren Island camping area and purchase the $10 diving pass from the small shop by the parking lot, then carry on to McDonell Island.

Lock 25
2026-10-22 18:00 - 22:00 | Lock 25, 105 Boat House Road, Iroquois, Ontario, Canada
This is a shallow, almost no current dive. We simply travel around an old lock. There can be some pike or carp or other interesting fish depending on the time of year. It is recommended to use a dive float as their can be some boat traffic. You will also want to have a light.
The image below shows the parking area in blue or you can park along the side of the road. The red line shows the general dive plan. There are six orange buoys which are tied down by chain, which can be seen underwater.

Centeen Park / Gaskin
2026-10-24 10:00 - 12:00, 2026-11-05 18:00 - 21:00 | Centeen Park, Centeen Park Brockville, Brockville, Ontario, K6V 1A3, Canada
This is a great spot to check out your gear and visit the underwater statues or do something more adventurous.
The inner area has been populated with wonderful life-sized statues. Click on the image below to see the SOS PDF on this site.

Secondly, advanced, fully equipped (NLT 100cuft tank) and ideally with a pony bottle, can visit the Gaskin from shore. Click on the image below to see a site about it with a great 3D model.

Rockport Wall
2026-11-01 10:00 - 12:30 | Rockport Wall, 19 Front Street, Rockport, ontario, Canada
This is a good dive spot for basic and advanced divers as it is a steep wall. There is also a small wreck. Divers must stay close to the west wall to avoid boat traffic.
There is a $10 free to be paid at the bar of the Cornwall’s Pub.

We dive from the beech area just to the north of the Boat House hotel / restaurant and motel. You can park in the beach parking lot area. See the image for the RV (beach) area.

Connie
2026-11-07 10:00 - 11:30 | Connie (Conestoga), Legion Way, Edwardsburgh/Cardinal, Ontario, Canada
The Conestoga (Connie) is a great shore dive wreck. Since the water will be colder at this time of year we will keep it simple and skip the drift to the Connie. This will allow any diver to end their dive quickly if they get cold.
