Plongee Sous-Marine Summum

This is the only local dive site in the Montreal area that allows you to reach 100 feet deep. This freshwater quarry is open Tuesday evenings and during the day over the weekends. There is a $20 cash only access fee to be paid upon arrival.

From the wharf, you have a surface or underwater swim of about 400m in order to reach a cliff of about 30m deep. Bring a light as it gets dark quickly in this lake. Also, pay attention to where you are swimming and look ahead as there are lots of downed trees laying around in the lake.

This site is located near Parc des Ancres. A lot of parking available. There is also a large covered area suitable for completing log books. This site is used extensively for training. The water here is shallow with a maximum depth of 7 meters. The area is protected by mounts on three sides and the water is calm.

The St-Zotique underwater park boasts four wrecks: the Fédéral 11, The Teddy W, The Anne-Marie G, and the Fédéral 4. There are multiple anchors all linked together with cables so divers do not get lost.

This dive site is in the old Canal Soulange (no longer in use). It has an interesting location near Parc des Ancres (where you will find many old ship anchors). The site is shallow with very calm water. As such, it is easy to silt it up so take caution.

In 1958 the St-Lawrence seaway was created. The depth of the seaway was increased to allow larger ships to travel to the Great Lakes. As such many villages, road ways, locks, power houses, canals were submerged and can be seen by divers.
