Ontario - Where to Dive and Why

Why is easy. The province of Ontario is one of the richest places for divers. We have shorelines encompassing 4 of the 5 Great Lakes which gives Ontario divers an abundance of unique and diverse dive sites.

Ontario has shipwrecks, artificial reefs, caverns, cave systems, geological formations, drift diving, walls, sunken villages, large and small fish and lots of other interesting things.

Underwater photographers have no end of things to shoot. Underwater archaeologists are always busy doing site surveys.



Some of the most popular areas of Ontario for diving are:


Tobermory / Lake Huron | Kingston / Lake Ontario | Brockville | Lake Simcoe | Lake Erie / Lake St. Clair | Protected Heritage Sites


Tobermory and Lake Huron

The deep and sparkling waters at the mouth of Georgian Bay (Lake Huron) are home to Fathom Five - Canada's first National Marine Conservation Area. The park preserves a rich cultural legacy that includes more than 22 shipwrecks and several historic lightstations.

Fathom Five's freshwater ecosystem contains some of the most pristine waters of the Great Lakes. The rugged islands of the park are a reminder of the impressive lakebed topography found beneath the waves.

The park also has several caverns and the Bruce Penninsula hosts a little known cave system. Just outside the park are several artificial reefs including the Caroline Rose and the Niagara II.

Within the area of Lake Huron lie the wrecks of the storm of October 1913. There were 12 wrecks that foundered during the 1913 storm. Several of these are on the Ontario side of the lake and others have not yet been located. This was one of the worst storms that the Great Lakes had ever seen. The storm raged for hours, blowing down the length of Lake Huron, causing waves of 30ft or greater. Bodies and debris floated onto shore in the various waterways for days and weeks after the storm.

Some of these wrecks are in Ontario waters (or at least we think so), specifically the Wexford, the James Carruthers and the Hydrus.

Kingston and Lake Ontario

We separate Kingston from the rest of Lake Ontario due to the concentration of shipwrecks in the Kingston area.

In the Western basin, we have dives in the lower Niagara River, the Tiller wreck off St Catharines, various wrecks in the Burlington and oakville areas. There are numerous dives and wrecks around the Greater Toronto Area.

Divers should be aware that a permit is required to dive within the boundaries of Toronto harbour. Most dive shops in the area should be able to help you arrange for a permit.
