Dive Site Overview for Ontario

Ontario is one of the best places in the world for freshwater shipwrecks –there are hundreds of wrecks that have become amazing artificial reefs and remain in fantastic condition, free from salt corrosion and in clear waters.

All diving is focused around the Great Lakes and Rivers and the occasional quarry. Wrecks are the number one reason for diving in Ontario! They range from 18^th century schooners to more modern freighters and steel vessels. Often the deeper wrecks are in better condition than some of the newer, shallower wrecks since they are protected from storm and ice damage.

Lake Erie has many wrecks to choose from and something for all skill levels. Try The Raleigh (a steamer sunk in 1911), The Carlingford and the George C Finney are just a few popular sites. Lake Superior and Lake Michigan offer a vast range of dive sites and are popular with tech divers and rebreathers.

Kingston is a major Great Lakes port with plenty of wrecks to choose from. Try the Munsun, an old dredging vessel, or The Aloha now encrusted with zebra muscles which help to improve the visibility.

Freshwater diving here really is fresh –expect temperatures of around 4°C! Apparently in late summer the surface temperature of the great lakes and other shallower bodies of water may reach up to 20°C but generally speaking you will need a thick wetsuit or drysuit for diving (maybe also some regulator antifreeze).
