Freshwater wrecks, island cruises and river history on the Canadian St. Lawrence.
Overview
Brockville and Rockport are Canadian gateways to historic shipwrecks in the upper St. Lawrence River. Parks Canada points to local wreck charters, while Dive Brockville/Abucs offers conventional day-boat departures and a shore-access sculpture park. Strong river currents, ship traffic and wreck depth demand site-specific qualification. Non-divers can cruise the Thousand Islands from Brockville or Rockport, visit the Brockville Railway Tunnel, hike selected national park trails or take a guided kayak trip from Gananoque. This is a road-and-boat itinerary, not a dive liveaboard destination. The U.S. shore and U.S.-water wrecks are excluded even if marketed from a Canadian shop, as are separately launched Picton dives. Summer gives the strongest range of activities; park facilities have a shorter season than the dive charter operator advertises.

The Centeen Memorial Dive Park offers an accessible sculpture-site alternative to deeper fragile historic wrecks, with current conditions still requiring evaluation.
