Cornwall is on the St. Lawrence Seaway, opposite Massena and Rooseveltown, New York. The 1958 seaway eliminated rapids upstream at Long Sault, opening a path for large ocean-going vessels from the Great Lakes at the expense of inundating and destroying several small villages (such as Aultsville and Moulinette). Some historic buildings which were displaced from the Lost Villages are now at Morrisburg (Upper Canada Village) or Long Sault (Ault Park); islands along what is now the Long Sault Parkway were once part of the Canadian mainland. Long Sault and Ingleside are planned communities to house displaced villagers.
Cornwall-Massena is the home of a large hydroelectric generating station (with visitor's centre) and large ships may be viewed transiting the Seaway locks. Much of the city's industrial base is now gone, as is the pollution associated with Cornwall-Massena in the 1970s.
Cornwall is on Highway 401 (exit 789), about one hour west of Montreal and two hours east of Kingston. As Ontario's easternmost city, Cornwall appears as a control city on highway signage for over a hundred miles from Kingston (exit 611) eastward.
From Montréal, Autoroute 20 west becomes Ontario 401.
VIA Rail serves Cornwall from Montreal and Toronto. The railway station is located at 1650 Station Rd.
Coach Canada serves Cornwall from Montreal and Toronto.
The closest major airport is Montréal-Trudeau YUL IATA, from which direct onward connections are available by rail from the Dorval commuter train station. Ottawa also has a major airport, but Ottawa-Cartier (YOW IATA) is no closer than Montréal and lacks Dorval's relatively easy air-to-rail connection.
Cruising on small craft is an option on the St. Lawrence Seaway, but there is a minimum length at the locks (about 20', which excludes some small boats which can be carried by auto trailers) and the huge "Seaway Max" ships are given priority - one of these leviathans fills an entire Seaway lock with only inches to spare.
As the Seaway is fresh water and the Cornwall-Massena border is 45°N (halfway to the North Pole), shipping through the locks is inherently seasonal, typically ending in December and re-opening near the end of March.
