Cornwall (Ontario)

Cornwall is a small city on the St. Lawrence River in Eastern Ontario.


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.

Get in

By car

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.

From Ottawa-Hull, take the Trans-Canada Highway 417 to Casselman, then turn south on Ontario 138.

By train

VIA Rail serves Cornwall from Montreal and Toronto. The railway station is located at 1650 Station Rd.

By bus

Coach Canada serves Cornwall from Montreal and Toronto.

By air

The closest major airport is Montréal-Dorval IATA: YUL, from which direct onward connections are available by rail from the Dorval commuter train station. Ottawa also has a major airport, but Ottawa-Uplands is no closer than Montréal and lacks Dorval's relatively easy air-to-rail connection.

There is a tiny airport in Massena with a few federally-subsidised US flights daily to Albany.

By seaway

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.

By horse

Get around


Cornwall Jail. Do not pass GO, do not collect $200





Ontario's drinking age, at 19, is high by Montréal standards (Québec is 18) but almost looks reasonable next to Massena (USA is 21).




Bed and breakfast



Open wi-fi is also available at ONroute (401 westbound rest stop at the provincial border) and McDonald's (hamburger stand with two Cornwall locations).
