Gananoque's Thousand Islands Bridge across the St Lawrence

Why travel between Kingston and Montreal?

This route follows the mighty Saint Lawrence River which takes all the water from all the Great Lakes from Lake Ontario down to sea level at Montreal. You pass the Thousand Islands at the mouth of Lake Ontario, and just to the south along Highway 2 are many colonial era towns. At Morrisburg, you pass the Upper Canada Village which represents Canada in 1867, when it ceased to be colony and became a country. You will also pass a number of major dams on the St Lawrence, providing both navigable waters for ocean-going ships and Seaway freighters, but also generate power to the communities along or near the river. After crossing the Ontario-Quebec border, you cross the Ottawa River onto the Island of Montreal, which has several municipalities, including the City of Montreal.

Here is the itinerary for the 248 km from Kingston to Montreal along Ontario Highway 401, and Quebec Autoroute 20, known as the Macdonald-Cartier Freeway, to continue into Montreal on #40, the Trans-Canada HighwayMarine Museum at Kingston

The 206 kilometre long Rideau Canal connected Kingston and Ottawa, using the Cataraqui River from Kingston, and the Rideau River from Ottawa. Following the War of 1812-1814, England realized that it needed a protected route between Montreal in Lower Canada and York (Toronto) in Upper Canada. The canal used 47 locks and 24 dams to climb 49 metres (160 feet) above Lake Ontario, and then fall 84 metres (275 ft) back down to the Ottawa River. Today, the waterway is used primarily by recreational boaters, and passes through many quaint towns and villages, with plenty of shopping, dining and accommodation along the way.

The Thousand Islands (which actually number 1865 of them), lie in the St Lawrence for the 50 miles from the point where it drains from Lake Ontario. The islands range in size from a rock sticking out of water all the way up to Wolfe Island which is 27 miles long and 9 miles wide. They form a connection between the Canadian Shield and New York’s Adirondack Mountains just south of the border. In 1904 Canada designated some of the islands as part of the St. Lawrence Islands National Park. Visitors can take tours of the islands, which are popular with sailors and boaters from Canada and the US.

Thousand Islands Bridge, at GananoqueIn the 1950s, the US and Canadian governments created the St Lawrence Seaway, extends 3790 km inland from the Atlantic to the west end of Lake Superior. Dams created stable water levels and harnessed the St Lawrence’s hydroelectric potential while fifteen locks were built to handle ocean-going freighters.

The river was key to early exploration of North America’s interior, but it was a rugged waterway, punctuated with series of rapids, and at Niagara an insurmountable waterfall. Starting in 1829, small canals and locks were built for boats to bypass the rapids and the Niagara Falls, but they were massively expanded in the 1950s to handle international shipping. The largest locks and dams in this section of the Seaway are at Cornwall and at Lachine (Montreal).

East of Kingston, the route passes (but does not go through) the towns of Gananoque, Brockville, Prescott and Cornwall , which are all accessible by taking the old Highway 2 which meanders along the St Lawrence, and includes the Thousand Island Parkway between Kingston, Gananoque and Elizabethtown. A bit east of Morrisburg, midway between Prescott and Cornwall is Upper Canada Village, a Confederation-era village made up of buildings relocated there from  original settlements now underneath the dams of the St Lawrence Seaway, and staffed by re-enactors who create an experience of the daily life of that era.
