Plans to launch an invasion of Canada during the Revolutionary War (1775-1783) brought to light a major weakness in the country’s system of defence.

At the time, the St. Lawrence River was the only line of supply for the military posts around the Great Lakes. To reach these posts, which defended Canada’s western border, the British as to bypass several stretches of rapids located upstream from Montréal. The need to transport troops and merchandise around these obstacles by land slowed down the supply of these posts and made them more vulnerable.

Since the rapids at Coteau-du-Lac formed the most treacherous section of the river between Montréal and the Great Lakes, Sir Frederick Haldimand acted upon a recommendation of Captain William Twiss and had a canal built at this spot to speed up transportation on the waterway.

Sir Frederick Halimand
Of Swiss origin, Sir Frederick Haldimand began his career as an officier in the Prussian army in 1740. In 1755 he was recruited by the British army to serve an active role in the military operations in North America during the Seven Years' War.

He acted as military governor of Trois-Rivières from 1763 to 1764. He was then named governor of Canada in 1777.

Up until the end of the American Revolution in 1783, Halimand

devoted a great deal of time and effort in his capacity as governor to reinforcing the colony’s system of defence so that it would be able to withstand an American invasion.

Haldimand was replaced by Guy Carleton in 1786. He then returned to England where spent the rest of his life.

Les manoeuvres militaires visant à envahir le Canada, lors de la guerre de la Revolution américaine (1775-1783), avaient mis en évidence une faiblesse dans le système défensif du Canada.

À cette époque, le fleuve Saint-Laurent constituait la seule voie de communication permettant d’approvisionner les postes militaires des Grand Lacs, qui protégeaient la frontière occidentale du Canada. Pour s’y rendre, les britanniques devaient surmonter plusieurs rapides sur le fleuve, en amont du Montréal; l’obligation de contourner ces rapids par voie de terre ralentissait le transport des troupes et des marchandise, rendant ces posters plus vulnérables.

Le rapide de Coteau-du-Lac étant la plus difficile à franchir entre Montréal et les Grands Lacs, Sir Frédérick Haldimand, à la suggestion du capitaine William Twiss, fit creuser un canal à cet endroit pour accélérer le transport sur la voie fluviale.

En 1786, Haldimand fut remplacé par Guy Carleton. Il retourna en Angleterre où il termina ses jours.
