In 1972, following the archaeological work, the Coteau-du-Lac area was officially recognized as a
National Historic Site. In 1982, restoration work was begun to develop the heritage values associated with the military, commercial, home-building and industrial activities which took place at Coteau-du-Lac and to commemorate the major role played by the site in the development of transport and communications in Canada.

As the forerunner of today's St. Lawrence Seaway, the Coteau-du-Lac canal recalls the birth of river transport technology in the country, and highlights the strategic and economic importance of the St. Lawrence River, the main route for penetrating into the heart of the North American continent.
