Thomas Munro, Chief Engineer for the Soulanges Canal

The decision to build a new canal on the north shore of the river and close the Beauharnois Canal on the south shore sparked numerous disputes and heated debates.


In 1889, the federal government entrusted Thomas Munro (1831-1903) with the task of conducting a feasibility study and drafting a detailed plan for the new canal.


In June 1890, he submitted his final report, which included the proposed name 'Soulanges Canal', the route, construction phases, and implementation details.


At the beginning of 1891, the project was officially approved, and the responsibility for overseeing this massive undertaking naturally landed on Thomas Munro. Expropriation procedures began for the land needed for the project, and by autumn, the first construction contracts were awarded.

Considered one of the finest engineers of his time and employed by the Department of Railways and Canals in Ottawa since 1890, Thomas Munro earned a solid reputation through the completion of several major projects.

Among his achievements were his contributions to the Victoria Bridge and the Montreal Aqueduct, as well as overseeing the reconstruction of the Welland Canal.

The Soulanges Canal was the crowning achievement of his career. He served as its chief engineer from 1889 until his death in 1903 at his home in Coteau-Landing.
