Site Description

Beneath the St. Lawrence River lies the submerged village of Mille Roches, one of the Lost Villages affected by the St. Lawrence Seaway construction in the late 1950s. Mille Roches was a thriving community, its economy dominated by a prominent paper mill that played a pivotal role in the village’s industrial activities.

History

Mille Roches’ story begins with industrial ambition. In 1904, Michael Davis, alongside business partners from Cornwall, Ontario, established the Cornwall Paper Company. The mill was constructed on the eastern side of the village, producing paper from rags and recycled materials. However, financial instability forced the company to sell in 1909 to American investors from Kalamazoo, Michigan.

Under the new management, the mill flourished. It became an industry leader in the 1930s, earning recognition for its safety standards. By the 1940s, the mill employed over 100 millhands, cementing its importance to the village’s economic stability. Ownership shifted to Provincial Abitibi, later known as the Provincial Paper Company, which expanded operations and modernized production methods.

The village’s fortunes turned in the early 1950s with the development of the St. Lawrence Seaway, which necessitated flooding to create the waterway. By 1952, uncertainty over the future led to the mill’s closure and relocation to Thorold, Ontario, where a modern facility was established. Mille Roches, alongside other villages, was evacuated and submerged.

Final Disposition

Today, the remnants of Mille Roches rest underwater as part of the Lost Villages, offering an eerie yet compelling glimpse into the past.
