The last living survivors of the thousands who were uprooted by the St. Lawrence Seaway come together to preserve the legacy of their lost villages. The construction of the St. Lawrence Seaway began in 1954 and is recognized as one of the most monumental engineering and construction achievements in history. In the name of economic progress and nation building, over 6,500 residents were relocated from their villages as they watched their homes flooded and submerged under the great St. Lawrence River. In a visual journey to the past and present, the last generation of these Lost Villages share their memories buried and unearthed, lost and found, and their commitment to keeping the legacy alive as they strive to build their own future.
