The Saint-Lawrence River was used as a direct entry point for European colonizers as they made their way through and across the land that was eventually renamed Canada and the United States. Their arrival and use of the waterway eventually facilitated industrialization and its resulting ecological destruction, the extraction and depletion of the land's natural resources, and violence against Indigenous peoples that still continues today.
A special thank you to Alex Arsenault for answering my questions and helping me better understand some of the fundamentals of Canadian law.
