The CNL Historic Waste Program Management Office and the Port Hope Area Initiative projects are situated on the traditional lands of the Williams Treaties First Nations, specifically the Gunshot Treaty negotiated between the Crown and Mississauga Nation during the 1780s and represented today by the Williams Treaties First Nations. The Mississauga Nations are also signatories to various 18th and 19th century treaties that covered lands in different parts of south-central Ontario. In 1923, the Mississauga First Nations and the Chippewa First Nations consisting of Rama, Beausoleil and Georgina Island signed the Williams Treaties and together, over 90 years later in June 2018, joined to ensure that their rights and the relationship with these lands are respected through a renewed agreement with Canada and the province of Ontario. The area in which we are situated is also home to Indigenous Peoples from across the region and Canada. CNL is grateful to have the opportunity to work on these traditionally and culturally significant lands and waterways.
