An Act to establish National Thanadelthur Day

Bill S-274 was a Senate Private Member's Bill establishing February 5 as National Thanadelthur Day, honouring Thanadelthur (also spelled Thanadelther, circa 1697-1717), a Chipewyan Dene woman who served as an interpreter and peacemaker between the Cree and Chipewyan Dene Nations and the Hudson's Bay Company. Thanadelthur is recognized as one of the first known Indigenous diplomats in what became Canada, brokering peace between the Cree and Chipewyan Dene that allowed HBC trading at York Factory to expand in the early 18th century. The bill was sponsored by Senator Mary Jane McCallum (Manitoba, the first First Nations woman appointed to the Senate of Canada in 2017, member of the Barren Lands Cree First Nation). Did not pass third reading in 44-1; reintroduced as Bill S-225 in 45-1.
