Why did the Canadian Government want to gain control of Rupert's land?

The Canadian Government sought to gain control of Rupert's Land primarily to expand its territory and assert sovereignty over the region, which was rich in Natural Resources. The acquisition was seen as essential for fostering economic development, facilitating westward expansion, and establishing Canadian presence in the face of potential American encroachment. Additionally, controlling Rupert's Land would help integrate Indigenous populations into the Canadian Confederation and promote settlement and agricultural development in the West.
