When did sir john a MacDonald bought Rupert's land?

Sir John A. Macdonald, the first Prime Minister of Canada, did not personally buy Rupert's Land; rather, it was acquired by the Canadian government from the Hudson's Bay Company in 1869. The transfer was formalized in a deal that was completed in 1870, which included the vast territories that now make up parts of several provinces and territories in Canada. This acquisition was crucial for the expansion of Canada westward.
