During 1865-68, Schultz was owner of the Nor'Wester, and in its columns attacked the "tyranny" of the Hudson's Bay Company. He became the leader of the small
but noisy Canadian Party, which demanded annexation to Canada and which roused Métis fears.
Imprisoned by Louis Riel's provisional government on 7 December 1869, Schultz escaped on 23 January 1870. He later made his way to Ontario, where he and others of the Canada First movement raised Protestant ire over the execution of Orangeman Thomas Scott. No mention was made of the deaths of Hugh Sutherland and Norbert Parisien for which Schultz and others were responsible.
