News of the Cypress Hills Massacre did not reach Ottawa until late August 1873, therefore the event itself was not very well known in Canada. The Canadian government soon took steps to have those involved extradited from the United States and tried for murder, causing confrontation between Canada and the United States. The case languished for some time and then was taken up by the newly created North-West Mounted Police (NWMP). The NWMP at this time was still establishing itself; the battle between the Assiniboine warriors and Hardwick's group of wolf-hunters at Cypress Hills was one of the catalysts for its creation.
