The Oka Crisis was a land dispute between a group of Mohawk people and the town of Oka, Quebec, Canada which began on July 11, 1990 and lasted until September 26, 1990. Sûreté du Québec (SQ) Corporal Marcel Lemay was killed by a bullet whose source has never been officially determined. Rumours circulated that the reason no source had been determined was that it had been a police bullet and that Cpl. Lemay had been conducting an internal investigation which was connecting the death of two Mohawk men to SQ guns. The dispute was the first well-publicized violent conflict between First Nations and the Canadian government in the late 20th century.
