The Stop Line 3 protests are an ongoing series of demonstrations in the U.S. state of Minnesota against the expansion of Enbridge's Line 3 oil pipeline along a new route. The new route was completed in September 2021, and was operational on 1 October 2021. Indigenous people have led the resistance to the construction of the pipeline, which began following the project's approval in November 2020. Opponents of the pipeline expansion, called water protectors, have established ceremonial lodges and resistance camps along the route of the pipeline. Enbridge has funded an escrow account that law enforcement agencies may draw on for pipeline-related police work. Organizers have arranged marches and occupations of Enbridge construction sites. Following the blockade of an Enbridge pump station on June 7, 2021, nearly 250 people were arrested. Invoking treaty rights, organizers established an encampment at the headwaters of the Mississippi River at a site where Enbridge intends to bury the pipeline.
