Anishinaabe film actor Adam Beach will be using his star power to help the Grassy Narrows First Nation in its “fight for mercury justice compensation” in an online rally this week. “After many decades of tirelessly pursuing justice, Grassy Narrows has won important commitments to improve care for mercury sufferers, reform the Mercury Disability Board and clean up the English-Wabigoon River,” reads the Free Grassy Narrows group’s website.

CBC News reported last week that a new study on the people living in the Grassy Narrows First Nation suggests mercury exposure continues to affect the health of people living in the community. Residents of Grassy Narrows, which sits 80 kilometres north of Kenora, Ont., have complained about mercury contamination that has affected the physical and mental health of the Ojibway community. During the 1960s and 1970s, a Dryden, Ont., pulp mill dumped 9,000 kilograms of mercury into the English Wabigoon River and the federal government has promised to build a $68.9-million facility to help care for people living with the impacts of the chemical, CBC News reported.

The online rally to support the Grassy Narrows First Nation will take place on Saturday, March 26, at 2 p.m. EDT.

Beach, 49, who was born in Ashern, Man., has played roles in Smoke Signals, Dance Me Outside, Walker, Texas Ranger, Joe Dirt, Flags of Our Fathers, Windtalkers, Bury My Heart at Wounded Knee, Law & Order: Special Victims Unit, Skinwalkers, Coyote Waits, A Thief of Time, Arctic Air, Suicide Squad, Squanto: A Warrior’s Tale, Hostiles, and Juanita. He most recently played Edward Nappo in Jane Campion‘s The Power of the Dog, which stars Benedict Cumberbatch, Jesse Plemons, and Kirsten Dunst and has been nominated for Best Picture in this year’s Academy Awards on March 27.
