When members of Asubpeeschoseewagong Anishinabek (Grassy Narrows First Nation) and their supporters arrive at Queen’s Park this week, they’ll be calling for the Dryden pulp and paper mill that’s been poisoning their water with neurotoxins for nearly 60 years to permanently close. “We want everybody to be compensated, we want the mill to shut down, and we don’t want no mining or logging in our territory,” says Chrissy Isaacs, lead organizer of the caravan. Isaacs has been a staple of the annual River Run demonstrations since they began in 2010. She is currently travelling Toronto from her community near Ontario’s western border to protest the downriver effects of methylmercury poisoning. …In May, scientific researchers released the revelation that sulphate and organic matter in the effluent that the mill is still releasing into the river is making methylmercury in the river system even worse, as opposed to diminishing over time as they were told.
