Sources: 4. Developments: 2. In September 2026, approximately 9,000 protesters, including members of the Grassy Narrows First Nation, marched through Toronto from Grange Park to Queen’s Park. The demonstration, known as the Grassy Narrows River Run, sought justice for the Ojibwe community regarding decades of mercury contamination in the English-Wabigoon river system. The protest addressed the impact of roughly nine tonnes of mercury released during the 1960s and 1970s, which has been linked to the Dryden Paper Mill. Activists and community leaders noted that mercury levels have not decreased significantly since the 1980s, with studies suggesting that approximately 90 per cent of the population suffers from some degree of mercury poisoning. Supporters, including labor unions, environmental groups, and organizations such as the United Church of Canada, called on provincial and federal governments to provide fair compensation. Key demands included the closure of the Dryden Mill, the halting of mining and nuclear waste plans in the region, and support to restore the community’s way of life. ## Timeline ### 2026-10-09: Grassy Narrows First Nation supporters march in Toronto for mercury justice Thousands marched in Toronto for the Grassy Narrows River Run, demanding compensation and an end to mercury pollution caused by the Dryden Mill that has affected the First Nation for decades. 2 sources. https://clstr.news/cluster/grassy-narrows-first-nation-supporters-march-in-toronto-for-mercury-justice ### 2026-09-23: Grassy Narrows supporters march in Toronto seeking mercury poisoning justice Thousands marched in Toronto to demand justice and compensation for the Grassy Narrows First Nation, seeking the closure of the Dryden Paper Mill due to ongoing mercury poisoning in their river system. 2 sources. https://clstr.news/cluster/grassy-narrows-supporters-march-in-toronto-seeking-mercury-poisoning-justice --- Cite as: Grassy Narrows mercury poisoning protests.
