Summary

Thousands of people marched through downtown Toronto on September 23, 2026, to protest outside the Ontario legislature as part of the annual Grassy Narrows River Run. The protest was led by Grassy Narrows and Wabaseemoong First Nations, who are demanding compensation for ongoing impacts of mercury contamination in the Wabigoon-English river system and closure of the Dryden Paper Mill (also referred to as Dryden Fibre pulp mill). The mercury contamination dates to the 1960s and 1970s when approximately nine tonnes of mercury were dumped into the river system. Despite repeated efforts to meet with the province, including sending letters and organizing protests, the First Nations leaders have not received a response from Premier Doug Ford or Indigenous Affairs Minister Greg Rickford.
