Ten Tons of Mercury. They Knew. They Wrote It Down.
In the 1960s and early 1970s, a chemical plant in Dryden, Ontario discharged enormous quantities of mercury into the English-Wabigoon river system.
The contamination accumulated in fish and devastated communities downstream, particularly Grassy Narrows First Nation, where fishing was central to food, culture, and the local economy.
Documents and investigations in the decades since have raised disturbing questions about what industry and government officials knew, when they knew it, and how the contamination was handled.
Mercury doesn't simply disappear when the dumping stops. Its effects can persist through an ecosystem—and through communities—for generations.
