The mercury contamination has caused health problems for some members of the First Nation.

The community is dealing with generations of mercury poisoning from contaminated water.

The chief of a northwestern Ontario reserve – and an NDP candidate in this fall's federal election – is calling on Indigenous Services Minister Seamus O'Regan to sit down to hammer out an agreement on a long-promised treatment facility for mercury poisoning.

Grassy Narrows Chief Rudy Turtle said the Liberals haven't done enough to help with mercury contamination.

OPP say they were called to assist a man who had been allegedly assaulted on a road in Grassy Narrows First Nation in the early hours of Tuesday morning.

"They understand what we're asking for," said Chief of Grassy Narrows First Nation Randy Turtle.

A UN human rights expert says the need to address mercury contamination in Grassy Narrows dates back some 50 years.

Help for the community experiencing the effects of mercury contamination seemed to be on the way when the federal government promised a specialized treatment facility on the reserve in November 2017.

The unidentified woman called on the federal government to make good on its promise to provide a mercury treatment centre for the northwestern Ontario community.

The chief of a First Nation in northwestern Ontario long-plagued by the debilitating impacts of mercury contamination says he is worried about the fate of a federally promised treatment facility.
