The chief of a northern Manitoba First Nation that has been under a boil water advisory since 2018 says he's frustrated by a lack of action from the federal government on funding upgrades to its water treatment plant — an issue the First Nation is taking to Federal Court next month.

Shamattawa First Nation's boil water advisory stems from an issue that peaks during the spring, when the ice clogs the treatment plant's intake line, resulting in brown, contaminated water pouring from people's taps.

Chief Jordna Hill said an end to the boil water advisory is "nowhere in sight," and it has significant effects on the well-being of people in the community of nearly 1,500.
