Band members said more than 60 per cent of band members voted for the deal, which would see the band own a share of the Keeyask dam and share profits. The revenue, plus cash compensation for flooding of the band's traditional land, will funnel at least $80 million into the community over the next 25 years.
Chief Duke Beardy couldn't be reached for comment, and Manitoba Hydro, which has yet to comment on the multimillion deal, did not return calls.
War Lake First Nation, a tiny reserve with just over 300 members, also ratified a similar deal Thursday.
The $5-billion Keeyask dam is slated to be built on the Nelson River and would pump out 695 megawatts, making it one of the biggest ones in the north.
