A former national chief of the Congress of Aboriginal Peoples has passed away.

A cause of death wasn’t given, but in a release, the Congress says Dwight Dorey passed away earlier this morning in Nova Scotia.

Dorey, a Mi’kmaq from Cole Harbour, Nova Scotia, was elected to his first term as CAP’s national chief in 2000.

He served in that capacity until 2006, and then was re-elected to his fourth term as the Congress’s national chief in 2015.

Dorey also served as the organization’s senior policy advisor and is credited with helping launch the Daniels case in 1999 with the late Harry Daniels.

That legal action would eventually see the Supreme Court of Canada rule in 2016 that Metis and non-status Indians are “Indians” under the Constitution.
