The Kwikwetlem First Nation has filed an Aboriginal title and rights and Charter claim with the Supreme Court of Canada.
The first nation says the claim is an effort to ensure its title and rights over key areas in its traditional territory.
In this case, the territory is based around the watershed of the Coquitlam river, which has seen significant development over many years.
Areas in the case filed amount to less than 1% of Kwikwetlem’s core territory, and includes the Colony Farm Forensic Psychiatric Institute.
The first nation says it hopes that the case will help to ensure it is meaningfully involved in decisions made about its lands, a process highlighted by the Supreme Court of Canada.
