The Trophy Lodge is a commercial tourism and sport fishing lodge that has been operating since 1965. It is located within Thaidene Nëné National Park Reserve which was created in 2019.

Conditions to approval were added to address SSN’s concerns.

  • Successfully overturned the Governor in Council’s decision to approve the Trans Mountain Pipeline Project before Federal Court of Appeal (Tsleil-Waututh Nation v. Canada (Attorney General) 2018 FCA 153) on that basis that the Crown failed to adequately consult and address impacts from the project on the Nation’s Aboriginal rights and title, in particular noting failure to engage with the Nation about project’s proposed route which passes through a cultural heritage site.

Her Majesty the Queen, a July 10, 2012 decision of Pizzitelli J.
