Covering 133,017 square kilometers, the Tang.ɢwan—ḥačxwiqak—Tsig̱is MPA is home to extraordinary seafloor features, including more than 47 underwater mountains, known as seamounts, and all known confirmed hydrothermal vents in Canada. These deep-sea biological “hotspots” support rare and unique deep-water species that are both remarkable and culturally important.

Formerly known as the Offshore Pacific Area of Interest, this deep-water ocean area was first identified for protection in May 2017, and measures to prevent certain fishing activities were subsequently put in place. In 2023, the Council of the Haida Nation, the Nuu-chah-nulth Tribal Council, Quatsino First Nation, Pacheedaht First Nation, and Canada signed a Memorandum of Understanding outlining how the parties will collaboratively manage the Tang.ɢwan—ḥačxwiqak—Tsig̱is MPA.
In addition to designating this MPA under Canada’s Oceans Act, each partner First Nation has advanced their own process to designate the area. Ensuring full protection of this important area has been a collaborative effort centered on marine protection and reconciliation.
