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.
“Today, we are taking a giant step forward in protecting Canada’s oceans. Working collaboratively with partner First Nations to cooperatively manage and designate the Tang.ɢwan—ḥačxwiqak—Tsig̱is MPA signifies our joint commitment to preserve ecologically and culturally important marine and coastal areas. The designation of this MPA brings us halfway to our goal of conserving 30 percent of our oceans by 2030,” stated the Honorable Diane Lebouthillier, Minister of Fisheries, Oceans and the Canadian Coast Guard.
“The Haida Nation recognizes the importance of Canada’s designation of the Tang.ɢwan—ḥačxwiqak—Tsig̱is Marine Protected Area. In October 2022, the Haida Nation designated the portion within Haida territory as a Haida Heritage Site. In June 2023, we participated as a partner in an ocean expedition with the Northeast Pacific Deep-sea Exploration Project to study the seamounts. Today, the joint designation demonstrates that all parties share a long-term commitment to ocean protection and biodiversity conservation and shows that a collaborative process can create meaningful measures to safeguard these unique deep-sea habitats,” added Gaagwiis Jason Alsop, President, Council of the Haida Nation.
Quick Facts
- The MPA’s name consists of a Haida word meaning deep ocean (Tang.ɢwan: phonetic spelling: Tung-Gwun), a Nuu-chah-nulth and Pacheedaht word meaning deepest part of the ocean (ḥačxwiqak; phonetic spelling:huch/khwi/kuk) and a Quatsino word referring to a monster of the deep (Tsig̱is; phonetic spelling: tsee-geese)
- All known Canadian hydrothermal vents and over 70 percent of all known Canadian Seamounts are within the Tang.ɢwan—ḥačxwiqak—Tsig̱is Marine Protected Area.
- The Tang.ɢwan—ḥačxwiqak—Tsig̱is Marine Protected Area repeals the existing Endeavour Hydrothermal Vents Marine Protected Area, capturing this important area in the Regulation.
- Commercial and recreational bottom contact groundfish fishing on the seamounts and in the hydrothermal vents area of the MPA have been closed since 2017.
- Canada and partner First Nations signed a Memorandum of Understanding (MOU) in January 2023. This cooperative management agreement was jointly announced by the parties on February 7, 2023, at the Fifth International Marine Protected Areas Congress (IMPAC5) in Vancouver.
- Canada’s newest MPA regulation will provide protection to the area in a way that is consistent with Canada’s MPA protection standard.
- Designating the Tang.ɢwan—ḥačxwiqak—Tsig̱is MPA adds 0.88 percent to the existing 1.44 percent from the 2017 Offshore Pacific Seamounts and Vents marine refuge. This increases the current protection of Canada’s oceans from 14.66 percent to 15.54 percent.
- The Nuu-chah-nulth Tribal Council, Council of the Haida Nation, and Pacheedaht and Quatsino First Nations have advanced their own designation processes as part of their inherent jurisdiction, in addition to the joint Tang.ɢwan—ḥačxwiqak—Tsig̱is MPA designation with Canada.
- Now that the Tang.ɢwan—ḥačxwiqak—Tsig̱is MPA is designated, and regulations for the MPA have been published in Canada Gazette Part II.
