The Mackenzie Valley Pipeline Inquiry was enacted fifty years ago in 1974 by the Canadian Government. Library and Archives Canada (LAC) holds the original collection of the Inquiry records, which are managed by Government Archives Division.

This is the final blog of a three-part series on the Mackenzie Valley Pipeline Inquiry (MVPI). This blog will focus on providing instructions on locating a selection of specific types of MVPI records through Collection Search.

Discovering MVPI digitized collection materials

The records of the MVPI were transferred to the Public Archives of Canada in February 1978. All MVPI records are open to the public for research purposes, though not all MVPI records are digitally accessible online.  A digitally accessible record will show the digitized image of the record above the Record Information Page when retrieved and opened through Collection Search. These records can be requested and accessed on-site at LAC.

Resources for records searches

The following information provides more specific guidance on searching for MVPI records.

The main sous-fonds is titled Mackenzie Valley Pipeline Inquiry (multiple media), or you may find it by using the search term “Mackenzie Valley Pipeline Inquiry” in Collection Search to find the result “Reference: R216-165-X-E, RG126. Date: 1970-1977”. Additional keywords for searches may include “Berger Commission” or “Berger Inquiry”.

The MVPI sous-fonds contains three main groups of series-level records, which are Transcripts of proceedings and testimony (digitized), Exhibits presented to the Inquiry (digitized) and Operational and administrative records (not digitized).

Each record may contain an electronic link to a related finding aid. This is found in the “Record information – Details section” and listed as “Finding aid: show detail”.

1 – Transcripts of proceedings and testimony – Reference: R216-3841-6-E, RG126

Please note: Shortcuts for locating both “formal hearings transcript” and “community hearings transcript” files using Collection Search are listed after section 3 – Operational and administrative records.

For formal hearings, reference “R216-172-7-E, RG126. Date: 1974-1976. Digitized”.

The sub-series includes 217 digitized transcript files, which are identified by number and location. The majority of the formal hearings were held in Yellowknife, with the remainder held in Inuvik (Northwest Territories), Whitehorse (Yukon) or Ottawa (Ontario).

Finding aid 126-5 is a verified file list of the formal hearing transcripts indicating transcript number, file title (the location), dates and permanent volume numbers.

For community hearings, reference “R216-169-7-E, RG126. Date 1975-1976. Digitized”.

The sub-series includes 77 digitized transcript files. Transcripts are identified by number and location. Community hearing transcript numbers are prefixed with the letter “C”.

Finding aid 126-8 is a verified file list of the community hearings transcripts including transcript number, file title (the location), parts, dates and permanent volume number.

Finding aid 126-3, from pages 111–120, is a list of Inquiry community witnesses and includes transcript numbers. In order to locate the Inquiry community transcript, preface the transcript number with the letter “C”. For example, to find text about “Antoine Abalon”, enter the search terms “Mackenzie C-18”. The result is Transcript Number C18 – Fort Good Hope, NWT. Scroll down list of names to Antoine Abalon, p. 1795.

2 – Exhibits presented to the Inquiry – Reference: R216-3840-4-E, RG126 Date: 1972-1977

Community hearings exhibits “R216-168-5-E, RG126 Date: 1975-1976” includes 700 digitized files. Exhibits are identified as “Submission” followed by a number with a “C”-prefix (e.g. Submission C585). The sub-series contains 627 digitized files, and 73 were not digitized due to the file folders being empty or for copyright reasons.

For Vancouver hearings exhibits, reference “R216-173-9-E, RG126 Date: 1976. Not digitized”. Records consist of exhibits from the Vancouver hearings of the MVPI held in May and June 1976. CV1-CV22 each denote a community exhibit with a description, person submitting and date. Hearings were also held in nine other centres in southern Canada (RG126, Vol. 9).

Formal hearings exhibits “R216-171-5-E, RG126 Date: 1975-1977” include 906 exhibits and are not digitized.

Fifty Years after the Mackenzie Valley Pipeline Inquiry: Listening to Voices (Part 2)

The Mackenzie Valley Pipeline Inquiry (MVPI), also known as the Berger Inquiry, was enacted fifty years ago in 1974 by the Canadian government. The purpose of the Inquiry was to investigate the potential impacts of the pipeline and report findings, which would be followed by appropriate actions. The final report (Volume One and Volume Two) was published in 1977. Library and Archives Canada (LAC) holds the original collection of Inquiry records, which are managed by the Government Archives Division.

This is part two of a three-part series on the MVPI. This blog will highlight two individuals who were central to the thoroughness of the Inquiry process as well as provide additional search methods for Inquiry records.

Part one presented a glimpse of the people and land of the Yukon and Northwest Territories (NWT) who would be affected by the proposed Mackenzie Valley Pipeline, along with a narrative of events that led up to the enactment of the Inquiry by the Canadian government. The final blog, part three, will focus on more specific searches for the records.

Commissioner Thomas R. Berger and interpreter and Inuk broadcaster Abraham Okpik

The Inquiry to study the potential environmental and socio-economic impacts of the proposed gas pipeline project was headed by Justice Thomas R. Berger. A former Justice of the B.C. Supreme Court, he possessed legal experience in First Nations issues. He had recently represented the Nisga’a and argued the Aboriginal title case Calder et al. v. Attorney-General of British Columbia, [1973] S.C.R. 313. This led to the 1973 Calder decision by the Supreme Court of Canada, which recognized that Aboriginal title to land existed prior to colonization and that Nisga’a land title had never been extinguished.

Abraham “Abe” Okpik, who was born in the Mackenzie River Delta, was an interpreter for the Inquiry in 1974. He also served as a linguistic representative for CBC to report on the Inquiry hearings. Okpik’s language skills combined with his life experiences were crucial for the Inquiry to establish communication and understanding with people from different Arctic communities.

In 1965, Okpik was the first Inuk to sit on the Council of the Northwest Territories (NWT). His legal surname at the time was “W3-554” due to the Canadian government system of using disc numbers to identify people in the North. Okpik eventually chose his new surname and was selected to head Project Surname in 1970. Under this project, Okpik visited Inuit camps and communities in northern Quebec and the NWT to record the surnames people wanted to replace their identification numbers. In 1976, Okpik was awarded the Order of Canada in recognition of his contributions to the preservation of the Inuit way of life and his work on the Berger Inquiry.

Conclusions of the Inquiry

Commissioner Berger summed up his thoughts in his November 1978 article on the MVPI with comments on industrialization, energy waste, the creation of wilderness parks and whale sanctuaries, and the need for humanity to reflect on its use of resources. He recognized the North as the last frontier and that the pristine and undeveloped areas were critical habitat for many creatures and their continued survival. He writes that in his MVPI report there are two sets of conflicting attitudes and values: “the increasing power of our technology, the consumption of natural resources and the impact of rapid change” versus “the growth of ecological awareness, and a growing concern for wilderness, wildlife resources and environmental legislation.”

The Inquiry concluded that a pipeline along the Mackenzie Valley to Alberta was feasible, but that it should only proceed after further study and after the settlement of Indigenous land claims. Based on this conclusion, a ten-year moratorium on construction was declared.

Voices speaking for land and life

The Inquiry was groundbreaking in its implementation of direct consultation that included hearings with the people of the communities that would be impacted by the project. They were aware that the pipeline would bring change and affect their relationship with the animals and the land. They spoke of their way of life and of knowledge that had been passed to them. Audio recordings of these oral testimonials are culturally invaluable. Their knowledge at that specific moment in time is preserved and available for future generations to hear.

Fred Betsina, a 35-year-old Dene from Detah Village, NWT, explained at the Detah Community Hearing why he did not want a pipeline. He told how he knew from trapping and hunting caribou that they were not able to jump over a 48-inch pipe—that they can’t jump higher than 12 inches, so instead they need to go around whatever is blocking their path. He stated that he wanted to see the land settlement claims settled before he saw a pipeline. His last comment was, “… us Indians. We got no money in the bank, nothing … The only money we got in the bank is the cash out in the bush … We get our meat from there, and fish is the cash … that’s what you call a bank here…”  He spoke for the wildlife, for his people and for his family’s needs.

The gathering of people from distantly located communities also presented opportunities to forge new friendships and strengthen alliances. The Inquiry gave a space for informal discussion on economic and political subjects.

Discovering MVPI collection materials

The records of the MVPI were transferred to the public archives of Canada in February 1978. All MVPI records are open to the public for research purposes, though not all records are digitally available.

The Mackenzie Valley Pipeline Inquiry (MVPI), also known as the Berger Inquiry, was enacted fifty years ago in 1974 by the Canadian Government. The purpose of the Inquiry was to investigate and report findings, which would be followed by appropriate actions. The final report (Volume One and Volume Two) was published in 1977. Library and Archives Canada (LAC) holds the original collection of the Inquiry records, and they are managed by Government Archives Division.

This is the first of a three-part series. Part one will revisit the events prior to the Inquiry and the areas the proposed project would impact. Part two will focus on people who were involved in the Inquiry, and part three will include specific details on how to search through the records of the MVPI.

The Mackenzie River is known as “Dehcho” (big river) by the Slavey (Dene), “Kuukpak” (great river) by the Inuvialuk and “Nagwichoonjik” (river flowing through a big country) by the Gwich’in (Dene). The colonial name of “Mackenzie” originated after the explorer Alexander Mackenzie visited the area in 1789.

The Mackenzie River winds through the Northwest Territories (NT), flowing northwest to the Mackenzie Delta. Just past the midway area of the river, immense limestone cliffs known as the Fee Yee (Ramparts) rise from the edge of the Mackenzie River. The river continues until it reaches the Mackenzie Bay at the Beaufort Sea in the Arctic Ocean. To the west of the river in NT and ending in the Yukon is the Mackenzie Mountain Range, a northern extension of the Rocky Mountains.

Treaty 11

The Dene had already given the name “Le Gohlini” (where the oil is) to Norman Wells, predating the arrival of colonial visitors. Tar was applied for waterproofing canoes and was made from small amounts of oil obtained from seepages. The sharing of their knowledge of the oil seepages resulted in Imperial Oil’s drilling program in 1919 and 1920. In 1920, oil was struck in the area of “Tutil’a” (“the place where the rivers meet” in Sahtu Dene; “Fort Norman” in English), and the construction of a small oil refinery followed. These events led to the signing of Treaty 11 in 1921 and 1922 by the Crown and representatives of the Dehcho, Tłı̨chǫ, Sahtu and Gwich’in peoples. The area covers 950 000 km2 of present-day Yukon, Northwest Territories and Nunavut. The Canadian Government’s interpretation of Treaty 11 secured title of these lands to the Crown, whereas the Dene saw the treaty as a peace and friendship agreement.

In 1968, a massive oil strike at Prudhoe Bay in Alaska moved energy investors to create proposals to move the oil and natural gas to southern United States and Canadian markets. The same year, the Task Force on Northern Oil Development was created, which resulted in the development of the federal government’s official northern pipeline guidelines, published in 1970 and expanded in 1972.

A pipeline proposal by Arctic Gas would have construction originating at Prudhoe Bay, Alaska on the Beaufort Sea to cross through the Yukon, Northwest Territories and Alberta and to include transportation of additional gas resources along the way to the United States.

As complex as the planning and construction of the infrastructure to support and build the pipeline was, the same complexity existed for the effects the pipeline would have on the environment, wildlife, and people of the land. The pipeline would also bring additional associated industrial development of an unknown scope. The result was that the Mackenzie Valley Pipeline was never built, although new projects would be proposed in its place.
