The NWT holds 25 of Canada's 34 critical minerals, faces diamond industry contraction, and is the focal point of the Arctic Economic and Security Corridor concept that would transform the economics of northern resource development.
The Northwest Territories is home to 25 of Canada's 34 critical minerals, world-class diamond deposits, significant gold, and the potential for rare earth development that could shift Canada's position in global supply chains for advanced technology and defence systems.1 Its population of 44,731 includes a very high proportion of Indigenous peoples across multiple distinct governance structures: the Tlicho Government, the Dehcho First Nations, the Aklavik and Inuvik regions of Inuvialuit settlement land, the Sahtu Secretariat, and others each govern their own territories with varying land claim and self-government arrangements.
The NWT's diamond industry, which produced the majority of Canada's gem diamonds, faced a significant contraction in 2024 with reduced output from the territory's diamond mines contributing to a 3.4% employment decline, the only territorial employment decrease that year.2 The two major producing mines, Ekati and Diavik, are in various stages of their operating lives, and the long-term future of NWT diamond production depends on whether new kimberlite discoveries justify the investment required. The shift in luxury goods markets, including growing synthetic diamond penetration in the gem market, adds commercial uncertainty beyond the geological question.
The Arctic Economic and Security Corridor, referenced by NWT's Minister of Industry in the January 2026 western Canada critical minerals MOU, represents the most ambitious infrastructure concept for unlocking NWT mineral development. An all-season road and potentially rail corridor connecting NWT's mineral districts to southern markets would transform the economics of projects that are currently unviable due to transportation cost. The federal government's NORAD modernization investment and the defence industrial strategy create a political moment when Arctic infrastructure investment can be justified on both economic and sovereignty grounds simultaneously.
The Northwest Territories has the most complex Indigenous governance landscape of any Canadian jurisdiction. Multiple First Nations, Metis, and Inuit peoples each have distinct legal relationships with the Crown, different stages of land claim and self-government negotiation, and different territorial footprints that overlap with each other and with the territorial government's jurisdiction. The Tlicho Government, with its settled land claim and self-government agreement, represents one model. The Dehcho First Nations, whose land claim negotiations have been ongoing for decades without resolution, represent another. The Inuvialuit Regional Corporation, with its 1984 Inuvialuit Final Agreement, represents yet another.
This multiplicity of governance structures is not a problem to be solved by simplification. It reflects the actual diversity of peoples and legal histories in the territory. But it creates a complex approval landscape for resource development that requires engagement with multiple distinct governments, each with their own timelines, priorities, and decision-making processes. Investors who treat this as regulatory friction rather than legitimate governance are consistently those who encounter the most difficulty. Investors who engage genuinely with each affected government as a partner in project design, benefit sharing, and environmental stewardship are those whose projects advance.
The Northwest Territories hosts two of the world's most productive diamond mines: Ekati (Arctic Canadian Diamond Company) and Diavik (Rio Tinto), both operating in the Lac de Gras kimberlite field approximately 300 km northeast of Yellowknife, collectively producing rough diamonds sorted and valued in Yellowknife before export to the Belgian, Indian, and Israeli cutting centres. Diavik's diamonds have among the highest average value per carat of any producing mine globally. Tungsten production at Canadian Tungsten's Cantung Mine historically supplied North American tool steel manufacturers. NWT gold deposits — including the legacy Giant Mine site and prospective greenfield projects near Yellowknife — are subject to ongoing exploration investment driven by high gold prices.
