Canada Advances Decades-Old Northern Highway Project
A highway envisioned nearly 70 years ago is moving forward again as Canada invests in a long-planned road through the Northwest Territories.
Canada has announced C$405 million for the proposed Mackenzie Valley Highway, a long-planned all-season gravel road that could eventually connect communities along the Mackenzie River with Canada’s Arctic coast. The money comes from the federal government’s C$1-billion Arctic Infrastructure Fund.
The full vision is an approximately 800-kilometre corridor from Wrigley north towards Inuvik. Some communities along the proposed route currently depend on aircraft, summer barges and seasonal winter roads for much of their transport and resupply.
The C$405 million will fund only specific components of the project, including environmental assessment and design work, construction of one bridge, preparatory work on two others and a six-kilometre all-season access road. Completing the highway would require further assessment, regulatory approvals and funding.
A road discussed for generations
The idea dates back to 1958, when Canada began considering an all-season highway through the Mackenzie Valley to the Arctic coast. Construction north from Fort Simpson began in the 1970s, was later halted and eventually resumed, with the all-season road reaching Wrigley in 1994.
Progress farther north has since come in smaller steps through studies, environmental assessment and construction of related infrastructure. In 2026, the project entered another significant stage, with new federal funding and efforts to expand its scope.
Ottawa says the highway could make community resupply more reliable, improve access to health and emergency services and support economic development. It also presents the project as dual-use infrastructure that could contribute to Canada’s Arctic security and sovereignty.
Climate change is also part of the case for the road. The territorial government says thawing permafrost, shorter winter-road seasons and low water levels are making existing transport links less reliable.
Local support and concerns
Indigenous governments along the corridor have established a coordinated framework to participate directly in the highway’s governance, planning, co-design and long-term direction.
Community and Indigenous input has already influenced the proposed route. Among other changes, planners shifted sections to avoid a moose pasture and to move the highway farther from a site of cultural importance to local Indigenous communities.
The ongoing environmental assessment considers social and economic effects as well as impacts on the natural environment. These include employment, cost of living and community well-being, alongside wildlife, harvesting, water and traditional land use. Communities have also raised concerns that permanent road access could make drugs and alcohol easier to bring into some settlements. The territorial government says it is working with communities to prepare for these and other pressures associated with year-round road access.
For now, the Mackenzie Valley Highway remains under development. But 2026 has brought substantial new funding and a renewed push to a project that northern communities and governments have been discussing and advancing in different forms for generations.
