Canada’s federal government has taken a significant step toward expediting two major Arctic infrastructure projects—the Mackenzie Valley Highway and the Grays Bay Road and Port—by launching a public consultation process to designate them as projects of national interest under the Building Canada Act. The announcement, made by Natural Resources and Energy Minister Tim Hodgson in Yellowknife, N.W.T., on Wednesday, sets the stage for a streamlined federal permitting track that could see these projects fast-tracked by fall 2026.
What the Designation Means
Listing under the Building Canada Act, passed as part of Bill C-5 in June 2025, places the projects into a unique legislative framework designed to accelerate nation-building infrastructure. While the projects must still undergo treaty-based impact assessments and regulatory processes under modern treaties, the designation provides a pathway to faster federal permitting. The government has already invested more than $100 million in the Mackenzie Valley Highway and tens of millions in the Grays Bay Road and Port project.
The two Arctic projects were previously referred to the Major Projects Office (MPO) in March, which acts as a concierge to manage the federal review process. However, the new designation under the Building Canada Act goes further, offering what the government describes as “immediate, upfront confidence that certain key federal regulatory authorizations and permits will be granted.”
Criteria for National Interest Designation
To be listed as a project of national interest, a project must meet five criteria: strengthening Canada’s autonomy, resilience, and security; creating economic benefits for the country; having a high likelihood of successful execution; advancing Indigenous people’s interests; and contributing to clean growth. Minister Hodgson emphasized that these projects represent a shift in Canada’s regulatory landscape. “Unlocking Canada’s economic potential requires bold action that clearly demonstrates we are ready to build big in this country again,” he said during a press conference. “The initiation of this process marks a major shift in how we accelerate nation-building infrastructure.”
Hodgson acknowledged that the announcements “probably sound like a lot of jargon,” but stressed the underlying message: Canada is ready to build “big things again” and that “the North is important.”
Deep Geological Repository Also Listed
In addition to the two Arctic projects, Hodgson announced that the federal government intends to list the Nuclear Waste Management Organization’s Deep Geological Repository—an underground vault for storing nuclear waste located in Ontario—under the same act. This would be the first time projects are designated under the Building Canada Act, signaling a new era of federal support for major infrastructure.
Hodgson said the government aims to launch consultations in the coming weeks, with the goal of officially designating the projects by the fall. The streamlined process is expected to reduce delays and provide certainty for investors and Indigenous communities involved in these long-standing initiatives.
Impact on Arctic Development
The Mackenzie Valley Highway and Grays Bay Road and Port have been in planning for decades, with the federal government already investing heavily. The highway would connect the Mackenzie Valley to the rest of Canada’s road network, while the Grays Bay project aims to provide a deep-water port and road access to the Arctic coast. Both are seen as critical for economic development, resource extraction, and improving the quality of life in remote northern communities.
The designation process under the Building Canada Act is expected to accelerate permitting, though the government noted that treaty-based impact assessments still apply. For the Deep Geological Repository, listing would provide upfront confidence that key federal permits will be granted, streamlining a project that has faced regulatory hurdles.
