Carney names the Mackenzie Valley Highway his first 'national interest' project
The Building Canada Act's debut fast-track designation pits Arctic sovereignty against Indigenous consent
Summary
On 24 June 2026, the Mark Carney government moved to designate the Northwest Territories' Mackenzie Valley Highway as the first project of national interest under the Building Canada Act (Bill C-5), opening formal consultation — including with Indigenous governments — before final designation. The all-weather road would run Wrigley to Inuvik, connecting remote Dehcho, Sahtu and Beaufort-Delta communities and linking to the Dempster Highway, with an Arctic-sovereignty rationale. NWT Premier R.J. Simpson wants construction to start in 2027 and finish in about five years, against a prior 10-to-20-year horizon. It is the first use of the fast-track power Canada created to accelerate nation-building infrastructure, but Treaty 6 nations and others call C-5 an attack on treaty rights — the consent fight that shadows the build.
By the numbers
- 1st — national-interest designation under the Building Canada Act.
- Wrigley → Inuvik — the highway's route.
- ~5 years — Premier Simpson's target build time (was 10–20).
- 15 — projects referred to the Major Projects Office since 2025.
Why it matters
The designation is the test case for Carney's signature tool to override slow approvals in the name of economic sovereignty. How Ottawa handles Indigenous consultation here will set the template — and the legal exposure — for every fast-tracked project that follows.
