In March 2026, the federal government referred four major projects to the Major Projects Office (MPO) as part of its Arctic Economic and Security Corridor strategy.
They include a 400 km all-season road through the Slave Geological Province, a 230 km gravel road to a deepwater Arctic port, a highway corridor from Wrigley to Inuvik reducing travel time between Yellowknife and Inuvik from 38 hours to roughly 23, and a hydro expansion that will double the Northwest Territories’ hydro capacity and connect 11 communities for the first time.
These are significant commitments. They are also extraordinarily complex ones — and that complexity is regulatory as much as it is logistical or financial.
What the MPO Is, and What It Isn’t
The Major Projects Office was created to accelerate nation-building projects by bringing together the people and processes needed to move faster without cutting corners. Once a project is referred to the MPO, it benefits from policy or regulatory challenge resolution, support to structure financing, and other efforts to reduce project risk.
Critically, the MPO works with proponents, federal departments, provinces and territories, Indigenous Peoples, and industry to identify and advance projects. It is a coordination mechanism, not a regulatory bypass. Projects still move through environmental assessment, Indigenous consultation, permitting, and approval processes. What the MPO changes is the quality of coordination and the speed at which blockers get resolved.
That distinction matters. The bottleneck on large infrastructure projects in Canada is rarely the absence of will. It is the volume and complexity of the regulatory record that needs to be built, understood, and defended.
The Regulatory Work Beneath These Projects
Consider what successfully advancing even one of these four projects actually requires.
The Grays Bay Road and Port project has been in development since 2018. The proponent, West Kitikmeot Resources Corporation, is advancing a ~230 km all-season gravel road to a deepwater port and airfield at Grays Bay, which will have dual civilian-military use and enable new resource exploration including copper, zinc, and gold. A project of that scope — crossing federal, territorial, and Nunavut jurisdictions, touching Indigenous land rights, involving environmental assessment, transportation permitting, and defence considerations — generates an enormous regulatory record.
The same is true for the Taltson Hydro Expansion. The project will build an additional 60-megawatt facility, connect the North and South Slave Lake electrical grids via a 320-kilometre transmission line including a submarine cable under Great Slave Lake, reduce greenhouse gas emissions by up to 240,000 tonnes, and is being advanced collaboratively by NWT Métis Nation, Akaitcho Dene First Nations, and Salt River First Nation. That level of multi-party collaboration, environmental scope, and technical complexity produces thousands of pages of applications, evidence, IR sets, and regulatory submissions.
For every project in this list, the teams doing the regulatory work — proponents, Indigenous partners, legal counsel, environmental consultants, engineers — will spend significant time doing three things: researching what has come before, producing the filings that move the process forward, and validating that those filings meet the standard required.
Where Regulatory Intelligence Tools Make a Difference
This is the work Ultimarii was built for.
When a proponent team needs to understand how a regulator has treated a specific issue in prior proceedings, or how a comparable project handled Indigenous consultation evidence, or whether their application chapters are internally consistent with commitments made earlier in the record — that is not a problem of effort or expertise. It is a problem of scale. The record is simply too large and too distributed for manual search to be efficient or reliable.
The projects referred to the MPO in March 2026 will each generate multi-year regulatory records. Many will draw on existing decisions and precedents from CER, IAAC, AER, and territorial bodies. Teams will need to compare prior applications, track how intervenors have historically engaged on similar issues, and build evidence packages that hold up under scrutiny.
The MPO can streamline coordination. What it cannot do is reduce the volume or complexity of the underlying regulatory work. That work still needs to be done — accurately, traceably, and at a pace that matches the ambition of the projects themselves.
The teams that will be most effective are the ones with the tools and workflows to move through that work efficiently without sacrificing quality. That is the problem Ultimarii exists to solve.
Ultimarii is a Calgary-based AI platform purpose-built for complex regulatory work. Our tools help proponents, legal teams, and consultants research precedent, produce regulatory work products, and validate submissions across large, document-intensive proceedings.
