A plain-language read on which projects Ottawa is lifting off the federal review list, why it is happening now, and what still triggers a full assessment.
The federal government has amended the list of projects that automatically trigger a full federal review under the Impact Assessment Act, a change Ottawa says will shorten timelines for pipelines, cross-border and designated interprovincial power lines, and certain offshore renewable energy developments. The amendments to the Physical Activities Regulations — the instrument commonly called the Project List — were announced on September 9, 2026 under the government’s One Canadian Economy banner.
Three ministers put their names to the announcement: Dominic LeBlanc, Tim Hodgson and Julie Dabrusin. Their joint framing was that Canada can move major infrastructure faster without abandoning environmental safeguards or its obligations to Indigenous peoples — a balance that has been contested in Canadian project politics for the better part of a decade.
What the Project List Actually Controls
The Physical Activities Regulations are the gatekeeper document of Canada’s federal assessment system. They set out the categories and thresholds of activity that make a proposal a “designated project,” and therefore subject to a federal impact assessment before it can proceed.
If a project type is on the list, the federal process is engaged by default. If it is not, the proponent is generally left to the applicable regulator and to provincial or territorial approval regimes — which does not mean no oversight, but does mean one fewer parallel federal review running alongside everything else.
That is why amendments to this single regulation carry disproportionate weight. Changing a threshold or removing a category does not repeal any law; it quietly redraws the boundary of when the federal government inserts itself into a project’s approval path.
Pipelines, Power Lines and Offshore Renewables: The Three Areas Named
The announcement identified three groupings where reviews are being streamlined:
- Pipelines: Projects that fall under federal jurisdiction and are already subject to regulatory scrutiny through the energy regulator’s own approval process.
- International and designated interprovincial power lines: Transmission infrastructure that crosses the Canada–U.S. border or provincial boundaries, a category central to any east–west or north–south electricity build-out.
- Certain offshore renewable energy projects: A newer category tied to Canada’s emerging offshore wind ambitions, particularly on the Atlantic coast.
The public announcement summarised the direction of the change rather than reproducing the technical thresholds. The precise wording, capacity limits and any transitional provisions sit in the amended regulation itself, and proponents should read the regulatory text rather than the news release before drawing conclusions about a specific project.
Why Ottawa Is Moving on Permitting Now
The change is explicitly positioned as part of the One Canadian Economy agenda — the federal push to reduce internal barriers, speed up nation-building infrastructure, and reduce dependence on a single export market. That agenda gained urgency as the trade relationship with the United States deteriorated and Ottawa responded with counter-tariffs covering roughly C$27.6-billion of U.S. imports.
The logic Ottawa has advanced is straightforward: if Canada intends to sell more energy, electricity and critical minerals to Europe and Asia, it needs the physical infrastructure to move them, and it needs that infrastructure approved on a timeline investors can underwrite. That thinking also runs through the government’s deepening partnership with the European Union, where energy security has been a recurring theme.
Permitting duration has become the pinch point in that argument. Industry groups have long complained that a project can clear a technical regulator and still wait years for a separate federal assessment covering overlapping ground.
The Legal Backdrop the Amendments Are Working Around
The Impact Assessment Act arrived in 2019 as the replacement for the previous federal environmental assessment regime, and it has been contested almost continuously since. A 2023 Supreme Court reference opinion found that significant parts of the scheme, as they applied to provincially regulated projects, exceeded federal jurisdiction — a ruling that forced Ottawa back to the drafting table.
Amendments followed, and the practical work of narrowing federal reach has since shifted toward the regulations rather than the statute. Regulatory amendments move faster than legislation and attract less parliamentary attention, which is precisely the criticism levelled at the approach.
This is not an isolated adjustment either. Earlier changes carving out specific activities from federal assessment, including an oilsands exemption that moved through Ottawa with little fanfare, followed the same pattern of narrowing the Project List rather than rewriting the Act.
What Ottawa Says About Environmental Protection and Indigenous Rights
The ministers were direct on this point: the changes are presented as a reduction in duplication, not a reduction in standards. Projects removed from automatic federal designation remain subject to the requirements of their sector regulator, to federal statutes of general application, and to provincial or territorial approvals.
The government also reiterated that constitutional obligations to consult Indigenous peoples are unaffected by where a project sits on the list. The duty to consult flows from section 35 of the Constitution Act, 1982 and from case law, not from the Physical Activities Regulations.
Whether that reassurance holds in practice is the open question. The federal impact assessment process has functioned as a structured, funded venue for Indigenous participation; when a project falls outside it, participation depends on the regulator or province stepping into that role with comparable rigour.
Three Portfolios, One Announcement
The ministerial line-up is itself a signal. LeBlanc’s file covers intergovernmental affairs and the One Canadian Economy portfolio, Hodgson holds energy and natural resources, and Dabrusin holds environment and climate change.
Putting the environment minister’s name alongside the energy minister’s on a streamlining announcement is a deliberate attempt to pre-empt the charge that this is deregulation dressed in efficiency language. It also reflects the political reality that any change to the Impact Assessment Act family of instruments will be read through a climate lens regardless of how it is packaged.
What Provinces, Proponents and Critics Will Be Watching
Several things will determine whether this amendment is remembered as meaningful or marginal:
- Whether timelines actually compress: Removing a trigger only helps if the remaining regulatory path is itself efficient. Sector regulators now carry more of the load.
- How provinces respond: Alberta and Saskatchewan have pressed hardest for federal withdrawal from provincially regulated activity, while other jurisdictions have been more cautious.
- Litigation risk: Regulatory amendments are reviewable. Environmental organisations have shown a consistent willingness to test federal assessment decisions in court.
- Offshore wind execution: Atlantic offshore renewables are still at an early stage in Canada, and a lighter federal trigger matters only if projects reach financing.
- Investor read-through: Capital allocators watching Canadian energy and transmission will weigh regulatory certainty as heavily as approval speed.
For readers tracking Canadian infrastructure, the practical takeaway is narrower than the headline suggests. The Impact Assessment Act still stands, major projects still face federal review in many circumstances, and the change is a targeted adjustment to which activities are automatically pulled in — significant for the sectors named, largely invisible everywhere else.
Frequently Asked Questions
Does this repeal the Impact Assessment Act?
No. The Act remains in force. What changed are the Physical Activities Regulations, which determine which project types automatically require a federal impact assessment.
Which project types were named in the announcement?
Pipelines, international and designated interprovincial power lines, and certain offshore renewable energy projects.
Does a project removed from the list face no federal oversight at all?
Not necessarily. Such projects can still be subject to sector-specific federal regulation, other federal statutes, and provincial or territorial approval processes. The change concerns the automatic impact assessment trigger.
Are Indigenous consultation obligations affected?
The government stated that Indigenous rights and consultation obligations are maintained. Those duties arise from the Constitution and case law rather than from the Project List regulations.
Where are the exact thresholds set out?
In the amended regulatory text. The announcement described the direction of the changes; specific capacity thresholds and transitional rules were not itemised in the public summary.
