Ottawa Proposes Shifting Pipeline Reviews to Energy Regulator, Cutting IAAC Out of the Process
According to The Canadian Press via Global News, the federal government is proposing to shift authority for reviewing interprovincial pipelines, transmission lines, and offshore renewable energy projects from the Impact Assessment Agency of Canada to the Canada Energy Regulator — a change that would unwind the centralized review model the Liberals built eight years ago.
The proposal enters a 30-day consultation period and signals the most concrete regulatory reform move yet on major project approvals. The timing aligns with mounting pressure from the IEA, Bank of Canada, and energy executives who have warned that regulatory delays are costing Canada investment and market access.
What the Proposal Changes
Under the proposed framework, the CER — an agency that already regulates pipelines, power lines, and energy exports — would absorb the review function for interprovincial projects. The IAAC, created in 2019 under Bill C-69 as a one-stop environmental and impact assessment shop, would see its pipeline and transmission mandate substantially pared back.
The practical shift is significant. The CER has technical expertise in pipeline engineering, safety, and operations that the IAAC was never structured to develop. Putting the same regulator that governs pipeline tariffs, safety, and abandonment in charge of project reviews could shorten timelines by eliminating the handoff between agencies.
A second proposal would let cabinet decide whether a pipeline project is in the public interest before the review is completed — potentially collapsing the political approval lag that has historically added months or years after a technical review concludes.
Ottawa is also planning a Crown consultation hub within the IAAC to better coordinate with Indigenous communities and provinces, and is pursuing legislative changes to reduce major project review times to one year. The government introduced legislation a year ago to cut timelines from five years to two; this would halve that target again.
What It Means for Subcontractors
- Pipeline project backlogs could unlock. Interprovincial pipeline proposals that have been stalled in review — including new export capacity and connection projects — could move to FID faster if the CER review model proves more efficient. Pipeline construction contractors, welders, and integrity crews in Alberta and BC should monitor the consultation process for signals on specific projects.
- Transmission line inclusion broadens the impact. The proposal covers transmission lines as well as pipelines, which means electrical contractors and line crews working on interprovincial grid projects could see faster mobilization timelines.
- One-year target is ambitious. Cutting reviews from five years to one is a steep reduction. If achieved, it would compress the gap between project announcement and ground-breaking, creating shorter, more intense mobilization cycles for field contractors.
- Indigenous consultation hub could reduce community-related delays. Clearer coordination on consultation may reduce the stop-start pattern that has bedevilled major projects like Coastal GasLink and Trans Mountain, where field crews have faced repeated work stoppages tied to unresolved consultation issues.
- Cabinet pre-approval changes the risk calculus. If cabinet can signal public interest before review completion, project proponents may begin pre-mobilization and early works sooner — creating earlier revenue opportunities for civil, clearing, and site-prep contractors.
