Canada Scales Back Federal Environmental Reviews for Major Energy Projects

Prime Minister Mark Carney’s government has formally exempted interprovincial pipelines, transmission lines, and offshore renewable energy projects from review by the Impact Assessment Agency of Canada. The regulatory change, published in the Canada Gazette on September 9, 2026, shifts sole oversight of these major infrastructure developments to the Canada Energy Regulator.[1][3]

The overhaul dismantles a dual-track environmental review process that industry groups have long criticized as duplicative and politically fraught. By consolidating authority under the Calgary-based energy regulator, the federal government aims to establish a "one project, one review" framework, compressing the timeline for approving large-scale energy infrastructure.[1][2]

Under the amended Physical Activities Regulations, certain in situ oil sands extraction facilities and fossil fuel-fired power plants are also removed from the federal project list. The government stated the changes ensure federal impact assessments remain focused only on projects with the greatest potential to cause adverse effects within federal jurisdiction.[3]

Federal estimates project that the amendments will reduce the number of developments entering the broader impact assessment process from roughly 10 projects per year down to seven or eight. However, officials anticipate that a minimum of one major pipeline, one electrical transmission line, and one offshore wind project will be proposed over the next 10 years and will now proceed through the streamlined pathway.[1]

The Carney administration framed the deregulation as an economic necessity ahead of the $1-trillion Canada Investment Summit in Toronto next week. The regulatory filing highlighted strong support from the energy industry, noting that corporate actors view the exclusive regulatory model as a critical step toward improving certainty and attracting international capital.[3]

Environmental organizations immediately condemned the rollback, arguing the sector-specific regulator lacks the mandate to adequately evaluate broader ecological and social impacts. "The government has wiped its hands of doing a fulsome environmental review of the most polluting projects like oil pipelines and gas plants, at a time of unprecedented climate disaster," said Julia Levin, a spokesperson for Environmental Defence.[1][3]

Advocacy groups like Ecojustice have warned that bypassing the assessment agency could create "sacrifice zones" where endangered species and local ecosystems are compromised for corporate profit. During consultations this summer, the federal government acknowledged these concerns; its newly published "What We Heard" report noted that "many stakeholders oppose transferring primary assessment responsibilities… to sector regulators alone."[1]

The Impact Assessment Act was originally established in 2019 to broaden the scope of environmental reviews, but it faced intense pushback from resource-heavy provinces. In October 2023, the Supreme Court of Canada ruled that parts of the original legislation overstepped federal jurisdiction, prompting Ottawa to begin drafting the current amendments.[3]

The regulatory exemptions mark the first move in a broader legislative package the Carney Liberals plan to table this fall. As the government prepares to pitch international investors on Canadian infrastructure, the tension between rapid capital deployment and comprehensive environmental oversight will define the next era of the country's energy policy.[1][3]
