Environmental Assessments in Atlantic Canada: Four Frameworks, One Barrier to Growth

Environmental Impact Assessments are often one of the first regulatory hurdles facing major projects in Atlantic Canada. And they are anything but consistent.

As the graphic shows, timelines and expectations vary widely by province. Newfoundland and Nova Scotia have statutory commitments on their promised timelines, while New Brunswick and PEI do not. Some of the recent onshore wind projects in Nova Scotia were approved in roughly two weeks, highlighting the provincial priorities at play, and yet other projects in the Atlantic region have been at the discussion table for years.

For project proponents, this is a big cost driver. Scaling across Atlantic Canada means working through four separate assessment frameworks, four departments, and four sets of expectations. That translates into duplicative effort in regulatory strategy, stakeholder engagement, and internal capacity-building.

This fragmentation isn’t unique to environmental assessments. It reflects a broader pattern across the region. Crux Energy Consulting’s recent report, An Atlantic Canadian Energy Future, highlights that while Atlantic provinces are physically interconnected, planning and decision-making remain largely provincial. The result is duplication, higher system costs, and missed economic opportunities. All of which lead to a cycle of stalled economic development.

There are early signs of progress. Nova Scotia has recently signaled interest in working more closely with the federal government toward a “one project, one assessment” approach, just as New Brunswick did last year. Reducing overlap between provincial and federal reviews is a practical step that could shorten timelines and improve predictability. But the opportunity is broader than that. Even partial alignment across provinces, such as standardized documentation, clearer service standards, or shared milestones, would reduce friction for proponents without requiring full regulatory harmonization.

It’s also important to understand what the timelines in the graphic don’t show. Formal EIA clocks typically start at project registration, but getting to registration can take significant time. Proponents often spend months (or years) on baseline studies, early engagement, and iterative discussions with communities, governments and regulators before a project is formally submitted. These pre-registration phases are inconsistent across jurisdictions and can materially extend total project timelines.

EIAs are just one piece of the approvals puzzle. Projects still need to secure permits, complete additional studies, and navigate other regulatory requirements that vary province by province. Each step represents another opportunity for better coordination.

Effective collaboration doesn’t always require sweeping reform. Incremental alignment can materially improve how projects move forward in Atlantic Canada. Small wins can be found everywhere.
