Public Registry Strategic Environmental Assessments
Conducting a Strategic Environmental Assessment is an important step in the early planning phase of offshore energy development. It helps us identify and highlight environmental sensitivities to be considered when establishing land licencing areas and when conducting future project-specific impact assessments. It’s also an important resource that the public can access to understand the sensitivities and learn more about environmental protection measures that should be taken into account to protect valued resources in the area covered by the assessment.
Our Public Registry of Strategic Environmental Assessments contain a collection of documents we maintain that are related to a specific Strategic Environmental Assessment Study area. These documents are developed to help us, operators, Indigenous groups, fishers, other stakeholders and the public learn more about environmental considerations for a specific offshore area, such as lands potentially under consideration for a Call for Bids area.
We use Strategic Environmental Assessment to make informed decisions and identify environmental sensitivities and any general restrictive or mitigative measures we should consider to protect the environment prior to our review of a project-specific environmental assessment completed by an operator during the activity authorization process.
You can access the following types of document in our public registry:
- Scoping documents (draft and final versions)
- Strategic Environmental Assessment (draft and final versions)
- Comments received on any draft documents

To view the map of the Middle and Eastern Scotian Slope and Sable Island Bank Areas, click the link below:
Location:
The SEA study area extends from the Gully Marine Protected Area (MPA) in the east to the deep slope waters of the Middle and Eastern Scotian Slope in the southwest.
Special Areas within the study area include Sable Island National Park Reserve, the Gully MPA, and the Western/Emerald Banks Conservation Area Marine Refuge. Sable Island is also protected as a Migratory Bird Sanctuary and an Important Bird Area (IBA).
Ecosystem:
There are fish, marine mammals, sea turtles, and bird species with special conservation status known to occur in the study area (e.g. the Northern bottlenose whale, blue whale, white shark, leatherback sea turtle and roseate tern, as well as other listed species). The SEA area includes critical habitat for the endangered Northern bottlenose whale. The SEA area also includes habitat forming benthic species, such as deep sea corals.
Commercial and Recreational Uses:
Other ocean uses in and around the study area include commercial fishing, shipping, tourism, scientific research, and military activity.
The main fish species currently targeted by commercial fisheries include, but is not limited to, commercially important invertebrate species such as shrimp, clam, snow crab, sea scallop, red crab and rock crab, as well as finfish such as Atlantic herring, bluefin tuna, Atlantic cod, Greenland halibut, haddock, mackerel, pollock, redfish and swordfish and other species. Lobster is currently unlikely to be targeted within the Study Area, though it may be in the future. Some harvesting of gray and harp seals may also occur in the area.
Indigenous Uses:
Indigenous fisheries in the study area may include the targeted commercial fisheries species listed above, with special emphasis on lobster, halibut and flounder. Migratory species (including fish, birds and mammals) that move through the study area could potentially be harvested by Indigenous communities in coastal areas through commercial fishing, food, social and ceremonial (FSC) fishing, commercial communal fishing or through other harvesting activities.

Some examples of groundfish found in the area include haddock, pollock, cod, skate, and flatfish. Indigenous communal commercial fisheries and Food, Social and Ceremonial fisheries may take place in the study area.
Longline fisheries, including tuna, swordfish and shark fisheries, are primarily concentrated along the shelf break and in deeper waters on the Scotian Slope.
