Estuary Islands National Wildlife Area (NWA) is made up of ten rocky islands or portions of islands scattered over some 120 kilometers between Kamouraska and Rimouski in the heart of the St. Lawrence Estuary. This 404-hectare protected area was established in 1986 by Environment Canada to protect important nesting sites for migratory birds, particularly colonial seabirds and especially the Common Eider.

Its rocky islands are covered by Balsam Fir, White Birch stands and White Spruce stands and herbaceous vegetation. They are bordered by large mudflats or rocky flats that are occupied by communities of mixed algae. A hundred or more species of birds visit the NWA, a large proportion of which also nest there. The islands are also home to nearly a dozen mammal species. Species at risk frequenting the wildlife area and its surroundings include the Peregrine Falcon, Red Knot and Barrow's Goldeneye.

The wildlife area accommodates large colonies of seabirds such as the Common Eider, Razorbill, Black Guillemot, Great Blue Heron, Black-crowned Night-Heron, Black-legged Kittiwake, Double-crested Cormorant, Great Black-backed Gull, and Herring Gull. These birds are highly sensitive to human disturbance. The colony of Common Eiders on Île Bicquette counts more than 7 000 pairs, making it one of the largest colonies for that species in North America. Some of the NWA islands are also frequented by the largest colonies of Razorbills and Black Guillemots in the St. Lawrence Estuary. During migration periods, many waterfowl species, including the Brant, Snow Goose, Black Scoter, Surf Scoter, Oldsquaw and Black Duck, descend upon the islands, bordering flats and adjacent waters and can sometimes be observed in the hundreds or thousands. The most common land mammals in the wildlife area are the Muskrat, Red Fox and Snowshoe Hare. The Grey Seal and Harbour Seal are often found along the shores.

Estuary Islands National Wildlife Area is exposed to a range of threats and presents management challenges, including wildlife diseases, the disturbance of colonial birds due to predators and human activities, the presence of invasive exotic plant species, and the risk of accidental oil spills in the St. Lawrence.

More information on Estuary Islands NWA is provided in the summary table below.


NWAs are protected and managed according to the Wildlife Area Regulations under the Canada Wildlife Act. The primary purpose of NWAs is the protection and conservation of wildlife and their habitats. For this purpose, and according to the legislation, Environment and Climate Change Canada can prohibit all activities in a NWA that could interfere with the conservation of wildlife. Consequently, public access and activities are prohibited in most NWAs. Nonetheless, the Ministry has the ability to authorize some activities, whether through public notice or the issuance of permits, as long as these are consistent with the management plan goals for the NWA. For more information, consult the NWAs Management and Activities section.

Due to the fragility of wildlife species and island environments, public access to Estuary Islands NWA is prohibited except for one of the islands, Le Pot du Phare. Visitors have access through the transportation service offered by Duvetnor and authorized by Environment and Climate Change Canada, from mid-July to mid-October, following the seabird nesting season.

Permits may be issued for research activities in keeping with the priorities set out in the management plan for the wildlife area or for other conservation activities such as surveys, or the enhancement or restoration of habitats.

Priority will be given to collaborative activities with local agencies and organizations to promote the protection and the conservation of wildlife species and their habitats in the NWA. For example, initiatives could be launched or continued with the following entities: universities or research centers to address gaps in scientific knowledge; the province to implement recovery measures for species at risk (particularly those falling under provincial jurisdiction); or non-governmental organizations or municipal authorities to build public awareness of the wildlife area's objectives.

More information on access and permitting for Estuary Islands NWA can be obtained by contacting the Environment and Climate Change Canada regional office.

Notice from Environment and Climate Change Canada

Download PDF version - Notice from Environment and Climate Change Canada [Estuary Islands] (PDF; 141 KB)

Environment and Climate Change Canada would like to inform the public that the Estuary Islands NWA--a string of a dozen islands located in the middle of the St. Lawrence Estuary in the municipalities of Rimouski, Saint-André and Kamouraska--is a protected area. Since its creation in 1986, the NWA has been protecting wildlife and the nesting sites of migratory birds in the area, particularly those of seabird colonies.

To protect the area, the Department is informing visitors to areas around NWA islands of their obligation to follow certain rules, as dictated by the Canada Wildlife Act and its corresponding regulations. Anyone who neglects to follow these rules or obey the laws in effect may be subject to fines and prosecution.

Nature viewing and hiking are authorized in designated areas on Le Pot du Phare island.

Without a permit issued by the Minister, it is strictly prohibited for anyone in the NWA to (see section 3.(1) of the Wildlife Area Regulations):

  • hunt or fish;
  • destroy or remove a plant;
  • allow any domestic animal to run at large;
  • swim, picnic, camp or carry on any other recreational activity or light a fire;
  • operate any mode of transportation;
  • dump or deposit any trash.

For complete information on all applicable regulations, please consult the Canada Wildlife Act, Wildlife Area Regulations, 1994 Migratory Birds Convention Act, and Species at Risk Act at Environment and Climate Change Canada website.
