Îles de Contrecoeur National Wildlife Area
Îles-de-Contrecoeur NWA, landscape.
The Îles-de-Contrecoeur National Wildlife Area (NWA) is made up of 22 small and low-lying islands surrounded by marshes and seagrasses distributed along a 10-km stretch of the St. Lawrence River 35 km northeast of Montréal. Established in 1981 by Environment and Climate Change Canada, its purpose is to conserve a remarkable network of emergent and submerged seagrass beds and islands with high nesting potential for waterfowl in the Montréal region.
With its landscape of grassy plains, the wildlife area is dotted by low-lying alluvial islands, many of which become fully submerged during the spring freshet. Exposed to seasonal variations in water levels in the St. Lawrence, these islands are covered mainly by high grasses and, in some cases, a few trees such as willow, Silver Maple and Red Ash. Reed Canarygrass, which is popular among waterfowl for nesting, covers entire islands in places.
Swathes of swampland populated with cattail, arrowhead and submerged water-milfoil beds lie around the islands, linking them together and providing food to thousands of ducklings, adult ducks and other water birds during breeding and migration. The wildlife area is home to more than 205 plant species, as well as 78 bird and 12 mammal species. A number of species at risk, including the Short-eared Owl, are also observed here on occasion.
These islands are the largest nesting site in Quebec for the Gadwall and nearly a dozen other dabbling duck species, including Northern Pintail, American Wigeon and Mallard. Other species observed in the NWAinclude American Bittern, Virginia Rail, Marsh Wren, Wilson's Phalarope, Red-winged Blackbird, Swamp Sparrow, and Yellow Warbler. The archipelago additionally supports an impressive colony of approximately 13 000 pairs of Ring-billed Gulls. With respect to mammals, the muskrat is a common sight in the Contrecoeur islands. Striped Skunks, raccoons and Red Foxes are also observed, along with shrews, voles and bats.
The wildlife area is exposed to a number of threats and management challenges, including disturbance due to unauthorized activities on the islands, the presence of invasive alien species like Common Reed and Purple Loosestrife, the discharge of heavy metals into the St. Lawrence, and accidental spills.

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 habitat. For this purpose, and according to the legislation, Environment and Climate Change Canada can prohibit all activities in a NWAthat could interfere with the conservation of wildlife. Consequently, most NWAs are not accessible to the public and all activities are prohibited. Nonetheless, Environment and Climate Change Canada 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, access to the Îles-de-Contrecoeur NWA is generally prohibited except under the authority of a permit issued by the Minister, such as for waterfall hunting in the fall.
In addition, permits may be issued for research activities in keeping with the priorities set out in the management plan for the wildlife area. Permits may also be issued for other conservation activities such as surveys, or the enhancement or restoration of habitat.
Priority will be given to collaborative activities with local agencies and organizations to promote the protection and the conservation of wildlife species and their habitat 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.

Environment and Climate Change Canada would like to inform the public that the Îles de Contrecoeur NWA -- located in the heart of the St. Lawrence River, 1 kilometres (km) north of the city of Contrecoeur -- is a protected area. Since its creation in
1981, the NWA has been protecting migratory birds, wildlife and wetland habitats, as well as species at risk.
To protect the area, the Department is informing people of their obligation to follow certain rules, as dictated by the Canada Wildlife Act and its corresponding regulations. Anyone who fails to follow these rules or obey the laws in effect may be subject to fines and prosecution.
The migratory bird hunting is permitted on the NWA in the fall according to the periods, conditions, places and hunting gear under the regulations.
Without a permit issued by the Minister, it is strictly prohibited for anyone in the area to:
- Circulate (on foot, on any mode of transportation) except on foot during the waterfowl hunt (migratory birds) in the fall;
- hunt other wildlife than migratory birds, in which case you must be in compliance with the time periods, conditions, locations and hunting instruments authorized under the regulations in effect;
- 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;
- dump or deposit any trash.
For complete information on all applicable regulations, please consult the Canada Wildlife Act; Wildlife Area Regulations; Migratory Birds Convention Act, 1994; and Species at Risk Act at Environment and Climate Change Canada website.
