Wellers Bay National Wildlife Area

Wellers Bay National Wildlife Area (NWA) is a group of islands located near Trenton, Ontario, in Prince Edward County. The islands cover a total area of 83 hectares (ha).


This is a former training site used by the Department of National Defence, and unexploded bombs could remain. Public access is prohibited at Wellers Bay National Wildlife Area.

Wellers Bay NWA Public Information Notice

Please be advised that public access by land or water to the Wellers Bay National Wildlife Area (NWA) is prohibited year-round. This is to protect the fragile beach and dune ecosystems, sensitive wildlife habitats, and species at risk from human disturbance. There are also Unexploded Explosive Ordnance (UXO), such as bombs, grenades and flares, on the site. If disturbed, UXO can cause injury or death to humans and wildlife.

Any person found trespassing in the area may be charged and fined (up to $1,300) under the Wildlife Area Regulations of the Canada Wildlife Act.

Wellers Bay National Wildlife Area is located along the western shore of Prince Edward County in Ontario and is part of the Baldhead Peninsula that extends across the mouth of Wellers Bay. The NWA is home to federally listed species at risk and rare, provincially significant dune and coastal meadow marsh habitats, which are ecologically sensitive to any form of human disturbance.

From 1939 to 1953, the Department of National Defence used the Wellers Bay sand spit as a practice bombing range. To this day, UXO have not been entirely cleared from land and water and continue to pose a public health and safety risk.

Environment and Climate Change Canada’s Wildlife Enforcement Directorate has partnered with Crime Stoppers to combat wildlife trafficking and crimes involving migratory birds, species at risk and federally protected areas. Call Crime Stoppers 1-800-222-8477 (TIPS) to anonymously report wildlife crime or unlawful entry into Wellers Bay National Wildlife Area. You may be eligible for a reward of up to $2,000 from Crime Stoppers.

Only certain NWAs are open to the public, visit Current National Wildlife Areas for more information on Canada’s National Wildlife Areas and Migratory Bird Sanctuaries.


Wellers Bay NWA consists of Bald Island, Fox Island, Baldhead Island and Baldhead Beach. The islands are part of a large, roughly shaped peninsula on the north shore of Lake Ontario.

Wellers Bay is one of the last undeveloped sand spits on Lake Ontario. The bay has a long history of harboring bird life, and it serves as a stopover site or pass through for migrants during the spring and fall. The endangered piping plover has nested here in the past, and there is still suitable habitat available if they return. The threatened Least Bittern has been reported repeatedly within the NWA, most recently in 2022. In 1969, the Department of National Defence transferred Baldhead Peninsula, Baldhead Beach, Bald Island and Fox Island to the Canadian Wildlife Service to protect the wildlife habitat as an NWA.

The NWA protects rare wildlife habitats including open beaches, sand dunes, deciduous forest and wetlands. Wellers Bay NWA and surrounding areas also support a wealth of wildlife.

Wellers Bay provides habitat to species at risk such as:

Upland areas around Wellers Bay are important nesting grounds for many reptile species, birds and songbirds, including:

The sand spit and shallow marshes within Wellers Bay provide vital resting and feeding habitat for migrating waterfowl, including:

Grassland birds, including several species of sparrow, as well as loggerhead shrikes and upland sandpipers, are also common in the surrounding area.

Under the Canada Wildlife Act, NWAs are protected and managed in accordance with the Wildlife Area Regulations. The primary purpose of NWAs is to protect and conserve wildlife and their habitat. For this purpose and according to the legislation, all activities in an NWA that could interfere with the conservation of wildlife can be prohibited. Consequently, most NWAs are not accessible to the public and all activities are prohibited. However, some activities may be authorized through the issuance of permits as long as they are consistent with the management plan goals for the NWA. For more information, consult the NWAs Management and Activities section.

Access to the Wellers Bay NWA is prohibited to protect:

Research may be authorized by Canada Wildlife Act permit only, although such activities are limited due to the UXO risk that still exists in the area and can be completed only by individuals who have received UXO safety training.

Access to, and all activities within the NWA require a permit. More information on access and permitting for Wellers Bay can be obtained by contacting the Environment and Climate Change Canada regional office.
