Wetland Conservation Programs in Canada

Canada's approach to wetland conservation is structured through a layered network of international treaties, federal legislation, provincial regulations, land trusts, and privately negotiated conservation agreements. No single program covers the full range of wetland types and ownership patterns found across the country. Instead, conservation is achieved through overlapping mechanisms that address different pressures at different scales.

The North American Waterfowl Management Plan

The North American Waterfowl Management Plan (NAWMP), first signed by Canada and the United States in 1986 with Mexico joining in 1994, remains the foundational continental framework for waterfowl and wetland conservation. The Plan set population goals for key waterfowl species and identified the habitat conditions — measured primarily in breeding pond numbers across the Canadian Prairies and boreal zone — that would be needed to reach those goals.

Over its four decades of operation, NAWMP has channelled substantial funding into habitat acquisition, easement purchase, and restoration across Canada. The Canadian component is coordinated through joint ventures — geographic partnerships that pool federal, provincial, and private resources to address specific regional habitat deficits. The Prairie Habitat Joint Venture, covering the three prairie provinces, has been the largest and most active of these, focusing on the restoration and protection of prairie potholes, seasonal wetlands, and associated upland nesting cover.

NAWMP is reviewed approximately every five years. The 2018 revision placed increased emphasis on the connectivity of wetland patches within the broader agricultural landscape, recognising that isolated potholes — even when individually protected — provide limited value when surrounded by intensively tilled fields that prevent movement between wetland patches.

The Ramsar Convention

Canada is a signatory to the Convention on Wetlands of International Importance, commonly known as the Ramsar Convention after the Iranian city where it was signed in 1971. Designation as a Ramsar site does not impose additional legal restrictions beyond those already in place under federal and provincial law, but it establishes an international expectation that the site will be protected and managed in accordance with the principle of "wise use" — allowing sustainable human activity while maintaining the ecological character of the wetland.

Canada had 37 Ramsar-designated wetlands as of early 2026, covering over 13 million hectares. Notable designations include the Peace-Athabasca Delta in Alberta — one of the largest inland freshwater deltas in the world and a critical staging area for waterfowl on the Central and Pacific flyways — and the Mer Bleue bog near Ottawa, a raised peat bog that supports a plant community more typically associated with subarctic conditions.

Information on all Canadian Ramsar sites is maintained by the Ramsar Secretariat and the Canadian Wildlife Service.

Provincial Wetland Policies

Jurisdiction over land use in Canada is primarily provincial, which means the legal framework governing wetland drainage, fill, and alteration varies considerably across the country. Ontario's provincial policy statement, for example, identifies significant wetlands as areas where development and site alteration are not permitted. Alberta's Water Act regulates activities in and adjacent to water bodies, including wetlands, through a licensing system. British Columbia's Riparian Areas Regulation requires setbacks from streams and wetlands in areas of urban development.

The effectiveness of these frameworks depends heavily on enforcement capacity and the definition of "significant" — a designation that typically applies only to wetlands that meet specific criteria related to size, species presence, or hydrological function. Many smaller wetlands, including the prairie potholes that collectively provide the majority of duck production across the Prairies, do not qualify for protection under significance-based frameworks and are vulnerable to drainage without regulatory review.

Ducks Unlimited Canada

Ducks Unlimited Canada (DUC) is the largest private land conservation organisation in Canada focused on wetland habitats. Founded in 1938 as an extension of the American Ducks Unlimited organisation, DUC works through a combination of land acquisition, conservation easements, and habitat restoration projects on private agricultural land. DUC engineers have designed and built thousands of water control structures across the Prairies that allow seasonal flooding of low-lying areas for waterfowl breeding, while maintaining drainage access for adjacent crop production during the growing season.

DUC's model of working with agricultural landowners rather than against them has been influential. Many of the wetland restoration projects completed in Manitoba, Saskatchewan, and Alberta in the 1980s and 1990s involved leasing or purchasing land from farmers who retained ownership of the surrounding crop fields. This approach reduced land-use conflict and allowed habitat improvements to proceed at scales that purely regulatory approaches could not have achieved in the same timeframe.

Detailed information on DUC's current restoration priorities and completed projects is available through the Ducks Unlimited Canada website.

Federal Protected Areas

A portion of Canada's most ecologically significant wetlands are protected within federal parks and wildlife areas administered by Parks Canada or the Canadian Wildlife Service. National Wildlife Areas — established under the Canada Wildlife Act — are specifically intended to protect habitat for migratory birds and other wildlife. They are not visitor-oriented parks but managed habitat units where human access may be restricted or prohibited during sensitive periods such as the nesting season.

Migratory Bird Sanctuaries, a separate category established under the Migratory Birds Convention Act, protect specific sites from disturbance during the nesting season but typically allow other land uses outside that period. Canada administers sanctuaries from the St. Lawrence estuary to the Mackenzie Delta, covering a range of wetland types and the waterfowl species associated with them.

Wetland Carbon and the Changing Policy Context

Wetlands — particularly peat-forming systems such as bogs and fens — store carbon in quantities that dwarf most other ecosystem types on an area-for-area basis. A drained peatland becomes a carbon source rather than a carbon sink, releasing accumulated organic matter accumulated over thousands of years within decades. This connection between wetland integrity and climate mitigation has elevated the policy profile of wetland conservation in Canada since the early 2020s.

Several provinces have incorporated wetland carbon into their greenhouse gas accounting frameworks, and federally funded natural climate solutions include wetland restoration as an eligible activity. The long-term effect of this policy shift on on-the-ground wetland protection is still being assessed, but it has introduced new funding streams and stakeholder interest in wetland management that were largely absent before.
